[Case of familial hypodontia]

Area of Science:

• Dentistry
• Genetics
• Human Biology

Background:

• Hypodontia, the congenital absence of teeth, is a common dental anomaly.
• Understanding its genetic basis is crucial for diagnosis and management.

Observation:

• A family presented with multiple instances of missing teeth.
• The mother exhibited hypodontia, lacking 12 teeth.
• Her children, a 14-year-old daughter and a 12-year-old son, displayed severe forms of hypodontia.

Findings:

• The daughter presented with oligodontia, missing 20 permanent teeth.
• The son exhibited ateleblastodontia, lacking 14 permanent teeth.
• These findings suggest a familial pattern of severe tooth agenesis.

Implications:

• This case series underscores the importance of genetic counseling for families with hypodontia.
• Further research into the genetic factors influencing tooth development is warranted.
• Early identification and management of hypodontia can prevent functional and aesthetic issues.
