Abstract

Although periapical inflammatory lesions are usually resulted by infection in the root canal system, this rare case showed that a periapical lesion related to an infected tooth may cause pulpal necrosis in adjacent intact tooth, with no history or clinical signs of caries, disease, trauma or developmental anomaly. This case also suggests that the periapical lesion can be treated conservatively, without surgical intervention. Furthermore, this case highlights the importance of prompt treatment of apical periodontitis before the lesion becomes extensive as well as follows up of large lesions.

  Figure 1 (a) Preoperative radiograph showing a large periapical lesion with loss of lamina dura surrounding the mesial root of lower first molar; (b) Nonsurgical endodontic retreatment was carried out for involved molar but sign/symptoms did not resolve; (c) Pulp Vitality test revealed that the intact adjacent premolar was nonvital and nonsurgical endodontic treatment was carried out; (d, e) Six- and 12-month follow-up radiographs showing gradual bone healing; (f) Two-year follow-up radiograph reveals complete bone healing.
