Question 1: Early Childhood Caries
A 3-year-old presents with multiple smooth surface carious lesions and enamel breakdown on
maxillary incisors. The child’s dietary history reveals frequent night-time bottle use with juice.
What is the MOST appropriate initial management strategy?
A. Fluoride varnish only
B. Counseling on diet and oral hygiene
C. Comprehensive restorative treatment under local anesthesia
D. Extraction of all affected teeth
Answer: B and C
Rationale:
Early childhood caries management requires behavior modification (diet and oral
hygiene) and restorative treatment for functional and aesthetic reasons.
Fluoride varnish alone is insufficient in moderate-to-severe decay.
Extraction is reserved for non-restorable teeth.
Question 2: Pulp Therapy
A 6-year-old patient has a primary molar with deep caries, no spontaneous pain, but the
radiograph shows no periapical pathology.
Which pulp therapy is MOST indicated?
A. Pulpectomy
B. Pulpotomy
C. Extraction
D. Observation
Answer: B
Rationale:
Pulpotomy is indicated for primary teeth with reversible pulpitis and healthy radicular
pulp.
Pulpectomy is indicated if radicular pulp is infected.
, Extraction is only if the tooth is non-restorable.
Question 3: Space Maintenance
A 7-year-old loses a primary first molar prematurely due to caries.
What is the most appropriate management?
A. No intervention
B. Space maintainer
C. Immediate extraction of adjacent teeth
D. Orthodontic appliance
Answer: B
Rationale:
Premature loss of primary molars can cause mesial drift of permanent teeth, leading to
malocclusion.
Space maintainers preserve arch integrity until permanent tooth eruption.
Question 4: Behavior Management
A 5-year-old refuses to cooperate during dental treatment and shows high anxiety.
Which technique is considered FIRST-line behavior management?
A. General anesthesia
B. Tell-show-do
C. Protective stabilization
D. Sedation
Answer: B
Rationale:
Tell-show-do is a non-pharmacologic, first-line approach for managing anxious
pediatric patients.
Sedation or GA is reserved for extreme cases when behavioral guidance fails.
Question 5: Traumatic Dental Injury
,A 9-year-old presents with a luxated permanent central incisor after a fall. The tooth is tender,
mobile, but not displaced out of the socket.
What is the appropriate initial management?
A. Immediate extraction
B. Repositioning and flexible splint for 2 weeks
C. Observation only
D. Root canal therapy immediately
Answer: B
Rationale:
Subluxation or minor luxation requires repositioning if needed, flexible splinting,
and follow-up.
Root canal therapy is indicated later if pulpal necrosis develops.
Question 6: Dental Radiography
A 4-year-old presents with multiple interproximal carious lesions suspected on radiographs.
Which type of radiograph is MOST appropriate?
A. Panoramic only
B. Bitewings
C. Periapical of all teeth
D. Occlusal only
Answer: B
Rationale:
Bitewing radiographs are preferred for detecting interproximal caries in children.
Panoramic is not detailed enough for caries detection.
Question 7: Fluoride Use
A 2-year-old patient lives in an area with 0.3 ppm fluoride in water. Which fluoride therapy is
MOST appropriate?
A. Daily 1,000 ppm fluoride toothpaste
B. Fluoride varnish every 3–6 months
C. No fluoride needed
D. Prescription-strength fluoride rinse
, Answer: B
Rationale:
Topical fluoride varnish every 3–6 months is recommended for high-risk children <3
years, especially in areas with low fluoride.
Toothpaste is used in pea-sized amounts >2 years, rinse is not recommended for
toddlers.
Question 8: Malocclusion Screening
During a 7-year-old’s dental exam, you notice posterior crossbite with functional shift. What is
the preferred initial intervention?
A. Observation
B. Early orthodontic intervention (palatal expansion)
C. Extraction of primary teeth
D. Full orthodontic braces immediately
Answer: B
Rationale:
Posterior crossbite with functional shift should be corrected early with palatal
expansion to prevent skeletal asymmetry.
Observation may worsen the problem; braces are used later.
Question 9: Preventive Counseling
Parents ask about pacifier use beyond age 3. Which is the BEST advice?
A. Discontinue by age 3 to prevent malocclusion
B. Pacifiers are harmless regardless of age
C. Recommend thumb sucking instead
D. Only discontinue if speech problems appear
Answer: A
Rationale:
Extended non-nutritive sucking habits can lead to open bite and crossbite.
Discontinuing by age 3 prevents dental malalignment.
