Overview

The study will aim to evaluate the postoperative pain and bacterial load after application of two intracanal medications in mandibular first molar teeth with necrotic pulp. Methods (Participants, Interventions, and Outcomes) Study Setting: This randomized clinical trial will include 36 patients, equally allocated into three groups (12 patients each). Participants will be recruited from the Outpatient Clinic of the Endodontic Department, Faculty of Oral and Dental Medicine, Future University in Egypt. All treatments will be performed by a postgraduate master's degree candidate using a Ritter dental unit (Germany) and Sirona digital intraoral radiography (Nanopix, size 2). Eligibility Criteria: Eligible participants will be 18-40 years old with necrotic pulp and symptomatic apical periodontitis in restorable mandibular first molars (Type III mesial and distal canals) and willing to participate. Exclusion criteria include pregnancy, systemic diseases, recent use of analgesics or antibiotics, bruxism or clenching, severe traumatic malocclusion, and teeth with periapical radiolucency, root resorption, pulp stones/calcifications, or previous endodontic treatment.

Interventions

Root canal treatment with intracanal medication by calcium hydroxide for one week.DRUG

Following cleaning and shaping of the root canal, calcium hydroxide paste will be used as an intracanal medicament for one week to reduce bacterial load before the final root canal

Following cleaning and shaping, no intracanal medicament will be used. The root canal will be obturated according to the study protocol.
