Keratocystic odontogenic tumor is derived from the proliferation of residues of the dental lamina. Keratocystic odontogenic tumors have high recurrence rate from 0% to 62%, depending on the locations and types of treatment. The controversy still exists about treatment methods ranging from simple curettage to highly invasive en bloc resection. Furthermore, there is no consensus on the most effective surgical technique. We report the first case of removal via endonasal endoscopic approach for a huge, expansile keratocystic odontogenic tumor in the maxillary sinus extending to contralateral central incisor.

Pathological fractures after jaw cyst surgery are rare clinically but are a serious complication. Once a pathological fracture occurs, treatment time and economic costs increase, and doctors face difficulty in handling it. This article reports a case of a patient with mandibular pathological fractures after multiple odontogenic keratocyst surgery of the jaw.

Objectives: This study aims to evaluate the changes in the mandibular canal following the treatment of large odontogenic keratocysts through decompression and curettage, providing a theoretical basis for sequential treatment.

Methods: Twenty patients were selected for each decompression and curettage treatment of large odontogenic keratocysts in the mandible. Postoperative follow-up with was conducted every three months, during which cone beam computed tomography (CBCT) scans were performed.

A dentigerous cyst (DC) is the most common developmental cystic lesion of the jaws. Histologically, these cysts derive from the odontogenic epithelium that includes the reduced enamel epithelium, epithelial cell rests of Serres, and epithelial cell rests of Malassez. Radiographically, DCs are usually presented as well-defined radiolucencies associated with the crown of an unerupted tooth at the level of the cementoenamel junction (CEJ).

Special care is required for the management of jaw lesions in pediatric population. The following article describes the decompression technique as the least aggressive approach for the management of pediatric mandibular odontogenic keratocyst. A custom-made acrylic splint was fabricated around teeth, and it was attached to a piece of Foley's catheter to be used as a decompression port.

Background: N6-methyladenosine (m6A), the most abundant internal RNA modification in mammals, plays a critical role in many forms of cancer. Methyltransferase-like 3 (METTL3) serves as the main catalytic subunit of the m6A writer and plays a role in the progression of head and neck squamous cell carcinoma. To date, the role of METTL3 in odontogenic lesions has never been investigated.
