Unit 4 Flashcards
A calibrated periodontal probe is marked in millimeter intervals. Each millimeter increment (from 1 to 12 mm) is indicated on the working-end of all calibrated probes.
The first statement is true; the second statement is false.
A decision by the patient to reject treatment should happen before informed consent. Informed refusal forms should be a part of patient documentation.
The first statement is false; the second statement is true.
Angela is probing the mandibular canine. In the mesial site (site 3), the measurements are 3 mm, 3 mm, and 3.5 mm. What should Angela record for the mesial site?
4 mm
Beulah has inserted a periodontal probe to the base of a sulcus. Which of the following tissues forms the base of a clinically normal gingival sulcus?
Junctional epithelium
Clyde has inserted a probe to the base of a clinically normal sulcus. Which of the following tissues does the probe touch at the base of the sulcus?
Junctional epithelium
Corbin has walked a periodontal probe across the mesial surface until it touched the contact area. What should Corbin do next?
Slant the probe slightly and gently press downward to assess beneath the contact area.
Igor is recording probing depth measurements on a periodontal chart. How many measurements should he record for each tooth?
Six
Where should probing begin on the lingual site of the mandibular left first molar?
Distolingual line angle
In a healthy sulcus, the junctional epithelium is attached to which of the following structures?
Enamel
In a periodontal pocket, the junctional epithelium is attached to which of the following structures?
Cementum
Since only light pressure is used when probing, _____ activation may be used.
either wrist or digital
A carious lesion that can be detected visually should be explored. When examining an occlusal surface, the clinician should trace the entire length of a fissure with the explorer while applying heavy pressure downward into the developmental depression.
Both statements are false
During an assessment stroke with an explorer
Wrist or digital activation is acceptable
During your assessment stroke with an explorer you would:
Overlap many strokes in multidirections
For a normal sulcus your assessment stroke extends from the sulcus base to just beneath the gingival margin. Within a pocket, explore the cervical section first.
The first statement is true; the second statement is false.
Gordon wants to select the correct working-end of an explorer for use on a molar. Which of the visual clues should he use?
Both posterior = parallel and functional shank up and over the tooth
John consistently fails to detect calculus deposits at the line angles of posterior teeth. Which of the following is the most likely cause?
Not using horizontal strokes to assess the line angle area
Mary wants to select the correct working-end of an explorer for use on a mandibular molar. Which of the following is a correct technique for selecting the working-end?
She should place the working-end on the distal surface; if the lower shank is parallel to the distal surface, this working-end is correct
One to two millimeters of the side of the explorer’s working-end is known as the _____.
explorer tip
Rolling the handle of the explorer at the line angle of a tooth helps to:
Maintain correct adaptation of the explorer
Sadie wants to improve her ability to detect calculus. Which of the following techniques will help her achieve this goal?
Lightly resting her middle finger on the shank
Subgingival calculus deposits are ____
located beneath the gingival margin
To improve calculus detection, the clinician should apply firm pressure against the tooth surface. Many overlapping strokes should be used during assessment of the root surface.
The first statement is false; the second statement is true.
When using an 11/12-type explorer on mandibular anterior teeth, the correct working-end
Curves toward the tooth surface
When using an 11/12-type explorer on maxillary anterior teeth, the correct working-end:
Curves towards the tooth surface
