Aim and objectives The aim of this in-vitro study is to evaluate and compare the effect of various mouth rinsing agents on frictional resistance through sliding mechanics among orthodontic metal brackets and stainless steel (SS) archwire. Materials and methods Each group comprised 15 samples of maxillary first premolar pre-adjusted edgewise SS movable, un-bonded brackets (Koden Inc., United States) which were welded with a power arm, where 100 g of the load was suspended. Brackets were ligated with elastic modules (Koden Inc., United States) onto the perspex sheet along with 0.019" x 0.025" SS archwire (Classic Orthodontics, United States) and were suspended from the upper component of the Instron machine. The coefficient of friction was tested in dry conditions (control), artificial saliva (AS) (Wet Mouth, ICPA Health Product Ltd., India), 0.2% chlorhexidine gluconate (CHG) mouthwash (Hexidine, ICPA Health Product Ltd., India), 0.05% sodium fluoride (NaF) mouthwash (ACT Anti-Cavity Fluoride Mouthwash, Sanofi Company, United States), charcoal (CC) mouthwash (Hello Activated Charcoal Extra Freshening Mouthwash, Hello Products LLC, United States) and ozone-infused oil-pulling solution with coconut oil (O) (O Essentials, Health Ranger Store, United States). In order to calculate the coefficient of friction, 50 L was addedto the test sample while moving at a 5 mm/min crosshead speed. The groups were compared using the one-way analysis of variance (ANOVA), and Tukey's post hoc analysis was performed for multiple pairwise comparisons. Results The coefficient of friction with the highest mean values was observed with the control group (2.01), followed by AS (1.79), and the least with O (1.15). Statistically significant differences were observed with almost all groups of mouth rinsing agents, but NaF is significant with CHG and CC. However, CHG did not have any significant difference from CC. Conclusions Lower coefficient of frictional values were observed with the ozone-infused oil-pulling solution with coconut oil during sliding mechanics between metal brackets and stainless steel archwire. Almost all the mouth rinsing agents showed a significantly different coefficient of friction value.
目的和目标 本体外研究的目的是评估和比较各种漱口剂对正畸金属托槽与不锈钢（SS）弓丝之间滑动力学摩擦阻力的影响。材料和方法 每组包括15个上颌第一前磨牙预调整直丝SS活动、未粘结托槽样本（美国Koden公司），这些托槽与一个动力臂焊接，在动力臂上悬挂100 g的负载。托槽用弹性模块（美国Koden公司）与0.019"×0.025" SS弓丝（美国Classic Orthodontics公司）一起结扎在有机玻璃板上，并从Instron机器的上部组件悬挂下来。在干燥条件（对照组）、人工唾液（AS）（印度ICPA健康产品有限公司的Wet Mouth）、0.2%葡萄糖酸氯己定（CHG）漱口水（印度ICPA健康产品有限公司的Hexidine）、0.05%氟化钠（NaF）漱口水（美国赛诺菲公司的ACT防蛀氟化物漱口水）、炭（CC）漱口水（美国Hello Products LLC公司的Hello活性炭超强清新漱口水）和含臭氧的椰子油拉油溶液（O）（美国Health Ranger Store公司的O Essentials）中测试摩擦系数。为了计算摩擦系数，在以5 mm/分钟的十字头速度移动时向测试样本中添加50 L。使用单因素方差分析（ANOVA）对各组进行比较，并进行Tukey事后分析以进行多个成对比较。结果 对照组的摩擦系数平均值最高（2.01），其次是AS（1.79），O组最低（1.15）。几乎所有漱口水组之间均观察到统计学上的显著差异，但NaF与CHG和CC有显著差异。然而，CHG与CC没有任何显著差异。结论 在金属托槽与不锈钢弓丝之间的滑动力学过程中，含臭氧的椰子油拉油溶液的摩擦系数值较低。几乎所有漱口水的摩擦系数值均有显著差异。
