Clinical Trial Summary

The aim of this study is to assess the clinical effect of aPDT on deep caries in permanent teeth. Half of the deep caries will receive aPDT disinfect in restorative treatment procedure, while the other half will receive sodium 0.9% saline in restorative treatment procedure.


Clinical Trial Description

The aim of the proposed study is to assess the clinical effect of antimicrobial photodynamic therapy (aPDT) using LED on dentin with deep caries in permanent teeth. Permanent teeth with deep carious lesions on the occlusal surface indicated for restorative treatment will be randomly allocated to two groups: Group 1 -Control after incomplete caries removal, washed with sodium 0.9% saline; Group 2 - PDT + CH after incomplete caries removal, disinfect the residual dentin with PDT(LED + O-Toluidine Blue). Dentin samples will be collected before and after disinfect for microbiological analysis. Then the teeth will be capped with CH and restored using resin with clinical and radiographic follow up at 6, 12 and 24 months. ;
