Summary
Dentists experience higher muscle activity when sitting versus standing. Alternating between sitting and standing postures can reduce fatigue and prevent injuries in dental professionals.
Area of Science:
- Occupational health
- Ergonomics
- Dental medicine
Background:
- Proper working posture is crucial for dental professionals' health and efficiency.
- Poor posture in dentistry can lead to increased fatigue, reduced productivity, and potential injuries.
Purpose of the Study:
- To analyze and quantify the posture positions adopted by dentists during their work.
- To compare muscle activity and body segment positions between sitting and standing postures in dental interventions.
Main Methods:
- Electromyography (EMG) was used to measure muscle activity.
- Body segment positions, specifically back inclination, were recorded.
- Data were collected during standard dental procedures for both sitting and standing postures.
Main Results:
- Forward and lateral flexion of the back, less than 20 degrees, was most common in both sitting and standing.
- Muscle activity (EMG amplitude) was significantly higher in the sitting posture compared to standing for all measured muscle groups.
- Specific muscles like splenius capitis and mastoid showed significant differences in activity between sitting and standing.
Conclusions:
- Combining sitting and standing postures during dental work may mitigate risks associated with increased fatigue.
- Alternating occupational postures can help prevent work-related injuries in dentists.
