Summary
Pre-Eruptive Intracoronal Resorption (PEIR) is a rare dental condition. This case report details successful vital pulp therapy and gingivectomy for a symptomatic tooth diagnosed with PEIR.
Area of Science:
- Dentistry
- Endodontics
- Oral Pathology
Background:
- Pre-Eruptive Intracoronal Resorption (PEIR) is a rare condition characterized by internal tooth resorption before eruption.
- Early diagnosis and intervention are crucial for preserving tooth vitality.
Observation:
- A 12-year-old female presented with spontaneous pain in a partially erupted tooth #31.
- Radiographic evaluation, including CBCT, revealed a radiolucent area indicative of PEIR, with intact enamel and symptomatic irreversible pulpitis.
- Histological examination of excised granulation tissue confirmed acute and chronic inflammation.
Findings:
- Vital pulp therapy combined with gingivectomy was performed on tooth #31.
- The tooth remained asymptomatic post-procedure with continued root development.
- A positive electric pulp test response was noted 3.5 years after treatment, indicating pulp vitality.
Implications:
- This case highlights the successful management of PEIR using conservative endodontic treatment.
- Preserving tooth vitality in PEIR cases is achievable, promoting normal root development and function.
- Conservative management of PEIR can be a viable alternative to extraction, especially in young patients.
