Q

What is a clean tooth?

A

in pets as well as humans, the tooth is only “clean” immediately after a dental cleaning and polishing
- within minutes of cleaning a pellicle forms on tooth (peptides, proteins, glycoproteins), which act as an adhesion site for bacteria

in pets as well as humans, the tooth is only “clean” immediately after a dental cleaning and polishing
- within minutes of cleaning a pellicle forms on tooth (peptides, proteins, glycoproteins), which act as an adhesion site for bacteria

27
Q

GRAS

A

generally regarded as safe

- long history of ingestion with no adverse conditions

28
Q

What is involved in plaque formation?

A
  • oral bacteria
  • food particles
  • salivary mucin
29
Q

What is plaque?

A

sticky film of bacteria and sugars that can harden into tartar if not removed

30
Q

What makes up calculus (tartar)?

A

Salivary minerals

31
Q

What process is involved in calculus formation?

A

supersaturation and crystallization of salivary minerals

  • cosmetic by nature, but can serve as deposition point for more plaque
  • can also irritate the gum line by contact
32
Q

HMP - regulatory

A

In 2001 - HMP was ok for use as a phosphorus source but not a dental agent

In 2007 - HMP and polyphosphates were widely used across the industry

33
Q

Tissue damage associated with gingivitis?

A
  • bacteria under stolen gum line –> red and inflamed

- bacterial toxins

34
Q

What is responsible for the periodontal pocket associated with gingivitis?

A
  • anaerobic bacteria (bacterial penetration)
  • toxins
  • host response (reduced immune response in that area)
35
Q

When gingivitis gets to be so bad, what is the only cure?

A

tooth extraction

36
Q

What does VOHC do?

A

design dental health studies

  • exist to recognize products and meet pre-set standards of plaque and calculus (tartar) reduction in dogs/cats
  • products receive VOHC seal of acceptance following review of data from trials conducted according to VOHC protocol
  • seal awarded to diets that meet or exceed criteria
37
Q

What is the first step to good dental care?

A

professional cleaning

38
Q

What is kibble designed to do?

A

remove tartar

- tough and oversized kibble = Hills TD

39
Q

With the use of kibble, the benefits are limited to?

A

the chewing surface

- not a universal solution but does help

40
Q

What is the purpose of polyphosphates?

A

used in human dental products as chelates to help control tartar deposition rates

41
Q

Sodium hexametaphosphate (sHMP)

A
  • chelant
  • sodium phosphate “glass” or long chain polymer (~21 phosphate unit)
  • soluble in water and possess sequestering ability (chelates calcium)
  • polyphosphates = GRAS
  • kibble coating with HMP
42
Q

HMP target tissue?

A

entire mouth

43
Q

GRAS

A

generally regarded as safe

- long history of ingestion with no adverse conditions

44
Q

How does tartar form?

A

mineral precipitation from the saliva

45
Q

HMP mechanism of action

A
  • polyphosphates work in saliva by chelating calcium and attaching to surface of tooth to block additional calculus growth
46
Q

HMP degradation cycle

A
  • the longer chains breakdown the smaller units

- each smaller unit still has the ability to chelate calcium until it becomes elemental phosphorus

47
Q

What happens to HMP in the body over time?

A
  • in the mouth, oral bacteria breaks down the dental agent into phosphorus which is absorbed by the body
  • the the stomach, the digestion process also breaks down the dental agent into phosphorus
48
Q

HMP - regulatory

A

In 2001 - HMP was ok for use as a phosphorus source but not a dental agent

In 2007 - HMP and polyphosphates were widely used across the industry

49
Q

Experimental support - % reduction in plaque formation with the use of sHMP?

A

45-50%

50
Q

Why is it important to have a within dog comparison?

A

to control for the fact that every animal has a different mineral composition and different bacterial count in their mouth

51
Q

VOHC

A

veterinary oral health council

52
Q

What does VOHC do?

A

design dental health studies

53
Q

Rapid prototyping before animal based studies - in vitro methods

A

crystal inhibition method to stimulate oral cavity and HMP release

  • assesses mineralization rates
  • coating releases quickly and embeds within the crystal structure to provide barrier to tartar formation
54
Q

What may be another benefit associated with dental chews?

A

may have behavioural component = mental health benefits

55
Q

What is the difference between plaque and tartar? What is tartar also known as?

A

Plaque is the sticky film of bacteria and sugars that can harden into tartar if not removed

Tartar = calculus
- salivary minerals that supersaturate and crystallize on teeth

56
Q

What is the ultimate fate of dental diet HMP within the body and how should this effect diet formulation?

A
  • oral bacteria or the digestive environment of the stomach will break HMP into phosphorus
  • then absorbed by body as any other P source would be
  • must be included as a P source in formulation
57
Q

True or false - the VOHC awards a seal of acceptance after performing trials on diets that meet or exceed their criteria?

A

False

- they don’t actually test thesis products themselves, they review data from trials

58
Q

Compare and contrast the use of kibble to with tarter vs. the use of polyphosphates

A

kibble designed to fight tartar has an increased size compared to average kibble
- this increased SA allows for kibble to come into contact with the teeth and help wear away the tartar on the surface

Polyphosphates work in the saliva by chelating calcium and preventing it from binding to the surface of the teeth
- also binds directly to the surface of teeth to further block calculus growth

  • kibble is effective but only reaches teeth that come into contact with the kibble; polyphosphates are much more effective at protecting the entire mouth
59
Q

Describe the cycle between plaque and tartar formation and what can be done to interrupt this cycle?

A
  1. professional learning
  2. bacteria and food particles combine to form plaque
  3. plaque hardens into tartar –> dental problems
  • brushing regularly can interrupt this
60
Q

What are the 2 mechanisms of action of HMP in the mouth to help control tartar deposition rates?

A
  • chelates calcium in saliva

- attaches to the tooth surface to block additional calculus growth

61
Q

What are 2 factors that allow HMP in kibble to be available to its target tissue?

A
  1. put on the outside of kibble

2. very quickly solubilized in the saliva

62
Q

When is the only time that we see clean teeth and why is this?

A

Immediately after a dental cleaning and polishing. Within minutes of cleaning a pellicle layer forms composed of peptides, proteins and glycoproteins which allows bacteria to adhere to the surface of the tooth

63
Q

True or false - in 2001, HMP was ok for use as a P source and dental agent

A

False

  • it was only allowed for use as a Ph source
  • a self affirmed GRAS was submitted to the FDA and was not officially approved for the use in pet care products for calculus control until 2007
64
Q

How was it decided to put HMP on the outside of the kibble rather than inside?

A

Through in-vitro methods

- a crystal inhibition method was used to stimulate the oral cavity and HMP release
