Evaluation of the frequency and characteristics of hypercementosis in the Turkish population with cone-beam computed tomography

Abstract

Aims: The aim of this study was to evaluate the frequency and characteristics of hypercementosis in the Turkish population using cone‑beam computed tomography (CBCT).

Settings and Design: A retrospective study was performed using CBCT (I-CAT Vision TM Imaging Science International) in 1263 patients admitted to the Faculty of Dentistry at the University of Dicle (Diyarbakir, Turkey) between January 2013 and January 2015.

Subjects and Methods: A total of 1152 patient and 29,606 teeth were evaluated with CBCT. The age, gender, location (left vs. right side, maxillary vs. mandibular teeth, incisors, premolars, and molars), and missing teeth were recorded for all patients.

Statistical Analysis Used: The Pearson Chi‑squared test was used to determine the potential differences.

Results: Hypercementosis was observed with a frequency of 2.4%. Of these, 18 of 28 (64.3%) had only 1 tooth with hypercementosis and 10 (35.7%) had more than 1 tooth. It was identified in 42 of the 29,606 teeth examined (0.14%). The lesion was found in 2.47% (n = 14) of females and 2.38% (n = 14) of males. The lesion was detected in 28 molars and 14 premolars, but hypercementosis was not detected in incisors. Of the 42 teeth, 12 (28.6%) maxillary and 30 (71.4%) mandibular teeth were associated with hypercementosis. Of the 28 cases, 20 (59.0%) were unilateral and 8 (41.0%) were bilateral. Of the 20 unilateral cases, 12 (69.6%) were on the right and 8 (30.4%) were on the left side.

Conclusions: In our study, the prevalence of hypercementosis has been found 2.4% in the Turkish population. Besides, the lesion has been found more in the mandible than the maxilla, in the molars than the premolars and in the unilateral distribution than the bilateral distribution.
