The questionnaire consisted of 34 items divided into five sections; socio-demographic, job characteristics, knowledge of dental ergonomics, attitude towards dental ergonomics and the practice of dentists regarding dental ergonomics. Bivariate analysis was conducted using Pearson Chi-square Test. Result: 76.2% dentists have poor dental ergonomics practice. There is a significant relationship (p-value < 0.05) between the practice of dental ergonomics and age group, years of practical experience and level of knowledge. Conclusion: Most Indonesian dentists (76.2%) still lack of dental ergonomics practice. Age, duration of work experience and ergonomic dental practice knowledge are significantly correlated.
