Abstract
OBJECTIVE
To study and estimate the impact of clinical, somatosensory, and psychosocial variables associated with the concomitant presence of temporomandibular joint (TMJ) pain in patients with TMJ clicking.
MATERIALS AND METHODS
Ninety-three individuals composed the sample: patients with painful TMJ clicking (n = 47) and patients with painless TMJ clicking (n = 46). Four categories of data were evaluated: clinical features (gender, maximal interincisal distance (MID), side of complaint, age); bruxism (sleep bruxism (SB), awake bruxism (AB)); somatosensory (mechanical pain threshold (MPT), wind-up ratio (WUR), pressure pain threshold (PPT), conditioned pain modulation (CPM)); and psychosocial (Pittsburgh Sleep Quality Index (PSQI), pain vigilance and awareness questionnaire (PVAQ), Pain Catastrophizing Scale (PCS), Tampa Scale for Kinesiophobia for Temporomandibular Disorders (TSK/TMD), Oral Behaviors (OBs)).
RESULTS
Female gender, AB, WUR, CPM, PSQI, PCS, and OBs significantly (p < 0.05) increased the chance of the concomitant presence of TMJ pain in patients with TMJ clicking. On the other hand, MID, MPT, and PPT significantly (p < 0.05) decreased this chance. The other variables had no association.
CONCLUSION
It can be concluded that being a woman, having AB, hyperalgesia in WUR, less efficient CPM, poor sleep quality, pain catastrophizing, and harmful OBs significantly increased the chance of the concomitant presence of TMJ pain in patients with TMJ clicking. In the opposite, high figures of MID, MPT, and PPT decreased the chance.
CLINICAL RELEVANCE
Most patients with TMJ clicking usually postpone seeking treatment until the clicking truly disturbs or there is a concomitant presence of TMJ pain. Understanding the variables associated with this concomitance can be important in clinical practice.
