RESUMO

The aim of the present investigation was to perform a radiographic analysis of patients in Periodontal Maintenance from the Department of Periodontology Graduation - Dentistry College University of São Paulo. Complete sets of periapical radiographs provided data for alveolar bone loss percentage which was correlated to age, smoking status, gender, arches, teeth group and proximal sites. The sample was consisted of 27 male and 53 female subjects with age from 16 to 84 years old (mean 48,3 years). 1120 radiographs (1970 teeth) were digitalized and analyzed with the software Image Tool ® (University of Texas - Health and Science Center). The criteria used to consider bone loss was when the distance from the cement enamel junction to the apex was greater than 2 mm. Two examiners, intra and inter calibrated (p <0,0001) were responsible for taking the radiographic measurements of bone loss. The mean bone loss of the sample was 20,61%. The prevalence of bone loss was greater in smokers. Nevertheless, there was no difference between male and female (p <0,0005). The distal surface and the superior arch had the greatest bone loss, as well as the group of incisors and superior molars. The age group of 45- 54 had the highest scores for bone loss. Smoking and group age from 45 to 54 years are two independent variables that may characterize those individuals most prone to alveolar bone loss.
