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.
Young, healthy patient, ranging in age from 5-8 years.
Has parents/ guardians who give consent to allow their minor to participate in the study and willing to monitor their progress.
Spontaneous pain or tenderness to percussion.
Deep cavity extending to the pulp chamber.
Uncooperative patients.
Children with a history of allergic reaction with antibiotics.
Teeth with physiological root resorption but root length is more than two thirds, root canal obliteration, severe internal resorption, internal calcifications, or piercing into the bifurcation.
