    Dry socket:

    • Results from loss of blood clot in socket

    • Is treated by reinducing bleeding in socket

    • Is a form of osteomyelitis

    • Is common in extraction of anterior teeth

    Correct Answer
    A. Results from loss of blood clot in socket
    Explanation
    Dry socket occurs when the blood clot that forms after a tooth extraction is dislodged or dissolves, leaving the socket exposed. This can happen due to various reasons such as smoking, rinsing vigorously, or poor oral hygiene. When the blood clot is lost, the underlying bone and nerve endings are exposed, causing severe pain and discomfort. The treatment for dry socket involves reinducing bleeding in the socket to promote the formation of a new blood clot and alleviate symptoms.

    The precipitating factors of epilepsy are all, except

    • Hyperglycemia

    • Severe pain

    • Alcoholic drinks

    • Severe stress

    Correct Answer
    A. Hyperglycemia
    Explanation
    Hyperglycemia is not a precipitating factor of epilepsy. Epilepsy is a neurological disorder characterized by recurrent seizures, which are caused by abnormal electrical activity in the brain. While severe pain, alcoholic drinks, and severe stress can trigger seizures in individuals with epilepsy, hyperglycemia, or high blood sugar levels, is not known to be a precipitating factor. Hyperglycemia is more commonly associated with diabetes and can lead to various complications, but it is not directly linked to the onset of epilepsy.

    The third phase of epileptic seizure consists of all, except

    • Eye bleeding

    • Weakness

    • Pallor

    • Disturbances of the consciousness state

    Correct Answer
    A. Eye bleeding
    Explanation
    Eye bleeding is not a symptom or characteristic of the third phase of an epileptic seizure. The third phase typically includes symptoms such as weakness, pallor, and disturbances of the consciousness state. Eye bleeding is not associated with epileptic seizures and is therefore not a part of the third phase.

    Anaphylaxis may present with all, except

    • Hair falling

    • Hoarseness of voice

    • Dysphagia

    • Anxiety

    Correct Answer
    A. Hair falling
    Explanation
    Anaphylaxis is a severe allergic reaction that can cause a range of symptoms, including difficulty breathing, low blood pressure, hives, and swelling. Hair falling is not a typical symptom of anaphylaxis. However, hoarseness of voice, dysphagia (difficulty swallowing), and anxiety are commonly associated with anaphylaxis due to the swelling and constriction of the airways.

    Frequent site for occurrence of ameloblastoma is:

    • Mandibular molar and ramus area

    • Mandibular premolar area

    • Max molar area

    • Max antrum and floor of nose

    Correct Answer
    A. Mandibular molar and ramus area
    Explanation
    Ameloblastoma is a benign tumor that arises from the cells that form tooth enamel. It most commonly occurs in the mandibular molar and ramus area, which refers to the lower back part of the jaw. This is because the cells that give rise to ameloblastoma are derived from the dental lamina, which is present in this area during tooth development. Ameloblastoma can also occur in other areas such as the maxillary molar area, but the mandibular molar and ramus area is the most frequent site of occurrence.

    What is the time to administer analgesic for controlling postoperative pain?

    • Before the anesthetic effect wears off

    • After the regain of sensation

    • Pain becomes moderate to severe

    • During procedure

    Correct Answer
    A. Before the anesthetic effect wears off
    Explanation
    Administering analgesic before the anesthetic effect wears off is the correct answer because it ensures that the patient does not experience pain as the anesthesia wears off. By giving the analgesic before the anesthetic effect wears off, the patient's pain can be effectively controlled and managed. Waiting until the pain becomes moderate to severe or after the regain of sensation may result in the patient experiencing unnecessary pain and discomfort. Similarly, administering analgesic during the procedure may not provide adequate pain relief postoperatively.

    Among the following which is strongest stimulator to increase the respiration:

    • Increase in arterial CO2

    • Decrease IV oxygen

    • Increase blood pH

    • Increase in arterial oxygen

    Correct Answer
    A. Increase in arterial CO2
    Explanation
    Increase in arterial CO2 is the strongest stimulator to increase respiration because it acts as a respiratory drive. When CO2 levels in the blood increase, it triggers the respiratory centers in the brain to increase the rate and depth of breathing. This is known as the hypercapnic drive and is a powerful mechanism to ensure that excess CO2 is eliminated from the body. In contrast, a decrease in arterial oxygen or an increase in blood pH do not directly stimulate respiration as strongly as an increase in arterial CO2.

    All are infectious diseases, except

    • Diabetes

    • Hepatitis B

    • Hepatitis C

    • AIDS

    Correct Answer
    A. Diabetes
    Explanation
    Diabetes is not an infectious disease, but a metabolic disorder characterized by high blood sugar levels. It is caused by a combination of genetic and environmental factors, and it is not transmitted from person to person like infectious diseases such as Hepatitis B, Hepatitis C, and AIDS. Diabetes is primarily a result of the body's inability to produce or effectively use insulin, a hormone that regulates blood sugar levels.

    When a forcep is to be utilized for removal of tooth, the 1st direction for tooth to be applied is:

    • Apically

    • Occlusally

    • Buccally

    • Lingually

    Correct Answer
    A. Apically
    Explanation
    When a forcep is used for the removal of a tooth, the first direction in which the forcep should be applied is apically. This means that the forcep should be positioned towards the apex or root of the tooth. Applying force apically helps to loosen the tooth from its socket and allows for easier extraction.

    Contributory factor to pericoronitis of an impacted mandibular 3rd molar is:

    • Streptococci and bacterial infection

    • Previous radiation therapy

    • Systemic disease

    • Infected follicular cyst

    Correct Answer
    A. Streptococci and bacterial infection
    Explanation
    The presence of Streptococci and bacterial infection is a contributing factor to pericoronitis of an impacted mandibular 3rd molar. Pericoronitis is an inflammatory condition that occurs when the gum tissue around a partially erupted tooth becomes infected. Streptococci and other bacteria can enter the area and cause an infection, leading to symptoms such as pain, swelling, and difficulty in opening the mouth. Therefore, the presence of these bacteria is a significant factor in the development of pericoronitis.

    While extracting maxillary 1st molar root is displaced into maxillary sinus, management is:

    • Raise a flap and create a window in canine fossa to remove the root

    • Leave it

    • Retrieve through socket

    • Ask patient to blow nose

    Correct Answer
    A. Raise a flap and create a window in canine fossa to remove the root
    Explanation
    When a maxillary 1st molar root is displaced into the maxillary sinus, the most appropriate management is to raise a flap and create a window in the canine fossa to remove the root. This approach allows direct access to the root, ensuring its complete removal and minimizing the risk of complications such as infection or sinusitis. Leaving the root in the sinus or attempting to retrieve it through the socket may not be effective or safe. Asking the patient to blow their nose is unlikely to dislodge the root and is not a recommended management strategy in this situation.

    Rate this question:

  • 23. 

    Which of the following is the most appropriate initial treatment for a patient presenting with an odontogenic infection causing significant facial swelling and difficulty breathing?

    • Incision and drainage under local anesthesia

    • Prescribing oral antibiotics and scheduling follow-up 

    • Immediate administration of intravenous antibiotics and securing the airway 

    • Extraction of the affected tooth under general anesthesia

    Correct Answer
    A. Immediate administration of intravenous antibiotics and securing the airway 
    Explanation
    A. Incision and drainage under local anesthesia: While important, this may not be the immediate first step if the patient is experiencing difficulty breathing.
    B. Prescribing oral antibiotics and scheduling follow-up: This approach is insufficient for a severe infection causing significant swelling and airway compromise.
    C. Immediate administration of intravenous antibiotics and securing the airway: This is the correct answer. In cases of severe odontogenic infection with facial swelling and difficulty breathing, prompt intravenous antibiotics are essential, and securing the airway takes priority to prevent respiratory failure.
    D. Extraction of the affected tooth under general anesthesia: While extraction might be necessary eventually, immediate treatment should focus on managing the infection and airway.

    The first phase of epileptic seizure lasts

    • A few seconds

    • 3 to 5 minutes

    • 2 minutes

    • More than 5 minutes

    Correct Answer
    A. A few seconds
    Explanation
    During the first phase of an epileptic seizure, the duration typically lasts only a few seconds. This is because the initial phase, known as the aura, is characterized by a brief alteration in sensation or perception. It is a warning sign that the seizure is about to occur and is usually very short-lived. The subsequent phases of the seizure may last longer, but the first phase itself is typically brief.

    • Semi-impacted teeth

    • Teeth with ankylosed roots

    • Teeth with dilaceration of root tips

    Correct Answer
    A. Teeth with very deep caries
    Explanation
    Surgical tooth extraction is typically required for teeth that cannot be easily removed using simple extraction techniques. Teeth with very deep caries, semi-impacted teeth, teeth with ankylosed roots, and teeth with dilaceration of root tips are all indications for surgical extraction. However, teeth with very deep caries can often be treated with other dental procedures such as root canal therapy or dental crowns, making them an exception to the need for surgical extraction.

    One step that does not belong to the steps of surgical extraction of tooth is

    • Controlling the patient’s anxiety

    • Creation of flap

    • Removal of bone

    • Extraction of tooth

    Correct Answer
    A. Controlling the patient’s anxiety
    Explanation
    Controlling the patient's anxiety is not a step in the surgical extraction of a tooth. While it is important to ensure that the patient is calm and comfortable during the procedure, it is not a specific step in the extraction process itself. The steps involved in surgical extraction typically include creating a flap to access the tooth, removing any surrounding bone if necessary, and then extracting the tooth from its socket.

    Hypoglycemia may occur in patient taking insulin and undergoing extraction when?

    • Extraction is done on empty stomach

    • Patient had infection

    • Patient had no exercise in morning

    • Patient had breakfast before extraction

    Correct Answer
    A. Extraction is done on empty stomach
    Explanation
    Hypoglycemia may occur in a patient taking insulin and undergoing extraction when the extraction is done on an empty stomach. When a patient takes insulin and does not eat, their blood sugar levels can drop too low, leading to hypoglycemia. Therefore, if extraction is performed on an empty stomach, there is a higher risk of hypoglycemia occurring in these patients.

    After surgery of 3rd molar, patches of anesthesia on chin is due to damage of:

    • Inferior alveolar nerve

    • Lingual nerve

    • Mental nerve

    • Mylohyoid nerve

    Correct Answer
    A. Inferior alveolar nerve
    Explanation
    The patches of anesthesia on the chin after surgery of the 3rd molar are due to damage of the inferior alveolar nerve. The inferior alveolar nerve is responsible for providing sensation to the lower teeth, chin, and lower lip. Damage to this nerve can result in numbness or loss of sensation in these areas.

    The bone cysts that are less than 2 cm in diameter can be treated by:

    • Enucleation

    • Marsupialization

    • No-treatment

    • None of All

    Correct Answer
    A. Enucleation
    Explanation
    Bone cysts that are less than 2 cm in diameter can be treated by enucleation. Enucleation is a surgical procedure where the cyst is removed from the bone. This treatment option is suitable for smaller cysts as it helps to prevent further growth and potential complications. Marsupialization, on the other hand, involves creating a small opening in the cyst to drain and decompress it, but it is not recommended for cysts smaller than 2 cm. No-treatment is not a suitable option as it can lead to further growth and potential complications. Therefore, enucleation is the correct answer.

    The preferred position for the patients with congestive heart failure is

    • Sitting position

    • Standing position

    • Sleeping position

    • Sleeping position with legs raised a bit upward

    Correct Answer
    A. Sitting position
    Explanation
    The preferred position for patients with congestive heart failure is the sitting position. This is because sitting upright helps to reduce the workload on the heart by promoting better blood flow and reducing fluid buildup in the lungs. It also helps to alleviate symptoms such as shortness of breath and swelling in the lower extremities. Additionally, sitting allows for better monitoring of vital signs and easier access for medical interventions if needed.

    Angina Pectoris

    • Is characterized by the temporary ischemia in part of or all of the myocardium.

    • Is the inability of the myocardium to pump enough blood to satisfy the body.

    • Is the ischemic necrosis of an area of the heart.

    • Is any periodic variation in the normal rhythm of heart.

    Correct Answer
    A. Is characterized by the temporary ischemia in part of or all of the myocardium.
    Explanation
    Angina Pectoris is characterized by the temporary ischemia in part of or all of the myocardium. This means that during an episode of angina, there is a temporary reduction in blood flow to the heart muscle, leading to chest pain or discomfort. The reduced blood flow is usually caused by the narrowing or blockage of the coronary arteries, which supply oxygen-rich blood to the heart. This temporary ischemia can result in symptoms such as chest pain, shortness of breath, and a feeling of tightness or pressure in the chest.

  • 35. 

    All are true about hypertension, except

    • Patients with hypertension should never undergo surgical procedure

    • Essential hypertension does not have any known causes

    • Secondary hypertension has known causes

    • Hypertension is the abnormal elevation of the arterial pressure above the aforementioned values

    Correct Answer
    A. Patients with hypertension should never undergo surgical procedure
    Explanation
    The given statement is incorrect. Patients with hypertension can undergo surgical procedures, but it is important for their blood pressure to be well controlled before the surgery to minimize the risks. Surgery itself does not cause hypertension, but certain factors during the procedure such as stress, anesthesia, and fluid shifts can temporarily increase blood pressure. Therefore, it is crucial for patients with hypertension to work closely with their healthcare provider to manage their blood pressure before and after surgery.

    Rate this question:

  • 36. 

    All are the preventive measures of the patients with hypertension before dental procedure, except

    • Blood pressure should be monitored after, not before the surgery

    • Premedication

    • Short appointments

    • Avoidance of noradrenaline in patients receiving anti-hypertensive agents

    Correct Answer
    A. Blood pressure should be monitored after, not before the surgery
    Explanation
    Monitoring blood pressure after surgery is not a preventive measure for patients with hypertension before a dental procedure. It is important to monitor blood pressure before the surgery to ensure that it is within a safe range for the patient. This helps to identify any potential risks or complications that may arise during the procedure. The other options mentioned - premedication, short appointments, and avoidance of noradrenaline in patients receiving anti-hypertensive agents - are all valid preventive measures to manage hypertension during dental procedures.

    Allergy that is caused by the use of local anesthetics is usually due to

    • Preservatives in the ampoule

    • Amount of adrenaline

    • Amount of noradrenaline

    • Expired anesthetics

    Correct Answer
    A. Preservatives in the ampoule
    Explanation
    An allergy caused by the use of local anesthetics is usually due to the presence of preservatives in the ampoule. These preservatives can trigger an allergic reaction in some individuals. Adrenaline and noradrenaline are not typically the cause of the allergy, and expired anesthetics may lose their effectiveness but are not necessarily the cause of an allergic reaction. Therefore, the presence of preservatives in the ampoule is the most likely explanation for the allergy.

    What can you do after tooth extraction by surgery?

    • Rinse your mouth gently

    • Avoid spitting for about 2 weeks

    • Brush your teeth which are adjacent to the extraction site excessively

    • You can touch the extraction site with your tongue but not fingers

    Correct Answer
    A. Rinse your mouth gently
    Explanation
    After tooth extraction by surgery, it is important to rinse your mouth gently to keep the area clean and prevent infection. This helps to remove any food particles or debris that may be present. However, it is advised to avoid spitting for about 2 weeks to prevent dislodging the blood clot that forms in the extraction site. Excessive brushing of the teeth adjacent to the extraction site should be avoided as it may cause irritation or damage to the healing area. It is acceptable to touch the extraction site with the tongue, but not with fingers, to assess the healing progress.

    A. Teeth of old patients
    Explanation
    The indications for surgical tooth extraction include teeth with unusual roots, teeth with hypercementosis of roots, and impacted teeth. However, the age of the patient is not a factor in determining whether a surgical tooth extraction is necessary. Therefore, teeth of old patients are not an indication for surgical tooth extraction.

    Which one is not the basic principle of suturing technique?

    • Tie the sutures very tightly to avoid ischemia of the wound edge

    • Insert the needle at right angles to the tissue

    • The exit tract should likewise be at right angles to the tissue

    • Sutures should be placed at right angles to the line of the wound

    Correct Answer
    A. Tie the sutures very tightly to avoid ischemia of the wound edge
    Explanation
    The correct answer is "Tie the sutures very tightly to avoid ischemia of the wound edge." This is not a basic principle of suturing technique because tying the sutures too tightly can lead to ischemia, which is the restriction of blood supply to the wound edge. It is important to tie the sutures with appropriate tension to ensure proper healing and blood flow to the wound.

    A male is taking 60 mg of hydrocortisone daily on day of extraction the dose should be:

    • Double

    • Remain unchanged

    • Reduced to ½

    • Reduced to ¼

    Correct Answer
    A. Double
    Explanation
    When a patient is taking hydrocortisone, it is important to consider the stress of a dental extraction. During times of stress, the body's demand for cortisol increases. Hydrocortisone is a synthetic form of cortisol, so increasing the dose during times of stress is necessary to meet the body's demand. Therefore, the correct answer is to double the dose of hydrocortisone on the day of extraction.

    An absolute contraindication for extraction of teeth is:

    • MI after 4 months

    • Hypertension

    • Hypotension

    • Thyrotoxicosis

    Correct Answer
    A. MI after 4 months
    Explanation
    Extraction of teeth is contraindicated in patients who have experienced a myocardial infarction (MI) within the past 4 months. This is because the healing process after an MI takes time, and any stress or trauma to the body, such as tooth extraction, can potentially worsen the condition or cause complications. It is important to ensure that the patient's cardiovascular health is stable before performing any invasive procedures like tooth extraction.

    Extraction of a tooth during acute infection:

    • Helps drainage and relieves pain if proper AB is given and its adequate blood level is reached

    • Can cause extensive spread of infection

    • Can cause sudden death due to pulmonary embolism

    • Can lead to trigeminal neuralgia in postoperative of period

    Correct Answer
    A. Helps drainage and relieves pain if proper AB is given and its adequate blood level is reached
    Explanation
    Extraction of a tooth during acute infection helps drainage and relieves pain if proper antibiotic (AB) is given and its adequate blood level is reached. This is because the extraction removes the source of infection, allowing for better drainage and reducing pain. Additionally, the use of antibiotics helps to control the infection and prevent further spread. However, it is important to ensure that the proper antibiotic is given and that it reaches an adequate blood level to effectively treat the infection.

    Most important principle during extraction:

    • Least trauma bone and mucosa while extracting whole tooth out

    • Least trauma to bone while extracting whole tooth out

    • Least trauma to mucosa while extracting whole tooth out

    • None of All

    Correct Answer
    A. Least trauma bone and mucosa while extracting whole tooth out
    Explanation
    The most important principle during extraction is to minimize trauma to both the bone and the mucosa while removing the entire tooth. This ensures that the surrounding tissues are preserved and the healing process is facilitated. By minimizing trauma to both the bone and the mucosa, the extraction procedure can be performed more efficiently and with less post-operative complications.
