Abstract
The aim of this study was to investigate the relationship between the presence or absence of anterior tooth contact and the changes in temporomandibular joint space. The study sample consisted of 32symptom-free dental students and 79
craniomandibular
disorders patients with unilateral joint dysfunction. The two groups were categorized into control group or experimental group, respectively. Recordings of the number and distribution of occlusal contacts were made by T-Scan system. Transcranial
radiographs were using of accurad-100 head positioner. Measured items in transcranial radiographs were anterior, superior, posterior joint space and relative condylar position to deepest position of glenoid fossa. According to the presence or
absence of
anterior tooth contact, each group was subdivided and compared with each other with respect to TM joint space. Data were processed and tested with SPSS/PC + package. The results of the study showed that the joint space in control group were wider
than
those of experimental group and the difference of the width of joint space was more remarkable in subjects with anterior contact between control group and experimental group, However, in same group whether the presence of anterior tooth contact
could
hardly affect the difference of the width of joint space. And anterior tooth contact in group are more frequent than in experimental group.
