Triple Antibiotic Paste vs Simvastatin for Lesion Sterilization and Tissue Repair in Primary Molars.

This randomized, double-blinded, parallel-controlled clinical trial aims to compare the effectiveness of Triple Antibiotic Paste (TAP) and Simvastatin in Lesion Sterilization and Tissue Repair (LSTR) of primary molars with pulp necrosis. A total of 60 children (aged 5-8 years) with non-vital primary molars will be recruited from the Department of Operative Dentistry and Endodontics, Dow International Dental College, Karachi. Participants will be randomly assigned to one of two groups: Group 1 (Control): LSTR using Triple Antibiotic Paste (Ciprofloxacin + Metronidazole + Cefixime). Group 2 (Intervention): LSTR using Simvastatin paste. Both materials will be placed after non-instrumentation cleaning and sealed with glass ionomer cement, followed by stainless steel crown placement. Patients will be evaluated clinically and radiographically at 1, 2, and 3 months post-treatment. Primary outcomes include clinical success (absence of pain, swelling, or sinus tract) and radiographic success (reduction or absence of periapical radiolucency). Data will be analyzed using SPSS v26, with chi-square and t-tests applied as appropriate; p \< 0.05 will be considered significant. This study seeks to determine whether Simvastatin, owing to its antibacterial, anti-inflammatory, and regenerative properties, can serve as a viable alternative to antibiotic-based LSTR in managing necrotic primary teeth.
