Pulpectomy using mineral trioxide aggregate of a nonvital primary molar with no permanent premolar successor

Physiological root resorption is a known phenomenon for deciduous teeth with uncertain etiologic factors. The initiation of root resorption could be due to the injury or the infection of the pulp. The physiological, esthetic, and functional consequences of treating primary teeth without permanent successors make it a unique challenge. The aim of this article was to present the treatment, and long-term follow-up of a case in mineral trioxide aggregate (MTA) was used in the pulpectomy of a nonvital primary molar with no permanent successor in a 14-year-old child. The treatment was root canal treatment and total obturation using MTA. Follow-up examinations were done and showed a radiographic healing of the periapical radiolucency and resorption of mesial root. Furthermore, the tooth was asymptomatic and clinically functional.
