Etiology of Mucous Diseases

By Dr. Vishaal Bhat on Wednesday 12 December 2007 with 0 comments



Diseases of oral cavity mucous membranes are among the most difficult chapters in stomatology namely because individual morphae (especially blisters) change rapidly due to mastication and wet environment and their typical form lasts very shortly. A physician has to rely on an anamnesis, evaluation of the course of a disease and auxiliary examinations that help to complete a picture of a disease.


Etiology of mucous diseases is a multi-factorial one. Many effects take part for these diseases to occur: mechanical (traumatizing), thermal, chemical, electro-galvanic effects, radiation, etc. Besides these external effects, internal factors, such as nutritional deficiencies, disorders of iron, lipids, saccharides, vitamins, proteins or minerals metabolism, play a role. It is rare that mucous diseases would be restricted to oral mucosa only, usually they are in a close relationship with general changes of an organism, especially with skin diseases. The variability of changes inside a mouth is determined both by various arrangement of mucosa at different parts of oral cavity, and by saliva composition. Both specific and non-specific immune mechanisms (phagocytic cells and immunoglobulin antibodies) play a role at these processes. The immune system has an important role at oral mucosa diseases and to a large extent determines its resistance against pathologic noxas.

All morphae that are known in dermatology may be found on a sick oral mucosa; except incrustations and scales (squama) that occur at the lips vermilion only. An aphta is typical for oral mucosa only. It begins with a small blister that erodes rapidly and gets covered with fibrin. It is surrounded by a regular inflammatory rim (halo).
