The selection and long-term stability of restorative materials for teeth affected by MolarHypomineralization (MH) are controversial. The aim of this study was to compare need for treatmentand status of restorations performed on first permanent molars in patients with and without MH.Retrospective design based on the clinical records of 153 patients who had received comprehensive carein 2014 at the Clinic of the Children’s Comprehensive Dentistry Department (FOUBA) by 3 pediatricdentists (Kappa MH 0.94), and who attended periodical follow-up visits for at least 24 months. Needfor treatment in first molars, and type and longevity of treatment were recorded (modified Ryge criteria/USPHS, Kappa 0.78). Results were compared between patients with MH and without MH. TheKruskal Wallis test was used to compare follow-up time, the asymptotic test was performed to compareproportions, and relative risk (RR) was calculated to compare need for treatment.Mean follow-up times for the 595 teeth analyzed were 61.7±20.1 months for Group without MH, and57.5±23.9 months for Group with MH (p=0.0504). The percentages of teeth requiring at least onetreatment were 7.2% in Group without MH and 27.5% in Group with MH (RR = 3.80, p < 0.001). Of theteeth treated in Group with MH 23.1% required retreatment, while none of the teeth in Group withoutMH did. The need for treatment was approximately 4 times higher in molars affected with MH, withgreater probability of retreatment.
