To evaluate the effect of impregnating an orthodontic resin composite with probiotic bacteria ( GG) on the levels of () in patients undergoing orthodontic treatment. Thirty patients were randomly selected and allotted by block randomization to two groups: an experimental group, who received brackets bonded with probiotic impregnated resin composite and a control group, who received brackets bonded with conventional light cure resin composite. Plaque samples were collected before (ET0 and CT0) and two months (ET1 and CT1) after bonding. Levels of were assessed using the colony count method. Two months after bonding of the brackets, the levels had decreased with statistical significance in the experimental group ( = 0.001), but not in the control group ( = 0.137). Impregnation of resin composite with probiotic bacteria for the purpose of preventing formation of white spot lesions on enamel holds promise. Long-term evaluation would be necessary to provide confirmatory results.
为评估用益生菌（GG）浸渍正畸树脂复合材料对正畸治疗患者口腔内（此处原文括号内容缺失，无法准确翻译）水平的影响。随机选取30例患者，通过区组随机化分为两组：实验组，接受用含益生菌浸渍树脂复合材料粘结的托槽；对照组，接受用传统光固化树脂复合材料粘结的托槽。在粘结前（ET0和CT0）和粘结后两个月（ET1和CT1）收集菌斑样本。使用菌落计数法评估（此处原文括号内容缺失，无法准确翻译）水平。粘结托槽两个月后，实验组（此处原文括号内容缺失，无法准确翻译）水平有统计学意义的下降（P = 0.001），而对照组无下降（P = 0.137）。用益生菌浸渍树脂复合材料以预防牙釉质上白斑病变的形成具有前景。需要进行长期评估以提供确证性结果。
