Dental Hygiene - Dental Hygiene 2 Test Reviews Part 2
The hydrodynamic theory explains dentinal hypersensitivity as a result of fluid movement within the dentinal tubules when exposed to stimuli like cold, heat, or touch. This fluid shift triggers nerve endings, causing sharp pain or sensitivity.
PREDISPOSING FACTORS in periodontal ABSCESS FORMATION include which of the following:
a. deep suppuration pockets, advanced periodontal infection
b. pocket extending into furcation areas or intrabony areas
c. patient susceptible to infection such as uncontrolled diabetes, with an immunodeficiency disease, or being treated with an immune-suppressible drug
d. A and C
e. all of the above
e. all of the above

Removes dental biofilm and the majority of calculus: | scaling |
Removes diseased sulcular epithelium, inflamed connective tissue: | gingival curettage |

TRUE OR FALSE | Scaling and root planing precedes gingival curettage. | True |
TRUE OR FALSE | Following gingival curettage, residual "tags" do not need to be removed. | False |
TRUE OR FALSE Number and length of appointments will be determined by the patient's tolerance level, scheduling requirements, severity and deficiency of the oral health. | True |
TRUE OR FALSE | Topical anesthetics are less concentrated than the anesthetics injected. | False |
TRUE OR FALSE | The Arkansas stone is a synthetic stone. | False |
TRUE OR FALSE | Sharpening stones cannot be autoclaved. | False |
TRUE OR FALSE | A sickle and curette have two blades to be sharpened at each end. | True |
TRUE OR FALSE | A sharp instrument minimizes the number of strokes. | True |
TRUE OR FALSE | During instrumentation, wrist and arm bear the weight during a stroke, rather than flexing the fingers in the grasp. | True |
TRUE OR FALSE | An anesthesia patch provides a deep level of anesthesia to the soft tissue. | True |
TRUE OR FALSE To remove heavy calculus requires a very secure fulcrum, lateral pressure, and short biting strokes to avoid undue damage. | True |
The steps for providing manual scaling: 1-2 | Pick up the instrument using a light modified pen grasp. | 2. Select the correct cutting edge of the instrument. |
The steps for providing manual scaling: 3-4 | Stabilize your hand in your patient's mouth using a finger rest (fulcrum). Angle the instrument blade for insertion to the base of the periodontal pocket. |
The steps for providing manual scaling: 5-6 | Apply light lateral pressure for instrument insertion and confirmation of soft tissue attachment. Adapt the toe of the cutting edge on the instrument against the tooth surface. |
The steps for providing manual scaling: 7-8 | Apply sufficient (moderate to heavy) lateral pressure for calculus removal. Activate the instrument, maintaining the angulation and adaptation of the cutting edge evenly during the stroke. |
The steps for providing manual scaling: 9-10 | Repeat overlapping, channeled strokes to remove calculus. Use smooth, overlapping, light pressured finishing strokes that provide tactile sensitivity to minute irregularities of the tooth surface. |
