Success Rate of a New Calcium Silicate Root Canal Sealer
Objectives: The aim of this non randomized clinical trial is to compare the success rate of root canals obturated using either a calcium silicate root canal sealer in combination with a single cone technique or with resin based sealer in combination with vertically condensed gutta-percha.
Methods: 150 Teeth diagnosed with irreversible pulpitis or necrotic pulps included in a larger prospective trial,were selected for the study( REC: 08/H0804/79).The operators were allowed to choose between the two obturation techniques. Primary root canal treatments were carried out using ProTaper®Next nickel-titanium rotary instruments (Dentsply Sirona) in a crown-down approach to prepare each root canal to at least a X2 master apical rotary file. The canals were obturated using warm vertical condensation of gutta-percha and AH plus (Dentsply Sirona) or BioRootTM RCS (Septodont) and a single cone technique. The teeth were then restored with permanent glass ionomer cores (Fuji IX® glass ionomer cement) or composite resin (Herculite ultra®; Kerr corporation, Orange, CA, USA). CBCT and PA radiographs were made at baseline and at 12 months recall.
The increase or decrease in the size of preoperative periapical radiolucencies and development of new radiolucencies were assessed by a consensus panel consisting of two pre-calibrated examiners.
Statistical analysis was undertaken using fisher Exact Test
Results: At 1 year recall 104 teeth were assessed (51 Ah plus, 53 BioRootTM RCS). The success rate using loose criteria for the CBCT images and PA Radiographs was respectively 80% and 89% in the Ahplus/Warm vertical condensation group, 84% and 90% in the BioRootTM RCS single cone group. Difference between two groups was not statistically significant and no adverse event were observed.
Conclusions: Within the limitations of this non-randomized trial, BioRootTM RCSin combination with single cone technique resulted in a proportion of successful outcomes similar to that of warm vertical condensation and AH plus.
