This book is a wide-ranging reference on current clinical and scientific knowledge regarding the various aspects of molar incisor hypomineralization (MIH). Background information is first presented on the structural properties of hypomineralized enamel, the prevalence of MIH, and potential etiological factors. Subsequent chapters focus on key considerations in clinical practice. Diagnostic criteria, classifications, and treatment strategies are discussed and detailed attention is devoted to potential associations between MIH and caries, the occurrence of hypomineralized primary teeth, and the knowledge and experience of dentists concerning MIH. In the last part of the book, the different treatment options are systematically presented and reviewed, covering pain control, prophylaxis and desensitization, fissure sealing, direct and indirect restorations, and extraction therapy. The cost-effectiveness of the available procedures is also considered. The book is written by acknowledged international experts in the field and will be an ideal source of up-to-date information and guidance for both dental professionals and postgraduate students.
