Study Notes
Ergonomics in Dentistry
- Ergonomics is the science of adapting workplaces to meet the needs of workers.
- In dentistry, this means creating a practice environment that supports and promotes healthy movement and good posture.
- Focus is on eliminating musculoskeletal pain and enabling staff to provide better care.
Main Goals Of Ergonomics
- Reduce overexertion injury
- Minimize fatigue
- Eliminate unnecessary tasks and effort
- Promote job satisfaction, comfort, and fulfillment
Consequences of Poor Ergonomics
- Loss of earnings
- Increased money spent on healthcare and pain management
- Impacts on treatment outcomes
- Poor ergonomics can impact mood and well-being
- Increased risk of accidents and injuries
- Shortened career span
Why We Should Care About Ergonomics
- 70% of dental students reported lower back pain by their third year of studies
- Musculoskeletal disorders (MSDs) are present in up to 81% of dental personnel.
- MSDs are a common reason for early retirement
- MSDs can impact income and performance
Risk Factors For Musculoskeletal Disorders
- Poorly designed tools and workstations
- Static positioning
- Repetitive movements
- Excessive force
- Vibrations
- Minute grasping
Ergonomics in Dentistry
- Focuses on equipment, instruments, the workstation, and operator and patient positioning.
Workstation Considerations
- Adequate counter space
- Easy access to instruments and supplies
- Proper lighting and magnification systems
Surgery Design
- Proper layout for efficient workflow
- Clear workspace for instruments and tools
- Surfaces that are easy to clean and disinfect
Lighting
- Should be even in distribution
- Shadow-free
- Accessible
- Moveable
- Allow for side angulation
- Intensity adjustable to suit material manipulation
Dental Overhead Lights
- Should be even in distribution
- Shadow-free
- Accessible
- Moveable
- Allow for side angulation
- Intensity adjustable to suit material manipulation
Operator and Patient Chair
- Operator chairs should be mobile, have glide ability, and be stable.
- They should offer lumbar support, adjustable height, and be able to accommodate different body sizes.
- Saddle seats or seats with backs are recommended.
Patient Chair
- Should be comfortable and provide access to appropriate treatment areas
- Include a stable base with an adjustable headrest
- Offer support for the head, torso, and feet.
Operator Position
- All joints and limbs should be in a neutral position:
- Feet flat on the floor
- Knees at a 90-degree angle
- Buttocks touching the chair back
- Elbows at a 90-degree angle
- Shoulders relaxed and not hunched
Finding the Correct Patient Height:
- Ensure adequate access while maintaining a neutral posture
- Positioning the patients head ensures a clear view of the treatment area
Clock Positions
- The clock position system is used for describing the working positions of the hands during dental procedures.
- A 12 o'clock position indicates the most comfortable neutral position for all procedures.
- Other positions should be reached without compromise to neutral posture
The Dental Mirror
- The mirror is a vital tool in dentistry.
- It provides indirect vision and allows for retraction of the tongue and cheek.
- It can be used for indirect illumination and transillumination.
- Mirror selection should consider size and magnification needs.
Mirror Use
- The dentist should practice mirror use to ensure smooth and efficient movements.
- It's essential for clear vision and performing manipulations accurately without compromising posture.
Mirror Fun
- The text recommends using "join the dots" diagrams for practicing mirror skills.
Sense Check
- Before starting any procedure, check the position of your body and the patient's head.
- Ensure:
- Comfortable and neutral posture
- Unobstructed vision
- Ability to perform the procedure without compromise
- Proper clock position for maximum efficiency.
