Demarcated hypomineralization lesions: Prevalence, defect characteristics and OHRQoL among a subpopulation of Saudi children attending King Khalid University outpatient dental clinics

Abstract

Demarcated hypomineralization lesions of enamel (DHL) are qualitative developmental abnormalities of dental enamel, described morphologically as well-defined areas of hypomineralization. Two distinct entities of DHL have been demonstrated: Molar Incisor Hypomineralization (MIH) and Hypomineralized Second Primary Molars (HSPM). To date, very few prevalence studies of DHL exist in the Arab and Saudi regions.
