ABSTRACT
The objective of this study is to evaluate post operative pain in single and multi visit endodontics therapy with rotary instrument. This study may help the clinicians to decide to complete the RCT in one visit. Experimental Study. This study was conducted in Department of Operative Dentistry LUH Hyderabad, from July 2010 to Jan 2011. This study was performed to compare post obturation pain following single and multiple visit root canal treatment [RCT] with rotary instruments. Sample size was sixty six permanent anterior teeth which were divided into Group A [Single visit] and Group B [Multiple visit] with 33 teeth in each group. After taking informed written consent routine RCT steps were carried out like access opening, canal path finding, and radiographic working length determination. Canal preparation was done by Pro Taper rotary files up to F2 size file with 2.5% sodium hypochlorite irrigation. In Group A obturation was done at same visit lateral condensation and in Group B, after canal preparation calcium hydroxide as intra canal medication was given for 7 days. Then the canal was obturated by lateral condensation technique and temporized with cavit. The patients were recalled at three specific post obturation periods, after 24 hours, 7 days and one month and were evaluated to determine pain severity on verbal rating scale. Chi Square test and Fridman test were used to interpret the results. The results of present study indicated almost same degree of post obturation pain in both groups
