Summary

Background: Attention and awareness towards MSDs in the dental profession has increased considerably in recent years. From recent literature reviews, it is learned that prevalence of MSDs in dentists is 64-93%. It has been seen that the use of magnification systems not only improves the operator's visual capabilities, but also allows for a more correct posture, and to prevent the onset of back and neck disorders. Purpose and methods: Evaluate dentist posture during extraction of third lower molars depending on whether the operator uses the naked eye, surgical loupes or surgical microscope systems. Data will be evaluated through the index RULA (rapid upper limb assesment) to define whether there is a change in exposure to the risk of MSDs (Muskoloskeletal disease) and using fiducial markers for the movement analysis of the operator during the procedure.

Detailed description

Study design: randomized controlled clinical trial. Purpose: Evaluate dentist posture during extraction of third lower molars depending on whether the operator uses the naked eye, surgical loupes or surgical microscope systems. Methods: Data will be analysed through the index RULA (rapid upper limb assesment) to define whether there is a change in exposure to the risk of MSDs (Muskoloskeletal disease). Posture assessment will be based on 3-D data of the upper body, which can discriminate spatial displacements up to 2mm in translation and 1 degree in rotation. The surgical intervention will be performed under local anesthesia (mepivacaine 20 mg/ml with adrenaline 1:100000) and by the use of microscope (OPMI Movena S7) or surgical loupes or no magnifying system. During this session the following data will be collected for the study: 1. Demographic data (baseline) 2. Medical and dental history 3. Parameters related to the lower third molar 4. Radiographic tests 5. Marker operator position 6. Pre- and postoperative photographs Each patients will be recalled for follow-up visits at 7 days. During this session will be carried out the removal of stitches and data will be recorded as follows: 1. VAS pain and trismus. 2. Number of painkillers taken 3. Control photographs 4. Posse Scala
