Abstract

Purpose: To describe the behavior clinical and pathological features of two cases of odontogenic cyst orthokeratinized. Case description: In case 1, a 17-year-old woman presented hard and painless swelling in the left posterior mandible. Radiographically, a radiolucent area with a radiopaque was observed. A clinical diagnosis of ameloblastoma or odontogenic keratocystic tumor was established. The histopathological examination revealed an orthokeratinized odontogenic cyst. In case 2, a 23-year-old woman presented a radiolucent lesion surrounded by radiopaque halo symmetrically distributed on both partially erupted lower third molars. A clinical diagnosis of bilateral dentigerous cyst (DC) was rended. The histopathological examination showed bilateral orthokeratinized odontogenic cyst. Conclusion: Orthokeratinized odontogenic cyst should be considered in the differential diagnosis of lesions occurring in the jawbones associated with an impacted tooth, particularly those cases simulating dentigerous cyst. In addition, we observed the importance of radiographs taken prior to orthodontic treatment as an important tool in the diagnosis of oral pathologies. Performing routine radiograph is of high clinical value, especially before orthodontic treatment.
