Minimal intervention dentistry: What is its clinical application and effectiveness in different continents? - A scoping review.

The aim of minimal intervention dentistry (MID) is to maximize the preservation of dental tissues through the use of modern and effective techniques and procedures. The central objective of MID is to increase the functional life of dental elements and, consequently, the quality of life of the population. The present study aimed to analyze and map the diffusion and clinical application of MID in different continents around the world. To perform this scoping review, the PRISMA checklist was used, adopting the following: population - dentists; concept - effectiveness of MID; and context - continents. The following databases were used: PubMed, European Archives of Paediatric Dentistry, Scientific Electronic Library, Latin Literature American and Caribbean Association in Health Sciences, and SCOPUS. The following keywords were used in the searches: "pediatric dentistry," "atraumatic restorative treatment," "dental caries," "child health," and "glass ionomer cements" using "and" and "or" combined with "minimal intervention dentistry." Studies published before 2010 as well as theses, dissertations, opinion articles, editorials, and guidelines, were excluded from the study. A total of 160 articles were obtained, and 17 articles were screened and selected for full reading. The analysis of the studies reveals the disparity in the use of minimal intervention techniques among continents due to a lack of knowledge of these techniques or lack of confidence in changing professional approaches, thus emphasizing the need for the dissemination and teaching of MID.

Creches são ambientes saudáveis quando se trata de saúde bucal? / Are day care centers healthy environments, when it comes to oral health? / ¿Son saludables los jardines de infancia en lo que respecta a la salud bucal?

Creches são consideradas ambientes saudáveis, pois, para além de cumprir uma missão de educação, exercem influência em cuidados básicos de saúde, responsabilizando-se pela integridade física e emocional da criança, bem como orientando hábitos de higiene, alimentação e socialização interpessoal. Neste contexto, o objetivo deste estudo foi avaliar ambientes de creches, compreendendo melhor os fatores de risco presentes e os padrões de comportamento ensinados, assim como sua associação com cárie dentária, traumatismo dentário e presença de biofilme. Trata-se de estudo transversal com utilização da Infant/Toddler Environment Rating Scale Revised (ITERS-R), escala de avaliação de ambientes, conduzido em dois municípios do interior do estado do Rio de Janeiro, em creches públicas e particulares. Para avaliação das lesões de cárie, seguiu-se o critério do Sistema Internacional de Detecção e Avaliação de Cárie (ICDAS ­ International Caries Detection and Assessment System); para a presença de biofilme, o critério de Alaluusua e Malmivirta; e o critério descrito por O'Brien para lesões traumáticas. A associação entre ambiente e desfechos foi verificada através da comparação de médias para as variáveis numéricas, via teste t de Student e, para variáveis categóricas binárias, empregou-se a regressão logística. Foi verificada uma baixa qualidade dos ambientes das creches em relação à saúde bucal, ficando os escores médios de ambiente no valor mais baixo da escala (entre 1,2 e 1,4), e houve associação estatisticamente significante entre ambientes e cárie (RC: 0,51; IC: 0,29-0,88) e com biofilme (RC: 0,27; IC: 0,17-0,42). Conclui-se que existe uma inadequação do ambiente das creches que não contribui para a construção de conhecimentos relativos à educação para saúde bucal, que se associa com desfechos de saúde bucal. Pode-se, assim, considerar creches como ambientes não saudáveis em relação à saúde bucal.

Child Day Care Centers are considered healthy environments since, beyond the educational role, they still influence basic health care, taking responsibility for the physical and emotional integrity of the child, as well as guiding hygiene habits, feeding habits, and interpersonal socialization. Objectives: In this context, this study aimed to evaluate daycare environments, better understanding the health determinants present and the behavior patterns taught, as well as their association with dental caries, dental trauma, and the presence of biofilm. This is a cross-sectional study using the Infant/Toddler Environment Rating Scale Revised (ITERS-R) for assessing environments, carried out in two municipalities in the interior of the state of Rio de Janeiro, in public and private day care centers. To evaluate caries lesions, the International Caries Detection and Assessment System (ICDAS) criterion was followed; for the presence of biofilm, the Alaluusua and Malmivirta criteria; and for traumatic injuries, the criterion described by O'Brien. The association between environment and outcomes was verified by comparing means for numerical variables, via Student's t-test and, for binary categorical variables, logistic regression was used. A low quality of day care centers regarding oral health was verified, with the average environment scores at the lowest value of the scale (between 1.2 and 1.4), and there was a statistically significant association between environments and caries (RC: 0.51; CI: 0.29-0.88) and with biofilm (RC: 0.27; CI: 0.17-0.42). In conclusion, there is an inadequacy of the day care environment that does not contribute to the construction of knowledge related to oral health education, which is associated with oral health outcomes. Therefore, day cares can be considered unhealthy environments regarding oral health.

Los jardines de infancia se consideran un ambiente saludable porque, además de cumplir una misión educativa, influyen en los cuidados básicos de la salud, se responsabilizan de la integridad física y emocional del niño, y orientan los hábitos de higiene, alimentación y socialización interpersonal. Por tanto, este estudio tuvo por objetivo evaluar ambientes de jardines de infancia para comprender mejor los factores de riesgo presentes y padrones de comportamiento enseñados, así como su asociación con la caries dental, traumatismo dental y presencia de biopelícula. Este es un estudio transversal con utilización de escala Infant/Toddler Environment Rating Scale Revised (ITERS-R), la evaluación de ambientes en guarderías públicas y particulares en dos municipios del estado de Río de Janeiro. Para la evaluación de las lesiones de caries, se siguieron los criterios del International Caries Detection and Assessment System (ICDAS); para una presencia de biopelícula se utilizó el criterio de Alaluusua y Malmivirta, y el descrito por O'Brien para lesiones traumáticas. La asociación entre el ambiente y los resultados se observó por medio de la comparación de medias para las variables numéricas, mediante la prueba t de Student, y para las variables categóricas binarias, se utilizó la Regresión Logística. Se constató una baja calidad de los ambientes con relación a la salud bucal, con puntajes promedio de ambiente en el valor más bajo de la escala (entre 1,2 y 1,4) y hubo asociación estadísticamente significativa entre ambientes y caries (OR: 0,51; IC: 0,29-0,88) y con biopelícula (OR 0,27; IC: 0,17-0,42). Se concluye que las guarderías son inadecuadas, porque no contribuyen a la construcción de conocimientos relacionados con la educación en salud bucal y esto se asocia a resultados de salud oral. Se puede, de esa forma, considerarlos ambientes no saludables relacionados a la salud bucal.

Dental procedures cause stress in children with cerebral palsy?

BACKGROUND: To evaluate the level of stress during dental care in children and preadolescents with cerebral palsy through biological and psychological parameters. MATERIAL AND METHODS: A total of 38 children aged 7 to 12 years were divided into two groups: one with 18 children with cerebral palsy and the other with 20 healthy children (control group). Saliva was noninvasively collected before and after dental care to analyze salivary biomarkers. The Frankl Behavior Scale and the Facial Image Scale were applied. RESULTS: After the dental procedure, cortisol levels were significantly higher (p = 0.02) in the cerebral palsy group than in the control group. Salivary alpha-amylase was not significantly different between groups. Regarding psychological parameters, anxiety was significantly higher (p = 0.00012) in the cerebral palsy group than in the control group. CONCLUSIONS: There was a change in physiological parameters (salivary cortisol and salivary alpha-amylase) and in psychological parameters (Frankl Behavioral Scale and Facial Image Scale) in patients with cerebral palsy, who exhibited higher stress and anxiety levels than did children without cerebral palsy. Key words:Ortisol, physiological stress, dental care, cerebral palsy, dental treatment anxiety.

It is noted that from 2018 onwards, the works presented better methodological quality. Moreover, most of the studies showed a certainty of high scientific evidence, determined by using the modified GRADE system and a low risk of bias determined by using the ROBIS tool. Conclusion:The systematic reviews and meta-analyses included in this study presented difficulties in the methodological structuring process, attributing, on average, a certainty of high scientific evidence to GRADE, as well as a low risk of bias determined by ROBIS.

The influence of television on the food habits of schoolchildren and its association with dental caries.

OBJECTIVES: The consumption of food with a high-sugar content is encouraged by the food industry through television (TV) aimed at children and may be associated with dental caries. This study aims to evaluate the influence of TV on the food habits of schoolchildren aged years and its association with dental caries. MATERIAL AND METHODS: This was an observational, epidemiological, and cross-sectional study. Five neighborhoods of Belem District were selected, and then two schools from each neighborhood were drawn (one private and one public). All sixth and seventh grade students were selected. Data were extracted from questionnaires completed by schoolchildren and their parents and the decayed, missing, and filled teeth (DMFT/dmft) indices of the schoolchildren. The indices were carried out by three examiners previously calibrated (κ > .80). Logistic regression analysis was performed to investigate the association of variables of study with consumption of cariogenic foods and occurrence of dental caries. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. RESULTS: Schoolchildren who watched TV for >90 min were more likely to consume cariogenic foods (OR = 2.38; 95% CI [1.57, 3.60]) and have a DMFT + dmft >1 (OR = 2.10; 95% CI [1.37, 3.26]). Those who consumed cariogenic foods while watching TV were more likely to have DMFT + dmft >1 (OR = 14.75; 95% CI [8.24, 6.40]). Parents who bought foods they saw on TV contributed to a higher consumption of cariogenic foods (OR = 3.29; 95% CI [2.07, 5.24]) and DMFT + dmft >1 (OR = 3.93; 95% CI [2.09, 7.37]) among their children. CONCLUSIONS: TV can influence the eating habits of schoolchildren aged 10 to 12 and the food purchases of their parents, stimulating the consumption of cariogenic foods and contributing to the development of dental caries.

Association between clinical manifestations of sickle cell anemia in children and the occurrence of dental caries: a cross-sectional study / Associação entre manifestações clínicas da anemia falciforme em crianças e a ocorrência de cárie dentária: um estudo de corte transversal

Objective: The aim of this study was to determine the association between clinical manifestations of sickle cell anemia (including hospitalization and pain crisis) and dental caries in children in Bahia. Material and Methods: The study design was crosssectional, and the population included children aged from 6 to 96 months from August 2007 to July 2008 (N = 686). Interviews were performed to identify the sociodemographic profiles of the participants, and oral examinations were conducted by three examiners who were previously trained and calibrated to identify the presence of dental caries according to World Health Organization (WHO) criteria. Logistic regression analysis was performed for confirmatory analysis and estimation of confidence intervals (CIs). Results: The results showed that pain crises and hospitalizations were positively associated with caries (crude odds ratio (OR) = 2.11 and adjusted OR = 1.24; crude OR = 2.50 and adjusted OR = 1.46, respectively), but these associations were not statistically significant. Conclusion: The severity of the sickle cell condition alone was not sufficient to aggravate the prevalence of caries; thus, there are no major differences in caries prevalence between children with and without sickle cell disease. (AU)

O objetivo deste estudo foi determinar a associação entre as manifestações clínicas da anemia falciforme (incluindo hospitalização e crise de dor) e cárie dentária em crianças na Bahia. Material e Métodos: O desenho do estudo foi transversal e a população incluiu crianças de 6 a 96 meses de agosto de 2007 a julho de 2008 (N = 686). Foram realizadas entrevistas para identificar os perfis sociodemográficos dos participantes, e os exames bucais foram realizados por três examinadores previamente treinados e calibrados para identificar a presença de cárie dentária de acordo com os critérios da Organização Mundial da Saúde (OMS). A análise de regressão logística foi realizada para análise confirmatória e estimativa de intervalos de confiança (IC). Resultados: Os resultados mostraram que as crises de dor e hospitalizações foram positivamente associadas à cárie (razão de chances bruta (OR) = 2,11 e OR ajustado = 1,24; OR bruto = 2,50 e OR ajustado = 1,46, respectivamente), mas essas associações não foram estatisticamente significantes. Conclusão: A gravidade da doença falciforme isoladamente não foi suficiente para agravar a prevalência de cárie; assim, não há grandes diferenças na prevalência de cárie entre crianças com e sem doença falciforme.(AU)

Factors associated with feeding practices among Brazilian children aged 12 to 23 months old / Fatores associados à prática alimentar de crianças brasileiras de 12 a 23 meses de vida

Abstract Objectives: a quantitative analytical cross-sectional study aimed to identify demographic characteristics to access health services and housing conditions in relation to inadequate feeding practices among Brazilian children from 12 to 23 months of age. Methods: the analysis of the feeding practices (consumption of recommended food groups) of 2541 Brazilian children (aged 12-23 months old) was performed using data from the Pesquisa Nacional de Saúde 2013 (National Health Survey). Descriptive and multivariate statistics used the Decision Tree Analysis based on CHAID (Chi-squared Automatic Interaction Detector) algorithm, as well as hierarchically adjusted Poisson regression analyses were performed. The variables were entered in a hierarchical model at distal (demographic), intermediate (access to health) and proximal (housing conditions) levels. Results: the results showed a high prevalence of sugar consumption (85.5%; CI95%=83.7-87.2) and highlighted inadequate feeding practices among non-white children (p=0.001), resident in the North (p<0.001) and Northeast (p=0.010) of Brazil and in towns in the countryside (p<0.001) presented feeding practices that were not recommended for consumption in the food groups. Conclusions: non-white children, who lived in the North and Northeast regions of Brazil and in the countryside, which are known to be more socioeconomically vulnerable, were more likely to experience inadequate feeding practices.

Resumo Objetivos: estudo transversal analítico, de natureza quantitativa buscou identificar características demográficas, de acesso aos serviços de saúde e de condições de moradia relacionadas à prática alimentar de crianças brasileiras de 12 a 23 meses de vida. Métodos: a partir dos dados da Pesquisa Nacional de Saúde 2013, as práticas alimentares de 2541 crianças brasileiras de 12 a 23 meses, foram analisadas quanto à recomendação de consumo dos grupos alimentares. A análise das características associadas às práticas alimentares foi realizada pela árvore de decisão usando o algoritmo CHAID (Chi-squared Automatic Interaction Detector) e análise de regressão de Poisson ajustada hierarquicamente. As variáveis foram inseridas em modelo hierárquico em níveis distal (demográficas), intermediário (acesso à saúde) e proximal (condições de moradia). Resultados: verificou-se uma alta prevalência no consumo de açúcar (85,5%; IC95%=83,7-87,2) e que crianças que não eram da cor branca (p=0,001), e residiam nas regiões Norte (p<0,001) e Nordeste (p=0,010) do país e em cidades do interior (p<0,001) apresentaram práticas alimentares que não atingem a recomendação de consumo dos distintos grupos alimentares. Conclusão: crianças que não eram da cor branca, residentes no Norte/Nordeste e no interior, áreas de maior vulnerabilidade do país, foram mais propensas à práticas alimentares inadequadas. Medidas para melhorar tais práticas devem abordar as desigualdades socioeconómicas e intervenções de promoção à saúde.

Oral Anomalies In Newborns: An Observational Cross-Sectional Study.

Purpose: To determine the prevalence of oral anomalies in newborns and the influence of maternal and neonatal factors on the development of these anomalies.
Methods: Four hundred newborns were included in the study conducted at the Hospital and Maternity Dom Orione (HMDO) in the city of Araguaína, Tocantins, Brazil. After collecting demographic data and information about the newborns from the medical records, an oral examination was performed by a single examiner.
Results: The prevalence of oral anomalies was 50 percent. Cysts of the oral cavity were the most prevalent anomalies (43 percent), with palatine cysts (26 percent) and alveolar cysts (23 percent) being the most common. Ankyloglossia was present in nine percent of newborns, and congenital eruption cysts and neonatal teeth were present in 0.5 percent and 0.2 percent, respectively. No statistically significant correlation was observed between the prevalence of palatine cysts, alveolar cysts, or ankyloglossia and maternal or neo-natal factors.
Conclusion: Oral anomalies in newborns are not uncommon, making essential the presence of a dentist, especially a pediatric dentist, in the multidisciplinary team of hospitals and maternal wards.

Avaliação do perfil e satisfação de adolescentes com o tratamento endodôntico realizado na unidade de referência do município de Camaçari - BA / Evaluation of the profile and satisfaction of adolescents with endodontic treatment performed at the reference unit of the city of Camaçari - BA

Objetivo: avaliar o perfil do usuário e o nível de satisfação associado ao tratamento endodôntico de pacientes atendidos no CEO de Camaçari-BA. Material e métodos: o desenho de estudo foi de corte transversal, tendo como população os usuários de 12 a 20 anos que demandaram o serviço durante o período de dezembro de 2017 a novembro de 2018 (n=45). Foram realizadas entrevistas para identificação de variáveis sóciodemográficas, além da avaliação da satisfação por um questionário validado (QASSaB). Realizou-se a análise estatística dos dados, registrando a média e respectivo desvio-padrão para as variáveis contínuas, frequência absoluta e relativa para variáveis categoriais e teste qui-quadrado para avaliação de possíveis associações entre elas. Resultados: os participantes tiveram média de idade de 16,8 anos (±2,067), com renda familiar média de R$ 972,00 e maioria do sexo feminino (55,6%). Dos dentes tratados 31,1% foram molares, 31,1% pré-molares e 37,8% caninos e incisivos, sendo que maior parte pertenciam ao arco superior (75,6%). Os resultados mostraram que no geral houve um bom grau de satisfação do usuário com o atendimento, porém foram verificados pontos de menor satisfação, como foi o caso da acessibilidade e resolutividade. Na dimensão eficácia os pacientes atendidos por especialistas relataram ter menos incômodo durante o tratamento, porém não foi estatisticamente significante (p=0,391). Conclusões: este tipo de estudo tem grande valia já que se podem estabelecer comparativos e realizar planejamentos adequados a partir da identificação dos pontos de necessidade de intervenção.

Objective: to evaluate the user profile and level of satisfaction of patients associated with the endodontic treatment of patients treated at the CEO of Camaçari-BA. Material and methods: The study design was cross-sectional, with a population varying from 12 to 20 year old who demanded the service during the period from December 2017 to November 2018 (n=45). Interviews were carried out to identify socio-demographic variables, as well as satisfaction assessment by a validated questionnaire (QASSaB). Statistical analysis of the data was performed, recording the mean and respective standard deviation for the continuous variables and chi-square test (χ2) for the evaluation of possible associations between categorical variables. Results: participants presented a mean age of 16.8 years (±2.067), with an average family income of R$ 972.00 and majority of females (55.6%). Among the treated teeth, 31.1% were molars, 31.1% premolars and 37.8% canines and incisors, most of which belonged to the upper arch (75.6%). The results showed that in general there was a good degree of user satisfaction with the service, but points of less satisfaction were verified, as was the case of accessibility and resolution. In terms of efficacy, patients attended by specialists reported less discomfort during treatment, but this data was not statistically significant (p=0.391). Conclusions: this study has great value since it is possible to establish comparatives and to carry out adequate planning from the identification of the need points of intervention

Normative need for orthodontic treatment and perception of the need for such treatment among Brazilian adolescents.

OBJECTIVE:: The aim of the present study was to evaluate the normative need for orthodontic treatment and the perception of such need among students aged 11-14 years. METHODS:: A cross-sectional study was conducted with a sample of 346 students, randomly selected from public and private schools. The Dental Aesthetic Index (DAI) was used to evaluate the normative need for orthodontic treatment (NNOT). The perceived need for treatment among students was assessed by a previously validated questionnaire. Data was analyzed by Pearson's Chi-squared test (α = 5%). RESULTS:: The prevalence of malocclusion and NNOT was 65.6%. Of the sample, 73.7% felt they needed treatment, 66.2% wanted orthodontic treatment and 62.7% were satisfied with their dental aesthetics. A statistically significant association was observed between NNOT and the perception of the need for treatment among the students (p < 0.001). CONCLUSION:: The present study demonstrated a high prevalence of malocclusion, which was reflected in the high normative need for orthodontic treatment. The opinion of patients regarding their expectations of orthodontic treatment should be valued. The students perceived a need for orthodontic treatment.

Assessing different patterns of laser welding with NickelChromium (Ni-Cr) alloy for structures applicable to fixed prosthesis / Avaliação de diferentes parâmetros de soldagem a laser em liga de Níquel-Cromo levando em consideração estruturas aplicáveis à Prótese Fixa

Objectives: Among all desired requirements to dental prosthesis, marginal adaptation and passive fit are the most important. In some cases, in order to achieve these goals, it is necessary to cut and weld the teeth / implant-supported framework. Nowadays, the laser welding process shows a great advantage in comparison to other methods. The aim of this study was to evaluate the optimal laser welds point that is more appropriate to Ni-Cr prosthetic framework. Material and methods: A total of 60 specimens of Ni-Cr (35 mm x 4 mm) were designed and welded using a Nd:YAG laser device model EV 900. They were fixed in a metal piece 0.27 mm between the ends to be welded. All specimens were welded with 21 laser pulses diametrically opposed (frequency of 1.0Hz, load time 3.0 ms and 0.5 mm of diameter pulse). They were divided into three groups according to the electric current of the laser weld: A ­ 180A; B ­ 200A; C ­ 220A; and D- control group with no welding process. To determinate the flexural mechanic strength, all specimens were submitted to a three-point bending test. Results: The results obtained were: Group A = 553,76 Mpa; B = 751,02 Mpa and C = 802.13 Mpa. The control group was 1040.9 Mpa. ANOVA and Tukey's test were performed and statistical significance differences were observed between group A and B as well as between group A and C. However, no significant difference was observed between B and C. The group D (no welding process), significant difference was observed between A, B and C.

Objetivos: Entre os requisitos de uma prótese fixa estão a adaptação marginal e seu assentamento passivo. Em alguns casos, para alcançarmos estes requisitos, devemos realizar o seccionamento e soldagem da infraestrutura metálica. Os procedimentos de soldagem a laser apresentam várias vantagens em relação aos outros processos de união. O objetivo deste trabalho foi avaliar os parâmetros ideais para soldagens a laser em de infraestruturas protéticas em Ni-Cr. Material e métodos: Foram confeccionados 60 infraestruturas (35 mm X 4,0 mm), que foram soldadas utilizando um aparelho de solda a laser Nd:YAG modelo EV 900. As amostras foram fixadas em uma peça metálica, mantendo padronizada uma distância de 0,27 mm entre as extremidades a serem unidas. Todas as amostras foram soldadas com 21 pulsos diametralmente opostos (frequência de 1,0 Hz, tempo de carga de 3,0 ms e 0,5 mm de diâmetro do pulso) e foram divididas em três grupos experimentais, alterando-se a intensidade da corrente elétrica da solda a laser: A) 180 A; B) 200 A; C) 220 A e D) grupo controle -sem processo de soldagem. Para se determinar a resistência mecânica flexural, todas as amostras foram submetidas ao teste de flexão de três pontos em máquina de teste universal. Resultados: Os resultados médios obtidos foram: grupo A) 553 Mpa, B) 751,0 Mpa, C) 802,1 Mpa e para a amostra controle foi de 1040,9 Mpa.

Antimicrobial Activity of Photodynamic Therapy Against Enterococcus faecalis Before and After Reciprocating Instrumentation in Permanent Molars.

OBJECTIVE: The present study sought to evaluate the antimicrobial activity against Enterococcus faecalis of photodynamic therapy applied before and after reciprocating instrumentation of permanent molars. BACKGROUND: Apical extrusion of debris can cause flare-ups due to introduction of bacteria into the periapical tissues. METHODS: Eighteen mesial roots from permanent mandibular molars were selected. The crowns were removed to obtain a standard root length of 15 mm. The included mesial roots had an angulation of 10°-40° and canals with independent foramina. The orifice of each mesiolingual canal was sealed with light-curing resin, and the working length was established visually, 1 mm short of the apical foramen. The roots were rendered impermeable and sterilized, and the mesiobuccal canals were contaminated with a standard strain of E. faecalis for 21 days. Specimens were randomly divided into three groups (n = 6): G1, photodynamic therapy performed before instrumentation and irrigation with 0.9% NaCl (saline) solution; G2, photodynamic therapy performed after instrumentation and irrigation with 0.9% NaCl; and G3 (control), instrumentation and irrigation with 2.5% NaOCl (sodium hypochlorite) solution. Canals were shaped with a WaveOne primary file (25.08) and irrigated with 0.9% NaCl. E. faecalis samples were collected before and after each procedure, and the results were analyzed using descriptive statistics and the Kruskal-Wallis and Wilcoxon tests. RESULTS: Significant reductions in E. faecalis were observed when photodynamic therapy was performed before and after instrumentation of the root canal system (p < 0.05). Reciprocating instrumentation significantly reduced E. faecalis colonies in experimentally contaminated root canal systems (p < 0.05). CONCLUSIONS: Photodynamic therapy was effective in removing E. faecalis from the root canal system, whether performed before or after reciprocating instrumentation.

Comparative Analysis of Protaper and Waveone Systems to Reduce Enterococcus Faecalis from Root Canal System in Primary Molars--An in Vitro Study.

OBJECTIVE: To assess, in vitro, the ability of the ProTaper(™) and WaveOne(™) systems to reduce Enterococcus faecalis contamination in primary molars. STUDY DESIGN: Sixty roots of primary molars were contaminated with E. faecalis. Roots were randomly allocated to one of four groups (n=20): ProTaper(™), WaveOne(™), control A, or control B. The files used were S1 and S2/F1 and F2 (ProTaper(™) system) and 25.08 (WaveOne(™) system). In control group A, the root canal was left uninstrumented, whereas in control group B, the root canal was irrigated with NaCl 0.9%. E. faecalis was sampled from the root canal system before and after instrumentation and the Wilcoxon test and Mann-Whitney U were used. RESULTS: There were no differences in E. faecalis counts between pre-instrumentation counts in the ProTaper™ and WaveOne(™) (p>0.05). The ProTaper(™) system led to an 89.36% reduction in E. faecalis burden, versus 78.10% with the WaveOne(™) system (p>0.05). Instrumentation time was shorter with WaveOne(™) (p<0.0001). CONCLUSIONS: The ProTaper(™) and WaveOne™ systems were equally effective in reducing Enterococcus faecalis in primary molars. The WaveOne(™) system was associated with shorter instrumentation time.

Relação da oclusão dentária na presença de curvaturas não fisiológicas da coluna vertebral / Relationship between dental occlusion and non-physiological curvature of the vertebral column

O objetivo desse trabalho foi verificar a relação entre a oclusão dentária e as curvaturas não fisiológicas da coluna vertebral. A amostra foi composta por 88 indivíduos com diagnóstico médico e radiográfico confirmado de desvio postural, atendidos em Ambulatório Médico-Odontológico noEstado de João Pessoa-PB. Para a coleta de dados realizou-se um exame clínico da oclusão dentária em relação vertical de normalidade, mordida em topo, aberta e profunda. Posteriormente a relação transversal de oclusão foi qualificada em normalidade, desvio de linha média, apinhamento inferior e/ou superior e mordida cruzada posterior uni ou bilateral. A relação ântero-posterior foi determinada conforme classificação de Angle em: normalidade, classe I, II e III. Os dados obtidos foram submetidos ao tratamento estatístico pelo teste Exato de Fisher com nível de significância de 5%. Os resultados demonstraram uma diferença estatisticamente significante entre as curvaturas não fisiológicas da coluna vertebral e as relações vertical e ântero-posterior de oclusão, assim como diversos tipos de mal oclusão dentária entre indivíduos com curvaturas não fisiológicas da coluna vertebral. Não foi observada relação estatisticamente significante entre gênero e idade nos indivíduos examinados. Conclui-se que há um desequilíbrio no sistema manducatório pode estar intimamente relacionado a presença de alterações posturais na coluna vertebral.

This study aims to verify the relation between dental occlusion and no physiological curvature of the spinal column. The sample consisted of 88 individuals with a clinical diagnosis and confirmed radiographic postural deviation, treated at Medical-Dental Clinic in the state of Joao Pessoa-Pb. For data collection it was carried out a clinical examination of the dental occlusion in vertical relationship of normality, bite the top, open and deep. Later the transversal occlusion was qualified inrelation normality, midline deviation, crowding and posterior crossbite. The vertical anterior-posterior occlusion relation was determined according to Angle classification: normal, class I, II and III. The obtained data were subjected to statistical analysis by Fisher exact test with a significance level of 5%. It was found that there was a difference statistically significant between the non-physiological curvatures of the spine and the vertical and ânterior-posterior occlusion relation as well as various types of dental malocclusion among individuals with no physiological curvature of the spine. No statistically significant relationship between gender and age it was observed. Data suggest there isan imbalance in the system can be closely related to the presence of postural changes in the spine.

Gingivitis and salivary osmolality in children with cerebral palsy.

AIM: To investigate the influence of salivary osmolality on the occurrence of gingivitis in children with cerebral palsy (CP). DESIGN: A total of 82 children with spastic CP were included in this cross-sectional study. Oral motor performance and gingival conditions were evaluated. Unstimulated saliva was collected using cotton swabs, and salivary osmolality was measured using a freezing point depression osmometer. Spearman's coefficient, receiver operating characteristic (ROC), and multiple logistic regression analyses were performed. RESULTS: Strong correlation (r > 0.7) was determined among salivary osmolality, salivary flow rate, visible plaque, dental calculus, and the occurrence of gingivitis. The area under the ROC to predict the influence of salivary osmolality on the occurrence of gingivitis was 0.88 (95% CI 0.81-0.96; P < 0.001). The cutoff value of 84.5 for salivary osmolality presented good sensitivity and specificity, both higher than 77%. The proportion of children presenting salivary osmolality ≤84.5 mOsm/kgH2 O and gingivitis was 22.5%, whereas for the group presenting osmolality >84.5 mOsm/kgH2 O, the proportion of children with gingivitis was 77.5%. Salivary osmolality above 84.5 increased the likelihood of gingivitis fivefold, whereas each additional 0.1 mL of salivary flow reduced the likelihood of gingivitis by 97%. CONCLUSION: Gingivitis occurs more frequently in children with CP showing increased values of salivary osmolality.

Salivary flow rate and biochemical composition analysis in stimulated whole saliva of children with cystic fibrosis.

OBJECTIVE: It is recognized that cystic fibrosis (CF) patients present a risk for oral diseases, since it affects exocrine glands, and the treatment consists of a carbohydrate-rich diet. Recognizing the protective function of saliva on maintaining oral health, the aim of the study was to evaluate salivary parameters in stimulated whole saliva from children with CF. METHODS: A case-control study was conducted comparing stimulated whole saliva of healthy (n=28; control group) and CF children (n=21; experimental group). Salivary flow rate, initial pH, buffer capacity (total and in each range of pH), total protein and sialic acid (total, free, and conjugated) concentration, α-amylase and salivary peroxidase activities were evaluated. Data were compared by two-tailed Student t test (95% CI; p ≤ 0.05). RESULTS: CF patients presented a significant reduction in salivary parameters compared with the control group (p ≤ 0.05): salivary flow rate (36%), buffer capacity (pH range from 6.9 to 6.0), sialic acid concentration (total 75%, free 61%, and conjugated 83%); α-amylase and salivary peroxidase activities (55%). Additionally, a significant increase in total protein concentration (180%) of stimulated whole saliva from CF patients was verified compared with the control group (p ≤ 0.05). CONCLUSION: Children with CF presented significant changes in salivary composition, including salivary flow rate, buffering capacity and protective proteins of the oral cavity, compared with children without CF.

Biofilme dental em crianças com erosão dentária / Dental biofilm in children with dental erosion

Objetivo: o presente estudo quantificou o biofilme dental por meio do índice de higiene oral simplificado (IHO-S) de Greene e Vermillion, em crianças com erosão dentária, comparando-as com crianças sem esse problema de saúde bucal. Sujeitos e método: participaram do estudo quarenta crianças, de quatro a nove anos de idade, examinadas por um único examinador treinado de acordo com o índice de O´Brien para o diagnóstico de erosão dentária, sendo que vinte crianças apresentavam erosão nos dentes e vinte crianças não a apresentavam. Posteriormente, elas receberam orientaçõese padronização para a avaliação do IHO-S. Os dados foram analisados pela regressão logística univariada de Poisson. Valores de razão de prevalência (RP) e intervalos de confiança de 95% (IC 95%) foram calculados. Resultados: a média (desvio padrão) do IHO-S de crianças com erosão foi de 1,20 (0,40), menor que as crianças do grupo controle 1,75 (0,45). A quantidade de biofilme foi associada à presença de erosão dentária (RP IC 95% = 0.390; 0.180-0.833) e valor de p = 0.027. Conclusões: crianças com erosão nos dentes apresentaram uma quantidade significativamente menor de biofilme em relação às crianças sem esse problema. O biofilme pode ser um possível fator protetor contra os ataques ácidos e o desenvolvimento da erosão dentária.

Percepções, conhecimentos e representações de saúde bucal em adolescentes de escolas públicas e privadas do município de Atibaia,SP / Perceptions, knowledge and representations of oral health among adolescents in public and private schools in the city of Atibaia-SP

Estudos sobre autopercepção da saúde bucal na adolescência são raros, reforçando o mito de que na adolescência existem poucos agravos à saúde de forma geral. Objetivo: conhecer os adolescentes quanto ao perfil socioeconômico e de doenças bucais, assim como o impacto delas no cotidiano e os fatores etiológicos implicados. Sujeitos e método: foram analisados e avaliados por inquérito adolescentes (n=183) de escolas de ensino fundamental pública (EPU) e privada (EPR), de Atibaia, SP. A análise foi realizada por frequência, teste exato de Fisher e Kruskall Wallis, com IC 95%. Resultados: da amostra, 48,6% sujeitos estudam em EPR, 54,6%pertencem ao sexo feminino, 77% tem entre 12 e 15 anos e 33% entre 16 e 18 anos. Não houve diferença de ingestão diária de carboidrato entre os alunos da EPR e da EPU, mas, sim, quanto ao conhecimento da relação de tal ingestão com a cárie, sendo que os alunos da EPR os que mais correlacionam (P<0,0001) e os da EPU os que menos conhecem prevenção (p<0,0001). Quanto à correlação entre doença periodontal (DP), formas de prevenção e sinais e sintomas, houve diferença entre EPU e EPR. A não associação entre sangramento espontâneo ao escovar e mau hálito com DP foi maior para EPR, embora tenha havido maior frequência de conhecimento sobre prevenção. No tema renda, os alunos da EPR enquadraram-se na faixa entre quatro e seis, ou acima de seis, salários-mínimos, e os da EPU, de um a três, e de quatro a seis salários salários-mínimos. Conclusão: os adolescentes oriundos de famílias de menorrenda demostraram menor conhecimento em relação à etiologia das doenças, prevenção e manutenção da saúde bucal; as meninas apresentaram maior preocupação e maior informação, evidenciando autopercepção mais forte para saúde bucal.
