Young patients may complain about the unesthetic appearance of their affected incisors.5
The bonding to enamel is difficult and risky in such case, because of the prismatic morphology in the porous enamel is altered; as a result the loss of the defective restoration and frequent re-treatments. 17, 20
The use of antibiotic is also suggested to be involved in this disease. 1, 3, 4, 7, 10, 14, 16, 19, 20 There is about a 2-fold increase in risk of MIH if amoxicillin is used in the first year of life. (Lygidakis et al. 2010)
