Prevalence and Severity of Dental Fluorosis among Primary School Children Aged 12–14 Years in Abosied and Alfetehab Localities, Omdurman, Sudan


Background: Dental fluorosis is a disease of dental hard tissues resulting from excess fluoride intake during the developmental stages of teeth causing hypomineralization of the enamel. This study aimed to assess the prevalence of dental fluorosis among school children in Omdurman locality.

Methods: Students in the sixth grade of school were examined to determine the prevalence of dental fluorosis using Dean’s index.

Results: The prevalence of dental fluorosis was 68.3%. The majority of students were diagnosed with very mild (23.2%) and mild (26.5%) forms. There was no difference in the grade of fluorosis between children who were born outside and in Omdurman.

Conclusion: Prevalence of dental fluoride was found to be very high among school children with no difference between males and females.
