Summary
Ectopic teeth, rare dental anomalies, can occur in unusual jaw locations. This case series highlights their association with pathologies like dentigerous cysts and effective surgical management.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Pathology
- Radiology
Background:
- Ectopic tooth eruption, displacement from the normal dental arch, is uncommon but can occur in various jaw locations.
- While commonly associated with third molars, ectopic teeth can present in rarer sites, necessitating careful diagnosis and management.
Observation:
- This study reviewed ten cases of ectopic teeth managed between 2011 and 2020.
- Ectopic teeth were found predominantly in the antrum (50%) and mandible (40%), with males comprising 80% of cases.
- Dentigerous cysts were the most frequent associated pathology (70%), often presenting with pain and swelling.
Findings:
- Ectopic teeth in rare jaw locations were identified, with a male predominance and a mean age of 23.3 years.
- The antrum and lower mandibular border were the most common sites for these ectopic teeth.
- Dentigerous cysts were significantly associated with ectopic teeth, presenting clinically with pain and swelling.
Implications:
- A high index of suspicion and radiological imaging are crucial for diagnosing ectopic teeth in atypical locations.
- Surgical intervention, often via an intraoral approach, is effective for managing symptomatic ectopic teeth and associated pathologies.
- Further multi-center research is recommended to ascertain the prevalence of ectopic teeth beyond the third molar region.

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...

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...

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...
