Considered as significant if p-value < 0.05. Abbreviations: CPQ = Child Perceptions Questionnaire, CI = Confidence Interval, DIFF Test= Paired difference test. * Anterior-Group was defined as any affected hypomineralized incisor or canine, which might have also included a asymptomatic MIH molar. Posterior-Group was defined as any molar, which was affected by MIH. Control-Group patients had no MIH teeth at all.
