Table 2 Relationship between capsular width assessed by ultrasonography and TMJ pain
From: Can ultrasonography be used to assess capsular distention in the painful temporomandibular joint?
| Capsular width (mm) | p-value | |
|---|---|---|
| Total patients (N = 174 joints) | ||
| Pain ( +) | 2.04 ± 0.49 | < 0.001* |
| Pain ( −) | 1.37 ± 0.41 | |
| Unilateral pain patients (N = 47 paired joints) | ||
| Pain ( +) | 2.04 ± 0.52 | < 0.001* |
| Pain ( −) | 1.37 ± 0.36 | |
| Pain duration | ||
| More than 3 months | 2.15 ± 0.52 | 0.081 |
| Less than 3 months | 1.97 ± 0.45 |
