Retrospective evaluation of cone-beam computed tomography findings of odontogenic cysts in children and adolescents.

Abstract

Odontogenic cysts develop from the epithelium of dental structures and generally grow slowly. In children and adolescents, cysts usually grow faster than adults and require much knowledge for diagnoses and treatments. This study aimed to determine the diagnosis and treatment of odontogenic cysts in different age groups by evaluating the type of lesions, age, gender, and anatomical distribution of odontogenic cysts seen in children and adolescents by cone-beam computed tomography. A total of 42 odontogenic cysts (radicular, dentigerous cyst, and odontogenic keratocyst) were determined in children and adolescents aged 7-18 years. Cone-beam computed tomography images of odontogenic cysts were analyzed in terms of types, age, sex, anatomical location, height, width, depth, scalloped borders, lesion shapes, tooth displacement, root resorption, and association with an unerupted tooth. There was a significant correlation between odontogenic cyst types and age groups, scalloped borders, lesion shape, tooth displacement, root resorption, and association with an unerupted tooth. When odontogenic cysts seen in children and adolescents are examined with cone-beam computed tomography, the radicular cyst was the most common form and was predominated in the 13-18 years age group and in boys. Differences in terms of scalloped borders, lesion shape, tooth displacement, root resorption, and association with unerupted teeth were noticed. The knowledge of the distribution and properties of odontogenic cysts in pediatric patients will help diagnose the lesions during clinical and radiological examinations and make appropriate treatment planning.
