This study aims to assess the effect of Calcium Hypochlorite Versus Sodium Hypochlorite as Root Canal Irrigants on Postoperative Pain and Bacterial Reduction in Mandibular Premolars with Necrotic Pulps.
Systematically healthy patient (ASA I, II).
Age between 20 and 55 years
Male or female.
Mandibular premolar teeth having single canals diagnosed with pulp necrosis with asymptomatic apical periodontitis.
Medically compromised patients having significant systemic disorders. (ASA III or IV).
History of intolerance to NSAIDS.
Immature roots
Vital pulp tissues.

Effect of Calcium Hypochlorite Versus Sodium Hypochlorite as Root Canal Irrigants on Postoperative Pain in Mandibular Premolars with Necrotic Pulps.
measuring tool: Numerical Rating Scale (NRS). Unite of measurement: Categorical None 0 Mild 1-3 Moderate 4-6 Severe 7-10 Time of measurements: At 6, 12, 24, 48- hours post-treatment.
Effect of Calcium Hypochlorite Versus Sodium Hypochlorite as Root Canal Irrigants on Bacterial Reduction in Mandibular Premolars with Necrotic Pulps.
Intracanal bacterial load reduction will be determined by bacterial counting using agar culture technique after root canal preparation (CFUs/ml), The growth will be semi quantitatively determined as very heavy, heavy, moderate, sparse and very sparse depending on the CFU ranging from \>100,000,˂100,000,˂10,000,˂1,000, ˂100 colony forming unit per 1 ml BHI respectively.
Number of analgesic tablets taken by the patient after endodontic treatment
Number of analgesic tablets taken by the patient after endodontic treatment Up to 48 hours postoperative. Measuring tool: counting Measurment unite: numerical.
