“…The services of the MRI are needed for other, graver medical requirements that, in the grand scale of things, are more serious than anterior displacement of a A condylar disc. Fortunately, axiographic analysis can, to a large extent, serve as a diagnostic substitute tool for the MRI 23,31 ( fig. 15).…”

Without realizing it, orthodontists may find themselves treating patients suffering from cranio-mandibular disorders, who may be adults, but not necessarily. Both young children and adolescents can also have these problems. Orthodontists often fall into the trap of not recognizing these disorders especially when the clinical signs are discreet or even non-existent. In order to save orthodontists from encountering unpleasant post-treatment surprises, we present in this paper a review of some of the indications of the etiology of craniomandibular dysfunction, how to diagnose it, and the importance of its major clinical signs that can be a great help to them in achieving a keener state of vigilance in this regard throughout orthodontic therapy.

“…According to the philosophy of our school, from a long time, we study both anatomy and function of TMJ using different instruments and protocols. The data are recorded by different group of operators, specialized in different fields, but the diagnosis is interdisciplinary.Using always Axiography and MRI to diagnose the TMD patients, we realized that those two exams are necessary for a full diagnosis of the TMJ pathology [1][2][3].The MRI shows the anatomy of the soft and hard tissues of the TMJ; but, to obtain high-resolution images, the joint must be completely static, any movement meaning a blurred image. On the contrary, the axiography shows the functional aspect of the joint during border movements and, eventually, the functional compensation to the altered anatomy [4].…”

Aim of the study was to compare the Magnetic Resonance Imaging (MRI) and the Computerized Axiography tracings to find out the agreement of the two exams. The results showed that the agreement was very low. MRI and Computerized Axiography record different characteristics of the joints being the MRI a static and the Axiography a dynamic exam. They should be considered complementary and both necessary for a full diagnosis of Temporo-Mandibular Joint Pathology.Keywords: Magnetic resonance imaging, axiography, temporomandibular joint, temporomandibular disorders, temporomandibular diagnosis It has been a great honour receiving the prize for the best basic research poster at the IAAID congress "Consensus Conference -from diagnosis to treatment", 25th -28th October, Krems, Austria. According to the philosophy of our school, from a long time, we study both anatomy and function of TMJ using different instruments and protocols. The data are recorded by different group of operators, specialized in different fields, but the diagnosis is interdisciplinary.Using always Axiography and MRI to diagnose the TMD patients, we realized that those two exams are necessary for a full diagnosis of the TMJ pathology [1][2][3].The MRI shows the anatomy of the soft and hard tissues of the TMJ; but, to obtain high-resolution images, the joint must be completely static, any movement meaning a blurred image. On the contrary, the axiography shows the functional aspect of the joint during border movements and, eventually, the functional compensation to the altered anatomy [4]. This is a very important difference between the two exams and, for this reason, specificity or sensitivity may result very low.The aim of this study was to evaluate the agreement of MRI diagnostics imaging and axiographic tracings to establish if they give the same diagnosis or if they detect different aspects of the TMJ pathology.One hundred and five patients suffering from TMD, aged 16-50 years (mean age: 33 years) were selected for this studyfrom the 1st June 1998 through the 1st December 2003 from among those referred to the Department of Orthodontics, University of Turin, Italy.All subjects underwent magnetic resonance imaging (MRI) (Signa GE Medical Systems) and computerized axiography (Cadiax Ò Diagnostic axiograph and Gamma Dental Software, Gamma Dental) after clinical evaluation. The results showed that the agreement of the two exams is low (Tab. 1). The Kappa Index was 13% and the level of agreement was weak/decent. This result may be due to the fact that axiography shows a functional aspect or a functional compensation, during border movements, while MRI shows the TMJ anatomy in static conditions. The function of the TMJ is very important and the dentists need to know both the anatomy and the function of the TMJ before any therapeutic decision; but the dynamic aspect alone is not enough, and it is important to know the anatomic situation contemporary. The functional aspect re-
