✔✔Informed refusal - ✔✔Document and patient needs to sign
✔✔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.
-Can eat and drink immediately after.
-Avoid brushing, rigorous rinsing, or hard foods for 3 to 4 hours.
-Easier and more effective method
✔✔Fluoride is recommended for patients who: - ✔✔-Have xerostomia
-High caries risk
-Undergoing cancer therapy
-Orthodontics
, ✔✔Fluoride Gel or Foam (office application) - ✔✔-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.
✔✔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.
✔✔When should a child's first dental appointment occur? - ✔✔-Within 6 months of the
eruption of the first tooth or before 1-year of age.
✔✔When should you first start brushing a child's teeth? - ✔✔-When the first tooth
appears.
✔✔Signs and Symptoms of erosion - ✔✔-dental caries from vomiting
-Perimolysis: erosion from vomiting mostly on the maxillary lingual surfaces. Raised
appearance of restoration margins.
✔✔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.
✔✔Attrition - ✔✔-Results from forces between the teeth.
-Wear on the incised and occlusal surfaces from grinding.
✔✔Abfraction - ✔✔-Biomechanical destruction related to fatigue, flexure, and
deformation of tooth structure.
-Can appear as a wedge-shaped lesion at the cervical third of the tooth.
✔✔What is the most effective public health measure to prevent tooth decay? -
✔✔Community Water Fluoridation
✔✔New recommended level of fluoride is? - ✔✔0.7 ppm
✔✔ASA 1 - ✔✔Normal, Healthy
