Aim: This study aimed to investigate whether non-ionizing radiation emitted by smartphones is likely cause genotoxic effects on oral epithelial cells. Methods: Thirty adults were distributed into two groups according the mobile phone brand used, namely Samsung (Samsung, Seoul, South Korea) and Apple (Apple, California, USA). The material was collected with gentle swabbing of right left buccal m...

Lead (Pb), a toxic contaminant metal used in many important industrial processes, is widely used in batteries, paint vanishes, in pipe covering and in welding. The exposure showed a high risk of human health and development of several types of cancers. A total of 64 male workers in Hyderabad battery unit in Mahaboobnagar District, Andhra Pradesh were investigated for genetic damage in buccal ce...

Hairdressers are exposed daily to chemical substances, such as dyes, chemical straighteners and curling chemicals, which can be absorbed, inhaled or possibly ingested. We analyzed the frequency of micronuclei (MNC) in exfoliated cells of the buccal mucosa of 50 hairdressers and 50 controls in Pelotas, RS, Brazil. An assessment was carried out on the incidence of MNC, binucleated cells (BNC), br...

Preparations of salivary glycoproteins inhibited the attachment of certain indigenous oral streptococci to human buccal epithelial cells and fostered the desorption of previously attached bacteria. The adherence-inhibiting and desorptive activities of the glycoproteins correlated with their ability to aggregate these organisms. Pretreatment of glycoprotein preparations with certain blood group ...

Focal epithelial hyperplasia or Heck’s disease is a benign, rare viral disease of the oral cavity and is associated with human papillomavirus 13 and 32 (HPV-13 and HPV-32). Most patients are children but adults may also be at risk. Clinically, the patients have multiple small white or pink papules on the mucosal surface of the lips, buccal mucosa and the tongue. In Iran, this disease seems to b...

The present study was aimed to investigate the frequency of micronuclei and other nuclear anomalies in alcoholic subjects. The present study included 100 subjects out of which 54 were alcoholics (23 smokers and 31 non smokers) and 46 subjects (non smokers) were healthy controls.The average age of alcoholics was of 44.185±4.434 years, very close to that of control individuals which was 41.281±6....

Human biomonitoring using the micronucleus (MN) assay on exfoliated buccal cells is an invasive approach for the assessment of genetic damage in exposed populations. To determine the genotoxic effects of spray painters, MN assay was carried out in exfoliated buccal epithelial cells of 94 spray painters and 80 controls. From each individual, 2,000 exfoliated buccal cells were analyzed. The indiv...

background there is a potential risk for malignancy in patients with diabetes mellitus. theoretically, a noninvasive method for detection of precancerous changes can be conducted on oral exfoliated cell smears. objectives in this study, the immunocytochemistry of p53 in exfoliated oral mucosal cells in patients with type 2 diabetes was investigated. patients and methods oral mucosal smears were...
