J Family Med Prim Care 2021 Jan 30;10(1):572-577. Epub 2021 Jan 30.

Department of Oral Medicine and Radiology, Sathyabama Dental College and Hospital, Chennai, India.

Background: Globally, the sixth most common malignancy is oral cancer, which is predominantly due to consumption of potent, proven carcinogens which includes smoking and smokeless form of tobacco and areca nut. Habits associated oral malignancies are mostly preceded by clinically asymptomatic oral lesions collectively referred under the umbrella term as oral potentially malignant disorders (OPMDs). There is a delayed presentation of oral pre cancer and oral cancer in India, as approximately 50% of patients are diagnosed at last stage since the asymptomatic pre cancer lesions are missed by oral physicians/dentists either due to lack of timely communication and habit counseling, lack of knowledge, or inappropriate attitude, putting all in a nut shell --- sheer lack of empathy and commitment towards patient care and society.

Microbial communities and gene contributions in smokeless tobacco products.

Appl Microbiol Biotechnol 2020 Dec 12;104(24):10613-10629. Epub 2020 Nov 12.

Division of Laboratory Sciences, Centers for Disease Control and Prevention, 4770 Buford Highway, NE MS 110-03, Atlanta, GA, 30341-3717, USA.

Smokeless tobacco products (STP) contain bacteria, mold, and fungi due to exposure from surrounding environments and tobacco processing. This has been a cause for concern since the presence of microorganisms has been linked to the formation of highly carcinogenic tobacco-specific nitrosamines. These communities have also been reported to produce toxins and other pro-inflammatory molecules that can cause mouth lesions and elicit inflammatory responses in STP users. Read More
