Clinical Comparison of CAD/CAM Nanohybrid Composite and Hybrid Ceramic Overlays in Children With Molar-Incisor Hypomineralisation

This clinical study was conducted to compare two different dental materials used in the treatment of children who have a condition called molar-incisor hypomineralization (MIH). MIH affects the quality of the enamel in permanent molars and can cause sensitivity, pain, and rapid tooth breakdown. In this study, children between the ages of 8 and 13 who had MIH in at least two molars received two types of onlay restorations: one made from a hybrid composite block and the other from a hybrid ceramic block. Both restorations were designed and manufactured using a digital system called CAD/CAM, which allows for more precise and efficient dental treatment. Each child received both types of restorations-one on each side of the mouth-in a split-mouth design. The goal was to see how well each material worked over a period of six months. The restorations were evaluated by trained dentists using clinical criteria, and the children were also assessed for tooth sensitivity using a cold air test. The main purpose of this study was to find out which material provides better clinical performance and reduces tooth sensitivity more effectively.
