Abstract


An idiopathic qualitative defect of enamel, affecting one or more of the permanent molars with/without permanent incisors is known as Molar Incisor Hypomineralization (MIH). Similar defect on primary second molars is termed as
deciduous molar hypomineralization (DMH). Case report and Conclusion: The prevalence rate of MIH and DMH worldwide is between 2.4%-40.2% and 4.9%-9.0% respectively. Clinically, these defects appear as white, yellow or brown spots, and surface is smooth with normal thickness of the enamel. Lack of quality in the enamel causes porosity that fractures easily under mastication, exposing the dentin, and further allows progression of caries. Hence, this
condition should be diagnosed as early as possible for providing a preventive management against caries and avoid post eruptive breakdown. In addition, intervention with full coverage restoration is needful in the management of the affected teeth. Preformed metal crowns (PMCs) are recommended as the best full coverage restoration for managing primary molar teeth. The Hall Technique embraces changing concepts of managing, without local anesthesia, caries
removal or tooth preparation. Management of teeth with DMH is challenging as it is quite difficult to achieve anesthesia and due to hypersensitivity, the co-operation of the child is questionable.
