Clinical attachment loss and its association with risk indicators in Brazilian adolescents and young adults/ Perda de inserção clínica e sua associação com indicadores de risco em adolescentes e jovens brasileiros

ABSTRACT

Purpose: This cross-sectional study aimed to determine the prevalence of periodontal clinical attachment loss in 622 Brazilian adolescents and young adults (15 to 25 years) and its correlation with age, gender and smoking habits. In addition, to evaluate the influence of different cut-off points on the prevalence data. Materials and Methods: full-mouth periodontal examination was conducted by two trained and calibrated examiners to measure periodontal probing depth(PPD) and clinical attachment level (CAL) at 6 sites per tooth using a manual periodontal probe. The data analysis was performed in a subject level according to three cut-off points (CAL ≥ 1mm, 2mm or 3mm). Statistical analysis was conducted using Wilcoxon, Student-t and Mann Whitney tests (p < 0.05). The association between age and CAL was also analyzed by OR calculation. Results 454 subjects presented CAL of 1mm, 341 of 2mm and 251 of 3mm. In each cut-off point it was not observed significant differences between males and females, neither between smokers and non-smokers. Only age was associated with...

RESUMO

O objetivo deste estudo transversal é determinar a prevalência de perda de inserção clínica em 622 adolescentes e jovens brasileiros (15 a 25 anos) e a correlação existente com idade, gênero e tabagismo. Além disso, avaliar a influência de diferentes pontos de corte na prevalência observada. Material e métodos: dois examinadores treinados e calibrados realizaram as mensurações de profundidade de sondagem (PPD) e nível clínico de inserção (CAL) em 6 sítios utilizando sonda periodontal manual. Os dados analisados foram apresentados de acordo com os pontos de corte (CAL≥ 1mm, 2mm ou 3 mm). Análise estatística foi realizada utilizando os testes de Wilcoxon, Student-t e Mann Whitney (p< 0,05). A associação entre idade e CAL foi analisada...
