Recently, dental bleaching has been frequently sought by patients to improve the appearance and color of the teeth. Among various treatment options, in-office bleaching is commonly preferred by patients with severely discolored teeth due to its fast aesthetic results. In addition, other pretreatment methods, such as air-powder polishing, have been reported to increase the efficacy of bleaching treatment. Compared to other causes of tooth discoloration, occupational tooth discoloration caused by bronze alloy and further treatment have not been sufficiently documented in the literature. In the present case report, we explain a case of tooth discoloration following exposure to a bronze alloy and a conservative clinical approach used for the management of tooth discoloration. A 15-year-old male patient who worked in a foundry was presented with tooth discoloration. At the first session, a rubber-cap prophylaxis was performed. After one week, air-powder polishing was used to remove the remaining stains. Finally, at the third session, two cycles of bleaching were performed using hydrogen peroxide gel 35%, each for 20 minutes. Photographs were taken at the end of each session and used for visual evaluation. The final result was aesthetically satisfactory.
最近，患者经常寻求牙齿美白来改善牙齿外观和颜色。在各种治疗选择中，由于诊室美白具有快速的美学效果，牙齿严重变色的患者通常更喜欢这种方法。此外，据报道，其他预处理方法，如喷粉洁牙，可提高美白治疗的效果。与其他牙齿变色原因相比，由青铜合金引起的职业性牙齿变色及进一步治疗在文献中尚无充分记载。在本病例报告中，我们阐述了一例接触青铜合金后牙齿变色的病例以及用于处理牙齿变色的保守临床方法。一名在铸造厂工作的15岁男性患者出现牙齿变色。在第一次就诊时，进行了橡皮障预防性治疗。一周后，使用喷粉洁牙去除残留污渍。最后，在第三次就诊时，使用35%的过氧化氢凝胶进行了两个周期的美白治疗，每次20分钟。每次就诊结束时拍摄照片用于视觉评估。最终结果在美学上令人满意。
