Dentist's Delay or Dexterity to Diagnose the Deadly: A Clinico-radiological Series of Oral Malignancies Exhibiting Varied Presentations in the Tamil Nadu Rural Belt.

Oral cancer is the sixth most common malignancy globally with a wide geographic variation. India is the second largest consumer and third largest producer of tobacco in the world. One-third of the global burden of oral cancer is predominantly attributed to high prevalence of tobacco consumption. The highest incidence and prevalence of oral squamous cell carcinoma is found in the Indian subcontinent particularly in the lower socioeconomic strata, due to an increase in the deleterious habits of potent, proven carcinogens like smoking, chewing tobacco, betel quid and areca-nut. Also, there is a delayed presentation of oral cancer in India, as approximately 50% of patients are diagnosed at stage III or IV. In this article, we report five varied presentations of well differentiated oral squamous cell carcinoma from rural belt of Tamil Nadu. All the cases were reported late to diagnose. Clinical and radiological staging plays a pivotal role to stage an oral malignant patient which aids in guiding him to a proper treatment plan. Early diagnosis along with patient counselling is of vital importance for the prognosis of the patients with oral malignancies. Also, it is an utmost important duty of the health care professionals to create awareness on oral cancer especially in rural areas. For this reason, dentists play a very significant role in the early detection and prevention of oral malignancies.
