A: proximal

Q: Which of the following statements is true about the interdental anatomy?
- Between adjacent anterior teeth there are two papillae
- The papillae are connected by a col
- Col epithelium is thick and keratinized
- The col epithelium is very resistant to infection
- Between adjacent posterior teeth there is a single papillae and no col area
A: The papillae are connected by a col

Q: The col area becomes deeper when:

A: inflammation leads to edema

Q: Case Study 1
Mr. Larsen, a 52-year-old, has just moved into town and is new to this dental office. In completing initial oral assessments, Eric, the dental hygienist, noted straight line cuts on the anterior facial and lingual surfaces in the middle of the interdental gingiva. Mr. Larsen had periodontal probe depths from 1 to 3 mm, and his gingiva was stippled, pink, and firm. He also had moderate biofilm accumulations around his bridge in the lower left quadrant and minimal bleeding upon probing. Mr. Larsen reports brushing two or three times a day and flossing one to two times every day. When Eric asked him to demonstrate brushing and flossing, he noticed that Mr. Larsen used a 24-inch piece of floss and snapped it between the contact areas. He also noticed Mr. Larsen used a scrubbing technique when brushing. When Eric commented on his brushing and flossing technique, Mr. Larsen stated that he has always done it this way and no one has ever said anything about it before.

Reference: Ref 28-1

Open and read the attached case to answer the following question. What are straight-line cuts on Mr. Larsen's gingiva?
- Recession caused by malocclusion
- Gingival inflammation
- Floss cuts
- Trauma from vigorous brushing
A: Floss cuts

Reference: Ref 28-1

Open and read the attached case to answer the following question. The reason the straight-line cuts appear are because Mr. Larsen:
- snaps floss through the contact area
- uses a sawing motion to floss through the contact area
- does not use a sulcular brushing technique
- flosses too frequently
A: snaps floss through the contact area

Open and read the attached case to answer the following question. Excess pressure used when flossing is especially harmful to whom?

Open and read the attached case to answer the following question. Mr. Larsen asks Eric what type of floss he should use to prevent further floss cuts. Eric should recommend:
- to limit flossing
- unwaxed floss
- waxed floss
- gauze strips
A: waxed floss
