Esthetic rehabilitation of first permanent molars affected with severe form of Molar Incisor Hypomineralization using indirect composite onlays-A case series

Restorative management of MIH affected young permanent first molars is often challenging for pediatric dentists. Poor patient compliance, extreme sensitivity, rarity of the condition and increased treatment costs are some of the factors compounding its management. Traditionally, Stainless Steel and Cast Metal crowns have been the mainstay for management of these molars. However, young age of patients and demand for esthetics necessitates the search for an esthetic and conservative alternative. Present case series aims to highlight the use of minimally invasive Indirect Composite Onlays for rehabilitation of ten permanent molars affected with severe form of MIH in children, aged 8-14 years. At 30-36 months (x̅ 34.8 mths) follow-up, all the onlays were found to be in place with complete elimination of pre-treatment sensitivity. Marginal integrity and anatomic form remained unaltered over time. Depreciation in colour stability and evidence of cavosurface marginal discolouration at 30 months was evident in only one of the restored onlays. Thus, Indirect Resin onlays may serve as esthetic conservative restorative alternative for MIH affected molars with favourable outcomes.
