Prevalence of Molar Incisor Hypomineralization Among a Group of Egyptian Children in Fayoum Governorate Schools

Determining the Prevalence of Molar Incisor Hypomineralization Among a Group of Egyptian Children in Fayoum Governorate Schools via clinical examination. Participants from primary and preparatory schools in Fayoum governorate will be included in the study and Clinical examination will be carried out in the school laboratory or an empty class, in day light for both genders. Teeth will be cleaned gently using gauze and wet with saliva during examination. A disposable diagnostic set (mirror, probe) will be used for each patient where mirrors will be used for proper visualization especially for maxillary teeth. Blunt explorers will be used to aid in tactile sensation if needed, as during the differentiation between rough and smooth enamel edges and/or during the inspection of the caries extent if it exists. No diagnostic radiographs will be taken. The results of the study will be regularly monitored by the supervisors who will have full access to these results.
