| dc.description.abstract | The aim of this study was to evaluate the mechanical properties of nano graphene calcium silico phosphate and nano zirconia calcium silico phosphate with commercially available Biodentine and analyze their chemistry using FTIR and SEM. Four groups were made, they are as follows: group 1: Biodentine (control group), group 2: nano graphene calcium silico phosphate (70% Biodentine+20% nano graphene+10% calcium phosphate), group 3: nano zirconia calcium silico phosphate (70% Biodentine+20% nano zirconia+10% calcium phosphate) and group 4: nano zirconia modified Biodentine (80% Biodentine+20% nano zirconia). Twenty samples were prepared, which consist of five samples of each group. All the powder contents of dental material were weighted on a digital weight machine and transferred to an airtight container for centrifugation and ultrasonication. Liquid was then added to powder content as per the manufacturer’s instruction and amalgamator was used to mix the powder and liquid. The mixture was then transferred to disk shaped acrylic molds and allowed to set at room temperature overnight followed by placing the samples in an incubator for 24 hours at 37⁰C and 100% humidity. After the initial set of all the groups, samples were demoulded and crushed with pestle and mortar into fine powder. Crushed samples were used for FTIR and SEM EDX analysis. The Vickers microhardness tester was used to measure the microhardness and universal Instron testing machine was used to check the compressive strength of samples. Data analysis was done using One-way ANOVA test and Games-Howell post-hoc test. Significance level was p<0.05. It was noted in the spectra of Biodentin and its modified groups 2,3, and 4 that the stretching vibration shifted from 3461.10 cm-1 to 470.84 cm- 1.SEM EDX analysis shows even distribution of splintered particles (1 - 10 μm) in conjunction with round (1 - 10 μm) and with particles smaller than 0.1 μm were observed. Group 3 (nano zirconia calcium silico phosphate) and group 4 (nano zirconia modified Biodentine) had higher microhardness than group 1 (Biodentine). Least microhardness value was recorded by group 2 (nano graphene calcium silico phosphate). Highest compressive strength was noticed by group 3 (nano zirconia calcium silico phosphate) followed by group 1 (Biodentine) and group 2 (nano graphene calcium silico phosphate) and the least value was recorded by group 4. Biodentine is an innovative biomimetic material applied in various fields of dentistry due to its suitable biological properties and higher physical and mechanical characteristics like natural dentine. Nano zirconia calcium silico phosphate group in this study showed favorable results. There was a noticeable increase in microhardness and compressive strength with the addition of nanozirconia and tricalcium phosphate to Biodentine. Further research is required to evaluate the toxicity, biocompatibility and osteoconductive nature of novel material. | |
