Prevalence of Musculoskeletal Diseases of the Upper Extremity Among Dental Professionals in Germany

Abstract

Objective Although many findings on occupational musculoskeletal complaints are available from American and European dentists, the corresponding data from Germany are still scarce. Therefore, the aim of this study was to provide additional information on the prevalence of and risk factors for musculoskeletal disorders of the upper extremity, particularly the shoulder in this specific population. Methods A written survey was carried out among 600 dentists in the state of North Rhine-Westphalia, Germany. Questionnaire items included physical and psychosocial workload, general health, and the occurrence of musculoskeletal symptoms during the previous 12 months that led to sick leave and medical care according to a modified version of the Nordic Musculoskeletal Questionnaire (NMQ). Regression analysis was used to evaluate relevant risk factors for severe musculoskeletal disorders. Results A total of 229 dentists were participated in the study (response rate 38%). Overall, 92.6% of the participants had already suffered from musculoskeletal symptoms in at least one body region. Symptoms were mostly reported in the neck (65.1%) and in the shoulder (58.1%). Limitations in daily activities were experienced by 15.9% due to neck pain and by 15.4% due to shoulder pain. Medical care was sought by 23.7% because of neck pain and by 21.1% due to shoulder pain. Risk factors for symptoms in the upper extremity regions were gender (female), increased physical load, and numerous comorbidities. Conclusion There is a high prevalence of musculoskeletal disorders among dentists. Suitable interventions are therefore needed to prevent musculoskeletal diseases and pain among dental professionals, with particular attention to female dentists.

Clinical Findings Related to Musculoskeletal Disorders (MSDs) in a Group of Orthodontists

“…However, it is also likely that more experienced orthodontists have already adapted to work positions that avoid the presence of MSDs. 4 One study carried out in Germany 22 found that the years of work showed to increase the percentage of MSDs. This situation could be related with a greater workload because patients seek to be treated by a more experienced professional.…”

“…This situation was found in a German study where the stress level was a very important factor related with the presence of MSDs. 22 In this study, other variables that showed a positive correlation with the presence of MSDs were considered, such as the absence of several contracts and dissatisfaction with the job. However, due to the little literature and the type of study that was carried out, it was not possible to make accurate comparisons.…”

How Does the Use of an Intraoral Scanner Affect Muscle Fatigue? A Preliminary In Vivo Study

“…In the present study, various factors were controlled for, and only participants who had a high willingness to participate, were very cooperative, and had a high understanding of its purpose were included. In addition, it is difficult for participants recruited in the present study to represent the results of various age and sex groups [ 33 ]. With increasing age, musculoskeletal disorders may increase, which may affect muscle fatigue and activation during certain activities.…”
