OBJECTIVE: To analyze the causes of root fractures by examining fractured roots histologically.
METHODS: Fractured roots were sectioned for microscopic analysis in conventional histological ways.
RESULTS: 1. Among 18 roots cut transversely were 14 flat roots with 2 canals, 2. most of the fractures passed along incremental line in dentine, 3. of the longitudinally sectioned roots, areas of marked resorption were visible on the dentine within the fractures of apical third, and 4. repairs of both soft and hard tissues were observed in the fracture spaces.
CONCLUSION: The fractures of roots were associated with morphology of roots and incremental lines in dentine. The repair and cure of fractured roots were not impossible.
