  ABSTRACT: AIM: The aim of this study was to assess the influence of custom-fit mouthguards on the aerobic performance of soccer and futsal players under 17 (U-17). MATERIAL AND METHODS: Forty players from 3 Brazilian clubs participated in the study. The athletes' aerobic performance was assessed through the 20-meter shuttle-run test. All athletes performed two tests with and without mouthguard. Two outcome variables were analyzed: (i) the total distance covered in the test (meters) and (ii) the maximum oxygen uptake (VO2 max). A questionnaire assessing the level of acceptance of mouthguards considering different parameters was administered to the athletes before the delivery of the mouthguards and after 2 weeks of use. The questionnaire used a visual analogue scale (VAS). Paired t-test was used to compare the results obtained from the shuttle-run tests and the questionnaires. RESULTS: Mouthguards did not influence the aerobic performance of the players, considering both the total distance covered in the tests and the VO2 max. Stability was the parameter with the highest acceptance. Levels of acceptance regarding breathing (P = 0.022) and communication (P = 0.002) increased after mouthguards usage. Communication had the lowest level of acceptance considering all parameters assessed. Only 10% of the players reported receiving recommendations to use mouthguards while playing football or futsal. None of the participants reported having used mouthguards before. CONCLUSIONS: The use of custom-fit mouthguards does not affect the aerobic performance of soccer and futsal U-17 players. Future studies should focus on the development of appliances with maximum protection and minimum influence on communication.

  ABSTRACT: The objective of this study was to assess the prevalence and characteristics of oral lesions and oral self-examination and the association between these variables and life course determinants in a young population. A representative sample (n = 720) of all births occurring in Pelotas, Rio Grande do Sul State, Brazil, in 1982, was investigated and the outcomes were assessed in 2006. Data regarding exploratory variables was collected from other cohort waves. The prevalence of oral lesions was 23.3% (95%CI: 20.3-26.6). A total of 31% of individuals (95%CI: 27.6-34.4) reported never having performed oral self-examination. Multivariable analysis showed that low socio-economic status at birth, lack of oral hygiene instruction from a dentist up to the age of 15 years and smoking habits at the age of 22 year were associated with the presence of oral lesions. Performing oral self-examination was associated with high levels of maternal schooling at birth and having received oral hygiene orientation from a dentist up to the age of 15 years. Socioeconomic and behavioral factors are associated with both presence of oral mucosal lesions and the habit of performing self-examination.

  ABSTRACT: 155 Factors associated with prevalence of oral lesions and oral self-examination in young adults from a birth cohort in Southern Brazil Fatores associados à prevalência de lesões bucais e à realização do autoexame bucal em adultos jovens de uma coorte de nascidos vivos do Sul do Brasil Factores asociados a la prevalencia de lesiones bucales y a la realización del autoexamen bucal en adultos jóvenes de una cohorte de nacidos vivos del sur de Brasil Abstract The objective of this study was to assess the prev-alence and characteristics of oral lesions and oral self-examination and the association between these variables and life course determinants in a young population. A representative sample (n = 720) of all births occurring in Pelotas, Rio Grande do Sul State, Brazil, in 1982, was investigated and the outcomes were assessed in 2006. Data regard-ing exploratory variables was collected from other cohort waves. The prevalence of oral lesions was 23.3% (95%CI: 20.3-26.6). A total of 31% of indi-viduals (95%CI: 27.6-34.4) reported never having performed oral self-examination. Multivariable analysis showed that low socio-economic status at birth, lack of oral hygiene instruction from a dentist up to the age of 15 years and smoking habits at the age of 22 year were associated with the presence of oral lesions.

  ABSTRACT: OBJECTIVE: Studies on gingivitis in children and adolescents are scarce and the results are inconclusive. The aim of this study was to assess the prevalence and extension of gingivitis and associated factors in Brazilian schoolchildren. METHODS: Cross-sectional data from 1,211 schoolchildren 8 to 12 years old from Southern Brazil in 20 public and private schools were analyzed. Socioeconomic, demographic, and oral hygiene habits were assessed by questionnaires answered by parents and children. Buccal examination assessed presence of plaque, crowding, and gingivitis. Data were analyzed using Poisson regression [prevalence ratio (PR); 95% confidence interval (CI)]. RESULTS: Prevalence of visible plaque was 89.7% (95% CI 88.0-91.3) and gingival bleeding on probing was 78.4% (95% CI 76.1-81.0). The mean and median numbers of sites with gingival bleeding were 3.10 and 2 (SD ± 3.22), respectively. In multivariate adjusted analysis, the presence of a greater number of sites with plaque was significantly associated with gingivitis (PR 1.26; 95% CI 1.07-1.47) and its extension (PR 1.96; 95% CI 1.53-2.51). Lighter-skinned black children had a lower probability of having severe gingivitis (PR 0.69; 95% CI 0.48-0.98) compared with white children. This association was observed after adjusting for other variables. CONCLUSIONS: Gingivitis was associated with higher number of sites with plaque and with skin color, reflecting the influence of biological and demographic factors on this oral condition.

  ABSTRACT: BACKGROUND: Evaluation of the frequency and need for treatment of dental trauma is critical for both planning and establishing dental services and preventive programs. AIM: This cross-sectional study evaluated the prevalence of dental trauma, need for treatment and factors associated with dental visits after an injury. SUBJECTS AND METHODS: A multistage sample of children aged 8-12 years, from 20 private and public schools in Pelotas/Southern Brazil, was considered. Socioeconomic information was collected from parents, and data regarding traumatic events were obtained from the children. Clinical examinations were conducted using validated criteria. Descriptive analysis and logistic regression were used to assess the factors associated with search for treatment after injury. RESULTS: A total of 1210 children were included, 153 (12.6%, 95% CI 10.8-14.6) of whom suffered dental trauma, with a total of 175 traumatized teeth. The most frequently observed type of injury was enamel fracture, affecting 129 (73.7%) teeth, of which 107 did not require restorative treatment. A total of 68 (38.8%) teeth required care, of which 24 (13.7%) received treatment. Of the children who recalled the trauma, 39 (36.5%) sought treatment, which was significantly associated with both higher maternal education (OR 2.75; 95% CI 1.18-6.41) and trauma severity (OR 7.71; 95% CI 3.17-18.75). CONCLUSIONS: The prevalence of traumatic injuries was relatively high in this population. Although most of the traumatized teeth did not require treatment, dental care was neglected, as most of the children were not taken to a dentist for evaluation. Also, there was a considerable demand for treatment, most of them of low complexity. Special attention should be given to children whose mothers have completed fewer years of education, as the mother's level of education was an important predictor of evaluation by a dentist after injury.
