Abstract

PURPOSE: This study was intended to estimate the prevalence of cemento-osseous dysplasia (COD) in the Korean population and to assess the clinical and radiographic characteristics of this condition.
MATERIALS AND METHODS
Panoramic radiographs from 10,646 patients (4,982 males and 5,664 females, age range from 6 to 91 years) were reviewed for evidence of COD. Their demographics, clinical characteristics, and radiographic features were retrospectively assessed.
RESULTS
Of 10,646 panoramic radiographs, 33 radiographs (0.31%) exhibited evidence of COD. The prevalence of COD increased to over 1% in women over 40-years old. Of these 33 patients, 16 had florid cemento-osseous dysplasia (FCOD) and 17 had focal COD. Due to the multiplicity of FCOD, a total of 63 COD lesions were assessed. These lesions were most common in the mandibular molar area. Most of the COD lesions examined (61.9%) were less than 10 mm and the majority (82.5%) showed radiopacity.
CONCLUSION
COD has a predilection for the mandibular molar area of middle-aged and older women.
