To provide a systematic description of clinical findings and psychosocial factors in patients suffering from atypical odontalgia (AO). ⋯ A majority of the AO patients reported persistent, moderately intense intraoral pain that in most cases had an onset in conjunction with dental treatment. AO patients had more comorbid pain conditions and higher scores for depression and somatization. Significant limitation in jaw function and significantly lower scores on quality of life measures were found for AO patients compared with controls.

To determine intra- and interrater agreement of the pressure pain threshold (PPT) values for children reporting orofacial pain related to temporomadibular disorders and symptom-free subjects when the mean of 3 consecutive measurements or the mean of the last 2 consecutive measurements was considered. ⋯ The lower levels of reproducibility for the measurements obtained on different days in the children who reported pain may have been related to instability of their clinical signs and symptoms, and a PPT assessment based on the mean of 3 consecutive measurements or the procedure of discarding the first measure should be considered for such evaluations, especially when they are conducted by different raters. Algometry was shown to be a reliable tool for the evaluation of pain threshold in the masticatory structures of children.

To characterize the level of impairment of oral health-related quality of life (OHRQoL) in a temporomandibular disorder (TMD) patient population. ⋯ OHRQoL was markedly impaired in TMD patients. The level of OHRQoL varied across diagnostic categories but more across Axis II, ie, the psychosocial axis; the variation was reflected especially in their level of graded chronic pain.

To investigate whether trigeminal manifestations of pain, sensitization, and vasomotor responses following the intradermal injection of capsaicin to the foreheads differ from manifestations following injection of capsaicin in the forearms of healthy humans. Dose dependency and sex-related differences of the evoked responses were also studied. ⋯ Capsaicin-evoked sensory and vasomotor manifestations were different in the forehead and forearm. The differences are most likely due to the differences in innervation density and neurovascular activity. The capsaicin-induced effects were demonstrated to be dose-dependent and sex-related phenomena.

(1) To use psychometrically sound measures to characterize the pain levels and pain-related interference associated with recurrent aphthous ulcers (RAU); (2) to determine whether subjects with RAU report clinically significant psychologic symptoms; and (3) to examine the relationships between physical characteristics and self-reported psychologic symptoms, pain, and pain-related interference. ⋯ RAU is a moderately painful condition causing some impairment in functioning. Self-reported pain intensity of a sore does not appear to be influenced by psychologic characteristics. However, pain-related interference appears to be related to psychologic and not physical characteristics.
