Question 1: At what age do the primary (deciduous) mandibular central incisors typically erupt?
- 6–10 months (Correct answer)
- 12–16 months
- 16–20 months
- 20–24 months
Correct answer: 6–10 months
The mandibular primary central incisors are usually the first teeth to erupt, typically appearing between 6 and 10 months of age.
Question 2: Which behavior management technique involves explaining a procedure in simple terms, demonstrating on a model, and then performing it on the child?
- Tell-Show-Do (Correct answer)
- Desensitization
- Positive reinforcement
- Voice control
Correct answer: Tell-Show-Do
Tell-Show-Do is a foundational pediatric dental technique that reduces anxiety by familiarizing children with each step before it is performed.
Question 3: Which pulp treatment is indicated for a primary tooth with reversible pulpitis limited to the coronal pulp?
- Pulpotomy (Correct answer)
- Pulpectomy
- Direct pulp cap
- Extraction
Correct answer: Pulpotomy
A pulpotomy removes the affected coronal pulp while preserving healthy radicular pulp tissue in primary teeth with reversible coronal pulpitis.
Question 4: Stainless steel crowns are the preferred restoration for primary molars with which condition?
- Extensive caries involving multiple surfaces (Correct answer)
- Small pit-and-fissure caries only
- Smooth surface caries on proximal contacts
- Superficial enamel demineralization
Correct answer: Extensive caries involving multiple surfaces
Stainless steel crowns provide full-coverage protection and are the gold standard for primary molars with large or multi-surface carious lesions.
Question 5: Nursing bottle caries (early childhood caries) most commonly affects which teeth first?
- Maxillary primary incisors (Correct answer)
- Mandibular primary incisors
- Primary first molars
- Primary canines
Correct answer: Maxillary primary incisors
Prolonged bottle feeding pools sugary liquids around the maxillary anterior teeth, making the upper primary incisors the first and most severely affected.
Question 6: What is the recommended fluoride varnish application schedule for high-caries-risk children under 6 years of age according to ADA guidelines?
- Every 3–6 months (Correct answer)
- Once per year
- Monthly
- Only at initial diagnosis
Correct answer: Every 3–6 months
The ADA recommends fluoride varnish application every 3 to 6 months for children at elevated caries risk to maximize preventive benefit.
