INFILTRATION
The use of infiltrants for masking enamel discolourations in hypomineralized teeth has spread more recently [The primary mechanism of DIAGNOdent is based on different absorption and scattering of laser fluorescence radiation of the carious lesion compared to the surrounding healthy tissue [Histological studies have shown an increase in microporosity within the different layers of hypomineralised enamel lesions [Nowadays, many colour systems are used in restorative and prosthetic dental treatments; the most preferred system in recent years is the CIELAB (ΔEab) colour system [In this study, we found that the ΔE values calculated immediately after resin infiltration treatment and those calculated 1, 3, and 6 months later were, on average, greater by a factor of ΔE 3.7 compared to the initial values. Moreover, the colour change was clinically perceptible after resin infiltration treatment, as reported in the literature. However, the colour change was less in the control group compared to that in the treatment group at all times [The length of etching and drying application time affects the homogeneity and depth of the resin infiltration. C. Kobbe, et al.[In their study, Khanna et al.[Similar to the aforementioned studies, we observed a significant decrease in the lesion areas after resin infiltration treatment (Icon®), which remained stable for 6 months. Since measuring the lesion areas using Image J is an advanced and repeatable method, and millimetric measurements obtain accurate results, it may be preferred over measurements performed using a periodontal probe or the naked eye in the clinic. We consider that using cross-polarisation photography provides more accurate information about the severity of MIH compared to visual examination or regular photo shoots. Studies on this subject are rare, which warrants more studies to support this information.
