Abstract
This study was carried out to observe immediate inflammatory response of Human Dental Pulp capped with Biodentin and Mineral Trioxide Aggregate (MTA). This prospective clinical study was carried out in the Department of Conservative Dentistry and Endodontics together with the Department of Orthodontia, Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh from 2016 to 2018. A total number of eighty (80) permanent premolars teeth planned to be extracted for orthodontic alignment of occlusion were used as study sample. Those teeth were divided into two groups; Group A and Group B, having 40 teeth in each (n=40). An occlusal exposure of approximately 1.5mm in diameter was made. Then in -group A, exposed pulp were capped with 2-mm-thick layer of sterile Biodentin (Septodont) and in-group B with ProRoot White MTA (Dentsply). After pulp capping with the experimental material in respective group, cavities in all teeth were restored with glass ionomer cement. After 24 hours the teeth were extracted, fixed in 10% buffered formalin solution, then decalcified by 10.0% nitric acid and embedded in paraffin. Now 2 to 3-micron-thick serial sections were made in the linguo-buccal plane and finally stained with hematoxylin-eosin. Now pulpal inflammation in respect of type, intensity and extension, were determined by using a predetermined evaluation criterion under an optical microscope at 40× magnifications. Statistical differences among the experimental groups were analyzed by Descriptive analysis (Cross Tabulation) (p<0.05). Histologically both the tested materials produced immediate pulpal tissue reaction. 'Biodentin' found to be most immediate pulpal tissue reactive (reactive in 100% cases), Whereas, MTA produced immediate tissue reaction only in 50.0% cases. Immediate pulpal inflammatory reaction in response to tested material found to be statistically significant different between 'Biodentin' and 'MTA' (p=0.001). According to present study Biodentin is found to be more immediate pulpal tissue reactive than MTA when used as a pulp capping material.
