This research aims to evaluate the clinical performance and safety of composite dental fillings cured with two different light-curing modes in young children with decayed or insufficiently filled primary molars. The study focuses on deciduous teeth requiring direct filling therapy and seeks to reduce treatment time to improve compliance and comfort for children and dentists. It specifically compares a fast curing mode versus a conventional curing mode in a controlled clinical setting. Participants will receive composite restorations using either a fast curing mode, where the composite is cured for 5 seconds at 2000 mW/cm², or a conventional curing mode, where curing takes 10 seconds at 1200 mW/cm². These treatments will be applied in a split-mouth design, meaning each child will have two molars treated, one with each curing mode. The study will follow participants for 12 months to assess outcomes. During the study, children will be monitored for postoperative pain between 4 and 10 days after the fillings are placed. Researchers will assess the safety and effectiveness of the restorations through clinical performance evaluations. Legal representatives and children must have sufficient language skills to participate, and consent is required. The total duration of participation includes the treatment and follow-up visits over the 12-month period.
