Altered anatomy in a case with a buccally impacted maxillary canine tooth
Summary
A submucosal impacted canine was found near the maxillary sinus and nasal cavity in a cadaver dissection. This anatomical finding highlights potential risks during dental procedures in this region.
Area of Science:
- Anatomy
- Oral Surgery
- Maxillofacial Radiology
Background:
- Detailed anatomical dissections of the human maxilla are crucial for understanding complex surgical relationships.
- The proximity of dental structures to the maxillary sinus and nasal cavity necessitates thorough pre-operative assessment.
Observation:
- A dissection revealed a submucosal, labially impacted right upper canine.
- The canine's apex was near the maxillary sinus floor and the inferior nasal meatus.
- A follicular cyst was noted adjacent to the canine's neck, with sinus wall dehiscence.
Findings:
- The impacted canine's root was closely related to the inferior nasal meatus floor.
- Nerves for the canine and incisors were identified within the walls of the maxillary sinus and inferior nasal meatus.
- The maxillary sinus exhibited a superomedial recess adjacent to an enlarged inferior nasal meatus.
Implications:
- This case highlights the intricate anatomical relationships that can influence surgical planning for impacted teeth.
- Understanding these relationships is vital for minimizing risks of sinus or nasal cavity injury during dental procedures.
- Further research into variations in these anatomical structures can improve patient safety in oral and maxillofacial surgery.

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.

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...
