Effectiveness of Computer-Aided Versus Clinical Simulation Sessions on Knowledge, Attitude and Practice of Ergonomics

Study Overview
=================
Brief Summary
-----------------
A healthy dentist is one of the most important components of a successful dental practice. It is estimated that more than half of practitioners have some kind of painful work-related musculoskeletal disorders. It was reported that 80% of dental students were not aware of ergonomic posture during dental procedures. It is believed that dental students with knowledge of ergonomic principals would be able to maintain their health. Some studies demonstrated that the frequency and severity of WMSDs might decrease by training the dentists on ergonomic principles.

Detailed Description
-----------------
This study will be carried out on dental interns in Department of Pediatric Dentistry and Dental Public Health, in Faculty of Dentistry-Cairo University. The procedures will be carried out by postgraduate student Nourhan Saad Mohamed who has M.D.S. (2018) - Cairo University- Egypt, and works as Assistant Lecturer in Future University in Egypt. The procedures will be done without assistant at a lecture room and outpatient clinic of Pediatric Dentistry in Cairo University. At baseline, evaluation of knowledge, attitude and practice (KAP) on ergonomics in dentistry will be do e through a self-structured questionnaire. Afterwards, the participants will be split into two groups. One group will recieve training on ergonomic principles through clinical simulation session, while the other group will recieve training through Computer-aided sessions. KAP will be re-evaluated after the training sessions to evaluate the change in KAP about ergonomics.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| KAP questionnaire on ergonomics in dentistry | At baseline, assessment of the knowledge, attitude and practice of dental interns regarding ergonomics in Dentistry will be done before the educational module assigned to each group. The questionnaire will include 25 multiple choice questions, each question will score 4 with the total questionnaire out of 100. The questionnaire that will score 75 or less will considered as failed. | 1 questionnaire for 15 minutes before the learning modules | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in knowledge, attitude & practice of ergonomics after interactive learning about ergonomics in dentistry through computer-aided sessions on ergonomic principles. | Assessment of the knowledge, attitude and practice of dental interns regarding ergonomics in Dentistry will be done after the educational module assigned to the group. The questionnaire will include 25 multiple choice questions, each question will score 4 with the total questionnaire out of 100. The questionnaire that will score 75 or less will considered as failed. | 1 questionnaire (15 minutes) after the computer aided session and another questionnaire (15 minutes)at the end of internship round |
