Summary
Tooth intrusion, a common infant injury, often affects upper incisors. While spontaneous re-eruption is common, some teeth experience complications like necrosis or resorption, though pulp health is often maintained.
Area of Science:
- Pediatric Dentistry
- Dental Traumatology
- Oral Health
Background:
- Tooth intrusion, the displacement of a tooth into its socket, is the most frequent dental trauma in early childhood.
- Understanding the outcomes of intruded primary teeth is crucial for effective management and long-term oral health.
- This study focuses on the sequelae of intruded primary teeth, particularly central incisors, in infants.
Purpose of the Study:
- To evaluate the clinical outcomes and sequelae of tooth intrusion in primary teeth.
- To analyze the rate of spontaneous re-eruption and associated complications.
- To assess the long-term pulp vitality and root development following intrusion injuries.
Main Methods:
- A prospective study monitoring 16 patients with 22 intruded primary teeth over 3 to 36 months.
- Data collection included patient demographics, affected teeth, treatment approach, and clinical outcomes.
- Clinical and radiographic assessments were used to evaluate re-eruption, pulp status, and root development.
Main Results:
- The majority of intruded teeth (91%) were upper central incisors, with 56.25% of affected patients being male.
- Spontaneous re-eruption occurred in 42.5% (total) and 47% (partial), with no re-eruption in 10.5% of cases.
- Complications included necrosis (23%) and root resorption (33%), while 57% of teeth maintained healthy pulps regardless of re-eruption status.
Conclusions:
- Spontaneous re-eruption is a frequent outcome for intruded primary teeth, but complications like necrosis and resorption can occur.
- Monitoring intruded primary teeth is essential to manage potential sequelae and preserve pulp vitality.
- Despite trauma, a significant proportion of intruded primary teeth maintain healthy pulps, highlighting the importance of conservative management.
