Wrong postural hygiene and ergonomics in dental students of the University of Valencia (Spain) (part I)

subject

description

Introduction Failure to adopt a correct working posture can lead to occupational diseases. Objectives Evaluate knowledge in relation to ergonomics about BHOP concept and its application to routine clinical practice amongst undergraduate and postgraduate dental students in the University of Valencia (Valencia, Spain). Material and methods A study based on interviews of undergraduate and postgraduate dental students in the University of Valencia (Valencia, Spain) was carried out. The information from a total of 336 interviews was used for the statistical analysis, differentiating according to gender and academic year: knowledge of ergonomics, pain prevalence and antecedents, assessment of the possible necessity for improved training in ergonomics, and evaluation of postural hygiene. Results Only 28.6% of the students were found to sit correctly in the dentist chair. Furthermore, in the opinion of the students, very few subjects during the career afforded adequate teaching in relation to ergonomics and working posture. The analysis of postural hygiene showed great variability. There were no significant differences in posture between males and females, although some incorrect postures appeared to be associated with the academic year (P<.05). However, no significant improvements in postural hygiene were noted on progressing from one academic year to the next. Conclusions The students in our study were not familiar with the principles of ergonomics and did not sit correctly in the dentist chair. Improved training in this field is required in dental school.
