Objective: The purpose of this cross-sectional study was to evaluate the prevalence of pillar teeth for fixed prostheses in a subpopulation of adult Brazilians. Methods: Panoramic radiographs of a total of 1401 patients, performed between August 2002 and September 2007, were randomly selected from the database of the Radiological Center of Orofacial Images of Cuiabá (CROIF, Cuiabá, MT, Brasil). A total of 1401 radiographs were examined to determine the frequency of pillar teeth for fixed prostheses. The data were collected and tabulated, regarding age, gender and dental group. The statistical treatment analyzed the data about the frequency distribution and chi-square test. The significance level was set at α = 5%. Results: We evaluated 29,467 teeth, and of these, 4,967 (16.8%) were pillars of fixed prosthesis. High prevalence of pillar teeth for fixed prosthesis was observed in female subjects (61.2%) and aged between 46-60 years (49.9%). Upper and lower premolars were the teeth more often involved in rehabilitation, 20.5% and 17.2%, respectively. Dental absences were identified in 24.8% of the sample. Conclusion: The prevalence of pillar teeth associated with fixed prosthesis was 16.8%, being more frequent in upper incisors and premolars of female subjects.
