COMPARISON OF POSTOPERATIVE PAIN WITH AND WITHOUT APICAL PATENCY TECHNIQUE IN ASYMPTOMATIC IRREVERSIBLE PULPITIS TEETH: A RANDOMIZAD CONTRAL TRIAL

Objective: To compare postoperative pain in asymptomatic irreversible pulpitis teeth with and without apical patency application during root canal treatment. Materials and Methods: A randomized contral trial was carried at Armed Forces Institute of Dentistry, Rawalpindi started July 2013 to Jan 2014. A total of 150 teeth (75 in each group) were randomly divided in two groups. In group A apical patency was applied with smallest file (8 or 10 number K file) in between instrumentation up to the whole working length. In group B no apical patency file was used in between instrumentation to check for post opciative pain. SPSS versim 22 was used foranalysis. Results: Postoperative pain was significantly less in group-A when compared with group-B, 26 (34.7%) versus 42 (56.0%) with p value 0.009. Moderate pain was observed in 17 teeth (22.7%) of group-A and 21 teeth (28.0%) of group-B. Severe postoperative pain was seen in 3 teeth (4.0%) of group-A and 7 teeth (9.3%) of group-B. Unbearable pain was present in 6 teeth (8.0%) of group-A and 14 teeth (18.7%) of group-B. Conclusion: There was less postoperative pain in asymptomatic irreversible pulpitis teeth with apical patency application during root canal treatment.
