Bass Method - Most widely used method. Bristles are angled at a 45 degree angel
towards the gingiva.
Stillman's Method - Bristles are positioned on the gums rather than into the
pockets and directed at a 45 degree angle.
Charter's Method - Bristles are directed occlusally, away from the gingiva. Useful
for cleaning orthodontic brackets, prosthesis, and areas treated with surgeries.
Fone's Method - Bristles are moved in large circular motion on the buccal and
lingual surfaces. Useful for children, those physically impaired, or adults who lack
manual dexterity.
Fluoride Varnish - -Dries immediately upon contact with saliva.
-Does not require a professional prophylaxis before hand.

-Do not eat, drink, or smoke for 30 minutes.
-Most popular types are 1.23% APF and 2% Neutral sodium fluoride.
Stannous Fluoride - -0.4% available for non-prescription use.
-1% neutral sodium fluoride gels available for prescription use.
-Can cause extrinsic staining (especially in patient's with inadequate plaque
control).
Acidulated Phosphate Fluoride (APF) - -Do NOT use of composites, porcelain, or
sealant materials as it causing pitting and roughening.
-Also avoid on root surfaces.

Neutral Sodium Fluoride - Agent of choice on root caries, implants, cosmetic
restorations, and reduced salivary flow.
Second trimester - safest trimester for dental treatment.

progesterone. Hormones increase can cause exaggerated gingival response to
microorganisms.
Pyrogenic granuloma (Pregnancy tumor) - localized area of gingival enlargement,
typically involving interdental papilla, usually diminishes after delivery of baby.
What category of LA can use administer to a pregnant patient? - Category B
(lidocaine and prilocaine)
