CLINICAL CHARACTERISTICS OF MOLAR-INCISOR HYPOMINERALISATION (MIH) IN PERMANENT TEETH OF 6-7-YEAR-OLD CHILDREN BEFORE AND IMMEDIATELY AFTER TREATMENT WITH RESIN INFILTRATION
Main Article Content
Abstract
Objective: Clinical description of the characteristics before and immediately after treatment of molar-Incisor hypomineralization (MIH) in 6-7-year-old children using ICON-DMG resin infiltration technique in Hanoi. Subject and methods: This descriptive study evaluated 36 MIH-affected teeth with white-cream or yellow-brown opacities in 21 children aged 6-7 years, treated with ICON-DMG resin infiltration. Clinical characteristics were assessed before and immediately after treatment. Results: The average number of ICON Etch applications was 5,28±1,74; the average number of resin infiltration applications was 1,46±0,37; and the average number of composite restorations was 0,90±0,77. Before treatment, 80,55% of teeth showed no sensitivity, increasing to 94,44% after treatment. Sensitivity to stimuli without requiring treatment interruption was recorded in 11,11% of teeth before treatment and decreased to 2,78% after treatment. The mean score assessing the difference between the lesion area and the sound enamel area during direct clinical examination was 1,31±0,61 points before treatment, reducing to 0,54±0,42 points immediately after treatment. When assessed under EP light, the mean score for the difference between the lesion area and the sound enamel area was 1,74±0,41 points before treatment, decreasing to 0,33±0,30 points immediately after treatment. Conclusions: The treatment of MIH-affected permanent teeth with white-opaque or yellow-brown opacities in 6-7-year-old children using the resin infiltration technique (ICON-DMG) demonstrated clear clinical effectiveness. The treatment resulted in reduced tooth sensitivity and improved aesthetics, with the lesion margins becoming blurred and hardly detectable immediately after treatment. The use of EP light contributed to enhancing diagnostic accuracy and improving the ability to observe and compare the lesion areas during diagnosis and follow-up.
