SDN Members don't see this ad. (About Ads) After shadowing several dentists, an oral surgeon, and an orthodontist, I have noticed a similar trend: each doctor had very little regard for sterility. I saw handpieces and crowns dropped on the floor, they never changed lab coats or scrub tops (even if they went out to lunch in them), and there was never any mention about the cleanliness of the patient's face or clothes. To their credit, all of the doctors changed their gloves regularly (some changed their masks), and they all wiped down the operatories after each patient (at least their assistant did), but other than that it seemed pretty lax. Is this common? Is the risk of infection so low for the oral cavity that it doesn't really matter? Why aren't oral surgeries treated like other surgeries, with sterile drapes and the like?
