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.
