JVD 2020 #1 Evaluation of Efficacy of a Dental Chew to Reduce Gingivitis, Dental Plaque, Calculus and Halitosis in Toy Breed Dogs; Mateo Flashcards
What dog breeds were included in the study? Which had significantly higher gingivitis, plaque, calculus and VSC concentration as a breed?
8 Yorkshire Terriers & 9 Chihuahuas
Yorkshire terriers had significantly worse scores
Modified Logan & Boyce plaque index
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
What were the significant reductions in mean gingivitis, plaque, calculus and halitosis (volatile sulfur compounds)?
- 20% gingivitis
- 15% plaque
- 35% calculus
and -19% VSC compared to when not receiving a daily chew
What did the dental chews contain to reduce plaque, calculus, gingivitis?
Vitamin C
Zinc
Sodium phosphate salts (sodium hexametaphosphate)
What volatile sulfur compounds are most frequently associated with oral malodor?
hydrogen sulfide (H2S) methyl mercaptan (CH3SH)
How does Vit C work for oral health?
Antioxidant, involved in collagen synthesis
How does zinc work for the dental chews?
Zinc ions inhibit bacterial growth in perio dz. Reduce malodor by reacting chemically with hydrogen sulfide.
How do sodium phosphate salts like sodium hexametaphosphate aid work for dental chews?
They are calcium chelators shows to prevent calculus formation in dogs by inhibiting hydroxyapatite crystal growth and dental plaque mineralization
