B) “Because insurance requires it”

effective?
A) Daily chlorhexidine rinses
B) School-based fluoride mouthrinse program
C) Individual sealants in private clinics

efficiently and are evidence-supported for caries reduction.
6. Which ethical principle is most directly applied when a
hygienist provides full disclosure of treatment risks and
