"Clinical Evaluation of Self-Assembling Peptides Versus Tri-Calcium Phosphate Based Varnish in Treatment of White Spot Lesions; Split-Mouth Randomized Clinical Trial"

Brief Summary: This randomized controlled clinical trial will evaluate the effectiveness of two remineralizing agents in the treatment of white spot lesions (WSLs) in young adults. White spot lesions are early signs of enamel demineralization that commonly develop after orthodontic treatment. The study will compare a self-assembling peptide-based varnish (Curodont Repair, SAP P11-4) with a tri-calcium phosphate-based varnish (Clinpro White Varnish, 3M) using a split-mouth design. A total of patients aged 15-25 years with at least one eligible WSL on each side of the anterior teeth will be enrolled. Each patient will receive Curodont Repair on one side and Clinpro White Varnish on the contralateral side. Treatments will be applied at baseline and repeated after 3 months. Lesions will be evaluated using standardized digital photography, ICDAS II scoring, lesion size measurements, and patient satisfaction questionnaires at baseline, 3, 6, and 9 months. The primary outcome is the change in color of white spot lesions over 9 months. Secondary outcomes include changes in lesion size, ICDAS scores, and patient-reported satisfaction. The study is double-blinded (patients and outcome assessors) and conducted at the Faculty of Dentistry, Ain Shams University.
