“…Dental work activities can contribute to the development of musculoskeletal symptoms such as pain, tingling and stiffness of joints mainly in the upper body . High prevalence of pain in the neck, shoulder and lower back has been observed in dentists and it has consequently reduced their productivity and contributed to a premature retirement …”

“…It is known, that it is not so easy to apply ergonomic knowledge in clinical practice for dentists who are not used to work in ergonomic way. Ergonomics is a discipline which requires a profound and systematic approach, regular practical training and control [21][22][23]. Therefore the promotion of ergonomics in dentistry should be highly encouraged by universities, Lithuanian Association of Dental Ergonomics and all the organizers of postgraduate courses in Lithuania.…”

SummaryThe study objectives were to investigate the preference of Lithuanian dentists to work with or without an assistant and to identify the most significant predictors for the preference. As well, we aimed to explore the education of practicing dental assistants in Lithuania. The information was collected by a postal questionnaire survey which was carried out among all practicing general dental practitioners and dental specialists in Lithuania (n=2971). The final response rate was 67.6% corresponding to 2,008 respondents. The results show that most dentists in Lithuania always or sometimes work without an assistant. Each third dentist of those who work with an assistant employ non-certified dental assistant. This may be done on purpose due to financial reasons. Dentists should be educated how efficient, ergonomic practice with a qualified dental assistant can be; inclusion of contemporary four-handed practice subject in applicants resume could improve employment of certified dental assistants in the long term.

The aims of this study were to adapt the Job Factors Questionnaire to the field of dentistry, evaluate its psychometric properties, evaluate dental students' perceptions of work/study risk factors for musculoskeletal disorders, and determine the influence of gender and academic level on those perceptions. All 580 students enrolled in two Brazilian dental schools in 2015 were invited to participate in the study. A three-factor structure (Repetitiveness, Work Posture, and External Factors) was tested through confirmatory factor analysis. Convergent validity was estimated using the average variance extracted (AVE), discriminant validity was based on the correlational analysis of the factors, and reliability was assessed. A causal model was created using structural equation modeling to evaluate the influence of gender and academic level on students' perceptions. A total of 480 students completed the questionnaire for an 83% response rate. The responding students' average age was 21.6 years (SD=2.98), and 74.8% were women. Higher scores were observed on the Work Posture factor items. The refined model presented proper fit to the studied sample. Convergent validity was compromised only for External Factors (AVE=0.47), and discriminant validity was compromised for Work Posture and External Factors (r=0.69). Reliability was adequate. Academic level did not have a significant impact on the factors, but the women students exhibited greater perception. Overall, the adaptation resulted in a useful instrument for assessing perceptions of risk factors for musculoskeletal disorders. Gender was found to significantly influence all three factors, with women showing greater perception of the risk factors.
