摘要：The aim of our study was to
monitoring the prevalence of the First Permanent Molar and Incisor
Hypomineralisation Syndrome (MIH) in schoolchildren from Iasi. Materials and methods. The surveyhas
been carried out on a number of 681 children aging from 8 to 11: 401 girls
(58.9%) and 280 boys (41.1%). The Enamel Defect Index (EDI) was used in order to
classify data. Results and
discussion. Our study showed a prevalence of enamel development in permanent incisors of 10.28% and
in first permanent molars of 4.26%.
The prevalence of MIH Syndrome was 14.54%, a quite high value, explained
by the low fluoride concentration in the studied area. The enamel defects in
permanent incisors had a RR of 2.41
( 1.59 - 3.67 CI 95% ). The
prevalence of defect emergence in the first permanent molars is more probable if
the affected incisors have a lower prevalence (r= - 0.50). Conclusions. Our study revealed a MIH
Syndrome prevalence of 14.54%. The correlation between the permanent incisors and the first permanent
molars was r = - 0.50 and on the mandible r = 0.22. The ratio of affected first
permanent molars compared to the incisors was of 1/4.
