DOH345 Lecture Notes - Lecture 1: Magnetic Resonance Imaging, Ct Scan, Stratified Squamous Epithelium
Document Summary
The oral cavity is lined with stratified squamous epithelium overlying mesenchymal tissue. Buccopharyngeal membrane ectoderm and endoderm come into direct contact with each other. Forms a septum between the mouth and the pharynx. Diagnostic tests are required to have high predictive values, and the more significant the diagnosis, the higher the predictive value must be. The proportion of patients known to have the disease who test positive. The proportion of patients known to not have the disease who test negative. The proportion of all positive results that are true positives. The proportion of all negative results that are true negatives. Is the removal and examination of part or the whole of a lesion. What are the principles of biopsy taking: choose a representative area(s, avoid sloughs and necrotic areas, give anaesthetic around not into lesion. Include margin of normal tissue (sufficient depth and width)
