Summary

The study involved 54 adult patients between the ages of 18 and 50 years who had a posterior permanent tooth with a deep occlusal (Class I) carious lesion that extended to the inner third of the dentin (D3) and divided them into two equal groups randomly (N=27) according to the caries removal technique: group 1 (SE), and group 2 (SW). Then each main group was equally subdivided into three equal subgroups (n=9) according to the applied dentin dressing material as follows: Subgroup 1: Nano-silver compound (NSC), Subgroup 2: Chitosan-loaded nano hydroxy apatite (CS/N-HAp), Subgroup 3: Bioactive glass ionomer (N-BAG/GIC). At the first visit both groups received the same treatment of incomplete caries excavation, application of dentin dressing materials and sealing temporarily for 3-months with a glass ionomer cement (GIC). At the second visit the GIC reduced pulpally in (SE) group leaving 2 mm as base and completely removal the remaining carious lesion in (SW) group then re-application of same dentin dressing material on each tooth and GIC as a base. Finally, all cavities were restored with selective enamel etching technique, after which self-etch adhesive and Nano-filled composite resin are applied according to manufacturer instructions. The clinical and digital radiographic evaluations of the success and failure rates were performed at: baseline (7 days), 3, 12, and 18-months.
