Participants will be divided into groups. In group A, Composite restoration done using oblique incremental technique. In group B, Bulk-fill technique was used. VAS scoring to evaluate the primary outcome at one day, one week and two weeks.

After the approval from ethical research committee, a written informed consent taken. Participants were briefed about the intervention with its associated merits and demerits. The restorative procedures were accomplished under rubber dam isolation using adequate local anesthesia. The principles of minimally intervention and adhesive dentistry were employed. Participants were allocated into two groups. In group A, restorative interventive was performed using Oblique incremental placement while in group B, Bulk-fill technique was used. Post-operative sensitivity was recorded at one day, one week and two week follow up using a Visual analogue scale.
