Influence of surface sealants on the quality of posterior restorations with bulk-fill composites: A 4-year randomized clinical trial.

OBJECTIVES: The aim of this study was to evaluate the clinical performance of surface sealants associated with a bulk-fill composite in posterior restorations after 4 years. METHODS: A total of 174 posterior restorations were performed on 57 participants using a self-etch adhesive system and a bulk-fill composite. The groups were then divided into the following categories: 1) without surface sealant (NoS), 2) with surface sealant Biscover (Bisco, SBi), and 3) with surface sealant Permaseal (Ultradent, SPe). Restorations were evaluated using FDI criteria at baseline and after 1 and 4 years. Statistical analysis was conducted using Kaplan-Meier survival analysis and the Chi-square test (α = 0.05). RESULTS: After 4 years, only one restoration was lost (1 in the NoS group). The fracture/retention rate (with 95% confidence interval) was 98% for NoS and 100% for both SBi and SPe (p = 0.76). The majority of secondary outcomes showed minor defects, with no significant differences among the groups (p > 0.05). However, significant differences were observed among the groups in terms of marginal staining and marginal adaptation (p = 0.03). In both items, twelve restorations (nine in NoS, one in SBi, and two in SPe) showed minor marginal discrepancies favoring the sealant groups (SBi and SPe). SIGNIFICANCE: Regardless of the use of surface sealants, the bulk-fill composite restorations showed excellent clinical performance after 4 years. However, the groups that received sealants showed better marginal adaptation and less marginal discoloration compared to those that did not receive sealants.

Oral health outcomes: the association of clinical and socio-dental indicators to evaluate traumatic dental injury profile in low income Brazilian children.

OBJECTIVE: To use clinical and socio-dental indicators to evaluate traumatic dental injury (TDI) profile in Brazilian preschool children with low income. METHODS: A cross-sectional study was carried out with children of low-income families, from 2 to 6 year-old, who attended public preschools. A clinical indicator to evaluate TDI and a socio-dental indicator to detect the impact on Oral Health-Related Quality of Life (OHRQoL) for preschoolers (Early Childhood Impact Scale - ECOHIS) were used. Impact means were obtained, and the chi-square test and odds ratio were used in order to evaluate the variables (P<0.05). RESULTS: Of the 606 children evaluated, the results were obtained from a final sample of 446 children. The prevalence of TDI was 17%. Children from 37 to 60 months (P=0.04; OR=0.59 95% CI 0.34-1.01) were associated with TDI. The mean impact on OHRQoL in the group with or without TDI was low without a statistical difference (P=0.97). CONCLUSION: Based on these findings, the association of clinical and socio-dental indicators showed low prevalence of TDI and the impact on OHRQoL was indifferent between groups with or without TDI.

Oral health outcomes: the association of clinical and socio-dental indicators to evaluate dental caries in preschool children.

Dental caries is a public health problem that impacts oral health related to quality of life (OHRQoL). This study aimed to evaluate the outcome of dental caries in children by associating clinical and socio-dental indicators. A cross-sectional study was carried out with 2 to 6-year-old children who attended public day care centers in a city in the Southeast Region of Brazil. After sample calculation, 446 children were randomly selected by eligibility criteria. Two professionals evaluated dental caries using WHO (2013) criteria and classified subjects according to early childhood caries (ECC) severity. Parents/care- givers answered a characterization questionnaire and self-reported socio-dental indicator (B-ECO-HIS). The prevalence of dental caries was 33.7%. The children with high severity of ECC had 5 times higher chance of suffering an impact on OHRQoL. The one way ANOVA test showed that the impact on OHRQoL (ECOHIS scores) was associated with ECC. The outcome dental caries in oral health presented high prevalence as clinical indicator and high impact on OHRQoL as socio dental indicator. Clinical and socio-dental indicators should be evaluated together.

Resumo A cárie dentária é um problema de saúde pública com impacto na qualidade de vida relacionada à saúde bucal (QVRSB). Este estudo teve como objetivo avaliar a cárie dentária como desfecho em saúde bucal em pré-escolares, por meio da associação de indicadores clínicos e sociodentais que avaliam a QVRSB. Um estudo transversal foi realizado com crianças de 2 a 6 anos de idade que frequentavam creches públicas de um município do sudeste do Brasil. Após o cálculo da amostra, 446 crianças foram selecionadas aleatoriamente por critérios de elegibilidade. A avaliação foi feita por dois profissionais, usando critérios da OMS, que classificaram os sujeitos de acordo com a gravidade de cárie precoce na infância (CPI). Os pais/cuidadores responderam um questionário auto- aplicado de caracterização da amostra e um indicador sociodental (B-ECOHIS). A prevalência de cárie dentária foi de 33,7%. As crianças com alta gravidade de CPI tinha cinco vezes mais chance de sofrer impacto sobre QVRSB. O teste one way ANOVA apresentou associação entre impacto na QVRSB (ECOHIS escores) e CPI. O desfecho cárie em saúde bucal apresentou alta prevalência como indicador clínico e alto impacto sobre a QVRSB como o indicador sociodental. Indicadores clínicos e sociodentais devem ser avaliados em conjunto.
