This case report illustrates determination of prognosis and immediate resection carried out, before completing the endodontic therapy, during the surgery employed for managing a nonperiodontal problem. This case showed external pressure resorption in the distobuccal root of maxillary second molar caused by the impingement of impacted third molar. Extraction of third molar was decided when healing was not seen, despite initiating endodontic therapy in second molar. Following elevation of flap and extraction of third molar, the poor prognosis due to severe bone loss around the resorbed root was evident. But due to strategic value of second molar, it was found beneficial to employ resection. Therefore, immediate resection was carried out in the same surgical field before the completion of endodontic therapy. This prevented the need for another surgical entry with its associated trauma to carry out resection separately later. Resection followed by the completion of endodontic therapy and full crown assisted in salvaging the remaining functional portion of the tooth and prevented the occurrence of distal extension with its potential drawbacks.
Introduction : Hemisection may be a valuable form of treatment for molar teeth when caries has progressed to the furcation, or where there is an extensive carious lesion extending subgingivally in one area of the root, making it impossible to place an adequate restoration in that area and the root is considered unrestorable. Case Presentation : When one of the roots of a multirooted teeth is beyond the scope of restoration, it becomes imperative to remove the diseased root. This case report is about the use of hemisection procedure which was carried out to salvage the mesial portion of the mandibular right first molar.
Conclusion :The use of the procedure of hemisection can successfully eliminate the need for extraction of the whole tooth if only a part of it is unrestorable.
Self-introduced foreign object by an adult into the root canal of a lower incisor is seldom reported in the endodontic literature. This case report describes a self-introduced unusual foreign body and its retrieval from the root canal of lower left lateral incisor. A persistent sinus tract resistant to calcium hydroxide intracanal medicament was then successfully treated with the use of triple antibiotic paste. Postendodontically, nonvital bleaching and composite resin restoration was used to restore the form, function and esthetics of the tooth in a conservative manner.

Pulpal pain does not refer to an endodontically treated tooth. Nevertheless, such a potential may exist based on a learned phenomenon due to previous treatment experiences but is rarely reported. Further, it is seldom reported to occur with atypical features. This case report is on a patient who was presented with pain in endodontically treated lower first molar (36) and recommended to undergo retreatment. However, endodontic treatment in 26 relieved the pain showing occurrence of referred pulpal pain in 36. But due to atypical referral and unknown endodontic status in 36, only uneventful follow-up confirmed the retrospective diagnosis of referred pulpal pain in 36. Pulpal pain can refer to an endodontically treated tooth based on learned phenomenon. Such a referral can also occur with atypical features and pose a diagnostic dilemma. Therefore, referred pulpal pain should be considered in the differential diagnosis of pain in an endodontically treated tooth.
