Early hypercementosis and arrested dental eruption: heritable multiple ankylodontia
Journal of Craniofacial Genetics and Developmental Biology
|January 1, 1984
Summary
This study identifies a rare genetic condition causing arrested tooth eruption, characterized by hypercementosis and bony ankylosis. The severe dental malocclusion affects multiple family members, suggesting a dominant inheritance pattern.
Area of Science:
- Dentistry
- Genetics
- Oral Pathology
Background:
- Tooth eruption is a complex process crucial for occlusion.
- Disorders of tooth eruption can lead to significant dental malocclusion.
- Genetic factors play a role in tooth development and eruption patterns.
Observation:
- Four family members presented with arrested posterior permanent tooth eruption.
- Associated radiographic findings included hypercementosis, reduced periodontal ligament space, and bony ankylosis.
- The condition resulted in severe dental malocclusion.
Findings:
- Arrested tooth eruption is linked to hypercementosis, reduced periodontal ligament space, and bony ankylosis.
- The observed dental malocclusion appears to follow an autosomal dominant inheritance pattern.
- This familial aggregation suggests a specific genetic etiology.
Implications:
- Understanding this condition aids in diagnosing and managing rare dental anomalies.
- Genetic counseling may be beneficial for affected families.
- Further research into the specific genes involved could reveal novel pathways in tooth eruption and bone biology.
