Abstract

The prevalence of the radicular groove on the lateral maxillary incisor was studied for the first time in Russia. The aim of the study was to evaluate the frequency of occurrence of the anomaly, its location, type, and dependence on sex.
Materials and methods.
Cone beam computed tomography (CBCT) scans of 1002 patients (500 females and 502 males), aged 13—85 years, performed in 2017—2023 at the clinic “Alpha-Dentistry” (Ryazan, Russia) were studied to identify the palatal radicular groove of the maxillary lateral incisor.
Results.
The frequency of occurrence of this anomaly is 4.2% (4.6% in females and 3.8% in males). The frequency of detection was 9.5% on the mesial surface, 40.2% on the central surface, and 52.4% on the distal surface.
Conclusion.
The palatal radicular groove is a developmental anomaly that often leads to periodontal diseases and endodontic pathologies. Computed tomography is the main method for its diagnosis.

Key words:

palatine-radicular sulcus, periodontal pocket, cone-beam computed tomography, root canal, diagnostics
