Immunological and biochemical markers in oral carcinogenesis: The public health perspective

Abstract

Oral health is an integral component of general health and well being and a basic human right. Dental public health is probably the most challenging specialty of dentistry. Because of the lack of adequate resources among other factors, many people are likely to suffer from dental diseases. Despite great improvements in the oral health status of populations across the world, the burden and impact of dental diseases are still high. This is particularly true among underprivileged groups in both developed and developing communities. Oral diseases and conditions, including oral cancer, oral manifestations of HIV/AIDS, dental trauma, craniofacial anomalies, and noma, all have broad impacts on health and well-being. Oral cancer, the sixth most common cancer worldwide continues to be most prevalent cancer related to the consumption of tobacco, alcohol and other carcinogenic products. Nevertheless, significant reduction in mortality can be achieved by advances in early diagnosis and implementation of multidisciplinary treatment programs leading to improvement of survivorship and better quality of life. The present study was designed to evaluate the immunologic and biochemical markers in oral carcinogenesis using circulating immune complexes (CIC), copper, iron, and selenium concentrations as assessment endpoints. Study results indicated an increase in CIC and copper levels, and a decrease in iron and selenium concentrations in oral cancer patients compared to controls. The implications of these findings for public health are discussed. © 2008 MDPI. All rights reserved.
