Evaluation of Post-operative Pain and Bacterial Load Reduction After Application of Three Intra-canal Medications (Cocoa Husk Versus Calcium Hydroxide With and Without Cocoa) in Necrotic Mandibular First Molar.
Evaluation of Post-operative Pain and Bacterial Load Reduction After Application of Three Intra-canal Medications (Cocoa Husk Versus Calcium Hydroxide With and Without Cocoa) in Necrotic Mandibular First Molar.
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.
Inclusion Criteria:1. Patients with an age range between 18 to 40. 2. Patients with necrotic pulp. 3. Restorable teeth. 4. Positive patient acceptance for participating in the study. 5. Type III distal and mesial canal of the first mandibular molar. 6. Patients have necrotic pulp with symptomatic apical periodontitis in mandibular first molars.
