b) Brush at least twice daily with a fluoridated toothpaste, with at least 1350ppm fluoride, clean daily between the teeth to below the gum line after toothbrushing, and use a fluoride mouthrinse daily (0.05% NaF-) at a different time to brushing
c) Clean daily between the teeth to below the gum line before toothbrushing, and brush at least twice daily with a fluoridated toothpaste, with at least 1350ppm fluoride
d) Brush at least twice daily with a fluoridated toothpaste, with at least 1350ppm fluoride, and use a fluoride mouthrinse daily (0.05% NaF-) at a different time to brushing

b) For the treatment of periodontitis and where improvements in plaque control are required
c) For the treatment of gingivitis and where a patient is unable to clean interdentally effectively
d) In all circumstances
8. When used for 6 months or longer, which mouthrinse formulations have been found to be most effective in controlling plaque as an adjunct to standard care*?
a) Essential oils and chlorhexidine
b) Chlorhexidine and cetylpyridinium
c) Cetylpyridinium and essential oils
d) Chlorhexidine and delmopinol

a) Gingivitis and diabetes
b) Periodontitis and peri-implantitis
c) Gingivitis and peri-implantitis
