Objectives: Traumatic dental injuries (TDIs) in childhood and adolescence are a potential public health problem given their prevalence and consequences. The aim of this study was to assess the impact of TDIs on the oral health-related quality of life (OHRQoL) of preschoolers and schoolchildren, by synthesizing the available evidence.Methods: A systematic search was conducted in MEDLINE, EMBASE, Cochrane, ScieLo and Lilacs databases since January 1966 until March 2016. The included studies compared OHRQoL between groups with and without TDIs, using validated instruments. The selection process and data extraction were carried out by two researchers independently. A third reviewer resolved discrepancies. Methodological quality was assessed with the Effective Public Health Practice Project's Quality Assessment Tool. Meta-analyses were performed using random effect models, separately for preschoolers and schoolchildren.Results: Of 213 identified articles, 26 studies (involving a total of 4582 patients and 13 601 controls between the ages of 1 and 15 years) met the inclusion criteria.Most of the studies had been published in the last 5 years, and their methodological quality was judged to be moderate. The TDIs group had a significantly higher chance of reporting any impact on OHRQoL than controls for both preschoolers (OR = 1.44; 95% confidence interval [CI]: 1.28-1.63; I 2 = 0%) and schoolchildren (OR = 1.31; 95% CI: 1.04-1.66; I 2 = 70%). In preschoolers, the OR for OHRQoL impact for complicated vs uncomplicated TDIs was 1.53 (95% CI: 1.04-2.26;The social domain was the most affected one in schoolchildren (standard mean difference = 0.34; 95% CI: 0.13, 0.55; I 2 = 68%).
Conclusion:Traumatic dental injuries have a negative impact on OHRQoL of both preschoolers and schoolchildren. Outcome standardization to measure OHRQoL impact, such as mean score differences and cut-off points, is needed. Prospective cohort studies are recommended to confirm these findings and to understand how TDIs' impact changes with time.

Objectives:The aim of this study was to conduct a systematic review in order to assess the impact of early childhood caries (ECC) and its severity on Oral health-related quality of life (OHRQoL).
Materials and Methods: An electronic search was conducted in MEDLINE, EMBASE, Cochrane, SciELO and Lilacs databases. The study eligibility criteria were primary studies published in English, Spanish or Portuguese that assessed OHRQoL in preschool children with dental caries using validated instruments. Two researchers independently performed the selection process and data extraction. The Effective Public Health Practice Project's Quality Assessment Tool was used for the quality assessment. Random effects models were used to estimate the pooled effect for continuous and categorical data.Results: Of 2,037 identified articles, thirty-five studies (37 articles) met the inclusion criteria. The methodological quality was judged mainly as moderate. Children with ECC were more likely to report any impact on OHRQoL than children without caries (OR: 1.99; 95% CI: 1.51-2.62; 6 studies). Severe ECC (dmft > 5) presented a higher effect (OR: 5.00; 95% CI: 3.70-6.74; 8 studies). Sensitivity analysis including only population studies showed uncertain results on the impact of ECC on OHRQoL (OR:
Objectives: Early childhood caries (ECC) constitutes a serious public health issue, especially in communities without water fluoridation. We assessed the effectiveness of biannual fluoride varnish applications to prevent ECC in children from nonfluoridated rural areas.Methods: A triple-blind randomized control trial with two parallel arms was conducted with 275 two-to three-year-old children without cavitated carious lesions from 28 rural public preschools in Chile. The preschools were located in areas of low socioeconomic status without access to fluoridated water. An oral health education component was administered to children, parents and educators. A new toothbrush and toothpaste for each child was delivered to the parents at baseline and at four follow-up visits. The participants were randomly allocated to receive fluoride varnish or placebo applications every six months. Trained, calibrated dentists blind to the treatment arm performed visual dental assessments at 6, 12, 18 and 24 months. The primary endpoint was the development of cavitated carious lesions in children during the 24-month follow-up period using WHO criteria, and the secondary outcomes were an increase in caries measured as a change in the index of decayed, missing or filled teeth (dmft) since the beginning of the study and the development of adverse effects. An intention-to-treat (ITT) approach was used for the primary analysis.Results: We included 131 participants in the intervention group and 144 participants in the placebo group; of these children, 89 (67.9%) in the intervention group and 100 (69.4%) in the control group completed the protocol. The comparative ITT analysis of caries incidence after 24 months of follow-up showed a between-group prevention fraction of 18.9% (À2.9%-36.2%). Caries incidence was 45.0% for the experiment group and 55.6% for the control group (P = .081), with a mean dmft of 1.6 (SD = 2.4) and 2.1 (SD = 2.5), respectively. No adverse effects were reported.
Conclusions:In conclusion, biannual fluoride varnish application is not effective in preschool children from rural nonfluoridated communities at a high risk of caries.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
