title: [The relationship between gingival condition and socio-demographic factors of adolescents living in a Brazilian region].
abstract: The scope of this study is to correlate the gingival condition and sociodemographic status of adolescents living in an economically disadvantaged Brazilian region. The survey was conducted with a random sample of 450 adolescents in 13 cities selected in the Jequitinhonha Valley (State of Minas Gerais). The gingival condition was evaluated using a calibrated examiner (Kappa ≥ 0.85). The oral exam was based on the Community Periodontal Index (CPI). The frequencies of individuals were calculated and sextants subsequently assessed using Multiple Correspondence Analysis (ANACOR) to reveal the relationship between CPI and sociodemographic characteristics. The results showed that: 16 (3.6%) were healthy; 235 (52.2%) had gingival bleeding; 36 (8%) had dental calculus and 163 (36.2%) had both bleeding and calculus. ANACOR identified two groups with similarities in relation to periodontal disease. Group one featured 19-year-olds with healthy CPI who work and have higher family income. Group two included 15- and 16-year-olds of both sexes with CPI and gingival bleeding in elementary school with lower family income, who declared themselves to be of mixed or Afro-descendant race. The presence of gingivitis was related to the socioeconomic and demographic characteristics of adolescents in the region.
