This randomized, triple-blinded clinical trial aims to evaluate the effect of preemptive analgesia using ibuprofen on pain perception and anxiety during restorative treatment of first permanent molars in children diagnosed with molar-incisor hypomineralization (MIH). MIH-affected teeth often present with hypersensitivity, difficulty in achieving adequate anesthesia, and increased dental anxiety, which complicates dental treatment. Participants aged 6-12 years with MIH will receive either ibuprofen syrup or placebo 30 minutes before treatment. Pain will be assessed using the FLACC Behavioral Pain Scale and Wong-Baker FACES scale, and anxiety will be evaluated through heart rate and oxygen saturation. The results will determine whether preoperative ibuprofen reduces intraoperative pain and improves anxiety control in this population.

4. No cavitated lesion is related to the defect of previous restorative or preventive treatment.
Exclusion Criteria

2. Loss of tooth structure due to caries.
3. intolerance to ibuprofen.
4. developmental defects, including amelogenesis imperfecta and dentinogenesis imperfecta.
