Resumo
The aim of this study was to compare the periodontal conditions in 7-15-year-olds from Araraquara, SP, Brazil in 1998 with data from 1995. A systematic random sample was drawn from the population of children and adolescents enrolled in all public schools in 1998. The survey was conducted by trained examiners using the CPITN and WHO diagnostic criteria. Results showed an increase in the percentage of students of all ages with healthy periodontal conditions (from 14% in 1995 to 33% in 1998; p < 0.01). An increase in the mean number of healthy sextants (from 3.2 to 4.4; p < 0.0001), a decrease in the mean number of bleeding sextants (from 2.5 to 1.2; p < 0.0001) and no difference in the mean number of sextants with calculus were also observed. At the age of 15, 54% of the students had 5-6 healthy sextants in 1998 compared to 19% in 1995 (p < 0.01). Despite the improvement observed in the periodontal conditions, efforts must be increased in order to achieve the WHO goal for the year 2010 of no more than one sextant affected by bleeding or calculus at the age of 15.
