Abstract
- Aim: To assess the prevalence of Molar Incisor Hypomineralization among a group of
Egyptian children aged from 8-12 years old, in Dakahlia governorate schools.
- . Methodology: The study was carried out on 10% of children aged from 8 to 12 years old
who attended primary governmental schools in Dakahlia governorate. Personal data
including date, name, age, gender, address, school name, as well as the medical history
and any previous dental history were recorded for each child in a custom made
examination chart. Clinical examination was carried out in the school laboratory or an
empty class, in day light. Teeth were cleaned gently using gauze then wet with saliva
during examination. A disposable diagnostic set (mirror, probe) was used for each patient
to examine 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 criteria and scores were recorded in the chart. No diagnostic
radiographs were taken.
- Results: The results of the present study showed that the MIH prevalence was (5.8%)
among 52968 examined Egyptian children in Dakahlia governorate schools,51.5% (1588)
were females while 48.5% (1496) were males, the mean age for males and females were (10.2)
and (10.1) years respectively, Regarding the severity of MIH, (51.6%) of all the affected
incisors were mild and (48.2%) had no defect, while for affected first permanent molars,
about (72.04%) were mild, (5.9%) moderate and (21.5%) were severe.
- Conclusion: Prevalence of MIH in a 10% of children aged from 8 to 12 years old who
attended primary governmental schools in Dakahlia governorate was (5.8%), Molars were
the most prevalent teeth affected. Females are more frequently affected by MIH than
males. The most prevalent degree of severity of MIH was “mild” followed by “severe”
then “moderate” among all the affected teeth.
