Background/Aim: This study aimed to evaluate the 36-month clinical performance of molars affected by molar incisor hypomineralization (MIH) and carious lesions. Two distinct restorative approaches following selective caries removal were employed. The split-mouth design focused on assessing the clinical success and survival of glass hybrid (GH) and direct composite with short fiber-reinforced composite (SFRC) in permanent first molars affected by MIH.
Methods: Thirty-one children aged 6 to 12 years (18 female, 13 male) at least two carious permanent first molars diagnosed with severe MIH were randomly assigned as follows: group one equals GH (Equia Forte®HT) and group two equals SFRC (EverX FlowTM) covered by micro-hybrid composite (G-Aenial®posterior composite). Sixty-two molars were restored in a split-mouth design. For selective caries removal, only disorganized dentin in the pulpal and the axial wall was removed using low-speed tungsten carbide burs and hand instruments. The durability of the restoration was assessed based on modified United States Public Health Service (USPHS) criteria at the initial evaluation and subsequent follow-ups at 6, 12, 24 and 36 months post-treatment.
Results: Over the 36-month observational period, eight Glass Hybrid (GH) and four Short Fiber-Reinforced Composite (SFRC) restorations experienced failure. The clinical success of both restoration types exhibited a statistically significant decline over time (p<0.001 for both). When incorporating variables such as restoration type, sex, age, tooth type, and time into the analysis model, it was determined that the risk of failure for restorations on the left lower first molar was statistically significantly higher than that of the left upper first molar (p<0.002).
Conclusion: Composite restorations employing Short Fiber-Reinforced Composite (SFRC) and Glass Hybrid (GH) demonstrate similar clinical success when utilized in the selective caries removal approach for managing permanent molars affected by molar incisor hypomineralization.
