ANSWERS

 

121. Ans: b. Middle third face

Exp: Basal-cell carcinoma most commonly occurs in men in the fifth to seventh decades of life. The area of the lesion is usually one that has frequent exposure to the sun: the middle third of the face and upper lip.

 

122. Ans: a. When a facing is demanded for cosmetic reasons

6Exp: Fused porcelain is recognized as a restorative material that is compatible with oral soft tissues plus it has superior esthetic qualities. With the use of albuminous porcelains the strength has been increased and the incidence of porcelain fractures has been reduced greater. Crowns constructed albuminous porcelain cores or occluding surfaces are incapable of replacing veneered crowns in advanced situations.

 

123. Ans: c. Erosion of teeth.

Exp: Because of hyperacidity and chronic vomiting

 

124. Ans: c. Fracture middle cranial fossa.

Exp: Battle's sign, also mastoid ecchymosis ecchymosis, is an indication of fracture of the base of the posterior portion of the skull and may suggest underlying brain trauma. It consists of bruising immediately behind the ears. Another common bruising sign of a skull injury is raccoon eyes, the purplish discoloration around the eyes following fracture of the frontal portion of the skull base. This sign is named after William Henry Battle.

 

125. Ans: d. All of the above

Exp: And even if, the blood volume is constant, and blood loss is absent any case of anemia can only be explained by decreased production of erythroid precursors or increased destruction. Both processes seem to be operating in renal failure.

 

126. Ans: b. When iridioplatium wire in the form of a staple is used for reinforcement

Exp: The full veneer crown may be placed on any tooth that cannot be returned by alternate methods to an effective bridge abutment when the caries index, torque, leverage, or load contraindicates the partial veneer crown, the pinledge, or the inlay.

 

127. Ans: d. Fixed partial denture, rem .removable partial denture, ovable complete denture

Exp: After a thorough analysis of the patients problem the form of the appliance is considered. The appliance must correct the problem. The analytical process should show the directions and the distances sought in any tooth movements. The limiting factors include those inherent in the appliance, the patient, and the operator.

 

128. Ans: b. Patient with acute respiratory infection

Exp: Indications and Contraindications for the Use of General Anesthesia and Sedation in Children, Adults, and the Geriatric Population The decision to use a particular technique in a certain age group is based on the following: Adults General anesthesia for healthy (ASA class I or II) patients may be indicated when there is greater complexity of the procedure, higher levels of preoperative anxiety, or a greater need for a painfree operative period. A contraindication to local anesthesia might also require that a general anesthetic be administered. General anesthesia is contraindicated in patients who are not healthy (ASA class III or IV) for example any acute respiratory infection Geriatric Patients The indications for use of sedation or general anesthesia for the geriatric patient are basically the same as for other adults. Contraindica Contraindications tions to the use of sedation or general anesthesia for older patients are based almost entirely on the nature and severity of such risk factors Pediatric Patients The dentist's need for a cooperative and quiescent patient for the rendering of high-quality care is a prime indication for the use of sedation or general anesthesia in some children. These modalities tend to reduce fear and anxiety and assist the uncooperative child to accept and continue to receive regular dental care. Pediatric patients with extensive and complicated treatment needs, with acute pain and/or trauma, as well as those who are physically disabled or mentally retarded, may require sedation or general anesthesia. At times, the very young child (up to 3 years of age) and those with limited or compromised ability to comprehend and communicate also are candidates for such procedures. Additionally, there may be an indication for sedation or general anesthesia when the child would be better served by increasing the length of the appointment time and thus reducing the number of visits to accomplish the required treatment. Although the presence of a severe, compromising medical condition is generally a contraindication to sedation, some patients in this category may benefit from its use. These children should be managed in close cooperation with the physician involved in their medical care. While not necessarily contraindicated in the dental office, general anesthesia in the very young child often is best managed in the hospital or a similar setting, especially for lengthy restorative procedures. In all children, severe, compromising medical conditions contraindicate general anesthesia in the dental office.

 

129. Ans: d. All of the above

Exp: When carving in inlay pattern directly, the operator muses a circular matrix band fitted loosely around the tooth, the band being trimmed both occlusally and cervically to accommodate the opposing cusps and avoid cutting the soft tissues.

 

130. Ans: d. Cleft palate

Exp: Marfan syndrome is an autosomal dominant genetic disorder of the connective tissue characterized by disproportionately long limbs, long thin fingers, a typically tall stature, and a predisposition to cardiovascular abnormalities, specifically those affecting the heart valves and aorta. The disorder may also affect numerous other structures and organs — including the lungs, eyes, dural sac surrounding the spinal cord, and hard palate.
