OUTLINE
In dentistry, occupational health hazards are common and increasing.
Musculoskeletal disorders (MSDs) which is one of the occupational health hazards are significant and cause a serious damage.
INTRODUCTION
The World Health Organization (WHO) defines it as being disorders affecting the muscles, tendons, peripheral nerves or vascular system not directly resulting from an acute or instantaneous event.
WHO lists MSDs as the most common problem that affects workers, especially dental health care personnel who are exposed daily to a work environment.
INTRODUCTION (2)
What is the prevalence and risk factors of MSDs
among dental practitioners ?
RESEARCH QUESTION

The results show that the prevalence of MSDs symptoms among
dental practitioners in Bafoussam and Douala is high (78.75%).
The most aggravating factor was the position with a large score of
73.12%.
Pain,discomfort and fatigue were the commonly symptoms
reported. The most common body areas affected were the neck
(39.68%), the low back (44.44%), the shoulders (4.76%), the wrist
(1.59%), the lower leg (1.59%), and the feet (7.94%).
CONCLUSION
Female dentists had a significantly higher frequency of pain, discomfort and
fatigue than the male counterparts.
Ergonomics knowledge are well assimilated by the majority of dental workers but
just a few minority apply it during their working time and that is why the
prevalence of MSDs is too high among dentals professionals .
This increase lead to pain,stress,fatigue and has a serious impact on the finances of
those suffering from these symptoms. They spend a lot of money in the
management of their symptoms.
To conclude work-related Musculo-skeletal disorders represent a high significant
burden for dental profession.
CONCLUSION (2)
Ministry of the Public Health to bend over this situation which is not negligible as the result showed and put in place serious measures to palliate to it such as: policies, safety control and seminars based on preventive measures like Dental Ergonomics for all dental workers .
RECOMMENDATIONS
The Ministry of the High Education is also called to implement programs concerning the preventives measures as Dental Ergonomics in the dental academicals programs. These programs will be applied and coordinated in Saint Louis University Institute for the Dental Therapists students and also in other dental schools in Cameroon in the aim to familiarize them with those precautions.
RECOMMENDATIONS (2)
