The mouth is also subject to sudden changes in temperature and pH meaning it must be able to adapt to change quickly. The mouth is the only place in the body which provides the sensation of taste. Due to these unique physiological features, the oral mucosa must fulfil a number of distinct functions.
Granulation tissue is composed of tissue matrix supporting a variety of cell types, [3] most of which can be associated with one of the following functions: formation of extracellular matrix; operation of the immune system; vascularisation; An excess of granulation tissue (caro luxurians) is informally referred to as hypergranulation or "proud ...
The gums are part of the soft tissue lining of the mouth. They surround the teeth and provide a seal around them. They surround the teeth and provide a seal around them. Unlike the soft tissue linings of the lips and cheeks, most of the gums are tightly bound to the underlying bone which helps resist the friction of food passing over them.
In human anatomy, the mouth is the first portion of the alimentary canal that receives food and produces saliva. [2] The oral mucosa is the mucous membrane epithelium lining the inside of the mouth. In addition to its primary role as the beginning of the digestive system, the mouth also plays a significant role in communication.
A pulp polyp, also known as chronic hyperplastic pulpitis, is a "productive" (i.e., growing) inflammation of dental pulp in which the development of granulation tissue is seen in response to persistent, low-grade mechanical irritation and bacterial invasion of the pulp. [1] [2]
The mucosa of the cheeks and floor of the mouth are freely moveable and fragile, whereas the mucosa around the teeth and on the palate are firm and keratinized. Where the two tissue types meet is known as a mucogingival junction. There are three mucogingival junctions: on the facial of the maxilla and on both the facial and lingual of the mandible.
The microscopic appearance of a pyogenic granuloma consists of highly vascular granulation tissue. Inflammation is present. The lesion may have a fibrous character if it is older, and the surface may have ulcerations. Pyogenic granulomas rarely occur in the conjunctiva, cornea, or connective tissue of the eye following minor local trauma.
When gingival hyperplasia is confined to one area of the jaw, this is when it is termed an epulis fibrosa, caused by an increase in collagenous tissue with varying cellularity. [12] It may be sessile or pedunculated and is composed of fibrosed granulation tissue. Fibrous epulides are firm and rubbery, and pale pink in color.
