| Summary: | Introduction: The use of mobile phones has considerably
increased, and the Electromagnetic Radiation (EMR) caused
by these devices may influence intraoral appliances. Intraoral
elastics are commonly employed in orthodontics and require
periodic changing by the patient to be effective. Unfortunately,
changes in mechanical properties are one of the biggest
drawbacks of using elastics.
Aim: To evaluate the effects of Radiofrequency Electromagnetic
Radiation (RF-EMR) on the mechanical properties of intraoral
orthodontic elastics under in-vitro conditions.
Materials and Methods: This in-vitro study was conducted in
the Department of Orthodontics at Saveetha Dental College,
Chennai, Tamil Nadu, India, from February 2022 to June 2022. A
total of 300 elastics with different diameters and force-exerting
abilities were selected and divided into five categories (n=60).
The five elastic groups were yellow, blue, green, red, and pink.
These elastics were then exposed to EMR emitted from a cellular
device for 1.5 hours per day over two days. The mechanical
properties of the elastics were tested before and after exposure
to EMR. Analysis of variance was used to determine if a
significant difference existed between the groups, and Tukey’s
post-hoc test was used to determine significant differences in
the mean (p-value <0.05). The analysis was performed using
Statistical Package for the Social Sciences (SPSS) version 23.0
(SPSS Inc., Chicago, IL, USA).
Results: The results of the present study showed a statistically
significant difference in rupture strength (p<0.001) and force
decay (p<0.001) of the intraoral elastics before and after
exposure to EMR. However, there was no change in the thickness
and optical properties of all the elastics after exposure. The
average remaining force of the intraoral elastics after exposure
to EMR emitted from a cell phone device was 41.1% after force
decay, and red elastics were the least colour stable, while green
elastics were the most colour stable.
Conclusion: EMR emitted from mobile phones and other devices
can influence the mechanical properties of intraoral elastics in
terms of rupture strength, force decay, and colour stability |
