Pre-Clinic Theory Exam 2
1. What is an explorer used for?: - calculus detection
- detection/assessment of:
- grooves
- curvatures
- root furcations
- dental restorations
- sealants
- defective restorations
- surface irregularities
- root caries
2. What methods are used for detecting calculus?: - exploring
- radiographs
- detectar
- perioscope
- direct vision
- clinical evaluation
3. Why is it important to accurately detect calculus?: - Discover cause for disease
, Pre-Clinic Theory Exam 2
- Determine needed treatment
-Determine time needed to complete treatment
-Evaluate completeness of treatment
-Determine difficulty while in school
-Find regional dental hygiene board patient
4. When should you use the explorer?: -Before creating a tx plan
-Explore, scale, explore
-After finding out there is residual calculus remaining
-Scale check
- Re-eval appointment
-Finding a board patient
5. What are the specific design characteristics of an 11/12 explorer?: - Flexible working end
- Paired working ends
- Tapers to a sharp point
- Tip is at a 90 degree angle to lower shank
- Long complex shank
- Circular cross section
, Pre-Clinic Theory Exam 2
6. Tip of explorer: -1 to 2 mm of the SIDE of the explorer
- adapted to the tooth for detection of calculus deposits
7. Lower shank of the explorer: - The lower shank of an explorer is the section of the shank that is
nearest to the explorer tip
8. Caries detection with an explorer: If the explorer sticks or tugs back on with- drawal, then
caries are present
9. Is the caries detection method with an explorer recommended?: NO
- may rupture remineralization process
- Research has proven it is unreliable
10.What is the handle of the explorer like?: - Lightweight
- Less pressure to hold instrument
- Big handle
- able to use light pressure with grasp
11.An explorer can detect calculus through direct vision, sound, and tactile sensitivity. T/F:
TRUE
12.What is tactile sensitivity?: the ability to detect calculus deposits by feeling vibrations
transferred from the explorer tip to the instrument shank and handle
, Pre-Clinic Theory Exam 2
13.Tactile sensitivity process: 1.) The explorer tip quivers as it passes over a calculus deposit on
the root of the tooth
2.) These vibrations are transmitted from the tip through the instrument shank and handle
3.) The clinician feels these vibrations with his or her fingers resting on the instrument shank and
handle
4.) The clinician recognizes these vibrations as calculus deposits
14.Auditory and visual of the explorer: - Quiet
- clean, smooth enamel
-Audible
-Calculus, restorations
- Visual "jump" with explorer
15.Grasp with exploring: - relaxed grasp, very light pressure
- middle finger rests lightly on shank
16.Adaptation with an explorer: 1-2 mm of side of tip
