Molar-incisor hypomineralization (MIH) is a qualitative enamel defect, in which molars and incisors involved are prone to post-eruptive enamel breakdown leading to sensitivity, and caries. Atraumatic/Alternative Restorative Treatment (ART) is a minimally invasive procedure. It can be very beneficial in managing MIH-affected molars in communities with limited access to dental care. Zirconia-reinforced GI was recently introduced. It is claimed to serve as a long-term temporary restoration until a more permanent restoration is placed

| Change in clinical success rate | It will be assessed using Modified ART criteria, restorations receiving a score of: (0) Restoration is present and satisfactory OR (1) Restoration is present, slight defect at the cavity margin of less than 0.5 mm; no repair is needed. will be considered successful, and any other score will be considered a failure. | at 3 months, 6 months, 9 months, 12 months |
| Measure | Description | Time Frame |
|---|---|---|
| Change in pain | Pain will be recorded using VAS Using a visual analog scale (VAS), the subjects were instructed how to point to the position of the line between faces to indicate how much painthey might feel. In this system, the total scores range from 0 to 100 based on measuring the distance in millimeters from the left end bar to the mark made by the child on the 10 cm line anchored by happy to sad faces, with a higher score indicating more severe pain. |

| Change in sensitivity | sensitivity will be recorded using VAS by performing air blast test Using a visual analog scale (VAS), the subjects were instructed how to point to the position of the line between faces to indicate how much pain they might feel. In this system, the total scores range from 0 to 100 based on measuring the distance in millimeters from the left end bar to the mark made by the child on the 10 cm line anchored by happy to sad faces, with a higher score indicating more severe pain. | at 1 week, 3 months, 6 months, 9 months, 12 months |
