Abstract
Aims: The current study aimed to explore if the use of magnetically treated water (MTW) as a mouthrinse will affect the release of nickel (Ni) ion from stainless steel (SS) orthodontic archwires. In addition to study the surface characteristic of SS archwire after using MTW by scanning electron microscope (SEM). Materials and Methods: forty-five (0.016” x 0.022”) as received new orthodontic SS archwires from the company (Dentarum, Germany). The archwires divided into three main groups depending on the mouthrinse used as follows: magnetically treated water group (MTW), distilled water group (control negative) (DW) and Ortho Kin group (control positive) (OK). Each group contains three times point intervals (24hours, 2 weeks, and 4 weeks). Five archwires were used in each interval. The Ni ion release was measured at different time intervals (24hours, 2 weeks and 4 weeks) by using atomic absorption spectrometer (BUCK Scientific, USA). And surface characteristics were determined by using scanning electron microscope (SEM) (TESCAN MIRA3, French). Statistical analysis was done using SPSS Statistics, V26. Data were analyzed with one-way ANOVA and Duncan’s multiple range tests. Results: MTW group caused significantly less amounts of Ni ions release from SS orthodontic archwires when compared with OK mouthrinse group. Conclusions: MTW can be used as a safer adjunct or alternative to other commercially available chemical mouthrinses (as OK) during orthodontic treatment course.
