Fatores ergonômicos críticos de mochos odontológicos e sua relação com a produtividade e satisfação de cirurgiões dentistas

The purpose of the ergonomics is to generate adequate working conditions, by the correct use of equipment and appropriate anatomic positions. Ergonomics has become essential in the dentist's life while in the dental practice. The misuse of equipment in performing tasks or the wrong choice of equipment can initiate various problems like back pain, bursitis, repetitive strain injury (RSI), limitation of movement, and stress. Using a survey that was implemented with professional dentists linked to Paulista Association of Dental Surgeons (APCD) and graduate students at the Universidade Estadual Paulista (UNESP) in the São José dos Campos (SP) region, this study intends to propose an adequate research instrument to identify ergonomic critical factors of dental stools and their relation to productivity and satisfaction of dentists. The survey was developed with Google Docs Forms tool and was designed by analysis of other studies, existing surveys and other papers in this area. Relevant content were discussed and developed questions about the stool used by dentists in their activities, the occurrence of any problems arising from the exercise of their profession and the views of respondents about the influence of using the dental stool in these cited problems as well as their productivity. Due to obstacles encountered during the project, particularly bureaucratic issues, the survey cannot be implemented as needed, resulting in a test with reduced number of answers. The users' opinion varies according to the stool used, bringing some difficulty to generalizing the answers, but if treated properly, it is possible to obtain relevant conclusions about the main aspects perceived by users in relation to the stool and the needs pointed as most important
