Herbs are used widely in medicine. The purpose of the present study was to assess the ion release from gold-plated orthodontic bracket compared with other stainless steel brackets, and based on the findings of the study, the orthodontists can choose the most biocompatible brackets and mouthwashes useful in the clinical practice.
A total of 150 orthodontic brackets from Orthotechnology™ Company, USA (50 stainless steel one-piece brackets, 50 stainless steel two-piece brackets, and 50 gold brackets) were immersed in four mouthwashes in addition to distilled water. Ten of each type of brackets in every media were immersed under 37°C for 45 days. Ions released in these mouthwashes were measured, and comparisons among different bracket types and among various mouthwashes were done by one-way analysis of variance (ANOVA) and then with Games-Howell tests.
Increased amounts of ions released in herbal mouth-washes were recorded in gold and two-piece brackets in comparison with one-piece stainless steel brackets.
Herbal mouthwashes must be used with caution as they showed an increased amount of ions released in comparison with chlorhexidine. One-piece stainless steel bracket system is the most compatible bracket type, as they released the least amount of ions.
One-piece stainless steel brackets are better than two-piece brackets in terms of ions released.
草药在医学中被广泛使用。本研究的目的是评估镀金正畸托槽与其他不锈钢托槽相比的离子释放情况，并根据研究结果，正畸医生可以选择在临床实践中最具生物相容性的托槽和漱口水。
共有150个来自美国Orthotechnology™公司的正畸托槽（50个不锈钢一体式托槽、50个不锈钢分体式托槽和50个金色托槽）除了浸泡在蒸馏水中外，还浸泡在四种漱口水之中。每种类型的托槽在每种介质中各取10个，于37°C下浸泡45天。测量这些漱口中释放的离子，并通过单因素方差分析（ANOVA）以及随后的Games-Howell检验对不同类型的托槽和各种漱口水之间进行比较。
与不锈钢一体式托槽相比，金色托槽和分体式托槽在草药漱口中释放的离子量增加。
与氯己定相比，草药漱口水显示出释放的离子量增加，因此必须谨慎使用。不锈钢一体式托槽系统是最具相容性的托槽类型，因为它们释放的离子量最少。
在离子释放方面，不锈钢一体式托槽比分体式托槽更好。
