Clinical Evaluation of Association of Salivary and Plaque pH with Caries Severity in Children with Molar-incisor-hypomineralization in Haryana: A Cross-sectional Study

European Academy of Paediatric Dentistry (EAPD) Congress in Bergen, the term molar-incisor-hypomineralization was coined by Weerheijm and adopted globally. 5In 2003, MIH was described as IntroductIonEnamel is a tissue that cannot be regenerated, unlike other calcified tissues in the body.Therefore, the changes that transpire during the formation will affect its structure permanently.Thus, enamel defects can be considered to determine the detrimental events that happened during the time of their development. 1Destruction in the enamel organ, which creates changes in tooth enamel, results in the formation of developmental defects of enamel and can be associated with hereditary, acquired, systemic, and local etiological factors.Molar-incisor-hypomineralization (MIH) is a similar developmental defect that alters the normal mineralization, causing permanent damage to the enamel. 1 The clinical appearance was defects involving the occlusal and/or incisal third of one or more permanent molars associated with affected incisors. 2The most vulnerable cell is the transitional ameloblast as it changes from a secretory ameloblast to a maturation ameloblast.These cells may not recover full maturation potential, leading to full-thickness hypomineralization.However, less susceptible cells affected at an earlier or later stage may improve some maturation properties, causing further mineralization in certain regions. 2 Hypomineralization of tooth enamel was noticed as early as the 17th-18th centuries, following an examination of archaeological samples of London cemetery. 3he first epidemiological study evaluating MIH was by Koch in Sweden in the 1970s and was termed "idiopathic enamel hypomineralization." 4 Later, in 2001, at the fifth meeting of the
