Material and Methods
At Tsurumi University Dental Hospital, patients first receive a clinical diagnosis in the initial consultation room and then are sent to various specialized departments for the respective required treatments. The subjects of this study were also examined according to this protocol for the presence or absence of symptoms of TMD based on the objective and subjective symptoms presented. Two groups of patients, those seeking dental treatment and those who were referred due to symptoms of TMD, were
Baseline characteristics
The average age of the TMD patients was less (male: 43.7 ± 16.8; female: 41.9 ± 14.1; total: 42.3 ± 14.7) than that of the dental patients (male: 50.0 ± 16.9; female: 49.0 ± 15.7; total: 49.4 ± 16.2; P < .01). Fifty-eight percent of the dental patients were female, whereas 80.2% of the TMD patients were female, which represented a significant difference in the percentages of males and females (P < .01) between the 2 conditions.

Discussion
Temporomandibular disorders result from several factors, such as occlusion, abnormal condyle position and disk position, excessive muscle activity, physiological and psychological variables, and systemic factors. To date, several epidemiological,7, 9, 12, 14, 26 anatomical,5, 6, 13, 19, 21 and diagnostic imaging studies24, 27, 28, 29, 30, 31, 32, 33 have been conducted on the factors related to TMD. The present survey also examined the relationship between the symptoms of TMD and the criteria

A controversy with respect to occlusion
2016, Japanese Dental Science ReviewCitation Excerpt :A number of techniques, such as TMJ imaging through TMJ radiography using panoramic equipment, tomography, computed tomography (CT), and magnetic resonance imaging (MRI) are all useful in this regard, as well as assessing bone changes, although the accuracy is different among the respective means [29–33]. It is interesting that the patients with deformed condyles do not always indicate clinical symptoms [34,35]. Even without TMD symptoms, this does not indicate whether or not the condyle is deformed or stable.
Orthodontic Implications of Growth and Differently Enabled Mandibular Movements for the Temporomandibular Joint
2012, Seminars in OrthodonticsCitation Excerpt :They found some extreme ranges of occlusion were the domain of patients with TMD, but occlusions in most patients were within normal ranges. It was demonstrated by Takayama et al104 that the symptoms of TMD correlated with age, sex, and dental and occlusal conditions. However, the prevalence of bone change in the condyle correlated poorly with these variables in patients with or without TMD.
