Cell phone radiation effects on cytogenetic abnormalities of oral mucosal cells

Abstract

The aim of this study was to evaluate the effects of exposure to cell phone electromagnetic radiation on the frequency of micronuclei, broken eggs cells, binucleated cells, and karyorrhexis in epithelial cells of the oral mucosa. The sample was composed of 60 cell phone users, who were non-smokers and non-drinkers, and had no clinically visible oral lesions. Cells were obtained from anatomical sites with the highest incidence of oral cancer: lower lip, border of the tongue, and floor of the mouth. The Feulgen reaction was used for quantification of nuclear anomalies in 1,000 cells/slide. A slightly increase in the number of micronucleated cells in the lower lip and in binucleated cells on the floor of the mouth was observed in individuals who used their phones > 60 minutes/week. The analysis also revealed an increased number of broken eggs in the tongue of individuals owning a cell phone for over eight years. Results suggest that exposure to electromagnetic waves emitted by cell phones can increase nuclear abnormalities in individuals who use a cell phone for more than 60 minutes per week and for over eight years. Based on the present findings, we suggest that exposure to electromagnetic radiation emitted by cell phones may interfere with the development of metanuclear anomalies. Therefore, it is demonstrated that, despite a significant increase in these anomalies, the radiation emitted by cell phones among frequent users is within acceptable physiological limits.

Effect of Cell Phone Radiations on Orofacial Structures: A Systematic Review

“…The lower lip had a higher amount of binucleated cells and broken eggs (structures associated with gene amplification). Reason for this may be, these sites are near to the cell phone, a source of electromagnetic radiation and also exposed to solar radiations [18]. Similar results were obtained by Souza Lda C et al, [39].…”

Effects of mobile phone radiation on buccal mucosal cells based on specific absorption rate: a cross sectional study

“…Exposed individuals included both males and females who use smart phone. Sample size calculation was performed according to study conducted by Daroit et al 1 Considering a study with an 80% power and α=0.05, the minimum sample size was arrived as 54 individuals using G-POWER software version 3.1.…”

“…The rapid increase in the use of mobile phone has raised the health concerns about potential risks associated with exposure to electromagnetic fields produced by the mobile phone radiation. 1 In India, according to Telecom regulatory authority of India, New Delhi, September 2019, total wireless Telephone Subscribers were 1168.31 Million with an increasing monthly growth rate of 0.24%. 2 As of present scenario, mobile phones are used at an enormous number by all the age-groups, particularly highest in the age group of 25-34 years.…”

“…Few authors like Daroit et al, Banerjee et al, have confirmed the genotoxicity of mobile radiation on oral mucosa, while authors like Ros-Llor et al, Hintzsche et al had apparently denied the genotoxic effect of mobile phone radiations. 1,7,11,12 Considering all these mixed views, re-evaluation of the effect of mobile radiation on the oral epithelium is warranted. Hence this study was designed to evaluate the MN frequency in exfoliated oral mucosal cells in high and low mobile users based on SAR value.…”

The Determination of Health Services Vocational School Students’ Knowledge Levels About the Effects of Radiation on Health

“…Sun rays, radio waves that enable radio and television communication, radiofrequency waves emitted from mobile phones, waves emitted by devices used for diagnosis and treatment in health field, x-rays used in industry constitute part of the radiation sources which effect our daily lives (Bauer, Janßen, Schmitz, & Ott, 2017;Bijwaard et al, 2017;Daroit, Visioli, Magnusson, Vieira, & Rados, 2015;Kaya, Adapınar, & Özkan, 1997).…”
