Method of help for the diagnosis of the temporomandibular joint internal derangements. Discriminant analysis applied to the temporomandibular derangements.
OBJECTIVE
The purpose of the study is to find an objective method of help for the clinician in the diagnosis of the pathology of the temporomandibular joint, different of the image methods habitually utilized until this moment.


METHODS
This study is based initially on the data obtained of a sample of 1164 patients with symptoms and/or signs of pathology of the temporomandibular joint. Nine different and excluding diagnostic groups settled down, according to the classification of the American Academy of Orofacial Pain (AAOP), in collaboration with the International Headache Society (IHS). We realized magnetic resonances to the patients and were selected those that adjust to the clinical criterion and of diagnosis for the image, and could only in a diagnostic group. Finally 449 patients were selected, 390 women and 59 men.


RESULTS
The results obtained (expressed in percentage of well classified cases) by means of the proposed method were: Arthrosis 98.9%, Anterior Disk Displacement with Reduction (ADDR) 87.5%, Anterior Disk Displacement without Reduction (ADD) 100%, Capsulitis 100%, Disk Immobile (DIN) 97.9%, Hypermobility Condylar (HC)95.8%, Lateral Displacement Without Reduction (LD) 100%, Pathology Muscular (PM)100%, Disk Hipomobile (DHM) 86.4%.


CONCLUSIONS
The proposed method reaches a fine percentage of successes in the diagnosis of these processes good enough, through its effectiveness as for its cost and should be considered an alternative in the diagnosis of temporomandibular derangements.
