Are Premature Birth and Low Birth Weight Associated with Delay on the Eruption of Deciduous Teeth? A Systematic Review and Meta-analysis

ABSTRACT Objective: To investigate whether children with premature birth (PB) and/or with low birth weight (LBW) have different tooth eruption patterns than those born at term or with normal weight. Material and Methods: Searches were performed in the PubMed, Cochrane Library, Sc1opus, Web of Science, LILACS, and BBO databases as well as the grey literature. Three independent reviewers were involved in study selection, data extraction, and bias assessment. The risk of bias was assessed using the Modified Newcastle-Ottawa Scale. Meta-analysis was conducted to compute the mean difference (MD) in mean chronological or adjusted age at the eruption of the first deciduous tooth between preterm children and those born at full term. The GRADE approach was used. Results: Among a total of 316 articles identified, 21 were eligible for inclusion and three were included in the meta-analysis. PB was associated with the delay in the first tooth deciduous eruption when chronological age was considered (MD: 1.36; 95%CI: 1.02-1.69) but not when considering adjusted age (MD: -0.30; 95%CI: -0.67-0.07). The evidence was graded as having very low quality. Conclusion: Based on a low certainty of evidence the PB is associated with the delayed eruption of the first deciduous tooth when considering chronological age but not when adjusted age is considered.

Oral manifestations and dental approach in pediatric patient with lamellar congenital ichthyosis: 36-month follow-up

Introduction: Lamellar ichthyosis is an autosomal recessive congenital disease that causes dryness of the skin in the perioral region, which leads to pain during dental hygiene. Thus, the diet of patients with this disease tends to be pasty, which can lead to oral problems. Hyposalivation is suspected to be an oral manifestation of lamellar ichthyosis and may exert an influence on the incidence of carious lesions. Objective: Describe the treatment of a female patient diagnosed with lamellar ichthyosis who sought dental care initially when two years of age with complaints of dental pain, feeding difficulties and low weight. Case report: Atraumatic restorative treatment, extractions and topical application of fluoride varnish were performed in the patient, aesthetic of posterior installation of space, which also functioned as a rehabilitator. Conclusion: This study reinforces the need for the follow-up of the patient with LI by the dental surgeon since the birth of the first tooth, as dryness of the perioral skin and hyposalivation are conditions reported in individuals with lamellar ichthyosis. These conditions can affect oral hygiene and the frequency of carious lesions.

Introdução: A ictiose lamelar é uma doença congênita autossômica recessiva que causa ressecamento da pele na região peribucal, o que leva à dor durante a higiene dental, por isso a alimentação dos pacientes com essa doença tende a ser pastosa, podendo levar a problemas bucais. Suspeita-se que a hipossalivação possa ser uma manifestação oral da ictiose lamelar, podendo influenciar na incidência de lesões cariosas. Objetivo: Descrever o tratamento de uma paciente do sexo feminino, inicialmente com 2 anos de idade, diagnosticada com ictiose lamelar (IL), que procurou atendimento odontológico com queixa de dor dentária, dificuldade na alimentação e baixo peso. Relato do caso: Tratamento restaurador atraumático, exodontias e aplicação tópica de verniz fluoretado foram realizados na paciente, além de posterior instalação de mantenedor de espaço, o qual também funcionou como reabilitador estético. Conclusão: Este estudo reforça a necessidade do acompanhamento do paciente com IL pelo cirurgião dentista desde o nascimento do primeiro dente, pois secura da pele perioral e hipossalivação são condições relatadas em indivíduos com ictiose lamelar. Essas condições podem afetar a higiene bucal e a frequência de lesões cariosas.

Are technology-based health education methods able to reduce oral health inequalities between the sexes in adolescents? A cluster randomized trial.

PURPOSE: Determine if different technology-based health education interventions can reduce oral health inequalities between the sexes in a sample of adolescents. METHODS: A cluster randomized clinical trial was conducted in three phases with an initial sample of 291 male and female adolescents 14-19 years of age. Phase I (n = 288) comprised a clinical examination performed by a calibrated examiner using the simplified oral hygiene index (OHI-S) and gingival bleeding index (GBI). Phase II involved two educational interventions: video (VD; n = 147) or oral counselling (OR; n = 141) with standardized content. In phase III, an App was made available to half of the clusters (OR + App; n = 66/OR without App; n = 71/VD + App; n = 63/VD without App; n = 63), and the clinical examination was performed a second time. Data were evaluated using descriptive analysis and nonparametric tests. RESULTS: In phase I, boys had a lower standard of oral hygiene compared with girls, with higher mean OHI-S (p = 0.039) and GBI (p = 0.015). After VD and OR interventions, no significant difference between sexes was found regarding the mean OHI-S. However, males had a higher mean GBI compared with females in the OR group (p = 0.006). When the App was added to OR and VD groups, males in the 'OR without App' group had a higher mean GBI compared with females (p = 0.007). CONCLUSION: This clinical trial demonstrated that educational interventions involving information technologies were effective at reducing oral health inequalities between the sexes among adolescents. However, oral counselling alone was not efficient in reducing GBI in male adolescents.

Performance of ICDAS e-learning program in teaching graduate students on the detection of occlusal caries / Desempenho do programa de aprendizagem eletrônico ICDAS no ensino de alunos de pós-graduação na detecção de cáries oclusais

ABSTRACT Objective: The aim was evaluate the validity and reproducibility of the International Caries Detection and Assessment System (ICDAS) in detecting occlusal caries among graduate students after training using the e-learning program. Methods: A sample of forty-two primary teeth with different ranges of occlusal caries was selected. All teeth were mounted on a wax support and standardized photographs (EOS Rebel XTI, Canon, NY, USA) of the occlusal surfaces were taken. An experienced researcher randomly selected one specific site on the occlusal surface of each tooth to be examined later. Fifteen graduate students with no previous experience in the ICDAS scores completed the ICDAS e-learning program in Portuguese. After the training, visual examination of the occlusal surfaces was taken twice, independently, with a two-week interval. After visual examination, the teeth were longitudinally sectioned 1mm away from the previously selected occlusal site. The teeth were fixed on a wax support and photographed. Histological analysis was performed from these photographs by an experienced researcher to evaluate the depth of demineralization. Results: The Intraclass Correlation Coefficient (ICC) inter-examiner values among all participants varied from 0.54 to 0.96 and intra-examiner ICC reproducibility of the examiners ranges from 0.61 to 0.85, showing good to excellent reproducibility. For detection of enamel and dentine lesions (D1), ICDAS obtained sensitivity 0.835 and specificity 0.756. For dentine lesions (D3), the method revealed an increase in sensitivity but specificity was similar to D1. Conclusion: ICDAS e-learning training program was efficient for the training of caries lesions detection among graduate students.

RESUMO Objetivo: O objetivo foi avaliar a validade e a reprodutibilidade do Sistema Internacional de Detecção e Avaliação de Cárie (ICDAS) na detecção de cárie oclusal entre estudantes de pós-graduação após o treinamento usando o programa de e-learning. Métodos: Foi selecionada uma amostra de 42 dentes decíduos com diferentes faixas de cárie oclusal. Todos os dentes foram montados em um suporte de cera e foram tiradas fotografias padronizadas (EOS Rebel XTI, Canon, NY, EUA) das superfícies oclusais. Um pesquisador experiente selecionou aleatoriamente um local específico na superfície oclusal de cada dente para ser examinado posteriormente. Quinze estudantes de pós-graduação sem experiência anterior com o ICDAS concluíram o programa de e-learning em português. Após o treinamento, o exame visual das superfícies oclusais foi realizado duas vezes, independentemente, com intervalo de duas semanas. Após o exame visual, os dentes foram seccionados longitudinalmente a 1mm do local oclusal previamente selecionado. Os dentes foram fixados em um suporte de cera e fotografados. A análise histológica foi realizada a partir dessas fotografias por um pesquisador experiente para avaliar a profundidade da desmineralização. Resultados: Os valores interexaminadores do Coeficiente de Correlação Intraclasse (ICC) entre todos os participantes variaram de 0,54 a 0,96 e a reprodutibilidade intra-examinador do ICC dos examinadores variou de 0,61 a 0,85, mostrando reprodutibilidade boa a excelente. Para detecção de lesões de esmalte e dentina (D1), o ICDAS obteve sensibilidade 0,835 e especificidade 0,756. Para lesões de dentina (D3), o método revelou um aumento na sensibilidade, mas a especificidade foi semelhante ao D1. Conclusão: O programa de treinamento em e-learning do ICDAS foi eficiente no treinamento de detecção de lesões de cárie em estudantes de pós-graduação.

Are Information Technologies Capable of Stimulating the Use of Dental Floss by Adolescents? A Cluster Randomised Clinical Trial.

PURPOSE: To analyse the effect of information technologies on improving the frequency of the use of dental floss among adolescents. MATERIALS AND METHODS: A randomised, controlled clinical trial was conducted with 291 adolescents (mean age: 16.1 years) in three phases. Phase I involved the application of a questionnaire and clinical examinations using the simplified Oral Hygiene Index and gingival bleeding index. In phase II, the adolescents were randomly allocated to four groups: oral counseling (OR) and the use of an application (App) for smartphones; OR without the app; video (VD) and app; and VD without app. Messages were set through the app for 30 days. Phase III involved the second administration of the questionnaire and clinical examination. The frequency of dental floss use was evaluated in phases I and III. The groups were categorised into the use of technology (VD and/or App) and non-use of technology (OR alone). RESULTS: Statistically significant reductions in the clinical indices were found with all educational methods (p < 0.005) and improvements were found in the use of dental floss (p < 0.001). Moreover, information technologies were associated with an improvement in the frequency of dental floss use (p < 0.033). CONCLUSION: All methods were effective at improving clinical indicators. The use of information technologies can be considered an effective tool for improving dental floss use among adolescents.

Association Between Periodontal Health Knowledge and Oral Hygiene in Brazilian Adolescents

Abstract Objective: To evaluate the influence of oral health knowledge in adolescents' oral hygiene pattern. Material and Methods: Cross-sectional study involving 291 participants aged between 14 and 19 years old enrolled in a public school in Curitiba, Brazil. A self-administered questionnaire containing five affirmations about periodontal diseases and their forms of prevention was arranged on a three-point Likert scale. Correct answers were given a weight=1 and incorrect ones, weight=0. The knowledge score (KS) was determined by the sum. Socioeconomic and demographic data were obtained by a questionnaire sent to those responsible. The oral hygiene pattern was evaluated through the simplified oral hygiene index (OHI-S) by a calibrated researcher (K=0.89). Mann-Whitney U test and univariate and multivariate Poisson regression with robust variance were used for data analysis (α=0.05). Results: There was an inversely proportional association between KS and OHI-S (p=0.018). The multiple model showed that adolescents with a lower KS (PR = 0.93, CI95%: 0.88-0.99), male gender (PR = 1.17, CI95%: 1.01-1.37) and whose caregivers presented a lower level of education (PR=1.30, CI95%: 1.03-1.64) showed a higher index of dental plaque. Conclusion: The level of oral health knowledge, the gender and the caregivers' level of education influences the adolescents' oral hygiene pattern.

Improving adolescents' periodontal health: evaluation of a mobile oral health App associated with conventional educational methods: a cluster randomized trial.

BACKGROUND: Adolescence is a decisive period in the construction of new conduits. OBJECTIVE: The influence of an App associated with conventional educational methods in adolescents' oral health. STUDY DESIGN: Randomized controlled trial including 291 participants (mean age = 16.1 years) in baseline. The study consisted of four phases. Interventions were evaluated through the knowledge score (KS) and oral indexes (OHI-S/GBI). KS was obtained through five affirmations about periodontal diseases applied in different moments (pre-test, post-test, and follow-up test). Phase I included pre-test and oral clinical examination. Sample was randomly divided into two groups: oral (OG) and video orientation (VG) and post-test (phase II). Phase III characterized the formation of groups: OG + App/OG without App/VG + App/VG without App. App consisted of reinforcement messages which was sent during 30 days. Phase IV comprised follow-up test and clinical evaluation. RESULTS: There was no significant difference in KS between OG/VG. Overall, App improved KS (P < 0.001). VG + App showed a significant increase in KS in the follow-up test compared to the post-test (P = 0.046). There was a significant reduction in oral indexes for all methods. CONCLUSION: App was effective in increasing knowledge, especially associated with video. The different methods were equally effective for a better standard in oral hygiene.
