Chlorine dioxide-containing mouthwash may not impact frictional resistance or surface roughness of Orthodontic Archwire: Study
Chlorine dioxide-containing mouthwash may not impact frictional resistance or surface roughness of Orthodontic Archwire suggests a study published in the F1000Research.
They involve various types of mouthwashes which have been reported to cause alteration of mechanical properties of archwires. This study aimed to evaluate the effects of a new kind of chlorine-dioxide-containing mouthwash on the mechanical properties and surface morphology of stainless steel orthodontic archwires against the already prevalent chlorhexidine mouthwash in the market.
Group A - Chlorhexidine mouthwash 0.2% (study), Group B - Chlorine Dioxide mouthwash (study), and Group C - Artificial Saliva (control). 42 specimens of 5 cm long 19x25 inch SS archwires were immersed in each group equally. Post immersion, the frictional force was analyzed in the universal testing machine for each group using custom-made acrylic jigs for 10 specimens. The remaining 4 specimens from each group were sent for surface morphology evaluation using an atomic force microscope. Results: Friction resistance evaluation for the archwires revealed a mean friction of 0.011 ± 0.0056 in Group A, 0.015 ± 0.0052 in Group B, and 0.010 ± 0.0067 in Group C.
esults suggested that the static friction of Group C (control group) was found to be the least when compared with the experimental groups, although not producing statistically significant values. Surface roughness of archwires compared at a 10μm range revealed a mean roughness of 19.38 ± 0.82 in Group A, 25.39 ± 7.01 in Group B, and 16.65 ± 3.07 in Group C which shows there wasn't any statistically significant difference in the mean roughness midst the three sets. Researchers concluded that Chlorine dioxide-containing mouthwash does not significantly impact the frictional resistance or surface roughness of stainless steel orthodontic archwires under the tested conditions.
Chlorine dioxide may serve as a potential adjunct in orthodontic treatment. However, further research, particularly in vivo studies, is required to validate these findings and assess its long-term effects on orthodontic materials. Therefore Understanding the effects of Chlorine dioxide mouthwash on stainless steel archwires can aid in developing a mechanically efficient archwire-mouthwash combination for orthodontic treatment. Additionally, this study provides a foundation for future comparisons between Chlorine dioxide and the gold-standard Chlorhexidine mouthwash.
