Comparison of Post Instrumentation Pain Score in Irreversible Pulpitis with Occlusal Reduction Versus No Occlusal Reduction

Abstract

To compare the effect of occlusal reduction on post instrumentation endodontic pain. It is essential in endodontics to control pain during root canal treatment. Several techniques including pre-operative analgesics, corticosteroid preparation, use of anaesthetics and reducing the occlusal surface of tooth can be used for controlling pain in endodontic therapy. The reduction of occlusal surface of tooth is a simple procedure to reduce pain during endodontic therapy. METHODOLOGY: This quasi experimental study was conducted in department of Operative Dentistry, at Fatima Memorial Hospital, Lahore from September 2017 to March 2018. Total Hundred patients of both genders with irreversible pulpitis in posterior teeth and no to mild tenderness to percussion were chosen by non-probability consecutive sampling. After use of local anesthesia, canal preparation was done, and calcium hydroxide dressing were placed in all canals. All patients were indiscriminately allocated in two groups i.e. Occlusal reduction group (Group A) and Group without occlusal reduction (Group B). Pre-operative pain before start of procedure and post-operative pain 6 days after instrumentation were recorded on visual analogue scale. The final result was mean post instrumentation pain value for both groups recorded at 6 days after instrumentation. Data was evaluated by Independent sample t-test at p < 0.05 considered as significant. RESULTS: There was no significant difference in the mean pain scores between the two groups. (Group A 1.2 ±0.926, Group B 1.38 ±1.176, p>0.05). CONCLUSION: Occlusal reduction did not influence occurrence of post instrumentation pain in irreversible pulpitis cases.
