Change in Oral Health-Related Quality of Life Following Minimally Invasive Aesthetic Treatment for Children with Molar Incisor Hypomineralisation: A Prospective Study.

Molar incisor hypomineralisation (MIH) is a common enamel condition, presenting with incisor opacities, which may be of psychosocial concern to children. This clinical study sought to determine whether minimally invasive treatment, aiming to improve incisor aesthetics, would also improve children's oral health-related quality of life (OHRQoL). 111 MIH patients, aged 7⁻16 years, referred to a UK Dental Hospital, were invited to complete the Child Oral Health Impact Profile (C-OHIP-SF19) prior to any intervention (T₀) and again at one-month following the intervention (T₁) for MIH. Treatment regimens included one or more of the following: Microabrasion; resin infiltration; tooth whitening; resin composite restoration. Data were obtained for 93 children with a mean age of 11 years. Mean total C-OHIP-SF19 score at T₀ was 47.00 (SD = 9.29; range = 0⁻76) and this increased significantly at T₁ to 58.24 (SD = 9.42; range = 0⁻76; < 0.001, paired -test), indicating a marked improvement in self-reported OHRQoL. There were no statistically significant differences according to gender. This is the first study to show that simple, minimally invasive dental treatment, to reduce the visibility of enamel opacities, in MIH, can have a positive impact on children's wellbeing.
