Summary:

Aim is to analyze the dimensional characteristics of the width of the periodontal fissure in the teeth of the upper and lower jaws with increased tooth abrasion in adults. Material and Methods. 204 people of both sexes aged 22 to 60 years were served as the object of the study. Using cone beam computed tomography, the width of the periodontal fissure was studied at the level of transition of the upper third to the middle third of the root, at the level of transition of the middle third of the root to the lower third, and at the level of the apex of the tooth root. In the upper molars, the measurements were performed at the palatine root, in the molars of the lower jaw — at the distal root. Results. The dimensional characteristics of the width of the periodontal fissure on both jaws statistically significantly increase from the first period of adulthood to the second in persons of both sexes: in men at the level of the upper third of the root by 12.5-96.3%, the middle third —11.8-78.6%, tops of the tooth root —22.2-106.7; in women —by 2.4-65.8, 3.0-22.0and 19.1-93.6%, respectively. Conclusion. The results of the study indicate that the width of the periodontal fissure is not the same in different parts of the root, varies depending on the functional load and does not depend on the group affiliation of the tooth. The width of the periodontal fissure at the level of transition of the upper third of the root to the middle third, the middle third of the root to the lower third and in the region of the apex of the root in the teeth on the lower and upper jaw, statistically significantly increases from the first period of adulthood to the second in both men and women.
