3. To minimize gagging and overcome fear when making an alginate impression for a child, it is recommended to secure the madibular impression first.
4. Overheating an amalgam restoration during polishing causes;
pain to the patient
trauma to pulp tissue
the retained mercury to be drawn to the surface
5. The principle advantage of zinc oxide-eugenol cement over zinc phosphate cement is its obtundent effect on the pulp.
6. “Grit” refers to Size of abrasive particles.
7. An impression should be removed from the mouth with a quick, continuous displacing movement to minimize Permanent deformation.
8. The cement used for cementing orhodontic bands is spatulated over a large area to dissipate heart and to slow setting time.
Microbiology & Immunology
1. Herpes zoster or shingles is caused by Varicella.
2. The major function of the plasma cell is plasma cells.
3. Epstein-Barr virus is the cause of infectious mononucleosis.
4. Antimicrobial characteristics of alcohols include Inability to penetrate blood and tissue or instrument surfaces.
5. Microorganisms are most susceptible to the action of physical and chemical agents during the logarithmic phase of growth.
Fluoride
1. Enamel hypoplasia is a symptoon of chronic fluoride toxicity.
2. Approved fluoride compounds found in over-the-counter dentifrices include sodium fluoride, stannous fluoride, sodium monofluorophosphate.
3. The time it takes for plaque to drop to an acid pH after eating and the time it takes for the pH to return to normal are depended upon;
(a) plaque thickness
(b) rate of salivary flow
(c) carbohydrate substrate
4. Which of the following types and concentrations of fluoride should be recommended to a head and neck cancer patient for home-care custom tray use?
A- 0.4% stannous fluoride
B- 1% neutral sodium fluoride
(no 1.23% acidulated phosphate fluoride for this pt. )
5. Fluorapatite is the most stable reaction product of a topical application of fluoride.
6. The pH of acidulated fluoride gels is in the range of 3 to 5.
Clinical Dental Hygiene
1. The method of brushing in which bristles are angled toward the occlusal surface is designed primarily to Facilitate interdental cleaning.
2. the mode of action of solutions and pastes used as desensitizing agents;
deposition of insoluble salt in exposed dentin
stimulation of formation of secondary dentin
3. green, tobacco. metallic are exogenous extrinsic, stains that can become intrinsic stains.
4. A wooden wedge is used with a matrix band to force the band against the tooth.
5. A patient returns one week after thorough dental scaling and polishing. Gingival shrinkage has occurred and black specks are observed near the gingival margin. This most likely indicates that Old calculus is exposed.
6. The correct stroke for performing soft tissue curettage on facial and lingual surfaces is long and horizontal.
7. The sensation of touch, pain, pressure or temperature is determined by the Specific nerve fiber stimulated.
8. Hydrotherapy devices (irrigators) are considered effective for removing
A- material alba
B- large food particles
9. Definitive exploration must be used to distinguish between calculus and;
C- cemental resorption
D- an overhanging restoration
E- an irregular cementoenamel junction
10. The ultrasonic principle is based on the use of High-frequency sound waves.
11. The internal angle between the face of the blade and the lateral surface of a Gracey curet is 70-80 degrees.
Periodontology
1. Increased density of alveolar bone changes occurs in the periodontium in response to increased function
2. For new attachment to occur, which of the following conditions should be present;
complete removal of junctional and pocket epithelium
complete removal of calculus or altered cementum
an adequate number of undifferentiated mesenchymal cells
3. The most important factor in promoting wound healing after removal of a periodontal dressing is effective plaque control.
4. Spares plaque is a characteristic of juvenile periodontitis that differentiates it from chronic adult periodontitis.
5. Gingival attachment portions of the periodontium is least affected by traumatic occlusal forces.
6. Metabolism of sucrose by Streptococcus mutans results in production of;
X dextrans
X acids
7. Atrophy in papillary contour is a sign of previous infection with necrotizing ulcerative gingivitis.
Head & Neck Anatomy
1. Maxillary first premolars is most liekley to have two separate roots.
2. Sharpey’s are coarse, connective tissue fibers located in the surface of bone.
3. Rests of Malassez are composed of Groups of epithelial cells in the periodontal ligament.
4. The contractile element of skeletal muscle is the sarcoplasm.
5. Application of excessive heat to a tooth results in pain because all stimuli to the pulp result in a pain sensation.
6. Mandibular teeth are vascularized by branches of maxillary arteries.
7. Periodontal ligament transmits the senseation of contact when teeth are occluding.
Nutrition
1. Pernicious anemia is best treated with vitamin B12.
Pharmacology
1. Environmental contamination by nitrous oxide can be minimized by Employing a scavenger system.
2. Administration of pure oxygen to a patient with a depressed respiratory center can be dangerous because it may Removed the remaining stimulus for respiration.
3. A patient is given extensive doses of a broad-spectrum antibiotic. A sequela that may develop is Black hairy tongue.
4. Protacted use of sulfa drugs may produce symptoms of vitamin K deficiency because sulfa drugs inhibit growth of intestinal bacteria.
5. Orthostatic hypotension is commonly seen in patients taking diuretics or antianginal drugs.
6. A patient who takes reserpine is probably being treated for Hypertension.
Radiology
1. Which of the following cause film fog in developed radiographs?
B- scattered radiation
C- improper safelighting
D- light leak in the darkroom
Community DH
1. When dental health is neglected, it is largely because of
A- self-perception of need
B- the non-threatening nature of dental disease
Special Needs Pt
1. Dyspnea on exertion and paroxysmal nocturnal are common symptoms of Congestive heart failure.
