Molar İnsizör Hipomineralizasyonundan Etkilenmiş Daimi Anterior Dişlere Uygulanan Direkt Veneer Restorasyonların Klinik Başarısının ve Ebeveyn Memnuniyetinin Değerlendirilmesi

Abstract

DEMIREL, K. Evaluation of Clinical Success of Composite Resin Restorations Applied Using Direct Veneer Templates for Lesions in Permanent Incisors Affected by Molar Incisor Hypomineralization (MIH). Hacettepe University Health Sciences Institute Specialty Thesis in Pediatric Dentistry, Ankara, 2026. This study aimed to evaluate the 12-month clinical performance of template-assisted direct composite resin restorations applied to permanent anterior teeth affected by molar incisor hypomineralization (MIH). A total of 80 teeth from 45 patients aged 7- 14 years, each presenting with at least one MIH-affected permanent anterior tooth with discoloration and opacity, were included. Composite restorations were placed without tooth preparation using a direct veneer template system. Tooth sensitivity was assessed using the Schiff Cold Air Sensitivity Scale (SCASS). Clinical performance was evaluated at baseline and at 3, 6, and 12 months using modified USPHS criteria. Parent-child satisfaction was assessed at the end of the follow-up period using a 5- point Likert scale. Statistically significant changes over time were observed in marginal adaptation, marginal discoloration, restoration fractures, and wear (p < 0.05). In contrast, no significant differences were found for color match, surface texture, or postoperative sensitivity (p > 0.05). Over the 12-month follow-up period, absolute failure was observed in two restorations (2.5%), both occuring at the 12-month evaluation. Both parents and children expressed high levels of satisfaction, with 95.6% giving combined ratings of 4 or 5 for the overall aesthetic results. Within the limitations of this study, template-assisted direct composite veneers demonstrated a low failure rate over 12 months and may represent a reliable, non-invasive treatment alternative for managing anterior MIH lesions in children.
