Background/Aim. Developmental disorders of teeth are the problems that are
becoming more present in pediatric dentistry, especially on first permanent
molars and incisors. Molar Incisor Hypomineralization (MIH) is proposed term
for this phenomenon. The aim of this study was to establish the MIH
prevalence in children living in the Foča municipality (Bosnia and
Herzegovina) as well as to assess characteristics and expression of
hypomineralization within the tested population. Methods. A total of 141
children from the Foča municipality, 8 years of age, were included in this
study. Criteria according to Weerhejm have been used for diagnosis of
hypomineralization: demarcated opacity (DO), post-eruptive breakdown (PEB),
atypical restoration (AR), extracted molars due to MIH (E-MIH) and unerupted
tooth (UT). Level and the prominence of color changes have been determined
for patients with DO, PEB and AR. Results. MIH in this area was present in
12.8% of children. The prevalence of MIH changes expressed in percentages was
as follows: DO was at 9.2%, PEB in 3.5%, AR in 5.6%, while E-MIH was 5.6%. A
total of 9.9% of the examinees had mild, 5.6% moderate, and 7.8% severe form
of MIH. White form of MIH defects was found in 9.9% of the examinees,
white-yellow one in 5.6% and yellow-brown color in 3.5% of the examined
children. These changes were more often present in the lower jaw (60.3%). In
total, 6.4% of children had these changes present only on molars, while 6.4%
of them both on molars and incisors simultaneously. Conclusion. A total of
12.8% of the examinees with MIH is not to be disregarded. With timely
diagnosis, prevention and therapy complications could be avoided or
mitigated.
