Abstract：AIM:This study investigates the sealing effect of bioactive glass(BAG)when added to dentin adhesive,with a focus on its ability to occlude dentin tubules.METHODS:Teeth were Isolated and prepared as dentin trays,then acid-etched with 6%citric acid to simulate dentine hypersensitivity.Various concentrations of BAG(0%,5%,10%,20%,and 30%)were incorporated into the dentin bonding agent.The remineralisation process was carried out over 14 days.Dentin surface remineralisation,tubule sealing and adhesive penetration were evaluated using dentin permeability tests and abrasive challenges.RESULTS:After 14 days,all combination groups(dentine adhesive with BAG)showed remineralization of demineralized dentin,with a significant increase in dentin hardness.Among them,the 20%BAG group demonstrated the most substantial improvement in dentin hardness.Compared to the pure dentin adhesive,the combination groups exhibited superior wear resistance and a higher rate of tubule sealing.Dentin permeability was significantly reduced in all treatment groups compared with the control group.After storage in artificial saliva for 14 days,the combination groups showed a significant reduction in dentin permeability compared tothe pure dentin adhesive group.CONCLUSION:The combination of dentin adhesives and BAG demonstrated excellent remineralizing and occlusion of dentin tubules,offering a promising strategy for the treatment of dentin hypersensitivity.
