Periodontal status, sociodemographic, and behavioral indicators in subjects attending a public dental school in Brazil: analysis of clinical attachment loss.
BACKGROUND
The purpose of this study was to assess the prevalence, extent, and severity of clinical attachment loss (AL) and their association with sociodemographic and behavioral parameters of subjects attending a public dental school in Brazil.


METHODS
A total of 491 consenting participants (21 to 70 years of age) submitted to a full-mouth periodontal clinical examination, assessment of missing teeth, and anamnesis questionnaires. The data were analyzed by multivariable models using logistic regression analyses. The dependent variables were moderate (> or =5 mm) and severe (> or =7 mm) clinical AL.


RESULTS
The prevalence of individuals with at least one site with clinical AL > or =5 or > or =7 mm was 72.1% and 60.9%, respectively. The mean clinical AL ranged from 2.9 to 3.9 mm, according to age. The mean frequency of sites with moderate (5 to 6 mm) and severe (> or =7 mm) clinical AL was 15.8% and 9.1%, respectively. Multivariate analyses identified smoking (odds ratio [OR] = 8.93), bleeding on probing (BOP) in >10% of sites (OR = 6.82 to 22.53), and > or =4 missing teeth (OR = 2.52) as risk indicators for clinical AL > or =5 mm in > or =10% of sites, whereas an age of 36 to 50 years (OR = 1.72), smoking (OR = 7.66), and BOP in >10% of sites (OR = 6.84 to 24.89) were considered risk indicators for clinical AL > or =7 mm in at least one site.


CONCLUSIONS
This particular Brazilian population presented a high prevalence and extent of severe periodontal disease. Age, smoking, and BOP were risk indicators associated with moderate and severe AL in this population.
