简要总结
This study is about the long-term survival success of different, externally prepared fillings (Indirect restoration, CAD-CAM blocks) used in teeth with reduced mineral structure, namely Molar Incisor Hypomineralization (MIH), which is called chalk teeth in children.
详细描述
The aim of this study was to comparatively evaluate the long-term survival times and clinical success of nano-ceramic hybrid CAD-CAM blocks, Grandio Blocs (R) (VOCO), and glass-ceramic blocks, GC INITIAL LiSi (GC AMERICA INC. USA), according to USPHS criteria, after pulpal treatment in mandibular teeth with bilateral moderate molar incisor hypomineralization.
