The data suggest that tooth erosion was associated with age and presence of hypoplasia. It may indicate the need of strategies to diagnose in early stages and to minimize consequences.

BackgroundObservational studies have suggested that traumatic dental injuries (TDI) can lead to pain, loss of function and esthetic problems, with physical, emotional and social consequences for children and their families. However, population-based studies that investigate the impact of TDI on oral health-related quality of life (OHRQoL) among preschool children are scarce and offer conflicting results. The aim of the systematic review and meta-analysis was to evaluate the impact of TDI on OHRQoL among preschool children (PROSPERO-CRD42015032513).MethodsAn electronic search of six databases was performed in PubMed (MEDLINE), ISI Web of Science, Scopus, Science Direct, EMBASE and Google Scholar, with no language or publication date restrictions. The eligibility criteria were TDI as the exposure variable, OHRQoL as the outcome and a population of children up to six years of age. RevMan software was used for data analysis. Results are expressed as odds ratios with 95% confidence intervals for the total score of the Early Childhood Oral Health Impact Scale (ECOHIS) as well as the scores of the Child Impact Section (CIS) and Family Impact Section (FIS). The random effect model was chosen and heterogeneity was evaluated using the I2 test.Results2,013 articles were initially retrieved; 1,993 articles were excluded based on title and abstracts; 10 articles excluded after full-text analysis. Ten studies comprising a population of 7,461 preschool children were included in the systematic review and nine studies were included in the meta-analysis. TDI caused a negative impact on OHRQoL based on the overall ECOHIS (OR: 1.24; 95% CI: 1.08–1.43) and CIS (OR: 1.23; 95% CI: 1.07–1.41), but not the FIS (OR: 1.09; 95% CI: 0.90–1.32).ConclusionsTDI negatively impacted on OHRQoL of preschool children. The present findings indicate the need for TDI prevention and treatment programs in early childhood.

OBJECTIVE Identifying, through a systematic literature review, evidence of a possible association between obesity and dental caries. METHODS A search of articles published between 2005 and January 2012 was performed in the Medline/PubMed, LILACS and Web of Science databases. The quality of scientific evidence of the selected articles was assessed by the items proposed for observational studies in the Downs & Black instrument. RESULTS Initially, 537 references were found; after checking the titles and abstracts by two independent researchers, twenty-eight articles were selected for complete reading. Ten of them that assessed the primary and/or permanent dentition observed a positive association between obesity and dental caries and one study found an inverse association. According to the Downs & Black classification, thirteen articles with good scientific evidence were found. CONCLUSIONS The present review did not find sufficient evidence regarding the association between obesity and dental caries, and it did not clarify the possible role of diet and other possible effect modifiers on this association.

Oral squamous cell carcinoma (OSCC) is the fifth most common type of cancer in the world. The effect of some etiological factors is well established in the literature, such as consumption of tobacco and alcohol. However, approximately 15 to 20% of all oral cancer cases occur in patients without the traditional risk factors, reflecting in numerous cases of OSCC in non-smokers and non-alcoholic drinkers. Also, several studies have suggested a possible association between human papillomavirus and OSCC. Under these aspects, the purpose of this study is to address cases of oral cancer in non-smokers and non-drinkers focusing on the role of HPV, thus contributing to improve the diagnosis and monitoring of OSCC. A computer database search was performed using the Pubmed database. The search key words were: epidemiology, oral squamous cell carcinoma, risk factors and human papillomavirus. It is important to assess patients without the potential risk factors, since this knowledge may help identifying other features associated with the occurrence of oral cancer, enabling an appropriate clinical management and monitoring.

Background: Prevalence data about tooth erosion has attracted increasing attention in the dental community; however, no study has addressed the impact of this condition on child oral health-related quality of life (COHRQoL). This study assessed the impact of tooth erosion on COHRQoL. Methods: This study followed a cross-sectional design, with a multistage random sample of 944 11- to 14-year-old children representative of Santa Maria, a southern city in Brazil. They were examined for recording the prevalence and severity of tooth erosion by 2 examiners. Children completed the Brazilian version of Child Perceptions Questionnaire (CPQ_11–14) and data about socioeconomic variables of the target population were collected by means of a structured questionnaire. The Poisson regression model using robust variance was performed to assess the association between the predictor variables and the outcomes. Results: Prevalence of tooth erosion (7.2%) and severity were low. Poisson regression models showed a distinct gradient in mean CPQ_11–14 scores by socioeconomic indicators. Children with tooth erosion with low levels of severity did not report higher means in the total scores or domains of CPQ_11–14. Conclusion: The presence of tooth erosion of low severity did not have a significant negative impact on the children’s perception of oral health or on their daily performance.
