The application of laser in endodontic therapy has been extensively studied. In few cases both periodontal and pulpal disease present simultaneously and pose a significant challenge in diagnosis, treatment planning, as well as healing of the endoperio lesion. This study aims at orderly treating endo-perio lesions with the help of diode laser. The case reports deal with true endodontic and combined endo-perio lesion in maxillary incisors. True endodontic lesion in 11 was treated with root canal obturation after disinfection with diode laser. Combined endo-perio lesion in 21 was treated with root canal obturation assisted by diode disinfection, scaling, and laser curettage and cleaning of periodontal pocket. The procedure resulted in resolution of periodontal pocket depth after 2 months. One year review of both cases showed healing of periapical lesion and maintenance of periodontal health. Diode laser is an excellent tool in handling soft tissues, gingiva, and periodontium due to less tissue shrinkage, less intraoperative time, and reduced postoperative discomfort. Laser disinfection of root canals assists in healing and prognosis in complicated situations. The use of lasers may lead to developing better and predictable treatment protocol for endodontic periodontal lesions.
