About this trial

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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Individuals aged 30 to 45 years.

Presence of at least one tooth with a non-carious cervical lesion (Class V) with a lesion depth of ≥1 mm, requiring restorative treatment.

The NCCL must show some symptoms/signs of pre-op sensitivity on applying stimulus (i.e Air burst / ethyl chloride spray) and will be recorded.

The involved teeth must be vital and show no signs or symptoms of irreversible pulpitis or necrosis.

Disqualifiers

Presence of carious lesions or restored teeth with existing secondary caries

Any tooth with pulpal involvement, previous root canal therapy, or periapical pathology.

Teeth with chronic periodontal disease( BPE score 3 and above.).

Individuals regularly using Desensitizing toothpastes, NSAIDs, antidepressants, or any other pain-modulating drugs that may alter sensitivity reporting.

Trial design

Design model

Parallel

Treatments tested in this trial

  • Dipotassium Oxalate Gel

    Combination product

    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.

Treatment groups

64 Participants
are divided into 2 treatment groups
Group A: Dipotassium oxalate pretreatment before composite restorationExperimental treatment 1 intervention
Group B: No Dipotassium Oxalate Pre-treatment, Standard composite filling onlyNo intervention 0 interventions
