Randomized clinical trial of primary treatment for temporomandibular joint disk displacement without reduction and without osseous changes: A combination of NSAIDs and mouth-opening exercise versus no treatment

Most of the studies favored the use of exercises alone or as part of a general regimen to treat people with arthrogenous TMD, including disk displacements with or without reduction.

“Although the results were mixed, most of the studies favored the use of exercises alone or as part of a general regimen to treat people with arthrogenous TMD, including disk displacements with or without reduction.58,68,84 -86”

Regarding active mouth opening, a nonsignificant effect was found between general jaw exercises and education, splint therapy, or a control group when pooling 3 studies.

When pooling results of studies investigating the effectiveness of exercise alone or in combination with other conservative therapies on pain intensity, there was no statistically significant difference in pain between exercise and control groups.

“When pooling the results of the studies investigating the effectiveness of exercise alone or in combination with other conservative therapies on pain intensity, 58,61,68,86 we found that there was no statistically significant difference in pain between exercise and control groups.”

When pooling was focused on those studies including only a control group, similar results were found, although the SMD increased (SMD=1.11; 95% CI -0.73, 2.94).
