A novel root canal filling technique using a resin-based sealer without gutta-percha: a summary of two cases.

OBJECTIVES

Root canal filling is a fundamental step in non-surgical root canal treatment (RCT), required to prevent reinfection or new infection within the root canal system. Traditionally root canal filling uses a sealer in combination with gutta-percha (GP). Here, two cases are presented in which the root canals were filled using only a methacrylic resin-based sealer without GP.

MATERIALS AND

METHODS

Two patients (one male, one female) required RCT - one due to irreversible pulpitis and the other to facilitate a subsequent post-retained protheses. Each RCT was performed according to a standardized procedure, before root canal filling using only methacrylic resin sealer.

RESULTS

Fillings were completed in curved and straight root canals without evidence of apical extrusion. No clinical symptoms or signs of dissolution were observed during follow-up (24 and 12 months in the respective cases).

CONCLUSIONS

Our findings demonstrate the potential applicability of this novel technique for root canal filling using only a methacrylic resin-based sealer without GP.

CLINICAL RELEVANCE: The success of our RCT cases offers evidence to support further clinical studies that compare the outcomes with standard root canal procedures.
