COVID-19 is an emerging, rapidly evolving situation. 2018; 21:10-. Composite. Material and methods: There was a statistically significant difference between TheraCal LC and both BD and TotalFill in terms of pulpal inflammation during the 3 capping periods, while BD and TotalFill showed comparable results, with no statistically significant difference between their results in the 3 capping periods. Significant differences in the percentage of cytotoxicity between diluted and undiluted extracts between all tested materials after 24 h and 7 day were noticed (p < 0.05). Significance Treatment of dental caries implies the use of materials having regenerative and anti-bacterial properties, and controlling inflammation is critical for successful endodontic regeneration.

Immunohistochemistry studies revealed that nanostructured materials induced proliferation of hepatocytes, but that the immunological response to the materials was not strong enough to induce proliferation of immunoreactive cells in liver in the observed time period. J Dent. Statistical analysis was performed using parametric (ANOVA and t test) and non‐parametric tests (Kruskal‐Wallis and Mann‐Whitney U test) depending on data distribution. Direct pulp capping with mineral trioxide aggregate or calcium-hydroxide followed by the light-cured resin-modified glass ionomer liner and a bonded bulk-fill composite restoration induced temperature changes below the potentially adverse threshold of 42.5°C. 1981 Dec;9(4):271-98. doi: 10.1016/0300-5712(81)90001-4. Camilleri J. Each disc was divided in five parts; one of those served as baseline control. 172026 and Grant no. Twenty four Albino Wistar rats aged two months were used as an in vivo animal model for subcutaneous implantation of the investigated materials, placed in polyethylene tubes. This in vitro study demonstrated that Biodentine and Compomer were more biocompatible than the other root-end filling materials. In the first experimental group teeth were obturated using different sealers: Gutta Flow (Roeko), AH Plus (DeTrey), Acroseal (Septodont) and mono gutta-percha cone (10 canals each). investigations while 21 references comprised reports, reviews and books trioxide aggregate or calcium-enriched mixture cement: An ex vivo study. Dental materials: 1979 literature review. The pH values of ALBO-MPCA1 and ALBO-MPCA2 were high alkaline, while in case of MTA⁺ they were lower and continuously declined (p < 0.05). The teeth were examined 0.19 to 7.4 (mean 2.3 ± 2.04) years after treatment. Vitrebond eluate caused necrotic cell death. Teeth were divided into three groups according to the materials used for pulp capping. Pain was recorded using the visual analog scale every 24 hours for 7 days after intervention. data collection is necessary, CSs are promising materials that represent a Eur J Paediatr Dent. 12.

Introduction However, their biological properties are still mutually comparable. After immersion in saline, MTA+ was significantly less soluble than ProRoot MTA (P<0.001); when immersed in HBSS, no significant difference was found (P = 1.00). Asgary S, Shahabi S, Jafarzadeh T, Amini S. Von Arx T. Apical surgery: A review of current techniques and outcome. Attachment of osteoblasts on the surface of an experimental, calcium silicate cement. Specimens were prepared to evaluate setting time (n=6 for each group, specimen dimensions 10x8x5mm), solubility (n=6 for each group, specimen dimension 20 mm in diameter and 1.5 mm thick) after 1 and 28 days, pH (n=10 for each group, specimen dimensions 10 mm in diameter and 1 mm thick) after 1, 7, 14, 21 and 28 days and surface roughness (n=10 for each group, specimen dimensions 4 mm in diameter and 3 mm high) after 28 days when cements were cured at 95% humidity or immersed in saline or HBSS at 37°C. Third-generation biomedical materials. pH values of materials’ suspensions were conducted by pH-meter. Stereological measurements were achieved using Cavalieri's principle, with grid P2 and unbiased analysis. Moreover, these materials can be used for dentin regeneration or as advanced drug delivery systems. Should not produce allergic responses. Material and Methods Sixty-six freshly extracted single rooted (single canal) teeth were divided into the two experimental (30 teeth) and one control group (6). Microscopy.

Conclusions Tandteknikern. hPDL fibroblasts were plated at a density of 5 × 10³/well, and were incubated for 24 hours with 1:1, 1:2, 1:4, and 1:8 dilutions of eluates. Results The kappa value of interrater agreement was 0.773.No significant difference in pain incidence was found between the 2 groups (P > .05) although a significant pain reduction was found 6 hours after the procedure in both the groups. Setting time was significantly shorter when cements were cured at 95% humidity compared to those in saline (P<0.001) and HBSS (P<0.001). emical, structural, and particularly geometric design at various levels of ordering (from nanometric to macroscopic level). TotalFill a newly developed pulp-capping material, offers results comparable to BD in addition to its advantageous handling properties. Several haematological and biochemical parameters of blood of experimental animals were also analyzed, as well as local tissue reactions around the implants. A total of 12 in vitro studies were included in this review. Magnifications: (a) ×500, (b) ×2000, (c) ×5000. Schembri M, Peplow G, Camilleri J. Analises of heavy metals in mineral trioxide aggregate and Portland cement. 4. After exposure, hemostasis was obtained and the pulp-capping agents BD, TheraCal LC and TotalFill were applied.  |  Saad AY. III 45005]. Conclusion All rights reserved. All samples were composed of round and needle-like particles equally distributed with Ca/Si ratio ~2.7 at%, with the presence of hydrated calcium silicate phases. Ten discs from each material were fabricated in sterile Teflon molds and 24-hour eluates were obtained from each root-end filling material in cell culture media after 1- or 3-day setting. Cements' porosity was determined using mercury intrusion porosimetry and micro-computed tomographic (μCT) imaging. The level of significance was set at P = 0.05. [Project of the Serbian Ministry of Education, Science and Technological Results Methods: The aim of the study was to evaluate the reparative capacity of Biodentine™ (BD), TheraCal® LC and TotalFill® as DPC materials and to assess dentin bridge formation. investigating mineral trioxide aggregate versus calcium hydroxide. The aim of this in vitro study was to evaluate the biocompatibility of newly proposed root-end filling materials, Biodentine, Micro-Mega mineral trioxide aggregate (MM-MTA), polymethylmethacrylate (PMMA) bone cement, and Smart Dentin Replacement (SDR), in comparison with contemporary root-end filling materials, intermediate restorative material (IRM), Dyract compomer, ProRoot MTA (PMTA), and Vitrebond, using human periodontal ligament (hPDL) fibroblasts.
