Certain red/white/red-white lesions of the oral cavity have a potential or a higher risk to develop malignancy (oral squamous cell carcinoma [OSCC]). These are broadly termed Oral Potentially Malignant Disorders.
This video aims to throw clarity into this topic as students and dentists alike are usually confused about oral potentially malignant disorders and interchange terms like precancers, precancerous lesions, precancerous conditions and oral potentially malignant disorders. In fact Oral Potentially Malignant Disorder is the right term to use to classify lesions that are precursors to Oral Squamous Cell Carcinoma.
Questions I have tried to address in this video:
1) What’s the deal with precancerous lesions, precancerous conditions and oral potentially malignant disorders? I am confused with these terms.
2) Is epithelial dysplasia a significant predictor of malignant transformation of OPMDs?
3) Besides epithelial dysplasia, can the site and clinical appearance of an OPMD like leukoplakia be a predictor of malignant transformation?

Note:
💡Though "oral cancer" is a blanket term (carcinoma or sarcoma), in this video, the term "oral cancer" is interchangeably used with oral squamous cell carcinoma.
💡The video doesn't go into details of specific/individual OPMDs but gives a list of all OPMDs at the end of the video.
