Resin Infiltration Treatment for MIH

Clinical Evaluation of the Effect of Resin Infiltration Treatment on Hypomineralised Enamel Surfaces

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.

Inclusion Criteria:

• Molar incisor hypomineralisation on the labial surface of permanent central teeth Least one of the labial surface of the permanent anterior teeth were affected by MIH.

Exclusion Criteria:

• Dental caries and filling on anterior teeth.
• Dental anomaly on anterior teeth.
• Undergoing orthodontic treatment.
• Periodontal diseases.
• Cognitive and behavioural problems.
