MOLAR INCISOR HYPOMINERALIZATION AND CELIAC DISEASE.

BACKGROUND

Molar incisor hypomineralization (MIH) is a developmental enamel defect with multifactorial etiology. Although the relationship between celiac disease (CD) and developmental enamel defect was demonstrated, the association between CD and MIH is uncertain.

OBJECTIVE

The objective of this study was to analyze the occurrence of MIH in CD patients.

METHODS

Forty CD patients and a control group with 40 healthy individuals were selected. A calibrated examiner (k≥0.889) according to the European Academy of Pediatric Dentistry criteria performed the diagnosis of MIH. Data were analyzed by descriptive statistics and Fischer's exact test (α=0.05).

RESULTS

Of the 80 participants, ten presented MIH with eight individuals with CD. Celiac patients presented 4.75 times the chance of occurrence of MIH than the control group (95% CI: 2.22-10.18; P=0.044). In all the evaluated teeth (n=978), 22 had MIH: 20 teeth in individuals with CD and two in those without the disease. All CD participants with MIH presented the classic form of the disease. CD participants showed 17 teeth (85.0%) with demarcated opacities, two (10.0%) post-eruptive collapses and one (5.0%) atypical restoration. The control group presented only demarcated opacities.

CONCLUSION

CD increased the chance of MIH and associated with its clinical manifestations can assist in the diagnosis of CD.
