1. Chapter 15 Preventive Dentistry

2. To help people have maximum oral health throughout their lives To achieve maximum oral health –Dental professionals must work together with patients to prevent new and recurring disease

3. Bacteria Various types of bacteria found in dental plaque, are responsible for –Dental Caries –Periodontal disease

4. Patient Education Partnership—between patient and dental health team Guidelines –Listen carefully –Instruct the patient on how to remove plaque –Assess the patient’s motivations and needs –Select the home care aids –Keep the instruction simple –Reinforce home care

5. Optimum Oral Health Patient education Use of fluorides Application of dental sealants Proper nutrition Plaque control program

6. Fluoride Primary weapon to combat dental caries Referred to as “nature’s cavity fighter” Provided through –Prescription-strength fluorides that are applied in the dental office –Nonprescription-strength, over the counter products for home use –Consumption of fluoridated bottled water or community water

7. Fluoride Systemic fluoride –Ingested in water, food, beverages or supplements Topical fluoride –Applied directly to the teeth through the use of fluoridated toothpaste, fluoride mouthrinses, topical applications (rinses, gels, foams and varnishes)

8. Dental Caries Cannot occur without dietary sugars. Cariogenic (caries-causing) –Sucrose-sugars –Maltose –Lactose –Glucose –fructose Non-cariogenic (do not cause caries) –Sugar substitutes Saccharine, aspartame, sorbitol, mannitol

9. Dietary Analysis Determines whether the patient’s current food intake is affecting his or her dental health. Food diary –Everything eaten each day for 1 week

10. Plaque Control Program Cannot remove all plaque on teeth every day, but it can be kept under control by: –Brushing, flossing and interdental aids Goal –Thoroughly remove plaque at least once daily –After plaque is removed it takes approximately 24 hours to re-form

11. Toothbrushes and Brushing Manual –There is not an ideal toothbrush for everyone Too many sizes, shapes and angles –Soft-bristled toothbrushes are recommended Automatic –Various types –When used properly, works as well as manual

12. Toothbrushing Methods Bass –This method is useful for all types of dental conditions, especially periodontal problems. With bristles pointed at a 45-degree angle into the gingival sulcus, vibrate the brush gently back and forth about 20 times. Move the brush forward and repeat. Rolling strokes –This method is useful for stimulation of the gingiva. Place the brush above the free gingiva with the bristles pointed toward the apices. Exerting light pressure, draw the brush toward the occlusal surface using a rolling stroke. Use a scrub technique on the occlusal surface

13. Modified Stillman’s –This method is useful for patients with hypersensitive gingiva or slightly reduced interdental papilla. Use the rolling stroke method while vibrating the bristles in a lateral motion. Charter’s –This method is useful for patients with severe loss of interdental papilla height, fixed prosthetic appliances, previous gingival surgery, or subsided ulcerative gingivitis. Perform the rolling stroke first to remove debris from the teeth. Direct the bristle tips toward the occlusal or incisal surface. Gently rotate the handle, flexing the bristles and bringing them into contact with the interdental tissues and exposed proximal surfaces. Vibrate the handle of the brush with a slow, circular motion.

14. Fone’s –This method is useful for small children or others with poor manual dexterity. First, occlude the teeth. Then, lightly press the bristles against the posterior teeth and the gingiva. Revolve the brush head in a fast, circular motion, using circles of large diameter. Continue the circular motion, and slowly move the brush head toward the anterior until all facial surfaces have been brushed. With the mouth open, use the same circular motion on the maxillary and mandibular lingual surfaces.

15. Dental Flossing/Tape Removes bacterial plaque and reduces interproximal bleeding Available in waxed and unwaxed Floss before brushing –Plaque needs to be removed interproximally first

16. Interdental Aids Used in addition for brushing and flossing –Not take the place of

17. Dentures Need to use denture brush to clean Nonabrasive cleaner

18. Nutrition The science of how the body uses food for development, growth, repair, and maintencance. Nutrients –Components in food that are needed by the body

19. Key Nutrients Carbohydrates Proteins Fats Water Vitamins Minerals

20. Food Guide Pyramid Fats, oils and sweets Milk, yogurt and cheese group Vegetable group Meat, poultry, fish, dry beans, eggs, and nuts group Fruit group Bread, cereal, rice, and pasta group

21. Eating Disorders Bulimia –Referred to as “bingeing and purging” disorder –Believes self worth is related to being thin –Easy to recognize because their teeth have severe wear on the lingual surfaces caused by stomach acid (from vomiting) Anorexia Nervosa –Self-starvation-abnormal fear of becoming fat

22. Eating Disorders, cont. Female Athlete Triad –Affects young female athletes –Eating disorder/includes restrictive dieting, overexercising, weight loss, and lack of body fat –Results are osteporosis and amenorrhea –Dental risk—enamel decalcification, increased caries, periodontal and soft tissue inflammation

23. Management of Eating Disorders Anorexia and bulimia are considered psychiatric diseases Dental professionals are often first to discover disorders

24. Healthy Habits Eat right—five servings of fruits and vegetables daily Keep bones strong—sufficient calcium Protect immune system—eat whole grains, green leafy vegetables, seafood, lean meats and moderate amounts of vegetable oils and trace minerals Maintain a healthy body weight Exercise—aerobic exercises
