Summary

This study aims to assess the impact of occlusal reduction on post-operative pain after single-visit root canal treatment in patients with necrotic pulps or previously initiated (accessed).

Detailed description

A randomized clinical trial will take place at the postgraduate endodontic clinic department at JU Hospital to assess the effect of occlusal reduction on post-operative pain. Participants will be enrolled from the pool of patients referred to the department of endodontics at JUH for root canal treatment, and the trial will be carried out on those diagnosed with necrotic pulps or previously initiated (accessed) teeth. Patients will undergo root canal treatment by postgraduate students, under rubber dam, and using the dental operating microscope. At the completion of endodontic treatment, the numbered, sealed, randomization envelope will be opened by the operator, and patient allocation will be revealed. Access cavity will be sealed with Glass ionomer restoration, then patients will be allocated to either undergo occlusal reduction (Intervention group) where all occlusal contacts on the functional and non-functional cusps as well as on the marginal ridges will be reduced using a diamond bur, or not undergo occlusal reduction (Control group) where all occlusal contacts will remain intact. The presence or absence of contact will be confirmed using articulating paper where occlusal surfaces will be dried and articulating paper will be held between the teeth with the mandible guided to the centric position. Intact occlusion will be assessed by examining the marks on the teeth. A high-speed handpiece with copious coolant will be used to remove occlusal contacts (Intervention group) or just moved above the surface of the tooth without contacting the occlusal surface (Control group) to facilitate patient blinding. The patient will be told to not change his or her restoration to a permanent restoration for at least a week (before the completion of data collection). Treatment will be completed in a single visit. Pain will be assessed according to a visual analog scale (VAS). Scores will be taken before commencing the procedure (pre-operative pain) and after the treatment at different time intervals; 6, 24, 48 hours, and 1 week after. This will be done by calling the patients by phone to record the degree of pain at these intervals. The assessment of postoperative pain will be performed by a researcher-examiner blinded to the carried-out treatments.
