1. Bass Method: Most widely used method. Bristles are angle at a 45 degree
towards the gingiva.
2. Stillman's Method: Bristles are positioned on the gums rather than into the
pockets and directed at a 45 degree angle.
3. Charter's Method: Bristles are directed occlusally, away from the gingiva. Useful
for cleaning orthodontic brackets, prosthesis, and areas treated with surgeries.
4. 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.
5. Fluoride Varnish: -Dries immediately upon contact with saliva.
-Does not require a professional prophylaxis before hand.
-Can eat and drink immediately after.
-Avoid brushing, rigorous rinsing, or hard foods for 3 to 4 hours.
-Easier and more effective method
6. Fluoride: This product is recommended to patients with:
-Xerostomia
-High caries risk
-Undergoing cancer therapy
,-Orthodontics
7. Fluoride Gel or Foam (office application): TYPE OF FLUORIDE:
-Applied onto tray and placed in patient's mouth usually for 4 minutes (Read
manufactures label).
-Do not eat, drink, or smoke for 30 minutes.
-Most popular types are 1.23% APF and 2% Neutral sodium fluoride.
8. Stannous Fluoride: TYPE OF 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).
9. Acidulated Phosphate Fluoride (APF): TYPE OF FLUORIDE:
-Do NOT use of composites, porcelain, or sealant materials as it causing pitting and
roughening.
-Also avoid on root surfaces.
10. Neutral Sodium Fluoride: TYPE OF FLUORIDE:
Agent of choice on root caries, implants, cosmetic restorations, and reduced salivary
flow.
11. Second trimester: Safest trimester for dental treatment.
12. Pregnancy gingivitis: -Caused by an elevation of hormones estrogen and
progesterone. Hormones increase can cause exaggerated gingival response to
microorganisms.
,13. relative contraindication (gas interferes with the absorption of B-12 and
other nutrients).: Can you use Nitrous oxide sedation and general sedation on a
pregnant patient?
14. NITROUS OXIDE: Contraindications for ?
-COPD
-Upper respiratory infection
-Emotional/Behavioral instability
-Pregnancy
-Cystic fibrosis
-Lack of communication (language barrier)
15. Pyrogenic granuloma (Pregnancy tumor): Localized area of gingival enlarge-
ment, typically involving interdental papilla, usually diminishes after delivery of
baby.
16. Category B (lidocaine and prilocaine): What category of LA can use admin-
ister to a pregnant patient?
17. Early Childhood Caries (ECC) index: WHAT TERM:
-presence of 1 or more areas of decay on a child younger than 6 years of age
18. Severe-Early Childhood Caries (S-ECC) index: WHAT TERM:
-Presence of decay in a child younger than 3 years old.
19. -Within 6 months of the eruption of the first tooth or before 1-year of
age.: When should a child's first dental appointment occur?
20. -When the first tooth appears.: When should you first start brushing a child's
teeth?
21. -Anorexia Nervosa
, -Bulimia Nervosa: Erosion causes by these eating disorders:
22. Anorexia Nervosa: EATING DISORDER:
-Extreme weight loss caused by self-starvation, excessive exercise, use of laxatives, self-
induced vomiting.
23. Bulimia Nervosa: EATING DISORDER:
-compulsive disorder that involves periods of starvation, binging, and purging.
24. Signs and Symptoms of EROSION: Signs and Symptoms of ?:
-Dental caries from vomiting
-Perimolysis: from vomiting mostly on the maxillary lingual surfaces. Raised
appearance of restoration margins.
25. Abrasion: -V-shaped notch in the gingival portion of the facial aspect of the
tooth.
-Results from forces of friction between the teeth or external objects.
-Can happen from improper brushing technique or the use of a toothpick or pipe.
26. Attrition: -Results from forces between the teeth.
-Wear on the incised and occlusal surfaces from grinding.
