Summary
A rare case of dilated odontome, a severe form of dens invaginatus, was found in a woman's mandible. Surgical removal and analysis confirmed this unusual dental anomaly.
Area of Science:
- Dentistry
- Oral pathology
- Radiology
Background:
- Dens invaginatus is a developmental anomaly of teeth.
- Dilated odontome represents the most severe manifestation of dens invaginatus.
- Mandibular molar region involvement is exceptionally rare.
Observation:
- A 28-year-old female presented with a unique ringlike radiopaque lesion on panoramic radiography.
- The lesion was associated with the mandibular right third molar.
- Computed tomography (CT) scans indicated an intraosseous circular radiopaque formation.
Findings:
- Surgical extraction (alveotomy) of the affected structure was performed.
- Histopathological examination of the removed tissue confirmed the presence of a dilated odontome.
- Analysis of surrounding soft tissue showed no other abnormalities.
Implications:
- This case highlights the importance of considering rare dental anomalies in differential diagnoses.
- Accurate radiographic interpretation and advanced imaging are crucial for identifying such conditions.
- Understanding dilated odontomes aids in appropriate surgical and diagnostic management.

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.
