title: Prevalence and determinants of periodontal disease in Portuguese adults: results from a multifactorial approach.
abstract: The purpose of the present investigation was to study prevalence of periodontal disease among 30 to 39-years-old from Oporto in the north of Portugal. In addition, an attempt was made to elucidate possible periodontal disease determinants in this population. A random sample consisting of a total of 322 individuals was drawn based on electoral lists. The attendance rate was 61%. The CPITN index was used and the results indicate a high prevalence of periodontal disease and a substantial need for periodontal treatment in this population, with 41% of the individuals investigated having one or more sites with a CPITN score 4 (pockets deeper than 5.5 mm). Dental visiting habits, gender (lower CPITN scores for females) and oral hygiene were the determinants most significantly associated with variation in CPITN scores.
