Validity and reproducibility testing of the Molar Incisor Hypomineralisation (MIH) Index
International Journal of Paediatric Dentistry Oct 26, 2018
Ghanim A, et al. - The current study explored the reproducibility and validity of results from a new instrument developed to evaluate molar incisor hypomineralisation (MIH). Using Cronbach's alpha, inter-rater and test-retest reliabilities were examined. For the presence/absence of MIH and other enamel defects using the new index, 35 oral health professionals scored clinical photographs. In clinical presentation and lesion extension, researchers achieved “substantial” to “almost perfect” levels of agreement. They observed that the tested MIH index had reasonably solid properties, supporting that it is a reliable and valid instrument for use in population-based and clinical screenings for diagnosis of MIH and other enamel defects.
