This triple-blind, randomized clinical trial was conducted at the department of Operative dentistry. A total of 60 participants were recruited and were randomly distributed into two groups A and B. After informed consent, restorative treatment was performed. In group A, adhesive with nanoparticles was used for composite restoration while in group B, adhesive without nanoparticles was utilized. Post-operative sensitivity was recorded using VAS score.

Triple-blind, randomized trial, parallel group with an allocation ratio 1:1. A total of 60 participants were recruited from the outpatient department and were randomly distributed into two groups (n=30). After informed consent, restorative treatment was accomplished using an etch and rinse adhesive strategy. In group A , titanium dioxide nano-fortified adhesive was used while in group B, adhesive without nanoparticles was utilized for composite restoration. Post-operative sensitivity was evaluated at follow-up period: one day, one week, two weeks and one month. Visual Analogue scale score was used to record the sensitivity status at follow-up intervals.
