Calcifying Odontogenic Cyst – A Three-Dimensional Radiological Evaluation By Cone Beam Computed Tomography, Karthik Rajaram Mohan, Saramma Mathew Fenn, Ramachandra Reddy Venkatesha

International Arab Journal of Dentistry

Calcifying odontogenic cysts is an odontogenic cyst that gives rise to painless swelling which expand and occasionally perforate bone. Most of them are between 2 to 4 cm in diameter. Approximately 75% occur in anterior canine-incisor region. The highest incidence of occurrence is between 10 and 29 years. Radiographically they appear as well-circumscribed, unilocular cystlike areas with scattered radiopacities which range from mere flecks to large masses. The related tooth usually gets displaced. Radiopaque flecks occur in radiographic features of some lesions which undergo osteolysis during their development. They occur as a result of dystrophic calcifications in long standing chronic …
