ABSTRACT
The objective of the study was to compare the post instrumentation pain in teeth undergoing root canal treatment with or without occlusal tooth reduction. This randomized control trial was conducted at Outpatient Department of Operative Dentistry at Altamash Institute of Dental Medicine from September 2011 to March 2014. A total of 402 patients with irreversible pulpitis and normal periapical radiographic appearance of posterior teeth were included in this study. Patients were randomly allocated into two groups i.e occlusal tooth reduction [OTR] group and no occlusal tooth reduction [NOTR] group. After root canal instrumentation, patients were instructed to complete a Visual Analogue Scale [VAS] to score their pain at 6 hours, 12 hours, 18 hours, 24 hours, 2 days, 3 days, 4 days, 5 days, and 6 days. The final outcome that is mean post instrumentation pain score was measured at 6 days of post instrumentation.

After root canal instrumentation, patients were instructed to complete a Visual Analogue Scale [VAS] to score their pain at 6 hours, 12 hours, 18 hours, 24 hours, 2 days, 3 days, 4 days, 5 days, and 6 days. The final outcome that is mean post instrumentation pain score was measured at 6 days of post instrumentation. Mean post instrumentation pain score at 6 days was significantly low in OTR group than NOTR groups [2.44 +/- 0.86 vs. 3.24 +/- 0.89; p=0.0005]. Thus, it is concluded that occlusal reduction help in the prevention of post instrumentation pain in teeth with irreversible pulpitis, sensitivity to purcussion, pre- treatment pain and absence of periradicular radiolucency. Whereas the presence of all four conditions are the strong predictors, the presence of any one or more of the conditions is enough to indicate a need for occlusal reduction
ABSTRACT
Objective: To compare the mean difference in inter-appointment pain by using ledermix and no intracanal medicament in patients with acute apical peridontitis
Material and Methods: This Randomized control trial was conducted at Operative dentistry department of Altamash Institute of Dental Medicine, Karachi during August 2009 to February 2010. Patients after selection were divided into two groups by even-odd method. Group 1: ledermix paste and Group 2: no intracanal medicament [control group]. The follow-up visit was scheduled and the Mean inter-appointment pain was recorded after 48 hours on visual analogue scale
Results: In 222 patients mean inter appointment pain was 9.0+/-0.71 in group 1 and 12.26 +/- 0.90 in group 2. The mean difference between groups 3.26 +/- 1.15 [95% CI of mean: 0.99 to 5.53]
Conclusion: Patients with ledermix paste experienced significantly less postoperative pain than with no intracanal medicament [p=0.005] at 48 hours
