Indonesian Journal of Dentistry 2006; Edisi Khusus KPPIKG XIV: 62-68 An inadequate endodontic treatment may affect the root canat system and spread beyond its apical foramina that elicit periodontal tissue developing into abcess, granuloma and radicular cyst. Periapical lesions can be treated with non surgical endodontic treatment using calcium hydroxide dressing. This case study is reporting teeth 11 with periapical lesions and infection. Evidence of a clinical healing and radiographic assessments were followed by a non surgical endodontic therapy. Successful treatment outcome is related to the elimination of infection agents from the root canal. This can activate a stimulation zone to promote regeneration. Calcium hydroxide used as a root canal dressing may promote alkalinity at the adjacent tissue, create favourable enviromental condition in which hard tissue formation can occur, interfere the bactericidal activity, increase mineralization, and induce healing.

Indonesian Journal of Dentistry 2006; Edisi Khusus KPPIKG XIV: 69-73 Evidence of an internal root resorption is quite rarely found in permanent teeth. In most cases it is usually asymptomatic and detected only by radiographic screening. The appearance in a radiographic view seems uniform, i.e. round to oval shaped radiolucent enlargement of pulp dental space. Trauma was Commonly recognized as one of the initiating factors of intemal root resorption. This case report of endodontic management will specifically focus on a maxillary left second premolar with internal resorption due to chronic pulpal inflammation. A common failure in performing a hermetic sealing of the root canals might depend on the complexity of anatomy of its root canals. Therefore, a modification of obturation techniques is needed. The report described a combination of a cold lateral condensation technique and a warm vertical condensation technique to improve the hermetic obturation. The result of this study shows that a combination technique could be used as an alternative technique in obturating the canals with an intemal root resorption.
