Abstract |
Bone scan is a very sensitive diagnostic imaging test
for detecting bone and joint disorders. So it might be
useful in the diagnosis of temporomandibular disorders
of the joint origin. Thus, the effectiveness of bone
scan for detecting temporomandibular joint(TMJ)
diseases and differentiating the TMJ disc displacement
from the TMJ arthritis was evaluated. Bone scan was
done in 21 patients with TMJ disc displacement(l3
unilaterally affected, 8 bilaterally affected), 26
patients with TMJ arthritis(23 unilateral, 3
bilateral), and 39 volunteers with no signs, symtoms,
or history of TMJ disease TMJ simple uptake rate(SUR)
and difference of both TMJ SUR were calculated from the
100,000 count lateral image of head and neck region in
Tc-99m MDP bone scan. Transcranial and panorama X-ray
examination was also done in all patients. TMJ SUR(%)
were 1.673±0.606 in TMJs affected with arthritis,
1.350±0.351 in TMJs affected with disc displacement,
and 1.084±0.172 in TMJs of controls Significant
differences were demonstrated among them(p〈001).
Difference of bith TMJ SUR was highest in patients with
unilateral TMJ arthritis(0.608±0.533, p〈001), and
there is no significant difference between that of
controls and that of unilateral TMJ disc displacement
patients(0.062±0.063 vs 0.122±0.100). TMJ SUR of
joint with bone change on X-ray finding was not
significantly different from that of joint with normal
X-ray finding. Those in patients with unilateral TMJ
disc displacement(69.6% and 87% vs 23.1% and 23%). The
proportions of patients with increased TMJ SUR and
difference of both TMJ SUR(〉mean+2SD of controls) in
unilateral TMJ arthritis patients were significantly
higher than those in patients with unilateral TMJ disc
displacement(69.6% and 87% vs 23.1% and 23%).
Conclusively, bone scan may help to detect TMJ disease
and differentiate TMJ disc displacement from TMJ
arthritis. |
