JIA disease course in the TMJs and mandibular growth rotation; rotation in controls for comparison
| MPA* decrease more than 2 degrees | MPA change less than 2 degrees | MPA increase more than 2 degrees | |
|---|---|---|---|
| Healthy control group (n = 16) | 10 | 6 | |
| Normal TMJ** group (n = 11) | 8 | 3 | |
| Abnormal TMJ group (n = 15) | |||
| - Consistently progressing (n = 1) | 1 | ||
| - Varying (n = 2) | 1 | 1 | |
| - Stable (n = 6) | 2 | 3 | 1 |
| - Slightly improving (n = 4) | 2 | 2 | |
| - Greatly improving (n = 2) | 2 |
* MPA = Mandibular plane angle
** TMJ = Temporomandibular joint
