Endodontic management of immature teeth with spontaneous apical closure and periapical lesions: case series and review of the literature.
Spontaneous apical closure in non-vital immature teeth has been rarely encountered and outcome of non-surgical endodontic treatment of related teeth associated with periapical lesions has not yet been adequately elucidated. The aim of this article was to report endodontic management of spontaneous apical closure of infected untreated immature teeth with periapical lesions and to review previously proposed mechanisms for the development of spontaneous hard tissue barrier. Three patients were referred at different time intervals to the endodontic clinic for treatment of their maxillary anterior incisors with acute or chronic apical periodontitis. Dental histories indicated that related teeth had been subjected to trauma approximately 12-18 years previously. Radiographically, the involved teeth exhibited incomplete root formation with spontaneous apical closure and were associated with an apical radiolucency. After biomechanical preparation, calcium hydroxide paste was applied and was changed once or twice within 3 months. All canals were then filled with gutta-percha and AH Plus and the follow-up period was 16-50 months; both clinical and radiographic examinations revealed adequate function, the absence of clinical symptoms and significant healing of the periapical radiolucency.
