Chapter 29 Flashcards
Describe Type 1 Embrasure
Interdental papilla fills the gingival embrasure
Describe Type 2 Embrasure
Moderate recession;
Describe Type 3 Embrasure
Severe recession;
What is Embrasure?
V-shaped space next to the contact area of adjacent teeth
What is the Col?
Contact area of two teeth; the depression in the gingival tissue under a contact area between the lingual (palatal) papillae and facial papillae
What can floss be made of?
Silk, Nylon, PTFE (Polyetrafluorethylene)
A substance used for irrigation is called __________.
irrigant
Flushing of a specific area or site with a stream of fluid; application of a continuous or pulsated stream of fluid to a part of the body for a cleansing or therapeutic purpose is called ____________
irrigation
As ___________ occurs, dental floss may still be used, but greater time, effort, and dexterity are required for complete removal of dental biofilm from the exposed proximal tooth surfaces.
recession
What is the recommended total length of floss or tape to be dispensed for flossing?
12 to 15 inches
Which floss aid is used for biofilm and debris removal around orthodontic appliances or under fixed partial dentures?
Floss threader
A cleft in the gingival margin, usually at a mesial or distal line angle of a tooth, where dental floss was repeatedly applied incorrectly is called a __________.
Floss cleft
Between anterior teeth in contact, there is a _________ papillae with a ___________ shape.
Single, pyramidal
A floss holder can be helpful for who?
- A person with a disability
- A parent or caregiver serving a child or patient
What are advantages of patient applied daily irrigation?
Reduction in gingivitis
Fewer pathogenic organisms
Improved accessibility in difficult to reach areas
True or False. The standard jet tip placed supragingivally can penetrate below the gingival margin 44% to 71% of the pocket depth.
True
Waxed floss provides a smooth or slippery surface to slide through contacts and helps to prevent trauma to soft tissue. Wax also provides strength and durability during application and the chance of shredding or breakage is reduced.
Both statements are true
Flossing should begin ____________.
At the distal surface of the most posterior teeth
Floss/yarn combinations are known as _____________
Tufted floss
What are the two types of interdental brushes?
- tapered or cylindrical brushes with plastic handles
- tapered or cylindrical small insert brushes with reusable handles
What is the procedure for use of the interdental tip?
trace along the gingival margin with the tip positioned just beneath the margin
An interdental brush is indicated for use when:
sufficient space is available for the insertion of the brush without excess force
An interdental tip is best described as a __________
conical or pyramidal flexible rubber tip attached to the end of the handle of a toothbrush or on a separate plastic handle
A wooden interdental cleaner should be replaced for each arch or quadrant because ________________.
Wood may become splayed
When an antimicrobial agent is used in an oral irrigation system, which of the following is most likely to occur?
The reduction of supragingival and subgingival biofilm and gingivitis is enhanced
