The regenerative endodontic procedure (REP) is considered a viable treatment option for immature teeth with necrotic pulp and\nperiapical radiolucency which can facilitate continued root formation. In this report, an immature necrotic mandibular molar\nreceived REP in three appointments wherein chemomechanical debridement was performed with a sequential application of\nnonsetting calcium hydroxide (in the whole canal) and triple antibiotics paste (in the rootâ??s middle third) dressings in the first\nand second appointments, respectively. In the third appointment, blood clots were created in the root canals. MTA was placed\nover the blood clots and the tooth was restored with a composite filling and stainless-steel crown. Recall appointments were\nperformed for two years where the tooth was deemed asymptomatic clinically and a complete root formation with significant\nperiapical healing was evident radiographically. More cases are required to warrant the feasibility of this disinfection protocol.
