Periodontal Instruments Flashcards
(23 cards)
Used in the anterior region to remove supragingival calculus deposits
anterior sickle scaler
Can anterior sickle scaler go sub G?
NO; pointed toe more likely to injure tissue
When adapting the anterior sickle scaler, how should the shank and handle be oriented?
parallel to the long axis of the tooth
When adapting an instrument, what part is in contact with the teeth?
the tip, terminal 1/3
What is proper angulation for the anterior sickle scaler? What will result if you have over/under angulation?
45-90 degrees; burnished calculus for both, tissue laceration for over angulation
When do you sit for surfaces towards you for anterior teeth?
Away from you?
What is the exception?
- toward = 8 o’clock
- away = 11-12 o’clock
- exception = facial surfaces of maxillary anteriors
Where is the posterior sickle scaler used?
interproximal regions of posterior teeth, both supra- and subgingival
(not designed for scaling deep periodontal pockets)
Correct orientation for posterior sickle scaler?
terminal shank parallel to the long axis of the tooth
Do you scale the buccal and lingual surfaces with posterior sickle scaler?
NO
What is the name for the periodontal explorer?
ODU 11-12
Uses of periodontal explorer.
- to detect subG calculus and tooth irregularities
- allows clinician to assess the amount of calculus prior to removal
- used to evaluate root surfaces following calculus removal
What is the correct working end of the periodontal explorer?
tip “curves” towards the mesial of the tooth
Do you flip explorer for distal surfaces?
no, you offset
Universal curette for posterior teeth, short terminal shank.
Columbia 13/14
Universal curette for posterior teeth, long terminal shank (used for deep pockets).
4R/4L
Universal curette for with smoother curving shank. (maybe for anteriors?)
McCall’s 17/18
Where can universal curettes be used?
all surfaces of all teeth! (universal)
What is the ideal stroke for using a universal curette across a tooth surface (especially direct buccal/lingual)
oblique and overlapping
Perio probe is most important instrument for what?
assessing and diagnosing periodontitis
A Nabers probe is used to?
evaluate the bone support in the furcation areas of bifurcated and trifurcated teeth
What probe is in the perio kit at UMKC SoD? What is the other one?
Marquis probe (markings every 3mm); UNC-12 (markings every 1mm)
What is the exception for perio probe being parallel to long axis of tooth?
interproximal space due to gingival col
6 sites probing depths are recorded.
If there are multiple depths within a region, which is recorded?
- DF, F, MF, DL, L, ML
- deepest reading obtained is recorded
