Resin Infiltration Treatment for MIH

The investigators aimed to evaluate changes in mineralisation degree, colour, and size of the lesion after Icon® in permanent teeth with MIH in 6 months.

A total of 116 permanent central teeth of 37 patients were included in the study. Icon® was applied to teeth with MIH, while the healthy teeth received no treatment (control). Group I : Icon® resin infiltration treatment was performed on 58 permanent central teeth with MIH and evaluated before; immediately after; and 1, 3, and 6 months after the procedure. Group II (Control Group): No treatment was performed on healthy teeth. However, similar to the treated teeth, 58 healthy permanent central teeth of the same individuals were evaluated before; immediately after; and 1, 3, and 6 months after the procedure. Lesions were evaluated before, immediately after, and 1, 3, and 6 months after treatment. Mineralisation degree of MIH lesions was evaluated using DIAGNOdent Pen, changes in the lesion colour and lesion size were evaluated using VITA EasyShade and the cross polarization technique, respectively.

A sufficient amount of HCl was applied to the lesion using the icon etch syringe included in the set and was allowed to sit for 2 minutes. After washing with water for 30 seconds, the tooth was dried using an air spray. Once the enamel surface appeared chalky, Icon® dry application was initiated. Ethanol was applied to the lesion using the Icon® dry syringe included in the set, and after 30 seconds it was dried using an air spray. Sufficient amount of resin infiltrant was applied to the lesion using the Icon® infiltrant syringe. The resin infiltrant was applied to the lesion surface by massaging with the tip of the syringe in circular movements for 3 minutes such that it penetrates the surface thoroughly. The resin infiltrant was polymerized for 40 seconds with a light device.

Changes in the MIH lesions colour was evaluated using VITA EasyShade (Spectrophotometers are equipped with sensors that can measure in many wavelengths)
