The purpose of this clinical report was to describe the detection of fluorescent resin residue after orthodontic bracket debonding with two UV light devices and analyze the surface morphology of enamel after 1 year.
A 22-year-old woman had orthodontic brackets removed by a previous dentist; however, resin residue was left on the enamel of the maxillary teeth. After confirming the fluorescent property of the resin, different protocols were used for each half of the maxillary arch. The first method, a black light lens was attached to a light-curing device to detect resin fluorescence, followed by polishing with silicone rubber tips. The second method used a light emitting diode light system attached to and activated by a high-speed handpiece, followed by polishing with discs. Both methods were completed with diamond polishing paste applied with felt discs. Polyvinyl siloxane impressions were made initially, after residue removal, after finishing and after polishing for morphologic analysis. The results were evaluated with photographs and the scanning electron microscope images made of resin casts from the impressions. A follow-up was made after 1 year.
Both methods yielded a satisfactory clinical outcome, with a smooth surface, acceptable surface gloss and minimal tooth wear. The use of a UV device that excites fluorescence is recommended for the controlled removal of resin residue on enamel.
The controlled removal of resin residue from enamel after orthodontic treatment is challenging but can be improved with auxiliary methods for detecting resin residues. This clinical report describes two types of devices that excite fluorescent resins in a more rapid and precise technique to guide the practitioner in the controlled removal of residual resin on teeth.
本临床报告旨在描述使用两种紫外光设备检测正畸托槽拆除后残留的荧光树脂，并分析 1 年后牙釉质的表面形态。
一名 22 岁女性曾由前一位牙医进行正畸托槽拆除，但牙釉质上仍残留树脂。在确认树脂具有荧光特性后，对上颌牙弓的每一半使用不同的方案。第一种方法是将黑光镜片附着在光固化设备上以检测树脂荧光，然后用硅橡胶尖端进行抛光。第二种方法是将发光二极管光系统附着并通过高速手机激活，然后用 discs 进行抛光。两种方法都使用带有 felt discs 的金刚石抛光膏完成。最初进行聚硅氧烷印模，然后在去除残留、完成和抛光后进行形态分析。使用从印模制作的树脂铸型的照片和扫描电子显微镜图像进行结果评估。1 年后进行随访。
两种方法均取得了满意的临床效果，表面光滑，表面光泽度可接受，牙齿磨损最小。建议使用激发荧光的紫外光设备来控制去除牙釉质上的树脂残留。
正畸治疗后从牙釉质上去除树脂残留具有挑战性，但可以通过辅助检测树脂残留的方法来改善。本临床报告描述了两种类型的设备，它们以更快速和精确的技术激发荧光树脂，以指导医生在受控的情况下去除牙齿上的残留树脂。
