Impact of dental treatment and the severity of traumatic dental injuries on the quality of life of Brazilian schoolchildren.

BACKGROUND/AIMS: Traumatic dental injuries (TDI) are most prevalent during adolescence and infancy, and they have an important impact on the oral health-related quality of life (OHRQoL). The aim of this study was to assess the effect of dental treatment and the severity of TDI on the OHRQoL of schoolchildren in public schools in Brazil. MATERIALS AND METHODS: This cross-sectional study evaluated schoolchildren aged 11 to 14 years in Brasilia, Brazil. The criteria used for the examinations were TDI-O'Brien criteria; Dental caries-DMFT criteria; and malocclusion-the Dental Aesthetic Index. The impact of oral health on the children's quality of life was assessed with the Child Perceptions Questionnaire (CPQ11-14 ) that was completed by the children while on the school premises. Socio-demographic information was also collected from the parents. Statistical analysis was performed using non-parametric and association tests, as well as linear regression. RESULTS: A total of 20.2% of the students had some TDI in their permanent anterior teeth; 20% of traumatized teeth were treated, and 80% were not treated. Sorting by severity, 75.1% of the schoolchildren had a TDI involving only the enamel, and 24.9% had a TDI extending beyond the enamel. Significant differences were observed between the severity of a TDI and the total scores of CPQ11-14 (Kruskal-Wallis; p = 0.0026), emotional well-being (p = 0.0006), and social well-being (p = 0.0001) when the group with TDI extending beyond the enamel was compared with the other groups (control and with TDI involving only the enamel), even after adjustment for socio-demographic and clinical variables. For oral symptoms and functional limitation, no differences were observed among the groups. CONCLUSIONS: Dental trauma and fractures extending beyond the enamel, treated or not, have a negative impact on the OHRQoL of schoolchildren, suggesting effects on self-perception and in the social and emotional spheres.

Early clinical performance of resin cements in glass-ceramic posterior restorations in adult vital teeth: A systematic review and meta-analysis.

STATEMENT OF PROBLEM: Dentists must regularly determine the best adhesive cementation protocol for glass-ceramic restorations on posterior teeth. The authors are aware of few in vivo follow-up studies and no meta-analyses, including clinical trials, regarding this clinically relevant topic, which merits further investigation. PURPOSE: The purpose of this systematic review and meta-analysis was to statistically analyze the clinical performance of glass-ceramic posterior restorations by using a descriptive synthesis based on the integrity of the tooth and restoration under different cementation protocols for self-adhesive or conventional resin cements. MATERIAL AND METHODS: The electronic databases Cochrane, LILACS, PubMed/MEDLINE, SciELO, Scopus, and Web of Science were used to identify relevant clinical trials. Non-peer-reviewed literature searches and hand searching were performed to find additional references. Language, participant's age, or time restrictions were not set. Restoration and tooth integrity were the 2 aspects considered for the meta-analysis. Statistical analyses were performed using a software program in which fixed or random effect models with risk ratios and 95% confidence intervals were applied. RESULTS: Three prospective randomized or quasirandomized clinical trials, published in English from 2012 onward, were selected and statistically analyzed. The integrity of the tooth and restoration was assessed at the baseline and 1 year after the restorative intervention. The statistical analyses did not show any significant differences between the intervention and control groups in terms of the integrity of the tooth and restoration. CONCLUSIONS: This meta-analysis indicated no clinical differences in the ceramic cementation using a self-adhesive or conventional resin cement after the 1-year follow-up period because both resin cements showed adequate properties for tooth and restoration integrity.
