Abstract
A prognostic investigation was undertaken on twenty-two TMD patients with only reciprocal clicking noise. The purpose was to understand the association between the prognoses, which were no clicking noise, reducing noise and no change, and the contributing factors, such as duration of noise, type of treatment procedure, duration of treatment, occlusal factor, parafunctional habits and psychological factors.
The results were as follows;
In a comparison of the above mentioned prognostic groups with each other, the group with no changed clicking had a longer duration of clicking history than the group with no click (p<0.05).
No significant difference, however, was found in the other factors.
No significant difference was found between the group with only click (22 cases) and the group with clicking noise with pain (36 cases) or the group with closed lock (19 cases), as to the occlusal factors and parafunctional habits.
At the time of recall of twenty-two patients, no cases were observed which become to have painful or to have fallen into closed lock.
