Clinical oral investigations
-
The aim of the present study was to evaluate the pressure pain threshold (PPT), tactile threshold (TT) and pain intensity as measured on a Visual Analogue Scale (VAS) in patients with pain in the orofacial region. Twenty-six patients with myogenous pain (7 ss), myogenous and capsular pain (11 ss) or neuropathic pain (8 ss) participated in the study. At baseline, the PPT was evaluated using an algometer and the TT using von Frey hairs. ⋯ In patients with myogenous and capsular pain, as well as in patients with neuropathic pain, the PPT increased after active treatment, while it decreased in the group with pure myogenous pain. The VAS score decreased in all groups. Regarding psychological profiles, a variety of characteristics were observed and the scale for sleeping problems was especially elevated in a majority of the patients.
