Abstract

BACKGROUND:

Molar incisor hypomineralization (MIH) is frequent in children and etiology is different.

AIM:

The aim of this study was to determine the prevalence, severity, and risk factors of MIH and to investigate the relationship between the severity of the defect in the teeth affected by MIH and the risk factors.

DESIGN:

The study included patients at the age range of 9 and 10 years, who were admitted to the clinic of paediatric dentistry in Dokuz Eylul University and had four-first molar teeth (FMT) and eight incisor teeth eruptions in the jaws. The presence of only demarcated opacities in one or several FMT and incisor teeth was defined as MIH1, and the presence of post-eruptive breakdown (PEB), atypical restorations, and extracted teeth was defined as MIH2.

RESULTS:

MIH was detected in 142 (11.5%) of 1237 children. Although there was no statistically significant difference between upper and lower FPM and the occurrence of MIH (P < 0.902), there was a difference between upper and lower central and lateral teeth (P < 0.001; P < 0.009). A significant difference was detected between birth week, birthweight, high fever, and asthma/bronchitis and MIH1 and MIH2 (P < 0.001).

CONCLUSION:

The prevalence of MIH was found to be 11.5%. It was observed that the patients undergoing low birthweight, preterm delivery, high fever, and asthma/bronchitis were more severely affected by MIH.
