A patient has deep pockets and has had 3-month appointments with a dental
| | | | | | | | | | | | |
hygienist for many, many years. At each visit, the hygienists who have treated
| | | | | | | | | | | | |
her have performed periodontal instrumentation on the roots of all the teeth
| | | | | | | | | | | |
using a very firm, scraping stroke. After many years, the periodontal
| | | | | | | | | | |
instrumentation might remove a part of the periodontium. Which anatomical
| | | | | | | | | |
area of the periodontium could be removed from the root after years of
| | | | | | | | | | | | |
instrumentation?
,a. Periodontal ligament
| |
b. Gingiva
|
c. Cementum
|
d. Alveolar bone - Correct answer ✔c. Cementum
