White spot lesions are sub-surface demineralized enamel caused by a variety of factors including plaque accumulation, post-orthodontic treatment, fluorosis, and hypomineralization. These white opacities when present in the smile line can pose an esthetic concern for many patients. Icon resin infiltration is a modern, minimally invasive technique aimed to diminish the appearance of white spot lesions and treat initial caries.
Methods43 year-old female patient presents to Penn Dental Medicine with an asymmetrical white spot lesion on the mid-incisal third of #8 facial surface. Lesion treated with Icon following manufacture instructions: etch with 15% hydrochloric acid gel, dry with ethanol, infiltrate with provided resin. Photographic records taken immediately after treatment and at 3 week follow-up.
ResultsThe white spot lesion showed significant reduction in appearance after treatment with Icon. However, the spot was not entirely masked and the border of the original lesion can still be seen.
ConclusionIcon can be an effective treatment option for patients with white spot lesions. However, it is limited to shallow areas of demineralization to allow for full penetration of the resin infiltrant. Thus, adequate case selection is necessary for success. Clinical Significance: Icon provides a conservative alternative to treating white spot lesions in the esthetic zone. Resin infiltration allows for immediate results with reduced chairside time and less patient discomfort compared to traditional techniques.
