Full title: Clinical Manifestations, Imaging Features, and Pathogenic/Prognostic Risk Factors for Temporomandibular Disorders (TMD): A Case-Control Study Based on Psychogenic Factors of Patients

Abstract

Objective. To survey the clinical manifestations and imaging features of temporomandibular disorders (TMD) and analyze the risk factors for pathogenesis/prognosis through a case-control study based on psychogenic factors of patients.

Methods. According to the inclusion criteria, 200 adult patients were randomly enrolled from the maxillofacial department of our hospital from January 2020 to May 2021, including 100 patients with TMD as the study group and 100 healthy patients as the control group. The study group can be assigned into four subgroups according to their clinical manifestations: (1) articular area or/and masticatory muscle pain group, (2) mandibular movement abnormality group, (3) joint murmur group, and (4) two or more symptom groups. Based on the study of psychogenic factors of patients, the clinical manifestations and imaging features of TMD were determined, and the risk factors for pathogenesis/prognosis were analyzed.

Results. The distribution of psychological status in the TMD group was higher than that in the control group (). The distribution of anxiety, depression, and somatic symptoms in the TMD group was significantly different from that in the control group (). Anxiety, depression, and somatic symptoms were the risk factors for TMD. Compared with the control group, the incidence of abnormal MRI images in patients with temporomandibular disorders was significantly different (). There were significant differences in psychological status (anxiety, depression, and somatic symptoms) among the three groups (). Anxiety, depression, and somatic symptoms were the risk factors for abnormal mandibular movement and joint tremor and murmur (). Somatic symptoms were the risk factors for various clinical symptoms of TMD (). Depression was the risk factor for pain ().

Conclusion. In patients with TMD, MRI can early identify disc abnormalities and other related imaging features, which is helpful for more comprehensive clinical evaluation and treatment of TMD patients. There exhibits no significant difference in psychological status (anxiety, depression, and somatic symptoms) of patients with different clinical symptoms, and abnormal psychological status may be one of the risk factors leading to different clinical symptoms and development of different types of TMD patients.

As long as you have a button and soup ingredients, you can make a button soup. But no matter what ingredients you use, it's always a button soup if you add a button to it.

It's hard to put in context the absurdity of it being normal in medical research to observe that symptoms are associated with symptoms but also if you ask questions about symptoms but attribute them to thinking, it's all about thinking. Literally taking the outcome and reattributing it as the cause. Every. Single. Time.

Actually it's even more amazing how much mental gymnastics these people do and yet they can't seem to ever improve their condition.

 

And how was psychological status assessed?
Is this another use of scales which are pretty useless for pain / chronic illness ?

 

"The patients were examined by general data, GAD-7, PHQ-9, and PHQ-15 self-rating psychological scale, and clinical and imaging examination of the temporomandibular joint (CBCT or MRI)."

Links to the scales, all of which could easily psychologise chronic illness.

PHQ-9
