摘要
目的探究清肺排毒汤(QFPDD)对不同托槽系统摩擦力的影响,以期为使用QFPDD治疗感染新型冠状病毒的正畸患者提供诊疗参考。方法选取前磨牙主动自锁托槽(GAC In-Ovation)、被动自锁托槽(Damon Q)及传统结扎托槽(新亚标准型网底直丝弓托槽)共54颗,分别与不同尺寸的3M不锈钢丝[0.018 inch(1 inch=2.58 cm)圆丝,0.018 inch×0.025 inch、0.019 inch×0.025 inch方丝]组成摩擦力学系统。托槽系统分别浸泡于QFPDD及人工唾液中,而后转移至万能力学试验机进行摩擦力的测量。在扫描电镜下观察不同介质浸泡后不锈钢丝的表征,明确QFPDD与人工唾液浸泡后弓丝表面碎屑的堆积程度。采用双因素方差分析进行统计分析。结果GAC In-Ovation、Damon Q与0.018 inch不锈钢圆丝组成的托槽系统在2种不同介质浸泡下的摩擦力比较,差异均无统计学意义(P>0.05),而2种自锁托槽与0.018 inch×0.025 inch、0.019 inch×0.025 inch不锈钢方丝自结扎后在QFPDD浸泡下的摩擦力增大,差异有统计学意义(P<0.001)。新亚标准型网底直丝弓托槽与3种尺寸弓丝结扎后在QFPDD浸泡下的摩擦力增大,差异有统计学意义(P<0.01)。此外,在2种介质下,传统结扎托槽的摩擦力均明显高于自锁托槽,差异有统计学意义(P<0.001);GAC In-Ovation相较于Damon Q在2种尺寸的不锈钢方丝状态下的摩擦力更大。经过QFPDD浸泡后的弓丝,在扫描电子电镜下可观察到其表面存在大量的碎屑黏附。结论QFPDD介质下的托槽系统摩擦力增强,汤剂中的悬浮物将恶化弓丝表面的碎屑堆积。服用QFPDD等中药汤剂的正畸患者可能需要相对特殊的口腔护理措施。
Objective To explore the effect of Qing-Fei-Pai-Du decoction(QFPDD)on the friction of different bracket systems,in order to provide a reference for the treatment of orthodontic patients infected with Corona Virus Disease 2019(COVID-19)using QFPDD.Methods A total of 54 premolar active self-ligating brackets(GAC In-ovation),passive self-ligating brackets(Damon Q)and traditional ligating brackets(Shinye standard mesh straight wire arch brackets)were selected and compared with 3M stainless steel wires[0.018 inch(1 inch=2.58 cm)round wire;0.018 inch×0.025 inch and 0.019 inch×0.025 inch square wire]with different sizes to form a friction mechanics system.The bracket systems were immersed in QFPDD and artificial saliva respectively,and then transferred to the universal mechanical testing machine for friction measurement.The characterization of stainless steel wire after soaking in different media was observed under scanning electron microscope,and the accumulation degree of debris on the surface of arch wire after soaking in QFPDD and artificial saliva was clarified.A two-way ANOVA analysis of variance was used for statistical analysis.Results There was no significant difference in the friction force of the bracket system composed of GAC In-Ovation,Damon Q and 0.018 inch stainless steel round wire under two different media immersion(P>0.05),while the friction of two self-ligating brackets increases under the medium of traditional Chinese medicine with 0.018 inch×0.025 inch and 0.019 inch×0.025 inch steel square wire(P<0.001).The friction force of the new sub-standard straight wire arch bracket under QFPDD medium immersion increased after ligation with three kinds of arch wires,and the difference was statistically significant(P<0.01).In addition,the friction force of traditional ligation brackets was significantly higher than that of self-locking brackets in both media(P<0.001).The friction force of GAC In-Ovation was greater than that of Damon Q in the two stainless steel square wire states.After immersion in QFPDD,
