RESUMO
The aim of this report is to present the results of a personalised endodontic treatment for an immature molar, using regenerative endodontic procedure (REP) combined with non-surgical root canal treatment (NSRCT), with 7 years of follow-up. The tooth#3 presented combined endodontic pathologies in each root, with different pulpal and periapical status. A REP in the palatal (P) canal and a NSCRT in the mesio-buccal (MB) and disto-buccal (DB) canals were performed. Absence of clinical signs/symptoms and continuous palatal root development with apical closure were observed over 4-years. After 5-years an apical lesion in the MB root was observed. Both MB canals were selectively retreated by completely filling them with TotalFill BC RRM Fast Set putty. After 7-years, the tooth remained functional and the apical lesion was resolving. The palatal root was completely mature. This case report reveals the potential for use of combined treatment approaches for immature multirooted teeth.
