Usage of white mineral trioxide aggregate in a non-vital primary molar with no permanent successor

The aim of this study was to present the treatment and long-term follow-up of a case in which white mineral trioxide aggregate (WMTA) was used in the pulpectomy of a non-vital primary molar with no permanent successor. The physiological, aesthetic and functional consequences of treating primary teeth without permanent successors makes this a unique challenge. In the present case, WMTA was used in the pulpectomy of a primary molar with no permanent successor in an 8-year-old child. The treatment was considered successful. Follow-up examinations showed that root resorption in the mesial root surface, with no infra-occlusion or ankylosis 36 months after treatment. WMTA may be considered as an alternative pulpectomy material for non-vital primary teeth with no permanent successors, although long-term clinical studies are still needed.
