Abstract |
The prevalence of developmental defects of enamel and lesios by post-orthodontic decalcification has been reported with increasing frequency. Even though there have been increasing interests and clinical challenges in esthetic improvement of these lesions, few of studies were reported for using non-invasive approach which is a very significant matter for child and young adults. This study was conducted to assess clinical effect on the improvement in color of these lesions via resin infiltration method developed as minimum invasive technique for white spot. For the 38 maxillary anterior teeth with calcification problem, the changes in color between before- and after- infiltration treatment, were evaluated and summarized as following. 1. A week after infiltration, 25% of developmental defects and 61% of decalcification lesions were improved in color as the value of ΔE below 3.7. 2. 40% of the developmental defects and 6% of decalcification lesions showed no significant change. 3. The developmental defects showed more remarkable changes in color 1 week after infiltration rather than immediately after the treatment. From our study results, it is considered that the amount of color improvement depended on the depth of lesion. In other words, for the lesion having more depth than the depth infiltrant resin can penetrate into, infiltration treatment showed no significant effect. Therefore, for clinical indication of resin infiltration treatment, further research on precise measurement technique of lesion depth is strongly required. |
