Which space maintainer is indicated after premature loss of a mandibular primary first molar when the second primary molar is still present?
Answer: Band-and-loop appliance
A band-and-loop space maintainer is the appliance of choice when a single primary molar is lost but the adjacent posterior tooth is still present to serve as an anchor.
Which agent is the most commonly used for pulpotomy in primary teeth in the United States?
Answer: Mineral trioxide aggregate (MTA) or formocresol
Formocresol has historically been the standard, while MTA is increasingly preferred due to its biocompatibility and superior outcomes in primary tooth pulpotomies.
A child presents with multiple small, shallow ulcers on the labial and buccal mucosa with a prodrome of fever and malaise. What is the most likely diagnosis?
Answer: Primary herpetic gingivostomatitis
Primary herpetic gingivostomatitis caused by HSV-1 presents with fever, malaise, and widespread oral ulcerations on both attached and free mucosa in young children.
At what age should a child's first dental visit be scheduled according to the American Academy of Pediatric Dentistry (AAPD)?
Answer: By age 1 or within 6 months of first tooth eruption
The AAPD recommends establishing a dental home by age 1 or within 6 months of the eruption of the first primary tooth to enable early risk assessment and prevention.
Which eruption sequence is considered normal for the permanent dentition in the mandible?
Answer: First molar, central incisor, lateral incisor, canine, first premolar, second premolar, second molar
In the mandible, the first permanent molar and central incisor typically erupt around age 6, followed by lateral incisors, canines, and premolars.
Which type of ankylosis in primary molars is best managed by monitoring if the permanent successor is present and eruption is progressing?
Answer: Mild infraocclusion with permanent successor present
When infraocclusion is mild and the permanent successor is erupting normally, periodic monitoring is appropriate as the primary tooth will eventually exfoliate.
