Invisalign has improved periodontal health in comparison to traditional metal wire braces. Due to a growing interest in attaining better teeth esthetics, there are more adults seeking Invisalign treatment. Ten percent carbamide peroxide (CP) breaks down to 6.5% urea and 3.5% hydrogen peroxide, which elevates oral pH, removes stains, and diminishes caries by inhibiting plaque formation. The aim of this study is to investigate whether 10% CP use during Invisalign treatment can enhance tooth shade esthetics while decreasing plaque levels and improving gingival health indices. Twenty-eight patients at Western University dental center undergoing Invisalign were assigned to two groups where the experimental group applied daily bleaching material (10% CP, Ultradent Inc., South Jordan, UT, USA), while the control group did not for 4 weeks. Tooth shade, plaque index (PI), and gingival index (GI) were assessed at baseline and in 2-week intervals for 6 weeks. Results showed that 10% CP had significant change in tooth shade over the 2- and 4-weeks periods ( < 0.05) and significantly reduced plaque and gingival indices ( < 0.05), with minimal to no relapse after 2 weeks post-op. Thus, applying CP at 10% may be a useful application during Invisalign treatment in improving teeth shade and overall gingival health.
与传统金属丝牙套相比，隐适美改善了牙周健康状况。由于人们对获得更美观牙齿的兴趣日益浓厚，越来越多的成年人寻求隐适美治疗。10%的过氧化脲（CP）分解为6.5%的尿素和3.5%的过氧化氢，可提高口腔pH值、去除污渍并通过抑制牙菌斑形成减少龋齿。本研究的目的是调查在隐适美治疗期间使用10%的CP是否能在降低牙菌斑水平和改善牙龈健康指数的同时提高牙齿色泽美观度。西部大学牙科中心的28名接受隐适美治疗的患者被分为两组，实验组每天使用漂白材料（10%的CP，美国犹他州南乔丹市Ultradent公司），而对照组4周内不使用。在基线时以及6周内每2周评估一次牙齿色泽、菌斑指数（PI）和牙龈指数（GI）。结果显示，10%的CP在2周和4周期间牙齿色泽有显著变化（<0.05），并显著降低了菌斑和牙龈指数（<0.05），术后2周后复发极少或无复发。因此，在隐适美治疗期间应用10%的CP可能有助于改善牙齿色泽和整体牙龈健康。
