A

too much Fluoride

20
Q

________
PROS
•Proven efficacious in decreasing caries, especially in early-childhood
•Easy to apply following oral exam and prophylaxis
•Easy to follow post-op instructions
CONS
•Leaves a thin-visible film on teeth that some patients do not like
•Possible allergies linked to specific brands of fluoride varnish

A

Fluoride Varnish-5% NaF

21
Q
  • First investigated in 1969 as part of a PhD student’s thesis in Japan (Mizuho Nishino)
  • She combined the antimicrobial properties of silver with the benefits of high dose fluoride
  • This formulation additionally resulted in a precipitate that occluded dentinal tubules and reduced hypersensitivity
  • This product initially emerged from dental public health researchers in the developing world, where access to oral health care was extremely limited
A

Silver Diamine Fluoride

22
Q

Mechanism of action of _____
Fluoride and silver are made soluble in water by the addition of ammonia
•The silver ions are a broad-spectrum antimicrobial that has high biocompatibility and low toxicity in humans
•These ions act as tiny ‘silver bullets’ that damage and degrade bacterial cell walls, disrupt bacterial DNA synthesis and replication and disrupt intracellular metabolic activity, eventually leading to cell death
•The killed bacteria further act as a carrier for silver ions and can kill living bacteria nearby in a process known as the “zombie effect”
•Once applied, a physical barrier precipitates out of the clear solution onto the carious lesion
•2 products form–silver phosphate which acts as a reservoir of phosphate ions, and calcium fluoride, which is a pH-regulated fluoride supply available during cariogenic challenge
•Free silver ions in the lesion are reduced by environmental oxygen and turn the lesion black, which is the major non-medical side effect of SDF

A

Silver Diamine Fluoride

23
Q

How many ppm does 5% SDF solution contain?

A

44,800 ppm

24
Q

When to use ______:
•Dentin hypersensitivity
•Uncooperative patients (i.e., children or patients with cognitive disabilities), root surface caries on elderly patients with existing restorations, patients without access to restorative care, difficult to treat lesions

A

SDF

25
Q

Fluoridate _____ is not considered a therapeutic/preventive agent for caries

A

•Xylitol

33
Q
  • Decreases bacterial metabolism and produces a drop in dental plaque pH
  • Reduces the volume and amount of supragingival plaque due to a reduced production of extracellular polysaccharides and biofilm matrix
  • Promotes the selection of xylitol-resistant mutans streptococci
  • Stimulates salivary secretion
A

•Xylitol

34
Q

At least ____ of xylitol per day needed to achieve optimum therapeutic effect on S. mutans
