Comparison of calcium hydroxide paste with kenacomb (corticosteroid-antibiotic paste) for postoperative endodontic pain in acute apical periodontitis: a randomized controlled trial.
Pak Armed Forces Med J Jan ;64(1):39-45.

Objective: To compare the postoperative endodontic pain following root canal treatment in teeth with acute apical periodontitis, using calcium hydroxide paste and kenacomb as intracanal medicaments. Study Design: Randomized controlled trial. Place and Duration of Study: Department of Operative Dentistry Armed Forces Institute of Dentistry (AFID) Rawalpindi from January 2010 to December 2010. Patients and Methods: Seventy patients with acute apical periodontitis from necrotic pulps were divided into two groups. Calcium hydroxide was given to patients in group A and kenacomb to group B patients as intra-canal medicament in paste form. Endodontic therapy followed a strict clinical regimen that included examination, administration of local anesthetic, establishment of proper access, thorough irrigation and debridement, working length determination, root canal dressing with intra-canal medicament and sealing the access cavity with cavit in between appointments. Post-operative endodontic pain was recorded on visual analogue scale after 04 hours, 24 hours, 48 hours and 72 hours. Data was analyzed by SPSS version 12. Results: There was no statistically significant difference between calcium hydroxide and kenacomb paste in reducing post-operative endodontic pain in patients with acute apical periodontitis. Conclusions: Calcium hydroxide and kenacomb paste has similar effect on post-operative endodontic pain in patients with acute apical periodontitis from necrotic pulps.
