This research aims to evaluate the clinical performance and safety of two different curing modes for composite resin restorations in primary molars of young children. The study focuses on children aged 4 to 9 years who need direct filling therapy on deciduous teeth. Dental treatment in young children is challenging due to anxiety and difficulty in moisture control, so reducing treatment time could benefit both children and dentists. Participants will receive composite restorations cured using either a fast curing mode, which takes 5 seconds at 2000 mWcm, or a conventional curing mode, which takes 10 seconds at 1200 mWcm. This is a randomized, double-blind, split-mouth clinical trial lasting 12 months. Each child will have two different molars treated with each curing mode in separate quadrants. During the study, children will be monitored for postoperative pain 4 to 10 days after treatment. The trial involves legal representative consent, assessments of treatment performance and safety, and evaluations of any complications or discomfort. The total participation time covers the full 12-month follow-up period to assess the long-term outcomes of the dental restorations.
