Comparative evaluation of microhardness of residual dentin in primary molars following caries removal with chemomechanical agent (BRIX 3000) and polymer burs (ss white)

Abstract

Aim: To evaluate and compare microhardness of residual dentin in primary molars following caries removal with chemomechanical agent (BRIX 3000) and polymer burs (SS white). Materials and Method: Extracted maxillary or mandibular primary molars with proximal carious lesion, were selected with active carious cavities extending in to 2/3rd of dentin. The selected teeth were preserved in phosphate buffer saline solution no longer than 30 days. The selected teeth were separated into two experimental groups: group A- chemomechanical method – Brix3000 and Group B- slow speed polymer bur. After caries excavation the microhardness test was carried out on treated dentin using a Knoop indenter. Results: The results suggest a significant difference between among the groups Brix 3000â showed superior results compared to group B (Polymer burs) i.e., The results showed that the microhardness of the remaining dentine after caries excavation with Brix 3000 was found to be greater than the microhardness of the remaining dentine after caries excavation with Polymer bur. Conclusion: In conclusion of the current study, it can be stated that Brix 3000 may be utilized as a successful agent in minimally invasive caries excavation since Polymer burs showed partial removal of carious dentine.
