While the subjects of comparative radiology in our study were patients with TMJ disorder
, recent studies of ZACD were more based on determining its prevalence by including larger groups of dental patients without previous symptomatology related to the stomatognathic system.

Teeth that do not fit together properly are also a leading cause of TMJ disorders

. Their symptoms range from tender facial muscles to agonizing pain and headaches.
Several factors lead to TMJ disorders
that consist of erosion, tearing, inflammation and swelling of the joint, trauma, stress, some dental plaques and bruxism and tooth grinding.
On the other hand, there was a statistically significant difference (p=0.0313) in particular questions; students from Rijeka gave more positive answers than students from Zagreb on disc displacement and osteoarthritis as the most common TMJ disorders
Various factors need to be considered, most imprtant of all factors is the case selection as its clearly evident that arthrocentesis is not going to be effective in patients of TMJ disorders
with advanced internal derangement which results in disc perforation, osteophyte formation and cortical erosion of articular surfaces.14 In some cases where patients are suffering from both myofascial pain dysfunction(MPDS) and joint disrder, arthrocentesis alone is not effective in reducing the pain.8,19 In such cases MPDS should be treated with other means along with arthrocentesis to control the pain.
The patient gave a history of mild hypertension and denied any symptoms of TMJ disorder

There is little, if any, consensus about how to treat TMJ disorder
Malocclusion puts excessive strain on the TMJ and increases the risk of developing TMJ disorder
, jaw stiffness, chronic headaches, and impaired oral function [1, 2].
