Answer: Most in mandibular anterior region. Over 50% occur in pairs.
Q: What is the risk of topical anesthetics in infants?
Answer: Methemoglobinemia
Q: What is the possible etiology of natal teeth?

Hallerman- Streiff syndrome
Q: List 4 risk factors that increase caries risk.
Answer: 1. Primary caregiver has active caries 2. Low SES or recent immigrant 3. Over 3 snacks
of high carbs or drinks 4. SHCN

Q: Should a class II resin be light cured again after polishing?
Answer: Yes
Q: What are the properties of RMGI restorations?
Answer: 1. Chemically bond to enamel and dentin 2. Release fluoride 3. Good esthetics 4. Less
moisture-sensitive than resin
Q: What are the indications for a Class V RMGI?
Answer: 1. Difficulty with isolation 2. Poor behavior 3. Moderate caries risk (due to FL release)
Q: What are the indications for Interim therapeutic retorations?
Answer: 1. Uncooperative patients 2. Patients with special needs 3. Interim for caries control
