Root canal filling with neomta plus in second primary molar teeth with missing successor: twenty-four months of follow-up

Abstract

Hypodontia of the mandibular second premolar teeth is one of the most frequent anomalies of tooth development, which reveals a unique hardship for clinicians. Retaining the primary second molars helps to maintain arch integrity until facial growth is complete. This case series investigates the potential improvement and longevity of retained primary mandibular second molars obturation of the root canal system using a mineral trioxide aggregate when successors are missing. Neo MTA Plus (Avalon Biomed Inc, Bradenton, FL) recently introduced calcium silicate-based cement that may have some potential as a root canal obturating material. Nevertheless, no study using Neo MTA Plus as a root canal filling material was found in the literature. Five female patients with a decayed, necrotic second primary molar tooth without a successor were selected and performed a root canal treatment with Neo MTA Plus. Patients were scheduled for clinical and radiographic evaluation at 6, 12, 18, and 24 months. They were followed up for twenty-four months. According to the present study, it can be concluded that NeoMTA Plus maybe a proper material for use in the root canal treatment of primary molars with a missing successor.
