Occurrence and distribution of lost molars and furcation defects in a Bulgarian population: A retrospective three-dimensional study

Abstract

Objectives: To identify the ocuurrence, distribution, and factors associated with lost molars and furcation defects in a sample of the Bulgarian population. Material and Methods: The full mouth cone-beam computed tomography of 56 male and 57 female patients, aged between 19 and 84 years, were examined. A comprehensive evaluation was performed on a total of 675 molars—339 in maxilla and 336 in mandible. Associations with variables such as age, gender, and periodontal disease were analyzed. Results: With aging the number of missing teeth and interradicular lesions increased. No significant links between gender and molar loss (p =.64) or gender and furcation involvement (p =.25) was found. Periodontitis was strongly associated with both studied dental problems (p
