Clinically compare the post-operative pain , incidences post-operative swelling , post-operative number of analgesic tablets taken by patient and amount of bacterial load reduction after using 50% Commiphora Myrrh Chemomechanical preparation , versus 2.5% NaOCl,in asymptomatic necrotic mandibular premolar treated in single visit.
The patients will be randomly divided into 2 groups. Intervention group (50% Commiphora Myrrh solution root canal irrigant) and control group (2.5% sodium hypochlorite root canal irrigant)
Post-operative pain will be measured at 6,12,24,48 hours post-operatively The pain will be recorded using numerical rating scale
Post-operative swelling will be measured at 6,12,24,48 hours post-operatively The swelling will be receded using visual swelling rating scale
Number of analgesic tablets taken by the patient post-operatively. Up to 48 hours
Amount of bacteria load reduction The intracanal bacterial load reduction will be determined using agar culture technique by counting the colony forming units per milliliter (CFI /ml) before and after root canal preparation.
