JVD 2019 #2 Two Randomized Trials Demonstrate Lactic Acid Supplementation in Pet Food Inhibits Dental Plaque, Calculus and Tooth stain in Cats; Scherl

Question 1

What were the 2 studys?

Answer 1

2 separate feeding trials

1: Data collected on a monthly basis for 3 months
2: Randomly assigned 24 cats to test or control groups for 1 year; data collected at 6 and 12 mo

Question 2

How does sodium hexametaphosphate work?

Answer 2

Calcium chelator

Reduce the amount of salivary calcium available to mineralize plaque into calculus

Question 3

How does lactic acid work as a chelating agent?

Answer 3

Produces soluble complex calcium lactate thereby sequestering calcium that would be used to form calculus

Question 4

What method was used to assess plaque, calculus and stain?

Answer 4

For both the 3-mo and 1-year studies, the Logan/Boyce dental substrate quantification method was used

Question 5

What was the % difference between the plaque, calculus and stain between the control and test groups at 6 mo and 12mo?

Answer 5

About 30% less Plaque and calculus at 6mo and plaque at 12 mo. About 25% reduction in calculus at 12 mo. 36-33% difference in stain.

Question 6

tooth surface pH of healthy cat?

Answer 6

8.65
