Dental Ergonomics Part 1

Course Description

Dental Ergonomics Part 1.mp4Musculoskeletal pain develops when clinicians practice dentistry with less than optimal postures; twisting and bending the neck and torso, compressing the spine, using muscles and joints inefficiently.   This is the reason why there is such a high incidence of work-related chronic pain in the dental profession.

Ignorance prevails in the profession as the education system in dental colleges misses out on one of the most important keys to success in promoting healthy dental career i.e. dental ergonomics enabling the dentist to work comfortably, stress-free in a painless & healthy way.

How the operator sits on a stool and bends over the chair is as important as the stool and chair design. The way instruments are held is as important as the design of the instrument. Hence awareness on Dental Ergonomics is the need of the hour.

    Practicing Dentistry Pain Free
    1. Dental Ergonomics

      This course unites dental operatory to the dentist and allows both to work in coordination with each other thereby eliminating pain that a dentist is prone to due to static forward bending posture & poor operatory layout.

      •    Musculoskeletal disorders amongst Dental professionals.
      •    How poor posture in Dentistry lead to Musculoskeletal disorders?
      •    Why is Dental Ergonomics important?
      •    Is your Dental Delivery system delivering Pain?
      •    How to prevent Work-related Pain in Dentistry?
      •    Stretching your way Out of Pain with correct posture & chairside stretches.
      •    Exercises for Dental Professionals.
      •    Ergonomizing workstation with correct Operatory layout & Equipment selection.


      •    Practice dentistry pain-free
      •    Maintaining Neutral working posture
      •    Reduce potential for overexertion injury
      •    Train dentists to perform chairside exercises in between appointments
      •    Arranging dental stool and dental chair optimally
      •    Ergonomic Instrument & Equipment selection 

      Learning Objectives

      Upon completion of this course, the dental professional should be able to:

        • Understand the impact of physiological stress on one’s well-being.
        • Understand how ergonomics is vital in all aspects of dentistry.
        • Identify characteristics of equipment that will promote good ergonomics.
        • Identify risks that lead to musculoskeletal pain.
        • Identify the predominant areas of pain in the dental practitioner and how often they occur.
        • Identify ways to modify the dental team’s work practice.
        • Apply the concept of cognitive awareness to prevent musculoskeletal dysfunction.
        • Learn how nutrition is important in preventing muscle pain.
        • Recognize the benefits of physical activities in reducing musculoskeletal disorders.

    Chapter 1 : Musculoskeletal Pain & Disorders - An Introduction
    1. This chapter deals with how dentists start experiencing pains in musculoskeletal structure. 60%-90% Dentists suffer from work-related musculoskeletal disorders(WMSD's) which affect neck, shoulders, back and upper extremities.Prevention of WMSD's is becoming crucial and requires the identification and modification of risk factors. Individual characteristics of the worker--such as gender, age, stature, physical condition, strength, etc.--may contribute to the occurrence of these musculoskeletal disorders.  Causes of MSD’s among dentists are:

      •          Repetitive motions (e.g., scaling, polishing)
      •          Excessive Force (e.g. tooth extraction)
      •          Static neck, back, and shoulder postures
      •          Grasping small instruments for prolonged periods
      •          Prolonged use of vibrating hand tools


      This chapter is an introduction to various musculoskeletal disorders & their prevalence among dental professionals.

    Chapter 2 : Cumulative Trauma Disorder: Risk Factors
    1. Accumulation of pain due to insufficient breaks in between appointments lead to Cumulative trauma disorders (CTDs). In this chapter we will discuss what are the causes that lead to CTD's, its warning signs and symptoms. Cumulative trauma disorders are health disorders arising from repeated bio-mechanical stress to the hands, wrist, elbows, shoulders, neck and back.

    Chapter 3 : What's causing your Pain?
    1. This chapter incorporates various static postures in which dentists work and accounts for the risk factors leading to trauma in dentistry. Further, in this section there is detailed description of muscle ischemia, muscle imbalances and trigger points leading to CTD's  among dentists. One of the biggest challenges in dentistry are the prolonged static postures that are forced to sustain for long period of time chairside.

    Chapter 4 : Classification of Motion
    1. Amount of motion a dentist does in the operatory to reach for the instruments or into the oral cavity defines ergonomic working styles. Through classifying these degree of motions one can discover which motions should be avoided. Hence, in this following chapter we will be discussing in detail the classification of motions to deliver patient care and stating which motions should be prohibited in order to maintain balanced seated posture.  

    Chapter 5 : Posture, Positioning & Periodic Stretching (3P's to Fitness)
    1. A "good" posture provides the dentist more working energy, a reduced stress level, increased comfort, lack of pain and muscular tension and a lower risk for therapeutic errors.

      Positioning not only the dentist but the operatory to fit the dentist’s need and posture throughout the treatment provides with comfortable stress free working environment.

      Incorporating Periodic stretching chairside and outside the operatory maintains normal range of motion and improving flexibility.

      Thus, in this chapter optimal seating posture, positioning of operatory and easy chairside 15-20 seconds stretches are described.

    Chapter 6: Forward Bending results in Pain in Back
    1. Introduction to what are the factors that cause pain in back of a working dental professional, description of various seating postures that cause muscle imbalances and keys to prevention of low back pains. In addition to, this chapter also describes how different seating postures affect the spine and keys to obtain a balanced seated posture in order to prevent low back pains. 

    Chapter 7: Hand Pain due to Over flexion of Wrist
    1. This chapter deals with describing what causes pain in hand with continuous working,  amount of flexion of wrist for optimal working, type of instruments that should be used while operating and working postures. Moreover, it provides with discussion of Carpal Tunnel Syndrome which is most commonly associated with pain in hand for dentists. It explains how an over flexed wrist causes increased pressure and results in immense  pain in wrist and fingers.

    Chapter 8: Practicing Dentistry Shouldn't be Pain in Neck and Shoulders
    1. This chapter describes various disorders leading from pain in neck and shoulders, working postures that lead to increase in stress in neck and shoulder muscles causing trigger points and then addressing strategies to prevent and reduce neck and shoulder pains.

    Chapter 9: Exercises For Dental Professionals
    1. Certain specific exercises for dentists that should be performed in order to relax muscles which are tightened due to working conditions in the operatory. Practicing these specific exercises decreases muscle pains and enables dentists to work pain free.

      In this chapter we will discuss short and simple exercises along with yoga which will prove beneficial against the chronic pains which developed due to years of dysfunctional postures and movements in dentistry.

      These exercises involve use of Swiss ball and a S-shaped self massage tool that helps in relieving trigger points and preventing as well as minimizing pain. If these exercises are done as explained in chapter, protection against symptoms of pain caused by static postural loads can be achieved.
