Clinical trials

The goal of this clinical trial is to compare the clinical performance of chemically-cured and light-cured bulk-fill composite materials used for Class II restorations in children aged 4 to 9 years with primary second molars. The main questions it aims to answer are: What are the clinical success rates of the restorations at 12 months based on modified FDI criteria? How do the two materials compare regarding application times, clinician ease of use, and patient satisfaction? Researchers will compare the chemically-cured bulk-fill composite (Stela Capsule) to the light-cured bulk-fill composite (Filtek One) using a split-mouth design to see which material provides better long-term clinical performance and survival rates. Participants will: Receive two different bulk-fill composite restorations in matched primary second molars within the same dental arch Visit the clinic for routine checkups and evaluations at 1 week, 3 months, 6 months, 12 months, 24 months, and 36 months
