Purpose: Studies reported controversial results about prognosis of root resection with 0%-38% failure rate. The purpose of this study is to consider clinical efficacy of root resection.Materials and Methods: This study reported three cases of root resection which were performed on different sites. In first case, lower right first molar showed pus discharge and 7mm of probing pocket depth. It was diagnosed as fracture of mesial root. Hemisection of mesial root was performed In second case, upper right first molar showed severe bone loss on disto-buccal root and 7mm of probing pocket. Resection of disto-buccal root was performed In third case, lower left second molar showed severe bone loss on distal root including apex and 15mm of probing pocket depth. Hemisection of distal root was performed．Result: In these three cases of root resection, compromised molars were treated successfully and conserved.Conclusion: Root resection is a successful procedure treating compromised multi-rooted teeth and conserving teeth when proper case selection is performed.
