Estimation of the length of maxillary molars and premolars and the distance from the apexes of these teeth to the maxillary sinus according to cone-beam computed tomography (CBCT) in different age groups

Abstract

To plan dental interventions on the upper jaw teeth, a doctor needs to know the relationship of the teeth apexes and maxillary sinus. Measurement of these parameters using a cone-beam computed tomography (CBCT) allows to plan the interventions precisely to minimise complications.Аim. It was to evaluate the length of the molars and premolars of the upper jaw and the distance from the apexes of their roots to the maxillary sinus floor according to cone-beam computed tomography (CBCT) in different age groups.Material and methods. We analysed CBCT data of patients in three age groups: young, middle and elderly. On the upper jaw, the length of molar and premolar roots in the examined contingent is the same in all age groups and is within 18-19 mm and 20-21 mm, respectively.Results. The smallest distance to the maxillary sinus was recorded in the second and third molars in the young and middle age group and in the second premolar region in the young age group. With age, there is a significant increase in the distance to the sinus in the molar zone.
