Clinical Trial Summary

The aim of this study is to assess the prevalence of MIH among a group of Egyptian children aged from 8-12 years old in Dakahlia governorate schools.

Clinical Trial Description

• Clinical examination will be carried out in the school laboratory or an empty class, in day light, 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.

• An examination chart (Appendix 1) will be filled for each child including: date, name, age, address, gender, school, medical health and any previous dental treatment, followed by clinical examination to the four first permanent molars and the eight maxillary and mandibular incisors to detect the presence of MIH and its severity based on European Academy of Pediatric Dentistry (EAPD) criteria . To diagnose Molar Incisor Hypomineralization, at least one affected first permanent molar is required. Extracted first permanent molar will be recorded as affected if another first permanent molar has a defecting MIH

• Each child affected with MIH will be given a letter outlining his dental health status, to inform the parents and indicate the need for treatment.
