Gross soil tissue, body fat, blood, and other body substances. If left on instruments too long it makes them more difficult to clean and can damage instruments. Importance of point of use treatment removes gross soil, prevents damage to instruments, prevents cross contamination, returns instruments in a timely manner, keeps others safe Departments need a holding area for dirty instruments until they can be returned to SPD these should be covered with a biohazard signage. This al...

ODP EXAM 1 WITH COMPLETE SOLUTIONS GRADED A+ Describe the biofilm matrix and what purpose it serves - Answer-Bacterial biofilm forms a matrix for calculus formation. Explain how bacteria can overcome the host defense capacity and why everyone doesn't get caries and/or periodontal disease if they have biofilm - Answer-If biofilm is disrupted, caries and periodontal disease can be controlled. List disruptions of biofilm: - Answer-Tooth brushing, flossing (removes biofilm and subgingivally,...
