Periodontal conditions in a 7-19-year-old student population in Araraquara, São Paulo, Brazil, 1995

O objetivo deste estudo foi verificar as condições periodontais e necessidades de tratamento em crianças e adolescentes, com idades entre 7 e 19 anos, matriculados em Escolas Públicas de Araraquara, SP, Brasil, em 1995, com o propósito de se obter um banco de dados-base inicial para o monitoramento das mudanças no estado periodontal. Uma amostra de 1956 crianças e adolescentes foi examinada por duas examinadoras, previamente calibradas, usando o CPITN. Os resultados mostraram que o sangramento gengival foi a condição periodontal mais frequentemente observada em todas as idades, com média de 3,0 sextantes afetados na idade de 15 anos. A presença de cálculo dental aumentou com a idade. No grupo etário de 15-19 anos, o cálculo dental e as bolsas periodontais rasas (3,5-5,5 mm) foram observados em 39,8% e 1,6% dos adolescentes, respectivamente. Com o propósito de alcançar a meta da OMS de não mais do que um sextante com escores 1 (sangramento) ou 2 (presença de cálculo dental) do CPITN na idade de 15 anos, prioridade deve ser dada aos programas de prevenção primária para que a saúde periodontal da maioria seja beneficiada.

Noncarious Cervical Lesions and Their Association With Toothbrushing Practices: In Vivo Evaluation

Objectives: This pilot study aims to investigate the prevalence of noncarious cervical lesions (NCCLs) in a student population at the Faculty of Dentistry of Aracatuba-UNESP and to assess the potential relation between buccal hygiene habits and the presence and number of NCCLs.Methods: This study was conducted with a sample of 58 young volunteers (15 men and 43 women; mean age, 23.6 +/- 1.8 years and 22.3 +/- 2.4 years, respectively). The research was divided into three steps: 1) clinical assessment; 2) oral-hygiene practices self-report questionnaire; and 3) analysis of toothbrush filament deformations. After the clinical exam the participants were divided into two groups, a control group (without NCCLs) and a test group (NCCLs), according to NCCL presence. The data were statistically analyzed with SPSS 16.0 software, using t-test, chi(2), Fisher exact test, and Spearman correlation.Results: NCCLs were present in 53% of the subjects. The presence of NCCLs was marginally statistically associated with age (p=0.15) and proportionally more prevalent in male (80%) subjects (p=0.01). NCCLs were more concentrated in the posterior-superior quadrant (93%) in both the right (90%) and left (55%) sides of the mouth. The direct rank correlation was presented between presence of NCCLs and toothbrush firmness; and between number of NCCLs and age and force applied during toothbrushing.Conclusion: Within the limitations of this pilot study, the use of medium and hard toothbrushes and greater force applied during toothbrushing might contribute to the development and/or aggravation of NCCLs.

Use of psychoactive substances in students at a public university

Introduction: The use of psychoactive substances by the student population has been the object of various studies in Brazil. Objective: To determine the prevalence of substance use among students. Methods: Quantitative study with a closed questionnaire based on standardized assessment instruments was developed. It consists of questions related to types of psychoactive substance use, abuse, frequency and duration of use, self-criticism regarding the use, consequences of use in relation to health, and misdemeanors committed under the influence of psychoactive substances. The sample included the participation of 268 students. A total of 183 (68.3%) questionnaires were analyzed, and only those with positive result for substance abuse at some point in life, the remainder, 85 (31%) questionnaires, had negative responses to psychoactive substances. Results: Students’ responses to the two years surveyed indicated that the first psychoactive substance used was alcohol (77.9%), followed by tobacco use (10.9%), and marijuana (7.6%). Of the students surveyed, 145 (79.2%) answered that still make use of psychoactive substances, and the current frequency of use varies from one or more times per week. When asked about the possibility of being or becoming drug addicts, 169 (92.3%) responded that they are not or will not become dependent. Conclusion: The results indicate the high rate of substance use among college students surveyed, and point to their contradiction to consider such psychoactive substances harmful to their health.
