Self-reported musculoskeletal pain among dentists in Visakhapatnam: A 12-month prevalence study

Of the occupational hazards experienced by dental professional worldwide, work-related musculoskeletal disorders (WRMSDs) are quite common. Research in the past has recognized that musculoskeletal disorders in dentistry contribute considerably to sick leave, reduced productivity, and dentist attrition. Considering the magnitude of these disorders, an attempt has been made to determine the prevalence and associated factors of various WRMSD.

The aim of this study was to investigate the prevalence of self-reported, work-related musculoskeletal problems regarding the perception of pain, over the preceding 12 months and also to identify associated factors which might influence pain among dentists.

A self-administered questionnaire was personally handed over to a select sample of practicing dentists in Visakhapatnam, Andhra Pradesh. The survey was performed using the Nordic Musculoskeletal Questionnaire.

This study revealed musculoskeletal pain with a frequency of 56% in the neck, 39% in the hand, 32% in the lower back, and 18% in the shoulder regions. Chi-square test showed a significant association between pain in the neck and gender, age, height, and weight (P < 0.05). Pain in lower back was associated with gender, body mass index (BMI), height, and experience (P < 0.05). Pain in the hand was only related to the experience of the dentist (P < 0.05).

Within the limits of the study, the prevalence of WRMSD among dentists in Visakhapatnam, especially involving the neck, hand, lower back, and shoulders, is high. Gender, age, height, and weight, BMI and experience were found to be related with musculoskeletal pain.
