Summary
Secondary retention, or stopped tooth eruption, is diagnosed by infraclusion. While often resolving spontaneously, severe cases may require intervention for retained primary molars.
Area of Science:
- Dentistry
- Pediatric Dentistry
- Orthodontics
Background:
- Secondary retention is the cessation of tooth eruption after initial emergence.
- It primarily affects primary molars and can impact permanent dentition development.
- Understanding its characteristics is crucial for timely intervention.
Purpose of the Study:
- To evaluate the clinical, radiographic, and histological features of secondary retention.
- To assess treatment outcomes for secondarily retained primary molars.
- To identify diagnostic criteria and therapeutic indications.
Main Methods:
- Retrospective analysis of 34 patients with 77 secondarily retained primary molars.
- Clinical and radiographic assessments, including evaluation of infraclusion.
- Histological examination and follow-up on treatment results.
Main Results:
- Infraclusion was the key diagnostic criterion; percussion was unreliable.
- Secondary retention in primary teeth can predispose to similar issues in permanent teeth.
- Spontaneous resolution of occlusal disturbances occurred unless permanent dentition was affected.
Conclusions:
- Infraclusion is the primary diagnostic indicator for secondary retention.
- Early intervention for secondary retention is not always necessary, with spontaneous resolution common.
- Active therapy is reserved for severe cases involving significant malocclusion or successor anomalies.
