Baker anchorage utilizes

1) Intermaxillary anchorage with screws
2) Intramaxillary anchorage with screws
3) Intermaxillary anchorage with elastics
4) Intramaxillary anchorage with elastics

SOLUTION

Intermaxillary anchorage or Baker's Anchorage. This type of anchorage involves using elastics from one jaw to the other, in the form of either Class 2 elastics (moving upper teeth back) where lower molar teeth serve as anchors, or Class 3 elastics (moving lower teeth back) where upper molars serve as anchors.

Intramaxillary anchorage is also used in the form of E-chain, when elastics are used from the back molar teeth to the front teeth in the same jaw to move teeth back of the mouth.

Why must central and lateral incisors be splinted together when canines are replaced?
1) To prevent lateral drifting of the bridge
2) To provide additional bone support
3) To improve the aesthetic outcome
4) To balance the bite force distribution

splinting is used to distribute occlusal forces and prevent lateral drifting, which is particularly important when replacing canine teeth.

Which of the following antibiotics shows an incidence of approximately 8% cross-allergencity with penicillins?

1)  Bacitracin     
2)  Erythromycin
3)  Cephalexin     
4)  Vancomycin

Cephalosporins can cause allergic reactions in people with penicillin allergy. The overall rate of allergy to cephalosporins in people with penicillin allergy is approximately 5 to 10%, although rates may be higher for certain people. Allergic reactions to cephalosporins can be severe and even lifethreatening;
it is generally recommended that those allergic to penicillin avoid cephalosporins all together.

Protamine sulphate reverses the effect of

1)  Meperidine 
2)  Atropine
3)  Hepartn 
4)  Strychnine.

A personalized consent form helps tailor the information provided to the patient's specific treatment, ensuring they are aware of the risks, benefits, and alternatives before making a decision.

In mixed dentition, which of the following may be considered as a self correcting problem with age?

1) Unilateral loss of primary canine
2) Lack of interdental spaces
3) A distal step 
4) Open bite

SOLUTION

The possibility that a distal step would become class II is very real, and this not self correcting problem. When the central incisors erupt, these teeth use up essentially all of the excess space in the normal primary dentition. With the eruption of the lateral incisors, space becomes tight in both arches.

Normal child will go through a transitory stage of mandibular incisor crowding at age 8 to 9 even if there will eventually be enough room to accommodate all the permanent teeth in good alignment. In other words, a period when the mandibular incisors are slightly crowded is a normal developmental stage.

Continued development of the arches improves the spacing situation, and by the time the canine teeth erupt, space is once again adequate.

For patients with vision impairments, what is a useful strategy for effective dental communication?
1) Maintaining a silent environment
2) Verbal acknowledgment of actions
3) Rapid speech to complete the consultation quickly
4) Avoiding physical guidance

A patient undergoing caesarean section following prolonged labour under subarachnoid block developed carpopedal spasm. Lignocaine was' used as anaesthetic agent. The most likely' diagnosis is:

1) Amniotic fluid embolism

2) Lignocaine toxicity

3) Hypocalcemia

4) Hypokalemia

Hypocalcemia

Patient developing carpopedal spasm is indicative of hypocalcemia. Lignocaine in subarachnoid block can not cause hypocalcemia rather can cause hypercalcemia by releasing calcium from sarcoplasmic retinaculum (that is why amide local anaesthetics may trigger malignant hyperthermia).

What is the typical pH of a healthy oral environment?

1) 5.0-5.5.

2) 6.0-6.5.

3) 7.0.

4) 7.5-8.0.

A healthy oral environment has a neutral pH of around 7.0, which helps maintain the integrity of the tooth structure and prevent dental decay.

Which of the following is NOT a typical adverse effect of opioids?
1) Diarrhea
2) Somnolence
3) Constipation
4) Nausea

Opioids are commonly associated with constipation due to their effect on the gastrointestinal tract, which slows down bowel movements. They also frequently cause somnolence and nausea due to their action on the central nervous system. Diarrhea, however, is not a typical side effect of opioid use. In contrast, opioids are often used to treat diarrhea associated with conditions such as irritable bowel syndrome and other gastrointestinal disorders due to their constipating effects.
