Inflammatory odontogenic cyst in a child: case report

Odontogenic cysts arise from epithelium residuals forming the tooth. When they are infected, they can reach large sizes and cause bone resorption in the surrounding bone.A 9-year-old girl who was brought to Department of Pediatric Dentistry was referred to the Department of Oral and Maxillofacial Surgery due to a suspicion of a cystic lesion in the premolar region of the patient's right lower jaw as a result of clinical and radiographic examinations. Fine needle aspiration biopsy was performed after the patient's cone beam computed tomography was taken, and the specimen was sent to pathology. Histopathologically, cyst with suppurative inflammation was diagnosed. Then, the treatment was planned and marsupialization method was chosen considering the size of the lesion, the age of the patient, and the presence of impacted tooth in the region concerned.As a result of a 14-month follow-up, the radiography of the patient showed that although the cyst was not enucleated, radiolucency in the related region disappeared and the tooth number 45 erupted to the oral cavity. In this way, it was considered that marsupialization treatment was a successful method.
