Efficacy of Nanoparticle-incorporated Bonding Agent on Post-restorative Sensitivity

Clinical Efficacy of a Novel Titania Nanoparticle-Reinforced Bonding Agent in Reducing Post-Restorative Sensitivity: A Randomized Clinical Trial

Type of study: Randomized Clinical trial To compare post-restorative sensitivity between titania nanoparticle reinforced bonding agent and bonding agent without nanoparticles in posterior composite restorations. Participants aged 18 years and above with Class-I and Class-II Carious lesions are allocated in two groups. Group A will undergo composite restoration with Nanoparticles incorporated in bonding agent. Group B will undergo restoration without nanoparticles in bonding agent.

In this study Novel titania nanoparticle reinforced bonding agent will be evaluated for post-restorative sensitivity in composite restorations. Participants following the Inclusion criteria will be allocated in this study by Consecutive non-random sampling technique. Participants will be divided into two groups A and B. After rubber dam isolation, carious lesion will be excavated. In group A, titania nanoparticle reinforced bonding agent will be used for restorative treatment while in group B, Bonding agent without nanoparticles will be used. Post-restorative sensitivity record will be taken at 24 hours, after one week and after one month. Sensitivity will be assessed using Visual analog scale (VAS) mean score.

In this study, participants will be allocated in two groups by Consecutive non-random sampling technique.

This is a triple-blinded study in which the participant, care provider and outcome assessor will be masked.

Group A will receive composite resin restoration with Titania nanoparticle incorporated bonding agent

Group B will receive composite resin restoration without Titania nanoparticle incorporated bonding agent

Each group will receive Composite resin restoration for Class-I and Class-II carious lesion. In group A, titania nanoparticle reinforced bonding agent will be used

Evaluation of bonding agent with titania nanoparticles and without nanoparticles on post-restorative sensitivity using Visual analog scale with scoring from 0 to 10. Score 10 means worst outcomes
