hygiene students at a nearby community college.
Data from the oral screening program indicate that the target
population has such a low incidence - ANSWER-The
independent variable is the outcome variable of interest.
Professionally administered (in-office) oral irrigation with 0.12%
chlorhexidine gluconate is - ANSWER-of little value because of
