The efficacy of transdermal and oral diclofenac for post-endodontic pain control: A randomised controlled trial.

OBJECTIVE

The aim of the present study was to compare the effect of transdermal diclofenac patch against oral diclofenac for post-endodontic pain control.

MATERIALS AND

METHODS

Thirty-two patients with symptomatic irreversible pulpitis in single-rooted premolar teeth of either arch were treated endodontically in a single visit by a single endodontist. Oral diclofenac (50 mg twice daily) for group I and transdermal diclofenac patch (100 mg once daily) for group II were administered as post-endodontic analgesics for two days. Visual analogue scale (VAS) chart was used to record pain intensity scores preoperatively and at intervals of 4, 8, 12 and 24 h postoperatively for 2 days. Paracetamol 650 mg tablets were provided as rescue medication.

RESULTS

There was a significant decrease in the postoperative pain intensity scores for both groups. The postoperative scores gradually decreased from day 1 to day 2 in both groups. Twelve out of sixteen patients who had received diclofenac tablets complained of gastric discomfort.

CONCLUSION

Transdermal diclofenac patch was as effective as an oral diclofenac tablet and can be used as an alternative and effective analgesic for post-endodontic pain management, especially in patients with gastric discomfort.
