Exam 1 CH 29 Oral Infection Control Flashcards
The depression in the gingival tissue under the contact area between the lingual (palatal) papilla and the facial papilla.
The Col
V-Shaped spillway space next to the contact area of adjacent teeth, narrowest at the contact and widening toward the facial, lingual (palatal) and occlusal contacts
Embrassure
A cleft in the gingival margin usually at a mesial or distal line angle of a tooth where dental floss was repeatedly applied incorrectly. The lining of the cleft can be completely lined with epithelium.
Floss Cleft
The use of forced intermittent or steady stream of water for a cleansing or therapeutic purpose
Hydrotherapy
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
Irrigation
The point of the delivery of the irrigation is placed in the sulcus or pocket and may reach the base of the pocket depending on its probing depth
Subgingival Irrigation
Most gingival disease starts in the?
Col Area
An area is inaccessible for ordinary toothbrushing; microorganisms are harbored in the concave center
Col
Types of Gingival Embrassure:
Interdental papilla fills the gingival embrassure?
Type 1
Types of Gingival Embrassure:
With slight-to-moderate recession of the interdental papilla?
Type 2
Types of Gingival Embrassure:
With extensive recession or complete loss of the interdental papilla?
Type 3
What type of floss is good for type 2 embrassures?
Tufted Dental Floss (Super Floss)
T/F Research has SHOWN NO DIFFERENCE in the effectiveness of waxed or unwaxed floss for biofilm removal. Effectiveness depends on how the floss is applied.
True
When to floss?
Best results can be obtained by using floss before brushing
T/F Wax floss gives strength and durability and can minimize breakage
True
A sharper, then edge requires special attention to prevent injury to the gingival tissue?
- Thinner Floss
- Forcing may break the floss
- made of NYLON FIBERS
Unwaxed Floss
Also called floss/yarn combation
Tufted dental Floss/Super dental floss
Aids for flossing?
- Floss holder
- Floss Threader
- Knitting Yarn
- Gauze Strip
Used for pts with disabilities?
Floss holder
Used for Ortho, and under partial dentures or bridges?
Floss threader
Used for diastema, distal surfaces of distal teeth, isolated teeth, or wide inter-proximal spaces?
Knitting Yarn
Used on abutments, surfaces next to edentulous areas, or widely spaced teeth?
Gauze Strip
Used for type 3 embrassures?
(Interdental brushes) Proxy brush
T/F In pts with open embrasures and moderate to serve attachment loss, the interdental brush is more effective than floss
True
Purpose of oral irrigation?
to reduce the bacteria and inflammatory mediators that lead to perio infection
Benefits of oral irrigation?
- Reduces gingivitis/bleeding
- Alteration of subgingival biofilm
- Subgingival delivery of antimicrobial agents
The targeted application of a pulsated or steady stream of water or other irrigant for preventative or theraperutic purposes?
Oral irrigation
End-Tufted brush (single-tuft brush) used for?
- ortho
- implant abutment
- difficult reach areas
- fixed dental prostheses
- open interproximal areas
- sulcular brushing stroke
What is used for cleaning debris from the interdental area and removing biofilm by rubbing the exposed tooth surface (just below the gingival margin)?
Interdental tip
What is used for pts with periodontitis, for biofilm removal at and just under the gingival margin, for interdental cleaning and exposed furcations?
Toothpick in holder
Exposed proximal surfaces where interdental gingival is missing, cannot exposed root concavities , difficult to use in posterior area and lingual aspects of teeth. Need to soften tip with saliva before use. Is what type of aid?
Wooden interdental cleaner
Nylon filaments twisted into a fine stainless steel wire, can get plastic coated wires?
Interdental brushes
Used for Class IV furcations Perio Splints Space maintainers Ortho Dental implants
Interdental Brushes
The incidence of gingivitis is greatest in the?
Interdental tissues
