Dentigerous cysts are benign maxillary odontogenic cysts associated with the crown of an unerupted tooth. They can expand the cortical bone to such an extent that they cause displacement of teeth and root resorption in the adjacent teeth. The purpose of this report was to describe the clinical case of a dentigerous cyst in a mandibular permanent molar of a 6-year-old child. The cyst caused the displacement of the bud of the permanent second molar and root resorption of the primary second molar. The cyst was treated by: (1) mucous fenestration using an erbium laser: (2) drainage of the fluid content; and (3) curettage of the bone cavity. The injury was successfully resolved in just 5 months with: (1) bone regeneration; (2) the repositioning of the displaced bud; and (3) correct eruption of the affected tooth.

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).

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.

Purpose: This report aims to present an interdisciplinary approach to diagnosing and treating a case of Common Variable Immunodeficiency (CVID), an inborn error of immunity, resulting in successive complications following a third molar extraction procedure.
Case Presentation: The patient, a 37-year-old Caucasian female, sought a specialist for the extraction of an impacted lower third molar associated with dentigerous cyst. Due to the possibility of mandibular fracture, a bone fixation system was used in the region.

Article Synopsis
- Odontogenic cysts can be treated aggressively through enucleation or conservatively through techniques like cyst decompression.
- Cyst decompression helps to alleviate pressure within the cyst, leading to its shrinkage and potentially avoiding more invasive treatments.
- The article details a case study of an 8-year-old boy with an infected odontogenic cyst who underwent a decompression technique for treatment.
