Histological Study of the Effects of Ibuprofen on Acute Apical Inflammation Following Root Canal Therapy in Cats
Abstract
Postoperative pain following Root Canal Therapy (RCT) is the common problem for patients,"ndentist and dental staff. Regardless of cause it appears that postoperative pain and discomfort is related to"nperiapical inflammation. The purpose of this study was to investigate histologically the effect of"nIbuprofen on acute apical inflammation following RCT. on cat. Fifty-six cuspids teeth of 14 cats were"ndivided into three groups, 6 cats for experimental group, 6 cats for positive control group and 2 cats for"nnegative control group. In first group, to anesthesize the animals each cat received 10 mg/kg Ibuprofen"n36 hours before RCT and repeated every 24 hours. In second group RCT was performed in 24 cat teeth"nwithout any prescription. In negative control groups 2 cats, no RCT were done."nFollowing vital perfusion, in interval of 6, 12, 24 hours, samples were post fixed in 10% formalin and"nfive micron sections were prepared, and stained with H&E and studied under the Mann Whitney"nparameter test. Infilteration of inflamatory cells in 6 hours interval in experimental group was"nsignificantly less than two control groups. In 12 hours samples, however, inflammation in experimental"ngroup reduced, but it was not significant. In 24 hours samples there was no significant difference"nbetween experimental groups and controls. The result of this in-vivo study shows prescription of"nIbuprofen before root canal therapy can reduce inflammatory reaction.
