Dental assistants in maintaining dental and
oral health are required to work quickly and precisely
because they are very responsible for activities before,
during and after dental treatment takes place,
musculoskeletal disorders are disorders that can cause
muscles to not function properly due to activities that are
too heavy which can cause posture unnatural body. One
strategy to overcome this problem is through the
ergonomic model of the dental chair side assistant
"Edition" this model consists of working positions and
work place stretching. The purpose of the study was to
analyze the effectiveness of the ergonomic model of the
Dental Chair Side Assistant "Edition" on the risk of
working posture in dental and oral therapists "Edition".
The method used is a quasi- experimental pre-test and
post-test with control group design. Sampling using the
Lemeshow formula. The research sample was divided into
2 groups, namely the intervention group and the control
group which consisted of 32 people, based on the inclusion
criteria. This study used a questionnaire instrument and
an observation sheet. Statistical test using Intraclass
correlation coefficient, Mann Whitney, and Wilcoxon.
The results obtained are the ergonomic model of the chair
side assistant "Edition" effectively reduces the risk of
work posture (p = 0.000) so it can be concluded that the
ergonomic model in the chair side assistant "Edition" is
effective as a model used in reducing complaints of
musculoskeletal disorders, namely the risk of work
posture in dental and oral therapist.Keywords:
