Abstract
Aims: The current study aimed to discover if the use of magnetized water (MW) as a mouthrinse will affect the release of Chromum (Cr) ion from stainless steel (SS) orthodontic archwires. In addition to study surface topography of SS orthodontic archwires after and before immersion in MW by atomic force microscope (AFM). Materials and Methods: 80 (0.016” X0.022”) as received orthodontic SS archwires from the manufacturer company (Dentarum, Germany). The archwires were divided into four main groups according to the mouthrinse used as follows: magnetized water prepared at high power magnetic field group (MWH), magnetized water prepared at low power magnetic field group (MWL), Ortho Kin group (control positive) (OK) and distilled water group (control negative) (DW). Each group contain four times point intervals (24hr (hour), 1w (week), 3w and 4w). For each time interval, five archwires were used. The Cr ion release was measured at different time intervals (24hr, 1w, 3w and 4w) by using atomic absorption spectrometer (AAS) (BUCK Scientific, USA). And the surface topography of SS orthodontic archwires was measured by atomic force microscope (AFM) (NaioAFM Nanosurf, Switzerland). Statistical analysis was done using V26. SPSS Statistics, Data were analyzed with one-way ANOVA and Duncan’s multiple range tests. Results: MWH and MWL groups had significantly less amounts of Cr ions release from SS orthodontic archwires when compared with OK mouthrinse group. Conclusions: MW can be used as a safer alternative to other commercially current mouthrinses (as OK) for orthodontic patients.
