Dipotassium Oxalate for Postoperative Sensitivity in NCCLs
Sponsor: Postgraduate Medical Institute, Lahore
Summary
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.

Interventions
Dipotassium Oxalate Gel
Application of a 3% dipotassium oxalate gel to exposed dentin in non-carious cervical lesions prior to adhesive placement. The material is applied for 90 seconds and gently air-dried without rinsing, following manufacturer instructions. This pretreatment aims to occlude dentinal tubules through calcium oxalate crystal formation before restoration with a standard etch-and-rinse adhesive system and nanohybrid composite resin.
