1st generation mouthwash
Less Substantivity
2nd generation
Proven substantivity and antibacterial properties
What year did the ADA start
1931
Community water fluoridation
Grand Rapids, Michigan added fluoride to the areas water supply in 1945
Primary mineral in teeth
Calcium hydroxyapatite
Calcium fluoroapatite
Fluoride can be substituted to create, more stable in acidic environment
Fluoridated water lowers tooth decay by
25 % over a persons lifetime
What % of the population can access fluoridated water supply
74%
Systemic intake
Ingested and circulated throughout body. Fluoride is made available to teeth during formation as well as in saliva
Topical
Direct exposure to erupted teeth
Optimal concentration of water Fluoridation
0.7ppm
Acute toxicity
Rapid ingestion of excessive quantities over a short time
Chronic toxicity
Long term ingestion of a higher than therapeutic dose
Certainly leather dose CLD
Adults- 5-10g
Children- 0.5-1.0 g
Dental fluorosis
Chronic ingestion, mottled to pitted appearance in most incidence more resistant to Carie’s but have cosmetic problems
How much toothpaste would you need to eat before it would kill you
24- 6oz tubes- adult
Fluoride mechanism of action for desensitization
Occlude dentin tubules
Systemic fluoride
Longer lasting, in the water, supplements and foods, not for pregnant women
Interpersonal communication
Communication between 2 people or in a small group
Subjective data
Perceptions, values, emotions, knowledge, needs, wants
Informed consent
Pts understand and accept treatment
Liability
In 1901 Dr. Fredrick McKay noticed a stain in a specific area
Colorado brown stain
Triclosan is used to prevent what
Supragingival calculus
Which mouth rinse is linked to oral leukoplakia
Sanguinarine mouth wash
Where is the heavies location of subgingival calulus
Interproximal
How many days does it take for rapid calculus to form
10 days
Active ingredient that is used to fight calculus
Triclosan
Social interaction
Between people who come together to share ideas to solve a problem
Basic communication theory
People are more likely to feel a commitment to a goal if they share in its development and if the goal meets their individual needs
CARE
Comfort, Acceptance, Responsiveness, Empathy
Factors that influence goal development and commitment
Interest, Beliefs, Time, Ability/dexterity, Resources
Informed refusal
Persons choice not to accept treatment after being fully educated about risks and benefits, and alternatives associated with treatment
Assessments (objective data)
Health history, personal history, E&I, Periodontal exam, Restorative exam, Radiographs, Vital signs
Assessments (subjective data)
Perceptions, values, emotions, knowledge, comfort, acceptance, Responsiveness, needs ,wants
In planning
Pt should be co-therapist; active participant in development of treatment plan
Preventive

Acellular, thin, formed by proteins, carbohydrates, lipids, forms with 30-90 minutes

Roles of acquired pellicle

Does
Sub gingival calculus ____ develop be direct extension from supra gingival calculus
Does not
