Purpose:
Coronectomy is a well-documented surgical technique for the treatment of high-risk third molars, but the fate of retained roots remains controversial. This case report describes the histologic analysis of retained root fragments.
Patient And Methods:
A 44-year-old man treated with coronectomy of a left mandibular third molar requested the extraction of the retained roots. The patient was asymptomatic and the retained roots were extracted 18 months after coronectomy at the patient's request.
Results:
The extracted roots were histologically evaluated and the results showed the presence of vital pulp tissue.
Conclusion:
Histologic analysis showed that retained roots remain vital after coronectomy.
