Occlusion development after premature loss of deciduous anterior teeth: preliminary results of a 24-month prospective cohort study

ABSTRACT Objective: This study aimed to evaluate occlusion development after premature loss or extraction of deciduous anterior teeth, by means of a prospective cohort study. Methods: Fifteen infants and children aged 1 to 5 years old were longitudinally assessed (with loss or extraction of deciduous anterior teeth [n = 9], and without tooth losses [n = 6]). Photographs and dental casts at the baseline and after 24 months of follow-up were performed. Dental casts were scanned, and linear measurements were made on the digitalized models (missing tooth space, arch perimeter, arch length, arch width, intercanine length and intercanine width). The t-test was used for groups comparisons (α = 0.05). Results: Individuals' mean age at baseline was 2.93 (± 1.18) years. No statistically significant differences were observed in the missing tooth space in the group with tooth loss during the 24 months of follow-up (p > 0.05). Arch perimeter, arch length, arch width, intercanine length and intercanine width did not show differences between the groups (p > 0.05). Qualitative photographic evaluation revealed other changes in the dental arches and occlusion, such as exfoliation and eruption of deciduous teeth, eruption of permanent teeth, self-correction or establishment of malocclusion, among others. Conclusion: The results suggest that the premature loss of deciduous anterior teeth does not affect the perimeter, length and width of the dental arches; however, other alterations that lead to malocclusion could be established.

RESUMO Objetivo: Este estudo teve como objetivo avaliar o desenvolvimento da oclusão após perda prematura ou extração de dentes decíduos anteriores, por meio de um estudo de coorte prospectivo. Métodos: Quinze bebês e crianças de 1 a 5 anos foram avaliados longitudinalmente (com perda ou extração de dentes anteriores decíduos [n = 9] e sem perdas dentárias [n = 6]). Foram realizadas fotografias e modelos dentais no início e após 24 meses de acompanhamento. Os modelos dentários foram escaneados e medidas lineares foram feitas nos modelos digitalizados (espaço dentário perdido, perímetro da arcada, comprimento da arcada, largura da arcada, comprimento intercaninos e largura intercaninos). O teste t foi utilizado para comparações entre grupos (α = 0,05). Resultados: A média de idade dos indivíduos no início do estudo foi de 2,93 (± 1,18) anos. Não foram observadas diferenças estatisticamente significativas no espaço dentário perdido no grupo com perda dentária durante os 24 meses de acompanhamento (p > 0,05). O perímetro da arcada, comprimento da arcada, largura da arcada, comprimento intercaninos e largura intercaninos não apresentaram diferenças entre os grupos (p> 0,05). A avaliação fotográfica qualitativa revelou alterações nas arcadas dentárias e na oclusão, como: esfoliação e erupção de dentes decíduos, erupção de dentes permanentes, autocorreção ou estabelecimento de má oclusão, entre outras. Conclusão: Os resultados sugerem que a perda prematura de dentes anteriores decíduos não afeta o perímetro, comprimento e largura das arcadas dentárias; entretanto, outras alterações que levam à má oclusão poderiam ser estabelecidas.

Research progress on dental materials for preventing root caries / 口腔疾病防治

@#The high incidence and untreated rate of root caries, a common and frequently occurring oral disease with challenging treatment in elderly individuals, is the main cause of tooth loss among elderly people, as rapid development results in pulpitis and periapical periodontitis or residual crown and root, which has been regarded as one of the common chronic oral diseases seriously affecting the quality of life of elderly people. Thus, early intervention and prevention are important. Traditional dental materials for preventing root caries have been widely used in clinical practice; however, they have the disadvantages of tooth coloring, remineralization and low sterilization efficiency. A series of new dental materials for preventing root caries have gradually become a research hotspot recently, which have the advantages of promoting the mineralization of deep dental tissue, prolonging the action time and enhancing adhesion. Future caries prevention materials should be designed according to the characteristics of root surface caries and the application population and should be developed toward simplicity, high efficiency and low toxicity. This review describes current research regarding anti-caries prevention material application, serving as a theoretical underpinning for the research of root caries prevention materials, which is important for both promotion in the effective prevention of root caries and improvement in the status of oral health and the quality of life among old people.

Clinical application of lithium disilicate glass ceramic cantilever resin-bonded fixed partial denture in the restoration of single anterior tooth loss / 口腔疾病防治

Objective@#To investigate the clinical effect of lithium disilicate glass ceramic cantilever resin-bonded fixed partial dentures (CRBFPDs) on single anterior tooth loss to provide a reference for the selection of restoration methods for single anterior tooth loss.@*Methods@#This study was reviewed and approved by the Ethics Committee, and informed consent was obtained from the patients. Forty-two patients with less than two anterior teeth with monomaxillary loss were included in this study. After 6 months, 1 year, 2 years, and 3 years, the aesthetic and functional effects of the restorations and the periodontal health status were evaluated, and the visual analog scale (VAS) was used to assess patient satisfaction.@*Results@#During the observation period, the connector fractured in one case within 3 months. One case had debonded within 2 years. The aesthetic restoration effect of all lithium disilicate glass ceramic CRBFPDs was categorized as Class A. The periodontal health was good, there was no clinical absorption in the soft and hard tissues of the abutment or subbridge, periodontal status according to the evaluation indices was classified as class A, and the total satisfaction rate of the patient was 100%.@*Conclusion@#For single anterior tooth loss patients, lithium disilicate glass ceramic cantilever resin-bonded fixed partial denture can achieve the restoration effect of less invasion, better adhesion, aesthetics, comfort and good biocompatibility. With high patient satisfaction, it can be considered an ideal restoration method for replacing a single anterior tooth.

Classificação das lesões corporais do artigo 129 do código penal brasileiro de acordo com os acórdãos do superior tribunal de justiça no ano de 2011 a 2022 / Classification of body injuries of article 129 of the Brazilian Penal Code according to the judgments of the superior court of justice from 2011 to 2022

Em função dos crescentes casos de violência em nosso país, sejam eles interpessoais ou de trânsito, tem se observado um aumento nos casos de processos decorrentes de lesões corporais. Devido ao fato de a face ser uma região muito exposta e pouco protegida, esta se torna uma região em que traumas são prevalentes, decorrentes de atos de agressão, quedas ou acidentes de trabalho/esporte. Este trabalho objetivou analisar as decisões dos acórdãos quanto à quantificação dos danos decorrentes de lesões corporais envolvendo o órgão dentário. Trata-se de um estudo observacional transversal com abordagem quantitativa de levantamento retrospectivo das decisões dos acórdãos do Superior Tribunal de Justiça nos anos de 2011 a 2022 relacionados a processos penais envolvendo lesões corporais, baixadas e impressas através de busca eletrônica. Dos 17 acórdãos analisados, 5 mantiveram a mesma classificação (lesão corporal grave-debilidade permanente) e 12 desclassificaram deformidade permanente para debilidade permanente - Inciso III do 1° do art. 129. De acordo com os acórdãos analisados, pode-se concluir que diferente da doutrina literária, a perda dental não é considerada como deformidade permanente quando o caso é analisado no âmbito do Superior Tribunal de Justiça brasileiro

Due to the growing cases of violence in our country, whether interpersonal or traffic, there has been an increase in cases of lawsuits resulting from bodily injury. Due to the fact that the face is a very exposed and poorly protected region, it becomes a region where traumas are prevalent, resulting from acts of aggression falls or work/sport accidents. This study aimed to analyze the decisions of the judgments regarding the quantification of damages resulting from bodily injuries involving the dental trauma. This is a cross-sectional observational study with a quantitative approach of a retrospective survey of the decisions of the Superior Court of Justice rulings in the years 2011 to 2022 related to criminal proceedings involving bodily harm, downloaded and printed through an electronic search. Of the 16 judgments analyzed, 5 maintained the same classification (serious bodily injury-permanent weakness) and 11 disqualified permanent deformity for permanent weakness - Item III of the 1st of art. 129. According to the judgments analyzed, it can be concluded that, unlike literary doctrine, tooth loss is not considered a permanent deformity when analyzed for the Brazilian Superior Court of Justice

Razões e consequências das perdas dentárias em adultos e idosos no Brasil: metassíntese qualitativa / Reasons for and consequences of tooth loss in adults and elderly people in Brazil: a qualitative metasynthesis

Resumo O objetivo foi analisar e sistematizar evidências levantadas por estudos qualitativos sobre razões e consequências de perdas dentárias em adultos e idosos no Brasil. Foi executada revisão sistemática da literatura de pesquisas de métodos qualitativos, e metassíntese dos resultados. A população de estudo foi de adultos acima de 18 anos e idosos brasileiros. Foi realizada busca nas bases de dados BVS, PubMed, Scopus, Web of Science, BBO, Embase, EBSCO e SciELO. A síntese temática definiu oito temas analíticos sobre razões das perdas dentárias e três temas analíticos sobre as consequências. A dor dentária, o modelo de atenção, a situação financeira e o desejo de reabilitação protética foram fatores determinantes para as exodontias. Houve reconhecimento da negligência com o cuidado bucal e da naturalidade das perdas dentárias ligada à velhice. Dentes perdidos causaram impactos psicológicos e fisiológicos. É imperativo verificar se os fatores que causaram as perdas dentárias persistem, e quanto influenciam as decisões de extrair dentes na população jovem e adulta atual. Há que se mudar o modelo de atenção pela inclusão e qualificação da atenção em saúde bucal da população adulta jovem e idosa, sob pena de persistir o modelo de mutilação dentária e a cultura de edentulismo.

Abstract The objective was to analyze and systematize evidence reported in qualitative studies on the reasons and consequences of tooth loss in adults and elderly people in Brazil. A systematic review of the literature on qualitative research methods and a meta synthesis of the results were performed. The study population consisted of adults over 18 years of age and elderly people in Brazil. Searches were performed in the BVS, PubMed, Scopus, Web of Science, BBO, Embase, EBSCO and SciELO databases. The thematic synthesis identified 8 analytical themes regarding reasons for tooth loss and 3 analytical themes regarding consequences of tooth loss. Dental pain, care model, financial situation and desire for prosthetic rehabilitation were determining factors for extractions. There was recognition of negligence in oral care, and the naturalness of tooth loss was linked to old age. Missing teeth caused psychological and physiological impacts. It is imperative to verify whether the factors that cause tooth loss persist, and how much those factors influence decisions to extract teeth among current young and adult populations. It is necessary to change the care model through the inclusion and qualification of oral health care for the young and elderly adult populations; otherwise, the model of dental mutilation and the culture of edentulism will persist.

Prevalence of tooth loss, bleeding on probing and malocclusion as oral disease indicators in Costa Rican male adolescents: a cross sectional study / Prevalencia de la pérdida de piezas dentales, del sangrado al sondeo y la maloclusión como indicadores de enfermedades orales en adolescentes varones costarricenses: un estudio transversal

The evidence to characterize oral health during adolescence in Costa Rica is limited. This lack of adequate research makes it difficult to develop appropriate health policies for this subgroup of the population. This is particularly important because adolescence is the period during which good health habits must take root in order to foster good physical and cognitive development. This study aims to determine the prevalence of tooth loss, bleeding on probing and malocclusion in Costa Rican male adolescents at the ''Colegio Técnico Profesional San Agustín'' (St. Augustine's Technical High School) located in the province of Cartago. Data was collected from 428 male adolescents aged 12-22 years in a cross-sectional study during 2019. Prevalence of tooth loss was calculated as the number of individuals having lost at least one tooth. The average number of teeth lost by individuals was also recorded. The bleeding on probing was an indicator used as a proxy parameter for monitoring periodontal health where the presence of bleeding on probing and calculus was also recorded. Malocclusion was measured using the Dental Aesthetic Index (DAI). The results showed that the prevalence of tooth loss, bleeding on probing and malocclusion was of 19%, 70.0% and 98%, respectively. It was also found that 81% of the participants had all their teeth, 11% had lost 1 tooth, 8% had lost more than one tooth of which 0.5% had lost more than 5 teeth. Considering a general classification of periodontal problems based on bleeding on probing and presence of calculus, the prevalence of periodontal problems increases to 92%. Regarding the DAI, the category identifying a very severe malocclusion was the most prevalent in the sample (88%). It is alarming the high prevalence of tooth loss, bleeding on probing, and malocclusions in a sample of Costa Rican male adolescents, compared to similar studies in other countries. The overarching conclusion of this study is that oral diseases represent an important health problem that urgently need proper public health action.

La evidencia para caracterizar la salud bucal durante la adolescencia en Costa Rica es limitada. Esta falta de investigación adecuada dificulta el desarrollo de políticas de salud convenientes para este subgrupo de la población. Esto es particularmente importante porque la adolescencia es el período durante el cual se deben arraigar buenos hábitos de salud para fomentar un buen desarrollo físico y cognitivo. Este estudio tiene como objetivo determinar la prevalencia de pérdida de piezas dentales, sangrado al sondeo y maloclusión en adolescentes varones costarricenses del Colegio Técnico Profesional San Agustín ubicado en la provincia de Cartago. Se recopilaron datos de 428 adolescentes varones de 12 a 22 años en un estudio transversal durante 2019. La prevalencia de pérdida de piezas dentales se calculó como el número de individuos que habían perdido al menos una pieza dental. También se registró el número promedio de dientes perdidos por individuos. El sangrado al sondeo fue un indicador utilizado como parámetro para el seguimiento de la salud periodontal donde también se registró la presencia de sangrado al sondeo y cálculo dental. La maloclusión se midió utilizando el Índice Estético Dental (DAI, por sus siglas en inglés). Los resultados mostraron que la prevalencia de pérdida de piezas dentales, sangrado al sondeo y maloclusión fue del 19%, 70,0% y 98%, respectivamente. También se encontró que el 81% de los participantes tenían todos sus dientes, el 11% había perdido 1 pieza dental, el 8% había perdido más de una pieza dental, de los cuales el 0,5% había perdido más de 5 piezas dentales. Considerando una clasificación general de problemas periodontales basada en sangrado al sondeo y presencia de cálculo, la prevalencia de problemas periodontales aumenta al 92%. En cuanto al DAI, la categoría que identifica una maloclusión muy severa fue la más prevalente en la muestra (88%). Es alarmante la alta prevalencia de pérdida de piezas dentales, sangrado al sondeo y maloclusiones en una muestra de adolescentes varones costarricenses, en comparación con estudios similares en otros países. La conclusión general de este estudio es que las enfermedades bucodentales representan un importante problema de salud que necesita urgentemente una acción adecuada de salud pública.

Multivariable analysis of tooth loss in subjects with severe periodontitis over 4-year natural progression / 北京大学学报(医学版)

OBJECTIVE@#To evaluate the characteristics of severe periodontitis with various number of tooth loss during 4-year natural progression, and to analyze the factors related to higher rate of tooth loss.@*METHODS@#A total of 217 patients aged 15 to 44 years with severe periodontitis were included, who participated in a 4-year natural progression research. Data obtained from questionnaire survey, clinical examination and radiographic measurement. Tooth loss during 4-year natural progression was evaluated. The baseline periodontal disease related and caries related factors were calculated, including number of teeth with bone loss > 50%, number of missing molars, number of teeth with widened periodontal ligament space (WPDL), number of teeth with periapical lesions and etc. Characteristics of populations with various number of tooth loss and the related factors that affected higher rate of tooth loss were analyzed.@*RESULTS@#In 4 years of natural progression, 103 teeth were lost, and annual tooth loss per person was 0.12±0.38. Nine patients lost 3 or more teeth. Thirty-four patients lost 1 or 2 teeth, and 174 patients were absent of tooth loss. Molars were mostly frequent to lose, and canines presented a minimum loss. The number of teeth with WPDL, with periapical lesions, with intrabony defects, with probing depth (PD)≥7 mm, with PD≥5 mm, with clinical attachment loss≥5 mm, with bone loss > 50% and with bone loss > 65% were positively correlated to number of tooth loss. Results from orderly multivariate Logistic regression showd that the number of teeth with bone loss > 50% OR=1.550), baseline number of molars lost (OR=1.774), number of teeth with WPDL (1 to 2: OR=1.415; ≥3: OR=13.105), number of teeth with periapical lesions (1 to 2: OR=4.393; ≥3: OR=9.526) and number of teeth with caries/residual roots (OR=3.028) were significant risk factors related to higher likelihood of tooth loss and multiple tooth loss.@*CONCLUSION@#In 4 years of natural progression, the number of teeth with bone loss > 50%, baseline number of missing molars, number of teeth with WPDL, baseline number of teeth with periapical lesions and number of teeth with caries/residual roots were significantly related to higher risk of tooth loss and multiple tooth loss among Chinese young and middle-aged patients with severe periodontitis in rural areas.

Oral disorders among older Chileans: prevalence, incidence, and years lived with disability / Prevalência, incidência e anos vividos com incapacidade por doenças bucais no Chile

OBJECTIVE: Prior epidemiological surveys revealed that Chile experiences a high burden of oral diseases. However, no prior study has reported estimates of untreated dental caries, periodontitis, and edentulism over a three-decade period for the country. Using estimates of the Global Burden of Diseases Study (GBD) 2019, the objective of this study is to report the trends of prevalence, incidence, and years-lived with disability (YLDs) due to untreated dental caries, periodontitis, and edentulism in Chilean older adults between 1990 and 2019. METHODS: Estimates of prevalence, incidence, and YLDs due to dental caries, periodontitis, and edentulism were produced for Chile, by age and sex, between 1990 and 2019, using Dismod-MR 2.1. Trends of oral disorders were analyzed using generalized linear regression models applying the Prais-Winsten method. RESULTS: Untreated dental caries and periodontal disease showed an increase in prevalence and YLDs, whereas edentulism prevalence, incidence, and YLDs decreased in all older adults age groups. The incidence of dental caries decreased in the younger groups and increased in the older age groups; while the incidence of periodontal disease increased in the younger and decreased in the older age groups. CONCLUSIONS: Overall, the burden of oral diseases in older Chileans increased between 1990 and 2019. This was particularly relevant for untreated caries and periodontal disease. Future estimates of oral diseases burden in Chile require concerted efforts to produce national health surveys that incorporate oral diseases metrics. These estimates are essential to inform policy formulation, implementation and evaluation. (AU)

OBJETIVO: Pesquisas epidemiológicas anteriores revelaram que o Chile apresenta uma elevada carga de doenças bucais. No entanto, nenhum estudo anterior relatou estimativas de cárie dentária não tratada, periodontite e edentulismo ao longo de um período de três décadas para o país. Usando estimativas do Global Burden of Diseases Study (GBD) 2019, o objetivo deste estudo é relatar as tendências de prevalência, incidência e anos vividos com incapacidade (YLDs) devido a cárie dentária não tratada, periodontite e edentulismo em idosos chilenos entre 1990 e 2019. METODOLOGIA: Estimativas de prevalência, incidência e YLDs devido à cárie dentária, periodontite e edentulismo foram produzidas para o Chile, por idade e sexo, entre 1990 e 2019, usando o Dismod-MR 2.1. Tendências de distúrbios bucais foram analisadas usando modelos de regressão linear generalizada aplicando o método Prais-Winsten. RESULTADOS: A cárie dentária não tratada e a doença periodontal mostraram um aumento na prevalência e nos YLDs, enquanto a prevalência, incidência e YLDs do edentulismo diminuíram em todas as faixas etárias de idosos. A incidência de cárie dentária diminuiu nos grupos mais jovens e aumentou nos grupos etários mais velhos; enquanto a incidência de periodontite aumentou nos grupos mais jovens e diminuiu nos grupos etários mais velhos. CONCLUSÕES: No geral, a carga de doenças bucais em idosos chilenos aumentou entre 1990 e 2019. Isso foi particularmente relevante para cárie não tratada e periodontite. As estimativas futuras da carga de doenças bucais no Chile exigem esforços concentrados para produzir pesquisas nacionais de saúde que incorporem métricas de doenças bucais. Essas estimativas são essenciais para informar a formulação, implementação e avaliação de políticas. (AU)

Impact of social marginalization on oral health-related quality of life in older adults

Abstract The aim of this study was to determine the association between oral health-related quality of life (OHRQoL) and social marginalization in people aged 60 years and older enrolled in social security in Mexico. A cross-sectional and analytical study was carried out in older adults. To assess the OHRQoL, the OHIP-14 instrument was applied, and the degree of social marginalization and sociodemographic characteristics were analyzed. Measures of central tendency and dispersion, simple frequencies and proportions were estimated. Student's t-test was used for comparison of means, and prevalence ratio (PR) and logistic regression were used to assess associations, all with a significance value of 0.05 and 95% confidence intervals. Perceived OHRQoL in the population measured through the OHIP-14 reached an average value of 9.84 ± 8.91, with the highest value in the dimension of physical pain (2.06 ± 1.91). Perceived treatment need was higher among people with social marginality (p = 0.011). The multivariate analysis shows that marginalized people have a lower OHRQoL. Socially marginalized older adults showed a low a better perception of OHRQoL, independent of demographic and clinical factors.

Association between toothbrushing frequency and dental caries and tooth loss in adolescents: a cohort study

Abstract This cohort study assessed the association between toothbrushing frequency and the increment of dental caries and tooth loss in a population-based sample of southern Brazilian adolescents, to investigate whether there is any additional benefit in performing a third daily brushing. At baseline, 1,528 12-year-old schoolchildren attending 42 schools were examined for gingivitis and dental caries, and answered a questionnaire. After a mean period of 2.5 years, 801 schoolchildren were re-examined. Dental caries and tooth loss increment were outcomes of the study. The main predictor variable was toothbrushing frequency (≥3 times/day vs. twice/day or ≤1 time/day). Poisson regression models were used to estimate the risk for caries and tooth loss increment. Incidence risk ratios (IRR) and 95% confidence intervals (CI) were estimated. The final model adjusted for sociodemographic, behavioral, and clinical variables showed that brushing twice/day afforded 40% greater risk (IRR = 1.40; 95%CI: 1.02-1.92) for caries increment than ≥3 times/day. Regarding the tooth loss increment, adolescents who brushed their teeth twice/day had a fourfold greater risk (IRR = 3.92; 95%CI: 1.23-12.49) than those who brushed ≥ 3 times/day. Sex, school type, and gingivitis were found to act as effect modifiers, inasmuch as a third daily brushing presented advantages against tooth loss only for girls, public school attendees, and those with ≥ 50% of bleeding sites. This study suggests that adolescents benefit from a third daily toothbrushing. Increasing brushing frequency to 3 times/day may be a suitable strategy to control dental caries and tooth loss among high-risk adolescents.

Associations between physical activity domains and oral health: an analysis of a Brazilian population-based study

Abstract Physical activity comprises four domains (leisure, transportation, domestic, and work activities) that may be differently associated with oral health. The aim of this study was to assess the association between each physical activity domain and oral health conditions in Brazilian adults. A total of 38,539 participants in the 2019 Brazilian Health Survey aged 30 years or older were analyzed. The outcomes were self-perceived oral health (dichotomous) and self-reported number of missing teeth (counts). The presence, frequency, and time of activity in each domain and their combination were analyzed as main exposures. Odds ratios (OR) and mean ratios (MR) were estimated by fitting multivariable models. Higher leisure time physical activity was the only domain associated with better self-perception of oral health (OR = 1.32; 95%CI 1.26-1.38) and lower tooth loss (MR=0.88; 95%CI 0.86-0.90). Higher levels of work, transportation, and household activities were significantly associated with worse self-perception of oral health, while higher levels of work- and transportation-related physical activities were also associated with greater tooth loss. When the total recommended weekly physical activity time was analyzed, no significant associations were found. Sensitivity analysis suggested that this pattern persists in potential periodontitis-related cases, such as when selecting older age or excluding individuals with no tooth loss. In conclusion, leisure physical activity was the only domain with the potential of reflecting the benefits of physical activity on oral health. The inclusion of other domains can confound this association.

Evaluation of clinical effect of 3D printing-aided autologous tooth transplantation for repairing tooth loss / 西安交通大学学报(医学版)

【Objective】 To evaluate the clinical effect of 3D printing technology in autogenous tooth transplantation for tooth loss. 【Methods】 From September 2017 to August 2021, 169 patients (176 teeth) were selected and analyzed regarding age, gender, recipient site, positioning of the donor tooth, transplantation time, and long-term follow-up. 【Results】 A total of 176 autogenous tooth transplants were completed, consisting of 133 cases of traditional autogenous tooth transplantation and 43 cases of autogenous tooth transplantation with 3D printing technology. The donor tooth separation time for autogenous tooth transplantation with 3D printing technology was significantly less than that for traditional autogenous tooth transplantation (P<0.000 1). A total of nine teeth were removed 3 months after the operation due to loosening(autogenous tooth transplantation failure), among which seven failed in traditional tooth transplantation and two failed in autologous tooth transplantation with 3D printing technology. The success rate of traditional tooth transplantation was 77% and the retention rate was 94.7%. The success rate of tooth transplantation with 3D printing technology was 88%, and the retention rate was 95.3%. 【Conclusion】 3D printed tooth donor model can greatly shorten the time of tooth donor, reduce the damage to the periodontal membrane cells of the transplanted teeth, and improve the success rate of tooth transplantation. It is worthy of broad promotion.

Creencias en salud bucal en personas que asisten a una facultad de odontología. Estudio cualitativo

Objetivo: Explorar las creencias en salud bucal de personas que asisten como pacientes a una facultad de odontología de una universidad privada regional chilena. Metodología: Estudio cualitativo que exploró las creencias acerca de salud bucal de 11 personas que asistían por tratamiento a una universidad privada chilena, a través de entrevistas semi-estructuradas, transcritas verbatim. Se realizó análisis de contenido en Atlas-ti 8.4, construyendo categorías y subcategorías, tanto predeterminadas como emergentes. Se realizó triangulación entre los investigadores. Se contó con la autorización del comité de ética e investigación y se realizó consentimiento informado. Resultados: Se generaron cinco categorías: creencias sobre caries dental, creencias sobre enfermedad periodontal, creencias sobre pérdida dentaria, creencias sobre higiene bucal y origen de las creencias en salud bucal, reflejando creencias en salud variadas, nutridas principalmente de su entorno cercano y no profesional. Conclusión: Las personas que acuden a una facultad de odontología por atención presentan creencias en salud más ajustadas a caries, que a periodontitis y a pérdida dentaria. El origen de las creencias usualmente es la familia y conocidos, más que de profesionales.

Aim: To explore the beliefs in oral health of people who attend a dental school of a private regional Chilean university as patients. Methods: A qualitative study explored the beliefs about oral health of 11 people attending a private Chilean university for treatment, through semi-structured interviews, transcribed verbatim. The content was analyzed in Atlas-ti 8.4, building predetermined and emerging categories and subcategories. Triangulation was carried out among the researchers. The study was authorized by the Ethics and Research Committee and informed consent was obtained. Results: Five categories were generated: beliefs about dental caries, beliefs about periodontal disease, beliefs about tooth loss, beliefs about oral care, and origin of beliefs in oral health. Varied health beliefs were reflected, influenced mainly by their close and non-professional environment. Conclusions: People who attend a dental school for care present health beliefs more related to caries than to periodontitis, oral care, and tooth loss. The origin of the beliefs is usually family and acquaintances, rather than dentists.

Exploration of the motivations in the adherence of patients to periodontal maintenance therapy / Exploración de las motivaciones en la adherencia de los pacientes en la mantención periodontal

Introduction: Although it has been shown that the supportive periodontal therapy (SPT) is essential to maintain the results obtained by periodontal therapy, patient adherence to SPT is not usually satisfactory (4). The objective of this research is to explore the motivations in the adherence to periodontal maintenance of patients treated at Universidad Viña del Mar (UVM) during the year 2020. Material and Methods: A study based on the qualitative paradigm was carried out using a design based on discourse analysis through semi-structured interviews. A sample size of 10 participants was consolidated, by obtaining with them the saturation of data collected and of 4 main dimensions. Each interview was transcribed ad verbatim and later analyzed through the Atlas.ti 9 Software. Results: Four main categories or dimensions were created: Motivations of the patients to produce a change in their oral health; Information that the patients have regarding their oral health; Oral hygiene habits acquired after periodontal treatment; Situations that prevent adherence to periodontal treatment. Conclusion: The main motivations of patients to adhere to supportive periodontal therapy are related to the education and information they acquire in the first phase of periodontal treatment. Observing the changes during treatment, improving oral health, improving aesthetics and functionality, are other important motivations, as well as the patients' fear of losing their teeth and the desire to educate their family.

Introducción: Aunque se ha demostrado que la fase de mantención periodontal (TPS) es esencial para mantener los resultados obtenidos por la terapia periodontal, la adherencia del paciente a la TPS no es, en su mayoría, satisfactoria (4). El objetivo de esta investigación es explorar las motivaciones de los pacientes en la adherencia a la mantención periodontal, atendidos en la Universidad Viña del Mar (UVM), durante el año 2020. Material y Métodos: Se realizó una investigación basada en el paradigma cualitativo por medio de un diseño en base al análisis de discursos a través de entrevistas semiestructuradas. Se consolidó un tamaño muestral de 10 participantes, al obtener con ellos la saturación de datos recolectados y de 4 dimensiones principales, cada entrevista fue transcrita ad verbatim y posteriormente analizadas a través del Software Atlas.ti 9. Resultados: Se generaron cuatro categorías o dimensiones principales: Motivaciones del paciente para generar un cambio en su salud oral, Información que posee el paciente respecto a su salud oral, Hábitos de higiene oral adquiridos posterior al tratamiento periodontal y Situaciones que impiden la adherencia al tratamiento periodontal. Conclusión: Las motivaciones principales que presentan los pacientes para adherirse a la fase de mantención periodontal, están relacionadas con la educación e información que adquieren en la primera fase del tratamiento periodontal. Observar los cambios durante el tratamiento, adquirir salud oral, mejorar la estética y funcionalidad, son otras motivaciones de importancia, así como el miedo que presenta el paciente de perder sus dientes y las ganas de querer educar a su familia.

Prevalence of premature loss of deciduous teeth and its relationship with gender among children from Acapulco, Guerrero: a cross-sectional study / Prevalencia de pérdida prematura de dientes deciduos y su relación con el género en niños de Acapulco, Guerrero: estudio transversal

Abstract Background: Premature loss of deciduous teeth is the exfoliation or extraction before physiological replacement with < 50% or < 75% of the root of the substitute tooth formed or if there is > 1 mm of alveolar bone covering the permanent successor tooth organ. This study aimed to estimate the prevalence of premature tooth loss in children and identify associated factors in a health center in Acapulco, Guerrero. Methods: We conducted a cross-sectional study in which we collected information from 109 clinical records of children examined from January 2019 to August 2021. Sociodemographic data of the children and parents were collected: socioeconomic level, non-pathological personal history, and the history of premature deciduous tooth loss. Multivariate analysis to identify factors associated with premature deciduous tooth loss was performed with CIETmap statistical software. Odds ratio (OR) and 95% confidence interval (CI) were calculated to estimate the strength of the association. Results: The prevalence of premature loss of primary teeth was 40% (43/109). The leading cause was caries (84%, 36/43). The tooth organ with the highest loss occurrence was the lower right second molar (33%, 14/43). Gender was identified as an associated factor, with males having a higher risk of loss (ORa = 2.97; CI95% = 1.33-6.65). Conclusions: Our results were similar to those reported in other studies. Strategies aimed at health promotion directed at parents and children should be reinforced.

Resumen Introducción: Se considera como pérdida prematura de dientes deciduos a la exfoliación o extracción antes del recambio fisiológico con < 50% o < 75% de la raíz del diente sustituto formado, o si existe > 1 mm de hueso alveolar cubriendo al órgano dentario sucesor permanente. El objetivo de este trabajo fue estimar la prevalencia de pérdida prematura dental en niños e identificar factores asociados en un centro de salud de Acapulco, Guerrero. Métodos: Se llevó a cabo un estudio transversal en el que se recopiló información de 109 expedientes clínicos de niños atendidos de enero de 2019 a agosto de 2021. Se recolectaron datos sociodemográficos de los niños y los padres: nivel socioeconómico, antecedentes personales no patológicos y el antecedente de la pérdida prematura del diente deciduo. Se realizó un análisis multivariado para identificar factores asociados con la pérdida prematura de dientes deciduos con el software estadístico CIETmap. Se calcularon la razón de momios (OR) y el intervalo de confianza (IC) del 95% para estimar el grado de la asociación. Resultados: La prevalencia de pérdida prematura de dientes primarios fue del 40% (43/109). La principal causa fue por caries (84%, 36/43). El órgano dentario con más ocurrencia de pérdida fue el segundo molar inferior derecho (33%, 14/43). Se identificó el sexo como factor asociado, y se observó que el sexo masculino presenta mayor riesgo de pérdida (ORa = 2.97; IC95% = 1.33-6.65). Conclusiones: Nuestros resultados fueron similares a lo reportado en otros estudios. Deben reforzarse las estrategias de promoción de la salud dirigidas a los padres de familia y a sus hijos.

Perda dentária e suas consequências psicossociais em adultos e idosos / Tooth loss and its psychosocial consequences in adults and older people / La pérdida de dientes y sus consecuencias psicosociales enadultos y ancianos

Introdução: É notório que a perda dentária é um obstáculo a ser lidado na saúde bucal, sendo ainda considerada um problema de saúde pública no Brasil que gera consequências físicas e psicológicas principalmente para adultos e idosos. Objetivo: Descrever as principais consequências psicossociais ocasionadas pela perda dentária em adultos e idosos. Metodologia: Trata-se de uma revisão integrativa da literatura, em que foram realizadas buscas bibliográficas eletrônicas com intervalo de tempo de publicação de seis anos (2016 -2022) nas bases de dados Biblioteca Virtual em Saúde (BVS) e Scientific Electronic Library Online (SciELO). Foram usados os descritores Perda de Dente, Saúde Bucal, Impacto Psicossocial, Adulto e Idoso com o auxílio do operador booleano "and", sendo contemplados artigos em português e inglês no qual o título, o resumo e a leitura na íntegra se relacionassem com o tema, e excluídas publicações do tipo monografias, dissertações, teses, capítulos de livros, livros na íntegra e artigos que não abordaram o tema de estudo. Resultados: Foram utilizados 14 artigos no total para compor o referencial teórico da revisão, sendo que todas essas publicações trouxeram informações relevantes quando se associa a perda dentária com o impacto psicossocial no público alvo. Situações como a vergonha ao sorrir ou falar em público e o comprometimento da fala geram um importante impacto na qualidade de vida dessas pessoas, despertando nelas um sentimento de inferioridade. Conclusão: A perda dentária abala a qualidade de vida das pessoas. Fatores psicológicos como a timidez, a vergonha e alteração de rotinas influenciam na vida social de adultos e idosos (AU).

Use and need of dental prosthesis among community dwelling elderly: a cross-sectional population-based study / Uso e necessidade de próteses dentárias em idosos domiciliados: um estudo transversal de base populacional

Abstract Background By the use of complete or partial dental prosthesis, function, esthetics, and phonetics are reestablished. Few population-based studies are available in the literature using an older adult population. Objective Evaluate the use of and need for dental prostheses and their associated factors. Method This study included a random sample of 287 elderly, in the city of Cruz Alta, Brazil. Use of and need for dental prostheses were the main outcomes, and two analytical models were constructed. Subgroup analyses were performed for individuals using fixed partial denture (FPD) and removable (partial and/or complete) dental prosthesis (RDP). Results Use of and need for dental prosthesis were identified in 83.6% (n=240) and 42.5% (n=122) of the elderly, respectively. Women presented a significantly higher prevalence ratio (PR) for use of dental prostheses (PR=1.15; 95%IC:1.02-1.28) and lower need (PR=0.70; 95%IC:0.54-0.91). No statistically significant difference was demonstrated for the use of FPD regarding the sex. Higher education level was associated with lower use of prostheses (PR=0.73; 95%IC:0.58-0.91) when compared to lower level of education. Medium level of education showed a significantly lower need for dental prostheses (PR=0.61 - 95%IC:0.39-0.94). Those that did not consume alcohol presented with a significantly lower use of FPD and RDP (PR=0.46; 95%IC:0.23-0.93 and 0.90;0.81-0.99, respectively). Conclusion The use of and need for dental prostheses were associated with sex, level of education, and behavioral factors.

Resumo Introdução Pelo uso de próteses dentárias completas ou parciais, função, estética e fonética são reestabelecidas. Poucos estudos de base população estão disponíveis na literatura utilizando a população idosa. Objetivo Avaliar o uso e a necessidade de prótese dentária, bem como seus fatores associados. Método Esse estudo incluiu uma amostra randômica de 287 idosos da cidade de Cruz Alta, no Brasil. Uso e necessidade de prótese dentária foram os desfechos primários, e dois modelos analíticos foram construídos. No uso de prótese dentária, análises de subgrupos foram realizadas para Prótese Parcial Fixa (PPF) e Prótese Removível (parcial e/ou completa) (PR). Resultados Uso e necessidade de prótese dentária foram detectados em 83,6% (n=240) e 42,5% (n=122) dos idosos, respectivamente. Mulheres apresentaram significativa maior Razão de Prevalência (RP) para o uso de prótese dentária (RP:1,15; IC95%:1,02-1,28) e menor necessidade (RP:0,70; IC95%:0,54-0,91). Nenhuma associação significativa foi encontrada para o uso de PPF em relação aos gêneros. Alto nível educacional esteve associado ao menor uso de prótese (RP:0,73; IC95%:0,58-0,91), quando comparado com escolaridade baixa. Escolaridade média mostrou significativa menor necessidade de prótese dentária (RP:0,61 - IC95%:0,39-0,94). Aqueles que não utilizam álcool apresentaram um menor uso de PPF e PR (RP:0,46; IC95%:0,23-0,93 e 0,90;0,81-0,99, respectivamente). Conclusão Uso e necessidade de prótese dentária estão associados ao gênero, nível educacional e fatores comportamentais.

Nasal Wall Oriented Implants for All-on-4 Fix-Detachable Maxillary Reconstruction / Implantes nasales orientados a la pared para una reconstrucción maxilar desmontable fija All-on-4

Abstract Immediate loading of full-arch prostheses on dental implants in the upper arch is challenging, as the bone is of low quality and obtaining sufficient torque may be difficult. The purpose of this case report is to describe the rehabilitation of a full- arch by means of placement of four internal tapered connection tilted implants and immediate loading. A 65-year-old man sought dental care with a partially edentulous upper arch. The teeth presented mobility and were extracted. In a second step, two conventional-length implants were placed in the anterior region and two tilted and nasal wall-directed extra-long implants in the posterior region. The insertion torques of 60 N.cm allowed the installation of an immediate prosthesis (hybrid). The clinical case report suggests that the placement of tilted and extra-long implants in the paranasal bone and immediate loading may be a viable option for rehabilitation of the edentulous upper arch.

Resumen La carga inmediata de prótesis de arco completo en implantes dentales en el arco superior es un desafío, ya que el hueso es de baja calidad y puede ser difícil obtener un par suficiente. El propósito de este reporte de un caso es describir la rehabilitación de un arco completo mediante la colocación de cuatro implantes inclinados de conexión cónica interna y carga inmediata. Un hombre de 65 años buscó atención dental con un arco superior parcial sin dientes. Los dientes presentaron movilidad y fueron extraídos. En un segundo paso, se colocaron dos implantes de longitud convencional en la región anterior y dos implantes extralargos inclinados y dirigidos a la pared nasal en la región posterior. Los pares de inserción de 60 N.cm permitieron la instalación de una prótesis inmediata (híbrida). El informe del caso clínico sugiere que la colocación de implantes inclinados y extralargos en el hueso paranasal y la carga inmediata pueden ser una opción viable para la rehabilitación del arco superior desdentado.

Tooth Loss and Oral Health-Related Quality of Life among Adult Dental Patients: A Cross-Sectional Study

Background: Oral diseases seriously impair the quality of life (QoL) in a large number of individuals and they may affect various aspects of life. Aim: To determine the relationship between tooth loss and oral health?related quality of life (OHRQoL) among adult dental patients. Study Setting and Design: A cross?sectional study was carried out among 296 adult dental patients aged 35–44 years attending Department of Oral Medicine and Radiology of Panineeya Institute of Dental Sciences and Hospital, Hyderabad, India. Materials and Methods: Oral Health Impact Profile?14 (OHIP?14) was used to assess OHRQoL. Dentition status and periodontal status according to WHO criteria 2013 and position, number of teeth lost by Batista et al. (2014) tooth loss classification were assessed. Statistical Analysis: Mann–Whitney U test and analysis of variance were used to find prevalence and severity of OHIP?14 with tooth loss and logistic regression analysis to evaluate the association between OHIP?14 prevalence and severity based on variables. Results: Except for the subjects with history of previous dental visit, variables such as gender and reason for dental visit showed significant difference (P ? 0.05) with tooth loss. Males subjects, who visited dentist with a history of pain, presence of periodontal disease and tooth loss up to 12 teeth (score 3) emerged as significant predictors for OHIP?14 prevalence (OR = 6.7, OR = 1.13, OR = 3.31). Conclusion: The study strongly evidenced that number and position of tooth loss had negative impacts on OHRQoL

Number of teeth lost on diet quality and glycemic control in patients with type 2 diabetes mellitus

ABSTRACT Objectives: To describe the oral health profile and evaluate the impact of tooth loss on diet quality and glycemic control among 66 patients with type 2 diabetes (T2DM) treated in an endocrinology outpatient clinic at a teaching hospital. Materials and methods: Questionnaires about diabetes self-care (SDSCA), masticatory ability, diet quality, anxiety level about dental treatment, and oral health were applied. Laboratory tests were retrieved from medical records or newly collected samples. Results: The presence of fewer than 21 teeth was associated with an unsatisfactory self-perceived masticatory ability (r = 0.44; p = 0.007). Most participants reported not having received guidance on oral health from their endocrinologists (81.8%) and having had the last visit to the dentist 2 years or more before the study (36.8%). The mean HbA1c level in the group with fewer than 21 teeth was comparable to that in the group with functional dentition (8.9 ± 1.5 and 8.7 ± 1.6%, respectively; p = 0.60). Conclusion: Adults with T2DM have a high prevalence of tooth loss and lack of information about oral hygiene care. Our results reinforce the need for more effective communication between medical and dental care teams.
