Epidemiology is the study of health and disease in populations, and of how these conditions are influenced by heredity, biology, physical environment, social environment, and personal behavior. There are many epidemiological studies in Brazilian population but few about the influence of some risk factors in periodontal conditions. This cross-sectional study was performed to assess the influence of age, sex, plaque and smoking on periodontal disease in a population from Bauru (Brazil). Data concerning periodontal status were collected from 380 patients in the University of São Paulo (USP). Measurements of periodontal pocket depths (PPD), clinical attachment levels (CAL), plaque index (PI) of four sites in all teeth were registered. The influence of age, sex and smoking habits on the periodontal parameters were statistically evaluated using descriptive statistical and ANOVA. The correlation between plaque and periodontal parameters was analyzed by Pearson's correlation coefficient. The results showed an increase in the mean of periodontal destruction (PPD and CAL) and a higher number of sites with severe losses with increasing age. Correlation among percentage of sites with plaque and periodontal parameters (PPD and CAL) were positive but weakly related. The male group showed significantly higher means of CAL than the female. Smokers had significantly higher PPD and CAL means than non-smokers. Aging, smoking habit, male sex, and percentage of sites with plaque were associated with a great increase of periodontal destruction, being important factors in the diagnosis of the periodontal disease in this Brazilian population.
