Periodontology
1. the reasons for performing soft tissue curettage;
(a) shallow, edematous pockets
(c) pockets in patients not accepting surgery
(d) presurgical preparation
(g) gingival inflammation persisting after root planning
2. A phase microscope plaque specimen taken from a patient who thoroughly cleaned his mouth each day for the previous two weeks would show high concentrations of epithelial cells and gram-positive cocci.
3. No keratinization without rete ridges are seen in the epithelial lining of the apical portion of a healthy human gingival sulcus.
Clinical DH
1. Ultrasonic scaling techniques are most effective for the removal of Supragingival calculus only.
2. An adult patient has nine mandibular teeth remaining. An isolated right second molar supports a mandibular partial denture. The tooth has heavy supragingival calculus on facial and lingual surfaces and isolated particles of subgingival calculus on the distofacial line angle. Which of the following sequences of instruments should be selected to scale and root plane this tooth?
Answer:
A heavy-bladed curette with a long shank followed by a thin-bladed curette with a long shank
3. A chisel is most effective when used for removing calculus in Facial aspect of posterior teeth.
4. working strokes is most effective and efficient for performing root planning using curettes;
Long, push strokes with the blade angled at 15-25 degrees followed by short, pull strokes with the blade angled at less than 90 degrees.
5. Root planning may be useful in
(b) reducing shallow edematous pockets to normal sulci
(d) reducing the depth of the narrow three0\-walled intrabony defect
6. Scaling should be avoided
(a) in carious lesions
(b) in areas of erosion
(c) on a porcelain margin
But not (d) in a developmental defect
7. The mesial root surface of a maxillary first premolar is particularly difficult to plane because of The deep grooving often present.
8. Take a vitalometer reading on the contra lateral tooth should be a follow-up to a vitalometer reading of 4 on a scale of 10 on a sensitive tooth.
Head & Neck Anatomy
1. Reduced enamel epithelium plays an important role in Forming the epithelial attachment.
2.The cementoenamel junction on proximal surfaces of anterior teeth is shaped Convex coronally
3. Buccinator muscles of mastication is often hypertrophied as a result of chronic bruxsim
4. A 13-year old patient with normal oral mucosa has facially inclined maxillary and mandibular incisors. This is indicative of Deviant swallowing.
Dental Material
1. Hypersensitivity to cold that develops after placement of an amalgam restoration usually indicates that Pulp hyperemia is present.
2. Model plaster or stone is sifted into the water before mixing in order to Allow the particles to become wet from the bottom to the top to drive off entrapped air from the powder.
3. Improved stone gypsum products requires the lowest water-powder ratio for standard mixes.
4. The proper method of clinically prolonging the setting time of alginate hydrocolloids is to Decrease water temperature.
Pharmacology
1. p.r.n (when necessary, according to circumstances)
2. Protracted use of sulfa drugs may produce symptoms of vitamin K deficiency because sulfa drugs inhibit growth of intestinal bacteria.
Radiology
1. Radiation film fog may be caused by secondary radiation.
2. In taking radiographs, intensifying screens are used to reduce exposure time.
3. The primary reason for using leaded aprons on patients during expose to dental x-ray procedures is to Absorb scattered radiation to the patient’s reproductive cells.
4. Receiving small amounts of x-radiation over a long time
(b) results in biological injury
(c) allows time for tissue repair
(d) increases the latent period
5. The lateral jaw film is most commonly used for observing Areas of the mandible and maxilla too large to show on a periapical film.
6. Maxillary occlusal projection is required to aid localization of an impacted maxillary premolar after disclosure by adequate periapical radiographs.
Oral Pathology
1. A child with erythroblastosis fatalis may show staining of the teeth which
(c) is the deposition of blood pigments
(d) may occur as a green or brown color
2. Lichen planus is probably associated with Nervous tension.
3. Recurrent herpes is a viral disease that is influenced by stress, causes local oral lesions and may cause a central nervous system disease.
4. Mucoceles (retention cysts) of the lower lip are usually caused by Severance of salivary ducts.
5. Malignant neoplasm’s differ from benign neoplasm’s in that malignant neoplasm’s are able to
(a) metastasize
(c) extend by direct invasion
Special Needs Pt.
1. An elderly patient with a dry mouth and enlarged parotid glands may have a related problem of Rheumatic arthritis.
