Randomized Controlled Trial Comparative Study Clinical Trial
Topical application of capsaicin for the treatment of localized pain in the temporomandibular joint area.
To determine the effectiveness of topical capsaicin cream application on localized pain in the temporomandibular joint (TMJ) area. ⋯ The factor of time had a major effect in the non-specific improvement of the parameters assessed. The placebo effect played an important role in the treatment of patients with pain in the TMJ area.

To investigate and compare absolute pressure-pain threshold (PPT) levels and ratios between craniofacial test and reference sites during consecutive PPT recordings, as well as over a 6-month period, in healthy individuals. This study also investigated PPT differences between genders and the clinical usefulness of different reference sites in the craniofacial region. ⋯ This study shows that absolute PPT levels in healthy individuals change significantly during consecutive PPT recordings, as well as over a 6-month period; this limits the usefulness of such measurements. This study also shows that the use of relative PPTs with the FRO as a reference site is useful, both for comparison between groups and for longitudinal studies.

To determine potential differences in predictive models of acute temporomandibular disorder (TMD) patients divided into groups based on the physiologic characteristics of their TMD. ⋯ The factors that predict which acute TMD patients are most likely to seek additional treatment vary depending on the physiologic basis of their TMD. This suggests that acute TMD patients may benefit from different modalities of treatment, depending on the type of TMD with which they present.

Patients with different facial pain/headache pathologies usually complain of numerous accompanying symptoms relative to systemic dysfunctions or to the patient's personality characteristics. The purpose of this work was: (1) to determine the prevalence of accompanying symptoms in groups of patients with temporomandibular joint (TMJ) dysfunction and other types of facial pain or headache disorders, (2) to assess the patients' personality characteristics and anxiety levels, and (3) to see whether significant differences were found between the groups. ⋯ It is concluded that some types of headache and facial pain seem to correlate with the presence of a number of accompanying symptoms and with some changes in personality. These changes are particularly relevant in patients with chronic daily headache and facial pain disorder. In contrast, patients with TMJ intracapsular disorders tended to show a low prevalence of accompanying symptoms and a normal personality profile.

Randomized Controlled Trial Clinical Trial
Does the ovarian cycle influence the pressure-pain threshold of the masticatory muscles in symptom-free women?
To test the hypothesis that the ovarian cycle influences the pressure-pain threshold of the masticatory muscles. ⋯ In healthy subjects, there is a link between mechanical sensitivity of the masticatory muscles and fluctuation of the ovarian hormones. The relationship between PPTs of the masticatory muscles and the ovarian cycle should be also investigated in patients with temporomandibular disorders and/or orofacial pain conditions.
