Prevalence of Painful Temporomandibular Disorder Symptoms Among Professional and Student Musicians: An Online Survey

BACKGROUND

Within the fields of medicine and music, increasing attention is given to evidence indicating music performance being an occupational risk factor for temporo-mandibular disorders (TMD).

OBJECTIVES

Assessment of self-reported painful TMD symptoms among student and professional musicians.

METHODS

Using Survey Monkey software, the German version of the 'TMD-Pain-Screener' was distributed electronically to professional and student musicians in Europe. Supplementary questions addressed age, gender, daily playtime, instrument type and type of professional practice. Results are presented as median [interquartile range].

RESULTS

The TMD-pain-screener was completed by 492 participants. Among them, 96 (19.5%) reported painful TMD (Pain_pos) and 396 did not experience pain (80.5%, Pain_neg). Pain_pos participants were significantly younger (Pain_pos: 34 years [26; 46], Pain_neg: 44 years [30; 56], p = 0.0003), had less work experience (Pain_pos: 15.5 years [6; 25], Pain_neg: 20 years [10; 32], p = 0.009), had fewer performances/year (Pain_pos: 20/year [10; 45], Pain_neg: 30/year [12; 53.5], p = 0.03) and were predominantly female (OR = 3.22 [1.87, 5.74], p < 0.0001). Comparisons among music performance types revealed no statistical significance in the overall test (p = 0.13), although 'keyboard' (OR = 2.99 [0.58, 30.12]), 'upper string' (OR = 2.31 [0.43, 23.63]) and 'singer' (OR = 2.14 [0.44, 20.75]) stood out compared to the reference group 'lower string' (OR 1.00). Organ players formed the largest group and showed a comparatively low prevalence of Pain_pos (16%), compared to other keyboard instruments (Pain_pos 30.2%).

CONCLUSIONS

Prevalence of TMD pain was highest among young inexperienced female musicians. Playing keyboard instruments (other than organ) or upper strings instruments were frequently associated with painful TMD screening. An improved understanding of causes, implementation of preventive measures, professional guidance and a biopsychosocial health care perspective may decrease this occupational risk while maintaining the health benefits of music.

Headache Because of Problems with Teeth, Mouth, Jaws, or Dentures in Chronic Temporomandibular Disorder Patients: A Case–Control Study

This study aimed to characterize self-reported headaches because of problems with the teeth, mouth, jaws, or dentures (HATMJD) in chronic patients with temporomandibular disorders (TMDs) in order to compare their results with those of TMD patients without such headaches and to investigate the associations of HATMJD with depression, anxiety, physical symptoms, oral behaviors, and sleep quality. We conducted a case–control study on consecutive chronic TMD patients referred to the University Medical Center of Ljubljana, Slovenia. A self-reported HATMJD was extracted from item #12 in the 49-item version of the Oral Health Impact Profile questionnaire. Axis II instruments of the Diagnostic Criteria for TMD (i.e., for screening of depression, anxiety, specific comorbid functional disorders, and oral behaviors) and the Pittsburgh Sleep Quality Index were used in this study. In total, 177 TMD patients (77.4% women; mean age: 36.3 years) participated in this study; 109 (61.6%) patients were classified as TMD patients with HATMJD. TMD patients with at least mild depressive and anxiety symptoms, with at least low somatic symptom severity, and a high number of parafunctional behaviors had more HATMJD. Parafunctional behavior and sleep quality were the most prominent predictive factors of the occurrence of HATMJD. TMD patients with HATMJD have more psychosocial dysfunction, a higher frequency of oral behaviors, and poorer sleep quality than TMD patients without such headaches.
