Resumo
The study aimed to describe periodontal health status and its association with individual and contextual factors among 12-
year-old schoolchildren in a midwest Brazilian capital city. This cross-sectional study included data from an oral health survey
carried out in 2010 in the city of Goiania, Brazil (n = 2, 075) and secondary data obtained from the local health authority.
Data were collected through oral clinical examinations and interviews. For assessment of periodontal status two components
of the community periodontal index (CPI) were used: calculus and bleeding after probing. Dependent variable was presence of
any periodontal condition. Independent individual variables were the children’s sex and color/race, and their mother’s level of
schooling. Contextual variables were related to the schools (type and existence of toothbrushing program) and its geographic
location in the health districts. Rao-Scott test and multilevel Poisson analysis were performed. The prevalence of calculus and/or
bleeding was 7%. Brown color, public schools, and those located in health district with intermediate socioeconomic indicators
were associated to a higher prevalence of this condition. The prevalence of adverse periodontal condition was low and the
inequalities in its distribution were determined by individual as well as contextual factors related to the schools and the geographic
area.
