Bottom Line: The musculoskeletal disorders are probable prolonged in working hours in static positions, incorrect work postures, implying more force and even tools and instruments.Therefore, students who are aware of ergonomic principals of their own profession would be able to maintain their health through activities and lifelong.Key words:Posture, dentistry, students, musculoskeletal pain.

ABSTRACT

Background: Work-related musculoskeletal disorders commonly experienced by dental professionals are one of the main occupational health problem affecting their health and well-being.This study was conducted to evaluate ergonomic factors and profession-related postures and also investigate relationship between demographic factors and work condition with pain in dental students.

Material and methods: 60 freshman and sophomore dentistry students were randomly chosen as the subjects of control group, and 60 of 5th and 6th-year students were selected as the members of exposure group. Data related to the subjects such as sex, doing exercise, severity of musculoskeletal pain were obtained through questionnaire. Students' postures were directly observed while treating patients and they were scored by REBA method. Data were analyzed by SPSS software using Man-Whitney, Kruskal-Wallis, Spearman and Kendall correlation tests.

Results: 80.8% of the subjects were not aware of the correct ergonomic postures for dental procedures. Severity of musculoskeletal pain in the exposure group (15.9± 4.2) was significantly higher than the control group (10.5 ±3.2), (p <0.001). Risk of the most subjects (84%) was at the medium level. Students who were more involved in clinical activities experienced more muscular pains.

Conclusions: The musculoskeletal disorders are probable prolonged in working hours in static positions, incorrect work postures, implying more force and even tools and instruments. Therefore, students who are aware of ergonomic principals of their own profession would be able to maintain their health through activities and lifelong. Key words:Posture, dentistry, students, musculoskeletal pain.

Figure 2: REBA mean for the students of the control and exposure groups with regard to clinical activities.

Mentions: Figure 2 reveals REBA average based on clinical activities. The mean REBA score at Endodontic, surgery, fixed prosthesis and reconstructive dentistry was 6.6±2.1, 6.4±2.8, 5.6±1.7 and 4.8±2.3, respectively. The Endodontic department owns the highest REBA score, while the lowest score accounts for the reconstructive department. No significant relationship was detected between REBA scores and the type of clinical activities (P= 0.281), gender (P=0.263), duration of time spent on working with computer (P=0.999), experiencing musculoskeletal pain (P=0.158), knowledge about proper ergonomic positions (P=0.642), stretching between dental treatment activities (P=0.456) and seat adjustment before starting a clinical treatment (P=0.063).
