Summary
Dentigerous cysts, common jaw cysts, rarely occur in the maxilla. This study details an unusual case of a dentigerous cyst in the maxillary sinus linked to an impacted third molar.
Area of Science:
- Oral and Maxillofacial Surgery
- Odontogenic Cysts
- Radiology
Background:
- Dentigerous cysts are the second most frequent odontogenic cysts, representing 15% of all true jaw cysts.
- These cysts predominantly affect the mandible, with a rarer incidence in the maxilla, often linked to impacted mandibular third molars.
- Maxillary sinus involvement by dentigerous cysts, especially with impacted third molars, is an uncommon clinical presentation.

01:15Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
