Study Notes
- To minimise musculoskeletal problems, ergonomics in dentistry should be understood and clinically applied
Intended Learning Outcomes
- Ergonomics should be defined in relation to dentistry
- The main goals of ergonomic design should be explained
- The risk factors associated with musculoskeletal disorders should be discussed
- The core baseline principles for effective ergonomics in dentistry (including the use of dental mirrors) should be discussed
- How the principles of effective clinical positioning can be demonstrated
Ergonomics in Dentistry
- Ergonomics is the science of designing workspaces to meet the needs of workers, rather than the other way around
- In dentistry, ergonomics ensures dental practices support and promote healthy movement and proper posture for all staff
- The goal is to eliminate musculoskeletal pain that ends many dental careers prematurely. This also helps improve the experience for both staff and patients
Main Goals of Ergonomics
- Reduce overexertion injuries
- Minimise fatigue
- Eliminate unnecessary tasks, steps, and effort
- Offer more opportunities for job satisfaction, comfort, and fulfillment
Consequences of Poor Ergonomics
- Impact treatment outcomes
- Cause job-related accidents and injuries
- Lead to shorter careers
- Reduce mood and well-being
- Result in loss of earnings and increased medical spending
- Musculoskeletal pain is present in up to 81% of dental personnel
- 70% of dental students report lower back pain by their 3rd year
- Musculoskeletal pain and injury are common reasons for early retirement and income losses
Risk factors for Musculo-skeletal Disorders
- Poorly designed workspaces
- Vibrations from tools
- Static positioning
- Repetitive movements
- Excessive force
- Minute grasping
Elements of Ergonomics in Dentistry
- Dental Instruments
- Surgery Design
- Hand instruments
- Power-driven equipment
- Weight of equipment
- Lighting
- Magnification
- Patient posture
- Clinician posture
- Operator and patient chair position
Surgery Design
- There are many design features to consider for dental surgery
Lighting Considerations
- Dental overhead lights should have even distribution of light
- Lighting should be shadow-free and Accessible
- Operatory lights should be Moveable, allow for side angulation, and have adjustable intensity for materials manipulation
Operator & Patient Chair
- The operator chair should be mobile and glide, be stable, offer lumbar support, be adjustable for different body sizes, and provide patient access
Operator position
- All joints and limbs are in a neutral position by avoiding pressure or effort:
- Feet should be flat on the floor
- Knees should be bent at ~90 degrees
- Buttocks should be properly positioned in the chair
- Elbows should be close to the body and supported
- Shoulders should be relaxed
Patient Positioning
- Correct patient positioning is vital
- Patient's head should be even with the upper edge of the headrest
Dental Mirror
- The dental mirror is an extension of the operator
- Uses: Indirect vision, retraction, indirect illumination, and trans illumination
- Is an essential part of practice ergonomically
Clock Positions
- Clock positions exist based on whether the operator is left or right-handed
Sense Check
- Check, are you nervous, are you able to think, can you reach the patient and are you moving out of neutral. Are you a squirrel! And is the chair and patient head in the best possible position
Operator head can be moved to improve access and posture
- Posterior Sextants (Head away)
- Anterior
- Posterior Sextants (Head towards you)
Further considerations for right-handed dentists
- The right handed dentists positions may vary, according to the area they work in, these are;
- Right Handed Clinician
- Right Handed Clinician: Anterior
- Posterior Sextants (Head away)
- Posterior Sextants (Head towards you)
