Evaluation of Different Medicaments in the Management of Necrotic Primary Molars by Lesion Sterilization and Tissue Repair

Management of non-vital primary molars is challenging due to the natural anatomy of primary teeth, patients' young age, and their behavior toward dental treatment. A simple and effective technique such as Lesion Sterilization and Tissue Repair offers a solution to cases with poor prognosis; however, the medicaments used in this technique have some limitations. This study will evaluate three different medicaments regarding the clinical success, radiographic success, and antibacterial activity.

Inclusion Criteria: * Healthy cooperative children of both sexes in the age range of 4-8 years old. * Children with consenting parents who accept to participate in the study and sign the consent forms. * Children with mandibular primary molars with clinical and radiographic signs of pulpal necrosis. Exclusion Criteria: * Children with hypersensitivity to any of the used medicaments. * Non-restorable teeth without sufficient coronal structure for placement of rubber dam isolation and restoration with stainless steel crowns * Non-restorable teeth with perforated pulpal floor
