Objective: The Purpose Of This Clinical Trial Was To Assess The Effect Of Glass Ionomer Restoration With And Without Application Of Nano Silver Fluoride (NSF) Solution On The Remaining Carious Dentin Remineralization And Tertiary Dentin Formation After Partial Caries Removal In Occlusal Carious Molars.
Methods: This Was A Split Mouth Study That Included Twenty-two Patients Having Two Contralateral Deep Occlusal Carious Molars. A Total Of 44 Cavities Were Prepared With Partial Caries Excavation Technique. For Each Patient, The Cavity At One Side Was Treated With 0.2 Ml Of NSF Solution Prior To Glass Ionomer Restoration With Glass Hybrid System; This Comprised The Study Group. For The Other Side, Glass Hybrid Was Directly Applied Into The Cavity; This Comprised The Control Group. Standardized Digital Periapical Radiographs Were Performed At Baseline And After 6 Months. The Carious Dentin Density And The Remaining Dentin Thickness Were Assessed.
Results: 16 Out Of The 22 Included Patients Completed The Study. Statistically Significant Increase In Both The Dentin Density And The Remaining Dentin Thickness Were Found In Both Groups After 6 Months. The Percentage Change In The Density After 6 Months Was Significantly Higher For The Study Group. However, No Statistically Significant Difference Was Found Between Both Groups In The Thickness Of The Tertiary Dentin Formed. One Case Of Clinical Failure In Each Group Was Observed.
Conclusions: Partial Caries Removal For Deep Carious Lesions And Glass Hybrid Restoration With And Without Prior Application Of NSF Proved Remineralization Of The Remaining Carious Dentin, And Tertiary Dentin Formation. Carious Dentin Remineralization Was Better Using NSF Which Indicates Its Promising Role In Caries Arrest.
