Making white spots disappear! Do minimally invasive treatments improve incisor opacities in children with molar‐incisor hypomineralisation?

Description
Summary:Background Children with molar‐incisor hypomineralisation (MIH) frequently seek aesthetic treatment for incisor opacities. Surprisingly, few studies have evaluated the clinical success of such interventions. Aim To quantify the effectiveness of minimally invasive treatments in reducing enamel opacity visibility in children with MIH. Design This in vitro study used digital clinical images of 23 children aged 8–16 years with MIH who underwent microabrasion and/or resin infiltration for the management of incisor opacities. Standard images were taken pre‐treatment and 6 months post‐treatment. Image software (Image‐Pro Plus®V7) was employed to convert 24‐bit RGB images to 16‐bit greyscale and 145× magnification. Measurement repeatability was assessed using intra‐class correlation coefficients (ICCs). Post‐treatment changes in visible opacity area (mm2) and brightness (greyscale value) were tested using the Wilcoxon signed‐rank test for related samples. Results The mean total opacity surface area significantly reduced from 14.3 mm2 (SD = 7.5) to 9.4 mm2 (SD = 9.0) post‐treatment. The proportion of tooth surface affected by the opacity also significantly reduced from 22.5% (SD = 10.5) to 14.7% (SD = 12.7). The mean maximum opacity brightness significantly reduced from 53 066 greyscale value (SD = 4740) to 49 040 (SD = 3796). ICC was good/excellent (0.75–1.0). Conclusion Minimally invasive treatment is effective in reducing the size and brightness of discrete incisor opacities. Future research should compare objective findings with patient‐reported outcomes.
