Lesion Sterilization and Tissue Repair Antibiotic Paste Versus Zinc Oxide and Eugenol Pulpectomy for Treatment of Primary Molars With Pulp Necrosis

Plain-language summary

The goal of this clinical trial is to compare the efficacy of lesion sterilization and tissue repair (LSTR) antibiotic paste versus zinc oxide eugenol (ZOE) pulpectomy for the treatment of primary molars with pulp necrosis in pediatric patients. The main questions it aims to answer are: * Is LSTR antibiotic paste (CTZ paste) effective in treating primary molars with pulp necrosis? * Is ZOE pulpectomy effective in treating primary molars with pulp necrosis, and how does its efficacy compare with LSTR therapy? Researchers will compare LSTR therapy (Group A) with ZOE pulpectomy (Group B) to determine which treatment provides better clinical and radiographic outcomes after six months. Participants will: * Be randomly assigned to one of the two treatment groups after diagnosis of pulp necrosis in primary molars. * Receive treatment under standard behavior management techniques with local anesthesia following topical application of 2% lignocaine gel and rubber dam isolation. * Undergo either Lesion Sterilization and Tissue Repair (LSTR) therapy with CTZ paste or zinc oxide eugenol (ZOE) pulpectomy according to group allocation. * Return for a clinical and radiographic follow-up evaluation after six months to assess treatment outcomes. * Allow researchers to record their clinical findings and radiographic results to evaluate the efficacy of both treatment methods.
