| Title |
Placing a Restoration or Prostheses That Introduces an Occlusal Interference Does Not Necessarily Cause TMD Symptoms |
| Clinical Question |
Will placing a restoration or prosthesis that introduces an occlusal interference always cause TMD symptoms? |
| Clinical Bottom Line |
In patients with myofascial pain, placing a restoration or prosthesis that introduces an occlusal interference will not necessarily induce TMD symptoms. |

Comments on
The Evidence |
Validity:
In this crossover, randomized controlled trial, participants were similar at the start of the study. Measurements were recorded under several conditions (interference-free, dummy-interference, and active interference) by placing gold foil on an occlusal or vestibular surface. All seven female participants completed the study with adequate follow-up. Recall bias was unlikely, because there was no competing interests.
Perspective:
The study was well constructed in regards to treatment of the participants and the efficacy of gathering the data. The participants were only female, which the literature suggests more commonly develop TMD; therefore, based upon the study's findings, this limited population was probably appropriate. However, due to the brief nature of the study and small sample size, long-term effects of occlusal interferences relative to TMD symptoms could not be drawn; however, conducting a lengthier study with a larger sample size would, in turn, have other ethical drawbacks. |
| Applicability |
When a patient develops TMD symptoms following the placement of a restoration, many potential causes (including occlusal interferences) should be considered. |
