Atlanta Oral Pathology, Emory Decatur Hospital, Emory University School of Medicine, 2701 N. Decatur Road, Decatur, GA, 30033, USA.

White lesions of the oral cavity are quite common and can have a variety of etiologies, both benign and malignant. Although the vast majority of publications focus on leukoplakia and other potentially malignant lesions, most oral lesions that appear white are benign. This review will focus exclusively on reactive white oral lesions. Read More

Metabolic Activation and Carcinogenesis of Tobacco-Specific Nitrosamine N'-Nitrosonornicotine (NNN): A Density Function Theory and Molecular Docking Study.

Int J Environ Res Public Health 2019 Jan 9;16(2). Epub 2019 Jan 9.

Beijing Key Laboratory of Environmental & Viral Oncology, College of Life Science and Bioengineering, Beijing University of Technology, Beijing 100124, China.

N'-nitrosonornicotine (NNN) is one of the tobacco-specific nitrosamines (TSNAs) that exists widely in smoke and smokeless tobacco products. NNN can induce tumors in various laboratory animal models and has been identified by International Agency for Research on Cancer (IARC) as a human carcinogen. Metabolic activation of NNN is primarily initiated by cytochrome P450 enzymes (CYP450s) via 2'-hydroxylation or 5'-hydroxylation. Read More

Oral health consequences of smokeless tobacco use.

Indian J Med Res 2018 Jul;148(1):35-40

WHO Collaborating Centre for Oral Cancer; King's College London, London, UK.

Smokeless tobacco (SLT) use has many oral effects including oral cancer, leukoplakia and erythroplakia, oral submucous fibrosis (if mixed with areca nut), loss of periodontal support (recession) and staining of teeth and composite restorations. This review was aimed to provide information to identify oral lesions that occur due to the use of smokeless tobacco so that effective interventions can be undertaken to reduce morbidity and mortality from the use of SLT.

Molecular Pathogenesis of Chewable Tobacco.

J Coll Physicians Surg Pak 2018 May;28(5):381-385

Department of Biochemistry, Ziauddin University, Clifton, Karachi.

In Pakistan, extensive use of several precarious chewable tobacco formulations has made oral cancer the second leading malignancy. Selection of literature was done by a survey of studies published from 1990 to 2017 mainly, from PUBMED and few from other search engines, on naswar, gutka, areca nut and betel quid, which included published reviews, original articles and other data sources on chewable tobacco, its epidemiology, pathological implications, and psychological effects. These studies have revealed that the chemicals in these formulations bind and mutate DNA of oral mucosa through down regulating cellular repair pathways and upregulating genetic networks associated with pathogenesis.

Use of rodent data for cancer risk assessment of smokeless tobacco in the regulatory context.

Authors:
Robert Nilsson

Regul Toxicol Pharmacol 2017 Aug 16;88:338-348. Epub 2017 Jun 16.

Vinča Institute of Nuclear Sciences, Laboratory for Physical Chemistry, University of Belgrade, Vinča, Serbia. Electronic address:

To support risk management decisions, information from different fields has been integrated in this presentation to provide a realistic quantitative cancer risk assessment of smokeless tobacco. Smoking among Swedish men is currently below 10%, while about 20% use a special smokeless tobacco (snus) as a substitute for cigarettes. Epidemiological data and molecular biomarkers demonstrate that rodent bioassays with tobacco specific nitrosamines (TSNA) overestimate cancer risk from snus by more than one order of magnitude.

Tobacco Use, Oral Health, and Risk of Parkinson's Disease.

Am J Epidemiol 2017 04;185(7):538-545

Few studies have investigated the associations between use of Swedish moist snuff (snus), associated poor oral health, and risk of Parkinson's disease (PD). We followed 20,175 participants who were free of PD in 1973-1974 in Uppsala, Sweden, until the end of 2012. We used Cox proportional hazards regression models to estimate hazard ratios and corresponding 95% confidence intervals for the associations between tobacco use, oral health indicators, and PD risk.

The aim of this study was to identify palatable additives which have a significant protective action against soft tissue changes in the oral cavity caused by Swedish smokeless tobacco ("snus"), and that satisfy existing legal requirements. Although the cancer risk from snus is extremely low, long term use may result in highly undesirable keratotic lesions and associated epithelial abnormalities in the oral cavity. The rat forestomach, which is vulnerable to the irritative action of non-genotoxic compounds like butylated hydroxyanisole, propionic acid as well as snus, was chosen as an experimental model.

Oral squamous cell carcinoma: Key clinical questions, biomarker discovery, and the role of proteomics.

Arch Oral Biol 2016 Mar 25;63:53-65. Epub 2015 Nov 25.

School of Medicine and Medical Science, UCD Conway Institute of Biomolecular and Biomedical Research, University College Dublin, Dublin, Ireland.

Background: The molecular and cellular mechanisms underlying the pathogenesis of oral squamous cell carcinoma (OSCC) are relatively poorly understood and remain a subject of significant importance. However, it is well established that OSCC is associated with a variety of risk factors and notably, the high incidence rates of OSCC found in developing countries are attributable to exposure to different forms of smokeless tobacco. Despite this, the way these factors contribute to the disease pathogenesis and, in particular, the transformation from oral premalignant lesions (OPLs) to primary tumor remains unknown. Read More

White lesions in the oral cavity: clinical presentation, diagnosis, and treatment.

Semin Cutan Med Surg 2015 Dec;34(4):161-70

Departments of Orofacial Sciences, Radiation Oncology, and Pathology, and the Helen Diller Comprehensive Cancer Center, University of California, San Francisco, California, USA.

White lesions in the oral cavity are common and have multiple etiologies, some of which are also associated with dermatological disease. While most intraoral white lesions are benign, some are premalignant and/or malignant at the time of clinical presentation, making it extremely important to accurately identify and appropriately manage these lesions. Due to their similar clinical appearances, it may be difficult sometimes to differentiate benign white lesions from their premalignant/malignant counterparts. Read More
