MDS PREP
The lower incisors of a patient were injured four years ago. Now radiographs reveal a large radiolucent area associated with the apices of these teeth. Line of treatment is
1. Extract four incisors
2. Perform PA surgery
3. Endodontic treatment of only non-vital teeth
4. None of the above
Endodontics
Answer: 3
Endodontic therapy is said to be successful when following changes occur in periapical region
1. Formation of cementum
2. Regeneration of alveolar bone
3. Regeneration of PD ligament
4. All of the above
Endodontics
Answer: 4
When it comes to assessing the success of endodontic therapy, the changes that
occur in the periapical region are crucial indicators. A successful treatment
typically results in the formation of new cementum, regeneration of the alveolar
bone, and regeneration of the periodontal ligament. These processes are all part
of the body's natural healing response to the removal of infection and the
introduction of a biocompatible filling material in the root canal system. Thus,
all of the above factors contribute to the overall success of the treatment.
The primary reason for replacing teeth destroyed due to nursing bottle syndrome is
1) Speech and aesthetics
2) Form and function
3) Incising and mastication
4) All of the above
Pedodontics
Answer: 1
A bacterial disease with oral manifestations is
1. Herpes Measles
2. Measles
3. Diphtheria
4. Leishmaniasis
Microbiology
Answer: 4
Diphtheria serious bacterial infection that usually affects the mucous
membranes of the nose and throat.
Diphtheria signs and symptoms usually begin 2 to 5 days after a person becomes
infected. Signs and symptoms may include:
A thick, gray membrane covering the throat and tonsils
A sore throat and hoarseness
Swollen glands (enlarged lymph nodes) in the neck
Difficulty breathing or rapid breathing
Nasal discharge
Fever and chills
Tiredness
Skin (cutaneous) diphtheria
A second type of diphtheria can affect the skin, causing pain, redness and
swelling similar to other bacterial skin infections. Ulcers covered by a gray
membrane also may be a sign of skin diphtheria.
A patient with a history of liver cirrhosis develops a hemorrhagic tendency. Which coagulation factor is likely to be deficient?
1) Factor I (Fibrinogen)
2) Factor II (Prothrombin)
3) Factor V
4) Factor VIII
In liver disease, especially cirrhosis, there is a decrease in hepatic synthesis of clotting factors, particularly factor II (prothrombin). Vitamin K deficiency is also common in liver disease, which further contributes to hypoprothrombinemia. The deficiency of fibrinogen (factor I) would also result in a bleeding diathesis but is less common in liver disease. Factors V and VIII are also synthesized in the liver but are less frequently affected than factor II in such cases.
Which of the following lesions exhibits ghost cell
1) Calcifying odontogenic cyst or Gorlin cyst
2) Odontomas
3) Both the above
4) None of the above
Oral Pathology
Answer: 3
What is the main function of the cephalic phase of gastric secretion?
1) To secrete digestive enzymes
2) To increase gastric motility
3) To increase gastric acidity
4) To initiate the secretion of gastrin
E) To prepare the stomach for food intake
The cephalic phase of gastric secretion is initiated by the sight, smell, thought, or taste of food and prepares the stomach for the arrival of food by increasing gastric secretion, gastric motility, and salivation. It does not directly increase gastric acidity but does contribute to the overall digestive process.
The outcome of results of laterally positioned flap depends on
1) Presence of sufficient bone support at donor site
2) Thickness of attached gingiva at donor site
3) Width of attached gingiva at donor site
4) All of the above
Periodontics
Answer: 4
Explanation:The success of a laterally positioned flap in periodontal surgery is influenced by several factors, including the presence of sufficient bone support at the donor site, the thickness of attached gingiva at the donor site, and the width of attached gingiva at the donor site. All these factors contribute to the healing and stability of the flap.
