Adjunctive Techniques and Diagnostic Aids in the Early Detection of Oral Premalignant Disorders and Cancer: An Update for the General Dental Practitioners.

Oral cancer (OC), a potentially fatal disease, is a major health concern across the world. It is reported to be the sixth most common cancer in the world with a disappointingly low 5-year survival rate, despite major advances in onco-medicine in the past three decades. The low 5-year-survival rate is associated with late diagnosis of the disease, while OC diagnosed at early stages enjoy a much higher 5-year-survival rate, comparatively.

Lactate Dehydrogenase: The Beacon of Hope?

Lactate dehydrogenase enzyme (LDH) helps in the conversion of glucose into pyruvic acid during aerobic glycolysis and is found in the cytoplasm of most cells in the human body. When oxidative stress occurs in the body, LDH may be released extracellularly and its level is usually indicative of the severity of tissue damage. LDH has proved to be an inestimably resourceful marker in early prediction of serious diseases involving extensive tissue or cellular damage.

Autophagy: The "Pac-Man" within Us-Ally or Adversary?

Autophagy, first described by the Belgian biochemist Christian De Duve in 1963, is derived from the Greek word "autóphagos," which means "self-devouring."

The implication of defective autophagy in various human diseases has been well documented.
