Abstract

The purpose of this study is to investigate the standardization of infection control methods during dental implant placement surgery. <br>We examined the contamination of the blood and body fluids scattered on personal protective equipment (PPE) which was worn by an assistant during surgery. Organic matter that was attached to face-shields and gowns was wiped with a cotton swab and detected using Coomassie Brilliant Blue for determination of protein. <br>Further we examined the effect of the cleaning process for reusable implant drills by using the Adenosine Triphosphate (ATP) bioluminescent method. <br>As the result, organic matter was detected from the sleeves and abdomen areas as well as the chest of the gowns. In addition organic matter was also detected from the all face-shields used in additional advanced surgery for bone augmentation. ATP value was significantly (P<0.05, paired t-test) less in the drills which were washed in both ultrasonic cleaner (US) and washer-disinfector (WD) than that in the US only. <br>In conclusion, the assistant as well as the operator should wear PPE such as the long gown with long sleeves and the face-shield to protect from infections during surgery. Further, in the use drills, single use is desirable, because a very small amount of ATP was detected in the drills cleaned by both UC and WD.
