Dipotassium Oxalate for Postoperative Sensitivity in NCCLs

Postoperative sensitivity is a common complication following Class V composite restorations, particularly in non-carious cervical lesions (NCCLs). This randomized controlled trial aims to evaluate the effectiveness of dipotassium oxalate as a pre-treatment agent in reducing postoperative sensitivity. A total of 64 participants will be randomly assigned into two groups: an intervention group receiving dipotassium oxalate prior to adhesive application, and a control group receiving standard adhesive protocol without pretreatment. Sensitivity will be assessed using a Visual Analog Scale (VAS) in response to cold and air stimuli at baseline, 24 hours, 7 days, and 30 days. The study aims to determine whether dipotassium oxalate significantly reduces postoperative sensitivity and can be incorporated into routine restorative dental practice.
