Explanation:
Detailed explanation-1: -The entire surface of the oral mucosa is covered by squamous stratified epithelium. This is a highly organized, avascular, and semipermeable tissue whose thickness and degree of keratinization varies according to the location in the oral cavity and the area’s functional and mechanical requirements.
Detailed explanation-2: -The inability of the molecules to enter the epithelium prevents them from gaining access to the proliferative cells in the basal and intermediate cell layers. Tobey et al. showed that the squamous epithelium is damaged by acid, causing separation of epithelial cells due to damage of tight junctions.
