Which of the following obturation techniques is suitable for cases with internal resorption?
Take your time. Choose an answer to see the key and the written explanation, exactly as the app shows them.
Correct answer: d · Thermoplasticized injectable gutta-percha technique
Internal resorption defects are irregular, so a thermoplasticized injectable gutta-percha technique best fills the irregular resorptive space.
That's 1 of 1,041 past-paper questions, explained like the rest.

Practical skills are learned with your hands, not on a phone. There is no practical-exam material in Enamel, and we would rather tell you now.
Each explained in writing, unless noted.
Figures counted from the question bank, not estimated. Each paper is counted in full, so a question that appeared on two papers counts twice: the 1,100 are 1,008 different questions. Disagree with a key? Flag it while you practise, and write to us at enamel.colloquium
02 · Exam conditions
The written mock draws 120 questions at random from the 1,100 in the bank, spread across subjects, and runs the Phase 1 clock. It ends itself when time runs out and, unless you switch on instant answers, shows nothing until you finish. Every mock is a new draw.
At exam speed, you reach question 60 by minute 50.

A past-paper PDF gives you the questions and, for the dated papers, the ministry's list of answers, but never why. In Enamel every one of the 1,100 has its answer key, and the 1,041 from official past papers are explained in writing. You also get a timed mock, a review of your mistakes and the oral summary, searchable on your phone.
The one that lasts until your oral. Under the passes, “Not sure? Count back from your oral” picks the pass for your date.
One month free on 3‑ and 6‑month passes bought by 31 December 2026 (23:59 Beirut time), added when the payment is confirmed: 3 months become 4, 6 become 7. It applies when you add time to a pass, too. A purchase gets at most one free month. A pass ordered by then still counts if its payment is confirmed by the end of 3 January 2027. A refund of that pass also removes the free month.
Yes, from most countries. Pay by Visa or Mastercard, or with PayPal, Apple Pay or Google Pay. Payments can't be taken from Russia, Belarus, Syria, Iran or Iraq, from the Crimea, Donetsk, Kherson, Luhansk and Zaporizhzhia regions of Ukraine, or from other places under international sanctions. A card issued in Russia won't go through either, even from Lebanon. Your pass starts the day you pay, so you can buy it once you're back in Lebanon. Until then, try the 20 free questions. Questions? Write to enamel.colloquium
No. Every pass is one payment and nothing renews. If you need more time, buy again before your pass ends and the new time is added on. If your pass has already ended, buy again and you carry on where you stopped: your progress stays on your account.
