Transillumination‐Aided Infiltration of MIH‐Affected Molars: Evaluation of the Clinical Workflow
International Journal of Paediatric Dentistry, EarlyView.ABSTRACT Background Enamel affected by molar incisor hypomineralisation (MIH) exhibits reduced mechanical properties due to its disorganised prismatic structure, lower mineral density and higher protein content. These alterations increase porosity and susceptibility to posteruptive enamel breakdown.
