Abstract

Aim: To evaluate the tissue reaction of a tricalcium silicate‐based repair material associated with 30% calcium tungstate (TCS + CaWO4) in comparison to Bio‐C Repair (Bio‐C; Angelus) and to MTA Repair HP (MTA HP; Angelus). Methodology: Polyethylene tubes filled with one of the materials or left empty (control group, CG) were implanted into the subcutaneous tissues of rats for 7, 15, 30 and 60 days (n = 32/group). The capsule thickness, number of inflammatory cells, collagen content, interleukin‐6 (IL‐6), osteocalcin (OCN), von Kossa reaction and analysis under polarized light were evaluated. The data were subjected to generalized linear models for repeated measures, except the OCN. OCN data were submitted to Kruskal–Wallis and Dunn's post hoc test and Friedman followed by Nemenyi's test at significance level of 5%. Results: At all time points, significant differences in the number of inflammatory cells were not observed between TCS + CaWO4 and Bio‐C, whereas, at 15, 30 and 60 days, no significant difference was detected between TCS + CaWO4 and MTA HP. At all periods, significant differences were not detected in the number of fibroblasts in TCS + CaWO4 versus MTA HP, and, at 60 days, no significant difference was demonstrated between these groups and CG. Significant differences in the immunoexpression of IL‐6 were not detected amongst bioceramic materials at all periods. From 7 to 60 days, significant reduction in the number of inflammatory cells, number of IL‐6‐immunopositive cells and in the capsule thickness was accompanied by significant increase in the collagen in all groups. OCN‐immunolabelled cells, von Kossa‐positive structures and amorphous calcite deposits were observed around all materials, whereas, in the CG, these structures were not seen. Conclusions: These findings indicate that the experimental material (TCS + CaWO4) is biocompatible and has a bioactive potential, similar to the MTA HP and Bio‐C Repair, and suggest its use as a root repair material.

Abstract

This study evaluated the physicochemical and biological properties of novel reparative materials composed of pure tricalcium silicate (Ca3SiO5), Ca3SiO5 doped with fluoride ions (Ca3SiO5‐F) and their association with ZrO2 (Ca3SiO5 + ZrO2, Ca3SiO5‐F + ZrO2), in comparison with Biodentine (BIO). Setting time radiopacity, pH, solubility, and dimensional change were evaluated based on ISO 6876 Standard. Volumetric change and flow/filling were assessed by microcomputed tomography (micro‐CT). Biological properties were evaluated by the MTT assay 3‐(4,5‐dimethylthiazol‐2‐yl)‐2,5‐diphenyltetrazolium bromide), Neutral Red (NR), cell migration, alkaline phosphatase activity (ALP), and Alizarin Red Staining (ARS) assays. Statistical analysis was performed by ANOVA, Tukey, or Bonferroni tests (α =.05). Ca3SiO5‐F + ZrO2 had higher radiopacity, shorter setting time, and lower solubility and volumetric loss than BIO (p <.05). Ca3SiO5‐F + ZrO2 had flow and filling capacity similar to BIO (p >.05). All the cements evaluated had an alkaline pH. Ca3SiO5‐F + ZrO2 demonstrated cell viability similar to negative control (p >.05), increase in ALP activity in 7 days, mineralized nodule production in 21 days and repair capacity according to cell migration. In conclusion, Ca3SiO5‐F + ZrO2 had adequate setting time, radiopacity, solubility, and dimensional change. This material presented low volumetric change besides flow and filling capacity in micro‐CT assessment. In addition, Ca3SiO5‐F + ZrO2 was biocompatible and bioactive, suggesting its use as reparative material. [ABSTRACT FROM AUTHOR]
