Neurocognitive Functioning in Patients with Painful Temporomandibular Disorders.

Aim: To investigate psychosocial factors in painful TMD (pTMD) which could have consequences for mastering chronic pain.

Methods: Our study included 22 patients (20 women, 2 men) with pTMD, refractory to conservative treatment, and 19 healthy controls. The control group was matched for gender, age, and educational level, and IQ tested on the Wechsler Abbreviated Scale of Intelligence.

High Pain Intensity is a Risk Factor of Non-Resolving TMD: A Three-Year Follow-Up of a Patient Group in a Norwegian Interdisciplinary Evaluation Program.

Purpose: To investigate the outcome of patients with long-term refractory temporomandibular disorders (TMD) three years after a Norwegian interdisciplinary evaluation program with attention to patient satisfaction, function, pain, and psychosocial variables.

Patients And Methods: The study population consisted of 60 long-term refractory TMD patients who were investigated by a Norwegian interdisciplinary team. A questionnaire that covered medical history, function, pain, lifestyle factors, TMD-status and follow-up from their general medical practitioner (GMP) was sent to the patients three years after the evaluation.

Self-reported dental anxiety and injection phobia among individuals with tattoos and piercings.

Injection phobia and dental anxiety can, in severe cases, lead to avoidance of necessary treatment. The aim of this pilot study was to investigate self-reported injection phobia and dental anxiety among individuals with tattoos and/or piercings. The Injection Phobia Scale-Anxiety (IPSA) short form and the Modified Dental Anxiety Scale (MDAS) questionnaires were applied.

Catastrophizing Has a Better Prediction for TMD Than Other Psychometric and Experimental Pain Variables.

Temporomandibular disorders (TMDs) are characterized by moderate to severe pain in the masticatory muscles and/or the temporomandibular joint (TMJ). The present study is a part of a multidisciplinary project, initiated by the Norwegian Ministry of Health. The main purpose of this study is to compare a cohort of TMD patients to healthy individuals regarding experimental pain, the degree of disability caused by living with pain and psychometric variables, and to investigate which of these variables is the best predictor for TMD patients.

Serum Analysis in Patients with Temporomandibular Disorders: A Controlled Cross-Sectional Study in Norway.

Temporomandibular disorder (TMD) is characterized by pain and dysfunction in the temporomandibular join (TMJ) and the masticatory apparatus. Associations with autoimmune diseases, inflammatory conditions, and nutrition deficiencies have been reported in previous studies of TMD patients. To evaluate essential proteins, hormones, electrolytes, and vitamins in serum from TMD patients, a standard blood sample analysis was performed in 60 TMD patients and 60 healthy controls matched for age and gender, retrieving 19 different analyses.

Temporomandibular Disorders Related to Stress and HPA-Axis Regulation.

Temporomandibular disorders (TMDs) are characterized by pain and dysfunction in the masticatory apparatus and the temporomandibular joint (TMJ). Previous trauma, stress symptoms, psychosocial impairment, and catastrophizing have been related to TMD. To assess if the hypothalamic-pituitary-adrenal (HPA) axis is upregulated in TMD patients, we performed a cross-sectional study with saliva from 44 TMD patients and 44 healthy sex- and age-matched controls for cortisol () and cortisone () with liquid chromatography-tandem mass spectrometry.
