Sample MCQ 1: Class II malocclusion management

A 12-year-old has increased overjet (8 mm), deep overbite, and a retrognathic mandible. She is in the pubertal growth spurt (CS3) and has a full-cusp Class II molar relationship bilaterally.

A. Twin Block functional appliance
B. Rapid maxillary expansion (RME) only
C. Extraction of four first premolars and full fixed appliances now
D. Orthognathic surgery after growth completion only

Correct answer: A

Explanation: A growing Class II due to mandibular retrusion is best managed with a functional appliance timed to peak growth (e.g., Twin Block) to improve sagittal jaw relationship and reduce overjet before or alongside fixed appliances. RME alone targets transverse deficiency; extractions are case-dependent (often camouflage) and surgery is reserved for severe discrepancies after growth.

Sample MCQ 2: Posterior crossbite treatment choice

An 8-year-old presents with a unilateral posterior crossbite and a functional shift on closure. There is a narrow maxillary arch and mild crowding. No TMJ symptoms are reported.

A. Rapid maxillary expansion (RME)
B. Cervical headgear
C. Observation until permanent dentition
D. Lower lingual holding arch

Correct answer: A

Explanation: A unilateral posterior crossbite with functional shift commonly reflects maxillary transverse deficiency. Early correction is recommended to eliminate the shift, improve arch width, and reduce asymmetric growth risk. RME (or appropriate expansion in mixed dentition) addresses the transverse problem; headgear is for sagittal correction, and observation can allow the asymmetry to persist.

Clinical reasoning, not trivia

Sample MCQ 3: Anchorage and biomechanics - space closure

A 16-year-old is treated with extraction of maxillary first premolars for Class II camouflage. You need maximum anchorage to retract maxillary canines and incisors with minimal mesial movement of maxillary molars.

A. Use Class II elastics without additional anchorage
B. Use a Nance button or transpalatal arch (TPA) only
C. Use temporary anchorage devices (TADs) to reinforce anchorage
D. Procline maxillary incisors to gain space

Correct answer: C

Explanation: When maximum anchorage is required, skeletal anchorage (TADs) provides the most reliable control of molar position during space closure. Class II elastics typically increase anchorage loss (mesial molar movement) and can procline lower incisors. Nance/TPA can help but may be insufficient for true maximum anchorage in many cases.
