An assessment of musculoskeletal disorders and physical activity levels in dentists: A cross-sectional study.

Abstract

Background: Dentistry is a physically and mentally demanding profession that involves long periods of muscle imbalance and asymmetrical postures when performing delicate procedures. This can lead to a high incidence of work-related diseases. However, physical activity may prevent or minimize the incidence of musculoskeletal discomfort and pain.

Objective: The present study aimed to determine the association between musculoskeletal disorders and physical activity levels in dentists practicing in Turkey.

Methods: This cross-sectional study was conducted between March and June 2023 with dentists from Turkey actively practicing dentistry. The short form of the International Physical Activity Questionnaire was used to determine dentists' physical activity levels, and the Extended Nordic Musculoskeletal Questionnaire was used to assess musculoskeletal disorders. IBM SPSS 20 software was used for statistical analysis. Data were presented as mean, standard deviation, median, minimum, maximum, percentage, and number. Chi-square, Mann-Whitney U, One-Sample Chi-Square tests, and an ordinal logistic regression test were used. The statistical significance level was taken as p <  0.05.

Results: A total of 116 dentists (63 females 53 males) between the ages of 24 and 60 (36.37±7.32) were included in the study. Forty-eight participants had a low level of physical activity, 56 had a moderate level of physical activity (MLPA), and 12 had a high level of physical activity (HLPA). There was no significant difference between the gender (p = 0.224) and age (p = 0.469) of the participants and levels of physical activity. Musculoskeletal discomfort was reported by 93.1% (n = 108) of the participants in one or more body parts (p <  0.001) and 55.6% (n = 60) of them were female. The number of dentists with neck (p <  0.001) and shoulder (p = 0.05) problems was significantly higher. There was no significant effect of gender (p > 0.05) on musculoskeletal conditions. However, the relationship between musculoskeletal conditions and physical activity levels was inconsistent. The HLPA group reported the lowest discomfort for all body parts, except the elbows and knees (p <  0.05). The MLPA group reported higher discomfort in the neck, shoulder, upper back, wrists/hands, lower back, and knees. The group with the lowest physical activity exhibited the highest discomfort in the elbow and ankle/feet regions.

Conclusion: This study found that the prevalence of musculoskeletal disorders was high among dentists, many of whom reported either low or moderate physical activity levels. The results of this study may enhance dentists' understanding of work-related musculoskeletal diseases and promote their participation in physical activities.
