Abstract :
MIH is defined as a qualitative enamel defect from systemic origin. It affects one to four permanent first
molars and can affected also the permanent incisors with variable severity.
Nowadays, the aetiology is unknown and there is a wide range of prevalence of MIH. Therefore, the early
detection of the lesions offers to set up appropriate means of prevention as quickly as possible. Besides
etiopathogenic investigations, this work is highlighting the therapeutic approach of MIH in children and
adolescents. Preventive guidelines are invoked to extract sensibility and remedy either the high risk of caries
or functional problems encountered most often.
