Introduction: The purpose of the current study was to estimate the biocompatibility of endodontic sealers with different bases on L929 mouse fibroblasts permanent cell line using Multiscan EX Spectrophotometer.
Materials And Methods: Endodontics sealers used in this study were GuttaFlow (Roeko) silicone based sealer, AH plus (De Tray-DENTSPLY) epoxy resin based, Apexit (Vivadent) calcium hydroxide based and Endorez (Ultradent) methacrylate based sealer. Sealer were tested trough time, freshly mixed 24 h, 48h and 7 days after setting. Biocompatibility was determinate on permanent cell lines L929 mouse fibroblasts trough cytotoxicity using MTT assay. Level of absorption was measured with multi scan EX spectrophotometer on length 420-600 nm.
Results: Sealer based on calcium hydroxide Apexit Plus, GuttaFlow silicone based sealer and AH plus epoxy resin based sealer, have shown a low cytotoxicity through the all periods of time on culture of L292 mouse fibroblasts. Methacrylate based sealer, Endorez showed moderate cytotoxicity when freshly mixed and after 7 days. After 24 hours the visibility of the cells was 74,0% and after 48 hours 65,1%. which is slightly cytotoxic.
Conclusions: According to results of this study there is a statistically significant difference among the groups p<0,05 for all the tested sealers. Apexit Plus, GuttaFlow and AH plus can be considered as biocompatibile. EndoREZ sealer which is based on methacrylate, after 7 days shows 50,1% of visible live cells which is considered as moderate cytotoxicity.

With the advent of bioceramic sealers, sealers have become a more important filling material for endodontic treatment. When a solid sealer, rather than an elastic gutta-percha, occupies a significant portion of the root canal, it is unclear whether the tooth structure will be strengthened to withstand stress or whether the increased stiffness will transmit the load directly to the entire root, potentially causing root fracture. This study compared the fracture resistance and fracture patterns of roots filled with various root canal sealers, including bioceramic sealers, and each corresponding filling technique.

This micro-computed tomography (micro-CT) analysis in vitro study was designed to compare void volume in root canal fillings performed using the single-cone (SC) technique and the continuous wave condensation (CWC) technique with bioceramic (BC) sealer. Forty human-extracted, single-rooted mandibular premolars were cleaned, shaped, and divided into two groups (n = 20) based on the obturation technique. In the first group, obturation was performed using the CWC technique with TotalFill HiFlow BC sealer.

This study evaluated the cytotoxicity and biocompatibility of a new strontium silicate-based root canal sealer (C-Root SP), in comparison with those of iRoot SP and AH plus. The sealer extract was diluted to the concentrations of 100%, 75%, 50%, and 25%. L929 cells were cultured for 24 h, and the absorbance value was determined.

Adhesion within endodontic obturation material and root canal walls improves the efficacy of the endodontic treatment by establishing a barrier that inhibits reinfection and entombs residual bacteria. This study evaluates the push-out bond strength (POBS) of calcium silicate sealers compared to an epoxy-resin-based sealer. A total of 36 extracted mono-radicular teeth were prepared with Pro Taper Ultimate and irrigated with 5.

Background: This study aimed to assess and compare the performance of root canal treatment obturated either with calcium silicate-based or epoxy resin-based root canal sealers on retreatment cases with periapical lesions.
Methods: Patients' radiographic data and clinical records were obtained retrospectively from the computerized patient record system. A total of 44 teeth, 28 teeth treated with calcium silicate-based sealer and 16 teeth treated with epoxy resin-based sealer, were included in the study.
