Finally, biological and medical investigations will be performed to estimate potential medical applicability of these systems “in vitro”, by using particular cell lines, and “in vivo by using appropriate animal models. Biodentine: Periodontal perspective. Results Material and methods: Exposed pulps were capped using standardized protocols. Significantly lower pain scores were reported in the MTA group (6.3 ± 9.5) compared with the CH group (18.5 ± 20.8) after 18 hours. Although these materials induced several changes in the liver structure, they were not clinically relevant and represent a normal and reversible response of the liver to the presence of biocompatible materials in the body. filling material: A systematic review. Schröder U. Restor Dent Endod. Quality assessment of the selected studies was performed according to the PRISMA guidelines, 2009. Maintaining pulp vitality is a major objective in restorative dentistry. Conclusions These results support the idea that the success of IPC is independent from the capping material. Fifty-six patients were analyzed at the 12-month follow-up, 29 treated with CH and 27 with ProRoot MTA (Dentsply Tulsa Dental, Tulsa, OK). Should not be mutagenic. Materials' wettability was calculated concerning the contact angles of the cements measured using a glycerol drop. The level of significance was set at P = 0.05. Dent Pract Dent Rec. J Dent.

Methods. Objectives: To evaluate the radiopacity of Biodentine (BD) and BD associated with 15% calcium tungstate (BDCaWO4) or zirconium oxide (BDZrO2), by using conventional and digital radiography systems, and their physicochemical and biological properties. Biodentine had the lowest value of microporosity (1.2% and 0.8% before and after SBF, respectively) and the lowest value of microgap to the root canal wall ([10 ± 30] × 10-3 mm3). The primary outcome was success rate at the 12-month follow-up, and the secondary outcome was postoperative pain after 7 days. 5.

It may be concluded that good sealing ability of biodentine along with its favorable biological properties show that materials can be used competently in clinical practice as a retrograde filling material. Should not contain toxic diffusible substances. Maheaswari R, Jeeva RM. Increase in L929 cells proliferation was noticed in case of undiluted eluates of ALBO-MPCA1 and ALBO-MPCA2 after 7 day (p < 0.05). Setting time of MTA+ was significantly shorter than that of ProRoot MTA (P<0.001), which had a significantly higher pH than MTA+ (P<0.05) for all periods and immersion liquids. data collection is necessary, CSs are promising materials that represent a Cell viability was evaluated by XTT assay. MTA proved better than CH in terms of both success rate and pain intensity. 109 scientific articles were Clinical findings in applications of calcium silicate ceme, and iRoot-BP cements application for pulpotomy treatment. Best SM, Porter AE, Thian ES, Huang J. Bioceramics: past, present and future.

This randomized clinical trial aimed to compare the success rate and postoperative pain of direct pulp capping (DPC) using calcium hydroxide (CH) and mineral trioxide aggregate (MTA) in teeth with carious pulp exposures and reversible pulpitis. fibroblasts. Clinical relevance All canals were instrumented using hand and rotary files in step-back technique and copious irrigation of 1%NaOCl. Mechanical properties and parameters that are measures of the elastic strain or plastic strain behavior of dental materials include elastic modulus (also called Young’s modulus or modulus of elasticity), dynamic Young’s modulus (determined by the measurement of ultrasonic wave velocity), shear modulus, flexibility, resilience, and Poisson’s ratio. All four restorative materials induced mineral gains regardless of the protocol for caries lesion, without significant differences between materials. Other materials apart from titanium, such as cobalt-chromium and stainless steel, were occasionally used for dental implants during the practice’s infancy. This article is protected by copyright. Conclusions Several materials have been used for this procedure. The success rate was 69% for CH and 93% for ProRoot MTA (P < .05).
