Comparing the postoperative pain resulting after mechanical instrumentation using M-pro files versus that resulting after using ProTaper Next rotary files in lower molar with symptomatic Irreversible pulpitis molars.
Lower molars with symptomatic Irreversible pulpitis molars are selected according to the eligibility and exclusion criteria and patients are then randomized to receive treatment either using M-pro Files or ProTaper Next files. Postoperative pain is then assessed using the Numerical Rating scale 6, 12, 24, 48 and 72 hours post-operatively . After completing the treatment, patients will instructed to take placebo if they feel pain and will be asked to provide the quantity of placebo intake until 72 hrs. In case of pain not relieved by placebo, after recording the amount of pain, the patient will be instructed to take an alternative line of pain control (Ibuprofen 400mg tablets every 6 hours). The amount and frequency of Ibuprofen intake will be recorded.
