Abstract:
Pain, a major symptom of stomatological disease, usually leads to a specialist consultation. Most commonly it is caused by dental caries and differs in nature and in intensity according to the stage of disease: dentinitis, pulpitis, desmodontitis and dental abscess. Added to this is peridental pain and the pre- and post-operative pains related to these diseases. Almost all oral-maxillary pathology is painful, be it boney such as in osteomyelitis and fractures, mucosal in gingivo-stomatitis and aphthous ulcers, or tumourous. However, besides the "multidisciplinary" facial pains such as facial neuralgia and vascular pain, two pain syndromes are specific to stomatology: pain of the tempero-mandibular joint associated with problems of the bite and glossodynia, a very common somatic expression of psychological problems.
