Gender Differences in Clinical Characteristics of Korean Temporomandibular Disorder Patients

Abstract

The aims of this study were to investigate the gender differences in signs and symptoms of Korean Temporomandibular Disorder (TMD) patients based on Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) and psychosocial characteristics. A total of 1052 patients with TMD were evaluated with a questionnaire for medical history, clinical symptoms, and contributing factors, clinical examination based on RDC/TMD, and radiographic examination. RDC/TMD axis II and Symptom Checklist-90-Revision (SCL-90-R) were administered to evaluate pain-related disability level and psychological status of patients. The prevalence of TMD was higher in women than men, and the women were older than the men. The women showed higher prevalence of myogenous pain, mixed pain, disc displacement without reduction, osteoarthritis, headache, subjective insomnia, pain intensity, number of positive muscle palpation, and the high disability group in the grade chronic pain scale. Gender was associated with the number of positive muscle palpation and maximum mouth opening. Pain intensity was not associated with gender, but with number of systemic comorbidities. Subjective symptoms, and clinical and psychological characteristics of patients with TMD showed gender differences. To achieve understanding of patient and increase of success rate of treatment of TMD, gender should be considered in patient evaluations and treatment approaches.

“…It was also mentioned that there was a decreasing distribution of the disease with age, which could indicate the limiting feature of the disease. The present study highlighted the presence of a higher female predilection, which is similar to the studies reported by Bagis et al, Ferreira et al, and Jo et al 13 14 15 Furthermore, the average age of the population is 41 ± 16 years, with the minimum age being 19 and the maximum being 68, similar to a study by Ferreira et al 14…”

Comparative Analysis of Salivary Cortisol in Young Adult Patients with Temporomandibular Disorders

“…It primarily affects teens and 20s, and the prevalence rises with age, with women being more affected than men [1,2]. A recent domestic study also found a rapid increase in the number of patients in their 20s, but the cause is unknown [2]. Therefore, in this study, while there are numerous causes of TMDs, salivary cortisol was measured for the group in their 20s to assess the relationship with stress (Table 1).…”

“…TMDs cause temporomandibular joint and masticatory muscle pain and dysfunction. It primarily affects teens and 20s, and the prevalence rises with age, with women being more affected than men [1,2]. A recent domestic study also found a rapid increase in the number of patients in their 20s, but the cause is unknown [2].…”

“…Occlusion, trauma, emotional stress, deep pain input, and parafunctional activity are known as the primary causes [1]. In recent years, the prevalence of TMDs has been steadily increasing, and the prevalence is especially high among young adults [1,2]. It is thought that stress due to the complexity of modern social life is the major cause of such a situation, but it has not been proven.…”

“…Moreover, a meta-analysis before the pandemic by Bueno et al [ 53 ] reported a higher prevalence and greater tendency for females to have TMD than males. In 2021, another study [ 54 ] carried out in South Korea revealed more TMD symptoms in females, who presented a higher prevalence of pain and muscle palpitations compared to males.…”
