| Title |
Patients Suffering from Temporomandibular Disorder (TMD) Symptoms Are Found to Have More Non-Functional Tooth Contact than Otherwise Healthy Individuals |
| Clinical Question |
Do TMD patients have teeth in contact more often than non-TMD individuals? |
| Clinical Bottom Line |
Patients suffering from TMD symptoms are found to have more non-functional tooth contact than otherwise healthy individuals. However, further study is needed for validity. |

| #1) 24447128 | Funato/2014 | 24 | Case Control Study | | Key results | Patients with TMD recorded a higher frequency of non-functional
tooth contact than the healthy subjects (35.0% vs. 9.6%, P < 0.001).
The frequency of non-functional tooth contact had a tendency to be higher when the subject was working than when relaxing (51.4% +/- 13.9% vs. 37.0% +/- 15.5%; P = 0.099).
| | #2) 17717957 | Chen/2014 | 24 | Case Control Study | | Key results | Patients with myogenous pain recorded a significantly higher frequency of wake-time nonfunctional tooth contact than the control group (median of 34.9% with a range of 26.5% to 41.3% for patients; median of 8.9% with a range of 2.3% to 14.3% for controls; P < .001). | |

Comments on
The Evidence |
Out of the 24 patients in each study (a relatively small sample), non-functional tooth contact was higher in TMD/myogenous pain patients than healthy individuals. The method used to acquire the data, via email and wrist vibrators, relies on the patient's recording of an average day. These methods interrupted daily events, which may have subsequently brought attention to the subconscious actions of the subject, who then made conscious oral corrections. |
| Applicability |
Patients suffering from TMD symptoms spend more time in non-functional occlusion, which may lead to in increase in symptoms during times of stress. If the patient is aware of this occurrence, they may be able to change their occlusal habits and decrease their TMD symptoms, but more study is needed. |
