A 12-month follow-up of primary and secondary root canal treatment in teeth obturated with a hydraulic sealer

Abstract

Objectives This randomized, controlled, pilot study assessed the outcome of non-surgical primary/secondary root canal treatments either with a novel bioactive sealer and the single-cone technique or with gutta-percha, zinc oxide-eugenol sealer (ZOE), and warm vertical compaction. Materials and methods Sixty-nine patients were randomly divided into two groups that were treated using the single-cone technique with BioRootTM RCS (Septodont) (BIO group) or warm vertical compaction with gutta-percha and ZOE sealer (PCS group). Two subsamples (BIOAP and PCSAP) comprised the cases with apical periodontitis. Treatment was undertaken by four residents using a standardized instrumentation and disinfection protocol. The periapical index (PAI) was recorded, and clinical and radiographic follow-up performed at 1, 3, 6, and 12 months. Treatment success was assessed according to “periapical healing” and “tooth survival”. The test for the equality of proportions, t tests for the equality of means, and non-parametric K-sample tests for the equality of medians were applied when appropriate. Results The survival rate was similar in the BIO and PCS (p = 0.4074) and the BIOAP and PCSAP groups (p = 0.9114). The success rate was higher in the BIO groups, but not statistically significant (p = 0.0735). In both BIOAP and PCSAP groups, a progressive decrease in the PAI was observed. Conclusion At 12 months, both techniques showed reliable results. Further studies and longer follow-ups are needed. Clinical relevance This study documents the feasibility of using a bioactive sealer in conjunction with the single-cone technique to obturate the root canal and obtaining a predictable outcome.

Heating stability, physical and chemical analysis of calcium silicate‐based endodontic sealers

“…Positive outcomes after root canal treatments are closely associated with the quality of the final root filling, since both the root canal sealer and gutta‐percha points should ideally provide a hermetic sealing against bacteria and body fluids, ensuring periapical health (Schilder 2006, Bardini et al . 2020). Several techniques and materials are available for this purpose (Gilbert et al .…”

Porosity Distribution in Single Cone Root Canal Fillings Performed by Operators with Different Clinical Experience: A microCT Assessment

“…It has been demonstrated previously that the clinical experience of the operator has a substantial impact on the quality of the endodontic procedures and clinical outcome [12,34]. It has been shown that the lowest root-canal obturation quality was observed among undergraduate dental students, and gradually improved over a period of time after graduation and acquisition of clinical experience [34,35]. Finally, the best results and the highest success rates were achieved when endodontic treatment was performed by an ED [36].…”

Microcomputed Tomographic Assessment of the Single Cone Root Canal Fillings Performed by Undergraduate Student, Postgraduate Student and Specialist Endodontist

“…Previous clinical studies revealed high success rates of endodontic treatment when root canals were obturated by specialists endodontists using SC technique with a hydraulic calcium silicate-based sealer: Chybowski et al (2018) reported the success rate up to 90.9% after an average follow-up of 30.1 months [ 24 ], while the study conducted by Zavattini et al (2020) demonstrated success rates varying from 84% to 90% [ 25 ]. A slightly lower success rates were revealed in a clinical study by Bardini and co-authors in which all treatment procedures, including root canal obturation using SC technique, were performed by postgraduate students in endodontology program: the complete healing rates over a 12-month period has reached 76.92% [ 51 ]. However, more clinical studies are needed to confirm the impact of the operators experience on the long-term clinical results, when SC root canal obturation technique is used.…”
