Silver Nanoparticle-Coated Orthodontic Brackets for Preventing Enamel Demineralization

The goal of this clinical trial is to learn whether orthodontic brackets coated with silver nanoparticles can help prevent early damage to tooth enamel in people receiving fixed braces. The main question it aims to answer is: -Do silver nanoparticle-coated brackets help reduce enamel demineralization (the early stage of tooth decay) compared with standard stainless steel brackets? Researchers will compare silver nanoparticle-coated brackets with standard stainless steel brackets. Each participant will receive both types of brackets on different teeth so that the results can be compared within the same person. Participants will: * Receive fixed orthodontic treatment as planned. * Have both silver nanoparticle-coated and standard stainless steel brackets placed on different teeth. * Attend routine orthodontic appointments. * Have premolar teeth that were already planned for extraction as part of their orthodontic treatment removed after one month so researchers can examine the tooth enamel around the brackets.

Inclusion Criteria: * Patients scheduled for fixed orthodontic treatment requiring premolar extraction * No history of previous orthodontic treatment done * Intact enamel surface of the premolars to be extracted Exclusion Criteria: * Non-extraction cases * Patients with previously done orthodontic treatment * Enamel surface defects on the premolars to be extracted(caries, hypoplasia, cracks etc.)
