Pak Oral Dental J Jan ;36(4):645-9.

The objective of this study was to establish whether addition of a 2% chlorhexidine as final rinse to a conventional treatment protocol decreases the post- operative discomfort after single-visit endodontic treatment. The study was performed at the Department of Operative Dentistry, Institute of Dentistry, Liaquat University of Medical & Health sciences (LUMHS) Hyderabad / Jamshoro. Sixty cases were included in this study by using simple random sampling technique. There were two groups of the patients Group A (patients in which root canals were rinsed with 2% Chlorhexidine solution (GLUCO-CHEX 2% PPH CERKMED PLAND) for 5 minutes before obturation) and Group B (patients in which root canal treatment completed with conventional protocol). The level of pain was measured preoperatively and for 7 days postoperatively on visual Analog Scale. A proforma printed with VAS was given to the patients to mark the level of pain at the end of each day for 7 days. Data were entered and analyzed by SPSS Version-17.The mean age of the patients was 33.03±10.22. The males and females were 35% and 65% respectively. In group A, the pre-operative pain status showed the severe pain observed in 32% patients; Post-operative pain status after 24 hours (Day-1) showed the severe pain observed in 13% patients, after 72 hours showed the severe pain observed in 2% patients, after 168 hours (Day-7), the severe pain was not observed. It is concluded that the patients on the Chlorhexidine rinse appeared to show a greater decrease in pain levels over the observation period when compared to the control group.
