False
A patient with excellent periodontal treatment results has been well maintained the first year after treatment has no complicating favored and good oral hygiene may require only one maintenance recall appointment per year
True
Immediate evaluation does not include an assessment of the gingival respond to deposit removal because the tissues haven’t had time to respond so you must wait for the follow up evaluation
True
According to Wilkins the purpose of a maintenance program is the removal of any deposits missed during initial therapy
False
Patients with extensive restorative treatment like crowns, bridges and implants require less frequent recall maintenance appointments because restore surface accumulate less calculus

A patient presenting with no deposits, including no biofilm and yet there are signs of gingival inflammation may not be removing the biofilm completely on a regular basis
True
During follow up evaluation it is important to evaluate how the patient performs plaque removal and how effective it is
True
Digital video imaging done with intraoral wand is not as valuable during patient education as using typhodont to identify locations needing better biofilm removal
False
An extrinsic dental stain is one which is on the outer surface therefor is of an exogenous source and can be removed by mechanical means
True
Intro oral photographs can be used for comparison between pre treatment and post treatment
True
Immediate evaluation includes an assessment of the gingival response to deposit removal
False
Assessment data must be looked at as a whole, synthesizing and correlating the information to create a treatment plan
True
Exploratory or assessment strokes should be done intermittently between each scaling and root planning stroke
True
Mottled enamel (fluorosis) will not occur with topical fluoride applications
True
The abutment tooth is the natural tooth remaining or implant which supports a prosthetic
True
When cleaning a denture you should hold it carefully by the border so that all surfaces can be cleaned
False
In the ccp dental hygiene clinic, the agreement and consent are aofned by the patient after the treatment plan has been completely written and signed by an instructor
False
Removable spoil and should be kept in water or cleaning solution when not in patients mouth because the applicable may distort
True
The first thing you do after receiving a removable prosthetic from a patient is place it in a sterile beaker clean it in the ultrasonic bath to remove all debris the examine it for defects
False
One client care evaluation form is used during all of the treatment from the first appointment to the last
True
If there is stain or calculus on a dentures impression surface the hygienist does not scale it off
True
Parents should use full strength household bleach to clean their removable dentures and partials if there is stain on them
False
An advantage of fluoride varnish is that it does not require a completely dry environment for application
True
During polishing with rotary rubber cup, the rubber cup should be placed at a 45 degree angle to the tooth surface
False
Gross scaling should be done at the first appointment and fine scaling / root planning done during subsequence appointments so compete refinement can be accomplished
False
The sickle scalers have an advantage over curets because they can remove deposits close to the contacts between teeth
True
The primary objective of scaling and root planning is to smooth the tooth so it is esthetically acceptable
False
The 13/14 Columbia curet is a true universal in that it can be used anywhere in the mouth on any surface in any depth of pocket to remove any kind of calculus
False
Exploratory/ assessment strokes should be done intermittently between each scaling stroke and root planning stroke
True
To identify the universal curets cutting edge to be used for scaling you hold the terminal shank perpendicular to the floor
False
Channeling/ channel scaling means you engage a small segment of a calculus deposit with each working stroke to remove it not trying to remove a whole deposit with one stroke
True
Root planning strokes begin like scaling strokes and the progressively become longer strokes with lighter lateral pressure until the surface is smooth
True
Flies as a scaling instrument are used to help crush and fragment especially tenacious calculus deposits so sickles and curets are not needed
False
To remove calculus deposit from interproximal surfaces begin your scaling strokes directly apical to the contact and move to the base of the interproximal pocket
False
On external surface of tooth
- May be removed by mechanical means (tooth brushing, scaling, ultrasonic, polishing)
- always exogenous
Extrinsic stain
Occur within tooth surface
- can not be removed by mechanical means
- May be exogenous or endogenous
Intrinsic stain
Come from sources outside of the tooth
- develop after tooth eruption
- May remain extrinsic or become intrinsic
Exogenous
Originates within the tooth substances
-always intrinsic
Endogenous
Chromosome bacteria or fungi
- do not scale; underlying demineralization may be present
- brush away
Green stain

- recurrent
- scale/polish off
Black stain
Light brown to leathery black brown

True
Angulation greater than 90 degrees
One cutting edge will be in contact with the soft tissue lining
Angulation less than 45 degrees
The cutting edge will slide over the calculus deposit rather than biting in to it
The face to root surface angulation for root debridement is an angle between
60-70 degrees
For calculus removal the face to tooth surface angulation is an angle between
45-90 degrees
- calculus removal= closer to 70 degrees
- root planning= a little more than 45 degrees
Calculus removal stroke
Biting stroke
Shaving stroke made with light pressure with the cutting edge against the tooth cementum
-slightly longer than a calculus stroke
Root debridement stroke
When sharpening point tip or toe I instrument toward self and face parallel to the floor T or F
