Title: Dental Health in Veterinary Medicine


1
Dental Health in Veterinary Medicine
2
What do animals use their teeth for?
  • Chewing
  • Catching prey
  • Self defense

3
What do vets look for in animal teeth?
  • Look for signs of disease
  • Look for broken and/or missing teeth
  • Look for occlusal relationships
  • Approximate the age of the animal

4
How about these?
See slide note
5
Do animals get dental disease?
  • Periodontal disease affects 85 of cats and dogs
    over 5 years of age

6
How can veterinarians tell if an animal has tooth
pain?

7
What can dental disease do to my pet?
  • Cause pain
  • Result in tooth loss
  • Make eating difficult
  • Lead to infections
  • Lead to inactivity

8
What causes periodontal disease?

  • Bacteria forms plaques on the teeth
  • Plaque hardens to form calculus
  • Plaque starts to touch the gums
  • Bacteria and immune system release destructive
    chemicals
  • Destroys the attachment of the tooth to the gum

9
Healthy gums
  • Pink gums
  • Smooth
  • Shiny

10
Stage 1 Periodontal disease
  • Red gums
  • Swollen gums

11
Stage 2 Periodontal disease
  • Infection around the teeth
  • Shallow pockets
  • Bone loss

12
Stage 3 4 Periodontal disease
  • Deep pockets
  • Bone loss
  • Loose teeth

13
How can we prevent periodontal disease?
  • Any ideas?

14
How can I help my pet?
  • Brush your pets teeth!
  • Lift lips
  • Rub their gums and teeth
  • Brush gently with a finger brush or soft
    toothbrush
  • Brush gently with pet toothpaste on the
    fingerbrush or toothbrush

Get your vet to show you how and do it only under
parental supervision so you dont cause harm.
15
Pet toothpaste
  • Some is flavored to taste like food
  • Does not contain fluoride. DO YOU KNOW WHY?
  • Contains enzymes. DO YOU KNOW WHY?

16
Pet chew toys
  • Gumabones

Pet chew toys
  • C.E.T. Dual Enzyme Chews
  • Rawhide delivers mechanical action that abrades
    plaque from teeth above the gum line.
  • Dual Enzyme System is activated by saliva to
    produce Hypothiocyanite ions which eliminates
    placque-forming bacteria.
  • C.E.T HEXtra Chews
  • Rawhide delivers mechanical action that abrades
    plaque from teeth above the gum line.
  • Saliva releases Chlorhexidine to provide
    sustained antiseptic action to eliminate
    placque-forming bacteria

19
  • Goat Hoof

20
Toothpaste Enzymes
  • Enzymes are target specific (they only break down
    specific kinds of starches or proteins)
  • The manufacturer may not always explain on the
    label what kinds of enzymes are in the
    toothpaste.
  • How well they work in the toothpaste may be
    debatable.
  • Enzymes are proteins. For more about how they
    affect
  • food, see our Web curriculum modules on
    digestion

22
What about cavities?
  • Do dogs and cats get cavities? not usually.
  • Do you know why? There are two main reasons.
    Hint cavities are caused by bacteria growing on
    trapped food.

23
Dental Research
  • Better technology for braces
  • Laser imaging for diagnosing early-stage
    periodontal disease
  • Zapping diseased gums with lasers
  • Improved implants for missing teeth

24
Human Dental Care Brushing
  • Brush after every meal, certainly before and
    after a nights sleep. Rinse well.
  • Bacteria in the mouth ends up irritating the
    gums, getting into bloodstream.

25
Human Dental Care Brushing
  • People with gum disease are more likely to have
    hardened arteries, heart attack, stroke, and even
    diabetes.
  • Teeth should be cleaned twice a year in a
    dentists office.

26
Human Dental Care Flossing
  • Insert strip of floss between each pair of teeth.
  • Work back and forth, up and down.
  • Rinse (note if you see residue even after
    brushing) See animation

27
Water Picks
  • Direct spray between each pair of
    teeth and front and back surfaces.
  • Note if any residue appears in the water as it
    drains out of your mouth. If brushing and
    flossing dont get it all, you may need to use
    water picks routinely.

28
Example NIH Research in Dentistry



  • Using bacterial gene sequences to identify
    strains that cause rapid tooth decay.

29
Plan for the study
Filling of an old cavity
New cavity forming
  • Oral bacteria in a large group of
    racially/ethnically diverse children will be
    tested to see if the bacterial gene sequence can
    predict which children will get severe cavities.

30
Expected benefit
  • Early identification of children at risk can lead
    to vigorous preventive treatment.
  • Teeth of such children can be sealed shortly
    after teeth emerge.

traps for food and bacteria.
