During a periodontal assessment, the hygienist records the following findings on the periodontal chart for the facial aspect of a tooth: Gingival Margin Level: -2mm Periodontal Probing depth: 9mm ?What is the clinical attachment loss for the facial surface of the tooth?
What is 7mm?
100
After thorough periodontal instrumentation, healing of the periodontal tissues will normally occur. The primary type of healing in a site of attachment loss after periodontal instrumentation is through the formation of this.
What is a long junctional epithelium?
100
When the gingival margin is coronal to the CEJ, the CAL is calculated by ____________ the gingival margin level from the probing depth.
What is subtracting?
100
This is a linear developmental depression in the root surface that may occur on the proximal surfaces of anterior and posterior teeth, as well as facial and lingual surfaces of molar teeth.
What is a root concavity?
100
This is the mechanism a powered instrument uses to fracture calculus deposits from the tooth surface.
What is rapid energy vibrations of the instrument tip?

During a periodontal assessment, the hygienist records the following findings on the periodontal chart for the facial aspect of a tooth: Gingival Margin Level: +2mm Periodontal Pocket Depth: 5mm ?What is the clinical attachment loss for the facial surface of the tooth?
What is 7mm?
200
This is the amount of time that should pass before reassessing your patient's tissue response after instrumentation.
What is one month?
200
The function of the ___________ is to keep the free gingiva from being pulled away from the tooth.
What is the attached gingiva?
200
This instrument would be most effective in removing a small-size calculus deposit located 6 mm apical to the CEJ within a very narrow periodontal pocket?
What is a Gracey curet with a miniature working end?
200
The water that exits near the tip of an ultrasonic instrument tip serves these two purposes.
What is cools the instrument tip and washes bacteria from the pocket?
300
A patient has a 6 mm loss of attachment on a mandibular first molar. The dental hygienist inserts a Nabers furcation probe into the pocket and tries to move the tip between the mesial and distal roots of the tooth. The hygienist is assessing the tooth for this.
What is furcation involvement?
300
Disease that involves the periodontal ligament, alveolar bone, and cementum.
What is periodontal disease?
300
This type of probe has a curved, blunt-tipped working end that allows easy access to the furcation area.
What is a Nabors Furcation probe?
300
A longer lower shank, a shorter working end, and a thinner working end are common characteristics of this type of curet.
What is a miniature Gracey curet?
300
The water flowing through a powered instrument tip forms tiny bubbles that collapse, producing shock waves that destroy bacteria by tearing the bacterial cell walls. This mechanism of action is termed _____.
What is cavitation?
400
A patient has a 9 mm of attachment loss on a maxillary first molar. The hygienist applies moderate alternating pressure in a facial-lingual direction against the tooth, first against the facial surface of the tooth, then from the lingual surface of the tooth. The hygienist is assessing the tooth for this.
What is horizontal tooth mobility?
400
Bacteria attach to oral surfaces and form well-organized communities known as this.
What is plaque biofilm?
400
Access to the furcation on the distal aspect of a maxillary molar is best felt from the ________ aspect.
What is the lingual aspect?
400
This instrument has a disk-shaped working end.
What is the O'Hehir?
400
When working with a powered instrument, the swirling effect produced by the water stream within the confined space of a periodontal pocket is termed _____.
What is accoustic microstreaming?
500
A patient has a 9 mm of attachment loss on a maxillary first molar. The hygienist applies moderate pressure against the occlusal surface in an upward direction. The hygienist is assessing the tooth for this.
What is vertical tooth mobility?

Marge asks her dental hygienist why it is important to remove the tartar deposits from her teeth. Calculus should be removed for this reason.
What is calculus deposits are covered by a living layer of plaque biofilm?
500
____________ are calculated from measurements made from a fixed point that does not change-the CEJ. Because the bone level in health is approximately 2mm apical to the CEJ, ____________ provide a reliable indication of the extent of bone support for a tooth.
What is clinical attachment levels?
500
This instrument has a longer lower shank with a smaller working end designed for instrumenting pockets greater than 4 mm in depth. Each is limited to use only on certain teeth and certain tooth surfaces, and in this manner is similar to a Gracey curet.
What is a Langer curet?
500
Dental aerosols have been shown to survive for up to _____.
What is 24 hours?
