Comparative evaluation of remineralisation potential using BioHAP, CPP-ACP and Enamelon on root dentin: An in vitrostudy.

Root caries and cervical dentin hypersensitivity affect older adults with gingival recession, requiring effective remineralisation strategies for root dentin preservation. Therefore, it is of interest to compare remineralisation potential of BioHAP, CPP-ACP and Enamelon on artificially demineralised root dentin from 60 extracted premolars using a 28-day pH cycling protocol. All agents significantly increased microhardness versus control (p<0.001), with BioHAP achieving superior recovery at 68.42±7.83% compared to other groups. SEM analysis confirmed BioHAP's enhanced mineral deposition and dentinal tubular occlusion, demonstrating superior structural repair capabilities. These findings advance restorative dentistry by establishing BioHAP as the optimal commercial agent for root dentin remineralisation and hypersensitivity management.
