Evaluation of Pain Relief and Bacterial Reduction After Using Calcium Hydroxide With Mesoporous Silica Nanoparticles as an Intracanal Medicament in Necrotic Mandibular Molars: A Randomized Controlled Clinical Trial
Egypt42 participantsStarted 2025-09-01
Plain-language summary
This study compares how well different root canal medications reduce pain and bacteria after treatment of lower molar teeth with necrotic pulp. It tests whether adding mesoporous silica nanoparticles-antibacterial particles-to calcium hydroxide makes the treatment more effective. Forty-two adult patients will be randomly assigned to receive either calcium hydroxide alone, nanoparticles alone, or a mix of both for one week during root canal therapy. measure patients' pain levels after 6h,12h,24,48h and 72 hours from treatment and the number of bacteria before and after treatment to see which method gives the best results. The goal is to make root canal treatments more comfortable and successful for future patients.
