JVD 2020 #1 Evaluation of Efficacy of a Dental Chew to Reduce Gingivitis, Dental Plaque, Calculus and Halitosis in Toy Breed Dogs; Mateo

Question 1

What dog breeds were included in the study? Which had significantly higher gingivitis, plaque, calculus and VSC concentration as a breed?

Answer 1

8 Yorkshire Terriers & 9 Chihuahuas

Yorkshire terriers had significantly worse scores

Question 2

Modified Logan & Boyce plaque index

Answer 2

Quantify plaque accumulation on the buccal surface of the tooth using a disclosing solution and total plaque accum assessed by combination of estimate for area of tooth covered by dye and intensity of color to estimate thickness of plaque

Question 3

What were the significant reductions in mean gingivitis, plaque, calculus and halitosis (volatile sulfur compounds)?

Answer 3

• 20% gingivitis
• 15% plaque
• 35% calculus
  and -19% VSC compared to when not receiving a daily chew

Question 4

What did the dental chews contain to reduce plaque, calculus, gingivitis?

Answer 4

Vitamin C
Zinc
Sodium phosphate salts (sodium hexametaphosphate)

Question 5

What volatile sulfur compounds are most frequently associated with oral malodor?

Answer 5

hydrogen sulfide (H2S)
methyl mercaptan (CH3SH)

Question 6

How does Vit C work for oral health?

Answer 6

Antioxidant, involved in collagen synthesis

Question 7

How does zinc work for the dental chews?

Answer 7

Zinc ions inhibit bacterial growth in perio dz. Reduce malodor by reacting chemically with hydrogen sulfide.

Question 8

How do sodium phosphate salts like sodium hexametaphosphate aid work for dental chews?

Answer 8

They are calcium chelators shows to prevent calculus formation in dogs by inhibiting hydroxyapatite crystal growth and dental plaque mineralization
