Clinical outcomes of nonsurgical root canal treatment using NeoSealer Flo and Endosequence BC Sealer: A retrospective analysis with short-term follow-up

Sealers are an important component in root canal obturation to provide the seal of the root canal system. In recent years, there has been an increase in the use of hydraulic silicate sealers, commonly referred to as bioceramic sealers, due to their many advantageous properties. NeoSealer Flo (NS; Avalon Biomed USA, Houston TX) is a recently introduced premixed bioceramic sealer. There is limited evidence on its properties and clinical performance. Therefore, the purpose of this study was to evaluate the outcome of root canal treatment using NS in a sealer-based obturation technique.

The records of patients in a private practice between 2017 and 2022 were analyzed to identify both initial and retreatment cases obturated with either EndoSequence BC sealer or NS using sealer-based obturation with a minimum of one-year follow-up. Treatment outcome between NS and BC was compared with chi-square test. Logistic regression was used to identify additional prognostic factors.

Six hundred and eighty-seven teeth met the inclusion criteria for the study. The success rate of cases obturated with BC was 94.9% and 96.5% for the cases obturated with NS. No statistically significant differences were found between the two sealer types. Presence of a periapical radiolucency or periapical radiolucency > 5.00 mm were statistically significant prognostic factors.

Endodontic treatment using BC or NS with sealer-based obturation method is a viable treatment option.

Root canal obturation with bioceramic sealers, such as NeoSealer Flo and Endosequence BC sealer, provide favorable clinical outcomes.
