An 11-year-old patient presents to the emergency department at night after falling and hitting their mouth on a table edge. The parent reports the upper front tooth appears longer and is wobbly. What is the most important factor to determine during history-taking in this case?

• Lateral luxation

• Avulsion

What is the most appropriate immediate management for dental extrusion?

• Leave the tooth in its current position and refer to a dental clinic the next morning

• Reposition the tooth gently into its socket and stabilize with a flexible splint for 2 weeks

• Extract the tooth to prevent further complications and plan for future prosthetic replacement

• Perform root canal therapy immediately to prevent pulp necrosis

Following the immediate management that you have given, what is the recommended follow-up schedule you think appropriate for this patient?

• 2 weeks, 1 month, and discharge if asymptomatic

• Weekly for 1 month, then every 3 months for 2 years

• 2 weeks, 4 weeks, 6-8 weeks, 6 months, 1 year, and then yearly for 5 years

Which of the following is an advantage of a composite veneer compared to a ceramic veneer for a young adult?

In a patient who wants to improve aesthetics in short period of time, which factor should you emphasize most during treatment planning?

• Short-term cost only

• Longevity and conservative approach

When is the best time to perform shade selection for an anterior tooth restoration?
