Addition of phosphates and chlorhexidine to resin-modified MTA materials
ABSTRACT:
The addition of phosphates and chlorhexidine to resinmodified MTA was performed to synthesize a novel type of endodontic sealer for root-end filling procedure. This study showed that MTA resin-modified root-end fillings without chlorhexidine digluconate are promising materials for endodontic treatments, since these experimental sealers presented effective physico-chemical and biological properties.

The effects of sodium hypochlorite and ethylenediaminetetraacetic acid on the microhardness of Mineral Trioxide Aggregate and Total Fill Bioceramic Putty
ABSTRACT:
MTAA had a higher baseline microhardness than BCP. NaOCl reduced the microhardness of MTAA but increased that of BCP. EDTA reduced the microhardness for both materials at 24 h. At 8 days, EDTA reduced the microhardness of MTAA, while BCP exhibited an increase in microhardness. Enabling these materials to set for a week prior to exposure to irrigants improves their microhardness.

Comparative Cytocompatibility and Mineralization Potential of Bio-C Sealer and Total Fill BC Sealer
ABSTRACT:
Based on the results from this study, Bio-C Sealer and TotalFill BC Sealer demonstrated better cytocompatibility in terms of cell viability, migration, cell morphology, cell attachment, and mineralization capacity than AH Plus.

Evaluation of Physicochemical Properties of a New Calcium Silicate–based Sealer, Bio-C Sealer
ABSTRACT:
Bio-C Sealer is a new calcium silicate–based root canal sealer that has an adequate setting time, flow, and radiopacity. Although this material had high solubility, the micro-CT assessment indicated low volumetric change.

Cytotoxicity, Biocompatibility and Biomineralization of a New Ready for- Use Bioceramic Repair Material
ABSTRACT:
New mineral trioxide aggregate (MTA) formulations are constantly introduced in the market, usually in a powder-and-liquid form. Bioceramic (Bio-C) Repair is a ready-for-use material suggested as substitute for MTA, but its properties need to be studied. This study evaluated the cytotoxicity, biocompatibility and biomineralization of Bio-C Repair compared to MTA Repair High-Plasticity (MTA-HP) and white MTA-Angelus (MTA-Ang). L929 fibroblasts were exposed to material-extracted (undiluted, ½ and ¼ dilutions; 6, 24 and 48h). Polyethylene tubes with material or empty (control) were implanted in the subcutaneous tissue of rats. After 7 and 30 days (n=8), the specimens were removed for analysis (hematoxylin-eosin, von Kossa and polarized light). Cytotoxicity data were statistically analyzed by two-way ANOVA, and biocompatibility data by Kruskal-Wallis and Dunn tests (p<0.05). The cells exposed to the materials had greater viability at most of the periods compared with control (p<0.05). The undiluted and ½ dilutions of MTA-HP extract showed higher cytocompatibility than Bio-C Repair at 6 h and with the ¼ dilution at 24 h (p<0.05); the white MTA-Ang showed higher cytocompatibility than Bio-C Repair at most of periods (p<0.05). The undiluted white MTA-Ang extract had higher cytocompatibility at 6 and 24h than MTA-HP, and with ½ dilution at 24h (p0.05). At 7 and 30 days, the groups had moderate and mild inflammation, respectively (p>0.05). All materials showed positive structures for von Kossa and polarized light. In conclusion, Bio-C Repair had similar cytocompatibility to MTA-based materials is biocompatible and induces biomineralization.

The use of a new bioceramic material in endodontic microsurgery
ABSTRACT:
Synergism of clinical microscopy and ultrasonic devices allows the execution of extremely precise treatments. Endodontic microsurgery, when performed within the modern concepts, is a remarkable therapeutic alternative, predictable and viable for the conservation of teeth with secondary or persistent apical periodontites. A new generation of premixed bioceramic products simplifies retrofilling procedures and might has elicited quicker and complete apical bone repair.

Comparação da eficácia de diferentes solventes orgânicos na dissolução do MTA-Fillapex
ABSTRACT:
Os solventes endosolv R (0,0065), citrol (0,0072) e eucaliptol (0,0077) resultaram em postos médios de solubilidade semelhantes entre si (p>0,05), todavia distintos (p0,05). Conclusões: Todos os solventes orgânicos testados apresentaram capacidade de dissolução do MTA Fillapex, sendo o xilol, clorofórmio e endosolv E os mais efetivos.

Impact of Mechanical Load of Three Post and Core Systems:CAD/CAM-fabricated Glassfiber, Prefabricated GlassfiberCustomized with Composite Resin, and Cast Metal Postsand Cores
ABSTRACT:
The fracture resistance of CAD/CAM-fabricated glassfiber posts and cores was comparable to that of cast posts and cores, and they were not associated with irreparable root fractures. Therefore, CAD/CAM-fabricated glassfiber posts and cores can be considered an effective method for restoring endodontically treated teeth.
