  • 1. Texts are organized differently Example: Neville et al set up chapters on the basis of disease type (e.g. Soft tissue tumors or epithelial pathology) Wood and Goaz list lesions as soft or bony type. The Oral Medicine review focuses on literature review of selected diseases. 2. The Oral Medicine text has excellent tables for drug therapy; for example systemic and topical preparations of steroids and other systemic therapies. 3. Neville and Lynch the most extensive re Oral Med.
  • Increasing Prevalence in younger people (m/f) Diet: NIH: decrease in CA with fruit/veg/vit C, fiber; In males carotene and Vit E decreased risk Charcoal grilled/pickled/smoked fish, meats not correlated Risks: tobacco / alcohol (may permeabilize membrain (also with sodium lauryl sulfate in toothpaste (static studies/ few prospective studies Viral and oncogene influences Infection with HPV or HSV (genital) HPV with oral lesions
