JVD 2019 #4 Qualitative and Quantitative Assessment of Alveolar Bone Destruction in Adult Rats Using CBCT, Kivanc

Question 1

Purpose of this study?

Answer 1

Compare grey value, surface area, and volumetric measurements of teeth with and without experimental periodontitis by CBCT

Question 2

Did statistically different changes occur in grey value, surface area, and volume measurements when comparing teeth with and without alveolar bone destruction?

Answer 2

Yes. All three showed stat. significant differences between teeth with and without alveolar bone destruction.

Question 3

How much did mean grey value decrease for teeth with alveolar bone destruction compared to healthy teeth?

Answer 3

56.46%

Question 4

How much did mean surface area decrease for teeth with alveolar bone destruction compared to healthy teeth?

Answer 4

81.89%

Question 5

How much did mean volume measurements decrease for teeth with alveolar bone destruction compared to healthy teeth?

Answer 5

78.56%

Question 6

What oral bacteria was used to induce periodontitis in rats?

Answer 6
