Summary
Congenital tooth agenesis, particularly of second premolars, necessitates preserving primary teeth. This approach delays definitive prosthetic decisions and shows high survival rates, though complications like caries can occur.
Area of Science:
- Dentistry
- Oral Surgery
- Pediatric Dentistry
Background:
- Congenital tooth agenesis is a common dental anomaly.
- Second premolars are most frequently affected, excluding third molars.
- Primary tooth preservation is a strategy to maintain space and postpone prosthetic treatment.
Purpose of the Study:
- To review the literature on the outcomes of preserving primary second premolars in cases of congenital agenesis.
- To assess the survival rates and identify potential complications associated with this management approach.
Main Methods:
- A comprehensive literature review was conducted.
- Studies focusing on the preservation of primary second premolars in patients with congenital tooth agenesis were analyzed.
- Pathology-free survival rates and complication types were extracted and synthesized.
Main Results:
- Pathology-free survival rates ranged from 82% to 89% over 5 to 13 years.
- Common complications included caries, gingivitis, infraocclusion, and root resorption.
Conclusions:
- Preserving primary second premolars is a viable option for managing congenital agenesis.
- This approach offers favorable long-term outcomes but requires monitoring for potential biological complications.
