Background and Aims: Musculoskeletal disorders (MSDs) are among the most common occupational health problems faced by dentists. Given their impact on dentists’ health and performance, the present study aimed to investigate the prevalence of MSDs among general and specialist dentists practicing in Babol, Iran.
Materials and Methods: In this cross-sectional study, the standardized Nordic questionnaire, consisting of general and specific sections, was distributed in person among dentists practicing in Babol, based on data obtained from the local Medical Council. Distribution was carried out after a telephone invitation and confirmation of willingness to participate. The questionnaire included items regarding pain and discomfort in different body regions such as the neck, shoulders, and lower back. The frequency of participants with MSDs was assessed based on gender, right/left handedness, specialty, playing sports, and participating in a specific sport. The mean age, weight, height, body mass index, weekly working hours, and work experience of dentists with and without MSDs were also compared. Data were analyzed using SPSS software version 22, employing independent t-tests, Chi-square tests, and Fisher’s exact test, with a significance level set at 0.05.
Results: Of the 182 dentists approached, 17 declined participation and 5 met the exclusion criteria. A total of 160 dentists (mean work experience: 15.65 ±9.26 years) were included in the study; of these, 100 (62.5%) were male, 95 (59.4%) were general practitioners, and 65 (40.6%) were specialists. The overall prevalence of MSDs in this population was reported to be 90%. The most commonly affected region was the neck (76.4%), while the least affected was the ankle (3%). A statistically significant association was found between engaging in a specific type of regular physical activity and a reduced incidence of MSDs (P<0.001). No significant associations were observed with other variables such as gender, handedness, specialty, or field of specialization (P>0.05). Furthermore, no significant differences were found in the mean height, weight, body mass index, weekly working hours, or years of experience between dentists with and without MSDs (P>0.05).
Conclusion: Musculoskeletal disorders are highly prevalent among dentists in Babol. Given this high prevalence, the development and implementation of educational programs on ergonomics, along with recommendations for targeted physical activity appear to be essential.
