CAMBRA Caries Management By Risk Assessment Scientifically proven
Evidence based Patient specific
5
Prevalence of Caries 77.9% of 17 years olds have dental caries
Low socioeconomic status increases risk Source: U.S. Department of Health and Human Service. Oral Health in America: A Report of the Surgeon General. Rockville, MD: U.S. Department of Health and Human Services, National Institute of Dental and Craniofacial Research, National Institutes of Health, 2000.
6
Introduction to CAMBRA—Caries Management by Risk Assessment
“What am I doing to help the students prevent more cavities from forming?”
7
Treating Carious Lesions vs. Treating the Cause of Carious Lesions
Failure to treat the cause of the caries lesions is like lathering dirty dishes and putting them in greasy rinse water. You’ll just have to lather them again.
8
Topics Caries balance and imbalance Caries risk assessments
Therapeutic regimens Student self-responsibility JC oral health & wellness team-members’ responsibility
9
Agenda Pre-test CAMBRA Discussion Post-test Webinar evaluation
10
Learning Objectives After participating in this webinar, the participant should be able to: Understand the role of caries risk assessment in prevention Understand how caries is an infectious disease in which the balance between cariogenic oral biofilm and the tooth becomes compromised Describe the components of the CAMBRA approach Put all of the learning objectives on one slide.
11
CAMBRA Principles Modification of the oral flora to favor health
Patient education and informed participation Remineralization Minimal operative intervention
12
Definitions Dental caries—an infectious disease leading to loss of mineralized tissue in the tooth structure Risk assessment—determining the risk for tooth decay in the future Caries balance—balance among disease indicators, risk factors, and protective factors Caries management—altering the balance between caries pathological and protective factors

15
CAMBRA Clinical Study Conclusions
The Caries Balance concept is confirmed Fluoride alone cannot overcome a high bacterial challenge Restorations don’t reduce bacterial loading Chemical therapy markedly reduces level of new caries
16
Biofilm Due to time constraints and the broad topic matter we are covering today. It is my intent to briefly cover what biofilms are and their role in the carious process. Dental Plaque
17
What are biofilms? “Biofilms are communities of micro-organisms encased within an extra cellular polymeric slime (Eps) matrix living on surfaces.”(1) Biofilms form when bacteria are exposed to a wet surface.
18
Where do we see biofilms?
They are everywhere! We see them on kitchen surfaces, bathrooms, fish tanks, coffee mugs, and in our mouth. Dental plaque is a form of biofilm.

21
Bioflims and Carious Lesions
How do biofilms lead to cavitation? Should be lesions?
22
Low pH This is the most important fact to understand. Without an acidic environment (pH of 4.8 and lower) there would be no demineralization and cavitation.
23
What Creates a Lower pH? Initial changes in environment due to any one factor: saliva flow decreases, poor diet, or poor homecare, can lead to an acidic pH in the mouth.
24
Demineralization Anaerobic, acid-producing bacteria in plaque biofilm produce and increase amount of acid due to fermentation, causing the pH of the biofilm to lower and demineralization to occur. Once demineralization occurs, hydroxy and fluorapatite become unstable in the tooth and are leached out. Bacteria enter the tooth and a cavity is born.
25
Bacteria No one particular bacteria species causes carious lesions.
“Good biofilm bacteria” have been found to adapt and produce acid once the pH drops as well.
26
The Caries Balance Protective Factors Pathological Factors
Saliva flow and components Fluoride - remineralization Antibacterials - chlorhexidine, xylitol, new? Pathological Factors Acid-producing bacteria Frequent eating/drinking of fermentable carbohydrates Sub-normal saliva flow and function Caries No Caries Featherstone, Comm Dent Oral Epidemiol, 1999

The Caries Imbalance Protective Risk Factors Factors

Self-Management Vital Behaviors
What are two vital behaviors that you feel will help you avoid signs of caries disease? Why did you pick these two vital behaviors? What can you see getting in the way of making these vital behaviors habits? What are some ideas you have to overcome those obstacles? How will you feel when your vital behaviors become habits?

Effectiveness of Therapeutics

Role of Therapeutics
42
Balancing the pH issue pH positive products of 6.8 or greater Xylitol
Combat xeristomia Keeping biofilm bacterial levels in check
43
Role of Health Education
44
“Not everything faced can be changed,
but nothing can be changed until it is faced.” -James Baldwin, writer and novelist I love this quote. I think this gives a good perspective of what we are doing with Cambra. In 2000, Mourandian noted in the JAMA, Dental caries is the most common chronic childhood disease. 5X more prevalent than childhood asthma. Education is our best chance of promoting prevention. 44
45
Role of Health Education
Understanding their sense of “self” What is their dental I.Q.? How do they view the dental profession? Be an active participant on campus 45
46
Understanding Their Sense of “Self”
These students are acutely aware of what they don’t have. Loss of teeth and replacement with bridge work, flippers, dentures, or even implants is seen not only as physically diminishing, but as placing them at the very bottom of the socio-economic totem pole.
47
What is Their Dental I.Q.? Do they understand basic oral hygiene?
Have them demonstrate their homecare skills. Understanding the environment from which they came. If they moved a lot, lived on the streets, or had a history of substance abuse, oral hygiene was most likely not a taught skill or priority. Be careful of dental jargon. Words like plaque, tarter, calculus, periodontal disease, or root canal, are all foreign to the majority of Job Corps population.
48
How Do They View the Dental Profession?
Many of our students have never been to a dental practice, are from foreign countries, or sought cheap quick fixes that yielded poor results. In other words, they are terrified of us. This will result in broken appointments, miscommunication, and lack of compliance. All efforts should be made to promote a safe and compassionate environment.
49
Be an Active Participant on Campus
Classrooms Keep information simple, understandable, and impactful. Walk the campus grounds This allows students to see you outside the clinic, and ask questions in a non- clinical setting. Participate in other campus programs At my center I lecture in weight management class, diabetes clinics, tobacco cessation programs, etc. Always relating dentistry to the field I am participating in. Host motivational speakers Gruen Von Behrens with the help of local sponsors recently visited our campus and spoke about the effects of tobacco use. Use Stem wall for plumbing student with fractured root of #7. I understand we are on limited budgets, but many communities have programs willing to sponsor youth programs. 49
