Design outcomes

Primary

Measure	Time frame
It is expected that there will be no association between Molar-Incisor Hypomineralization and facial growth pattern. The data from this research will be analyzed descriptively and analytically. To assess the association between facial growth pattern and the presence of MIH, the chi-square test will be performed in a 3 x 2 contingency table. All statistical tests will be performed using the Statistica program, and results will be considered statistically significant for p < 0.05	—
