Periodontology — in the LDEK question base
Periodontal disease and the 2017 classification, non-surgical and regenerative treatment, oral mucosal disease.
- Questions in base
- 194
- Share of base
- 7.8%
- Roughly on the paper
- ~11
The "on the paper" figure assumes the 140 questions drawn from the base are distributed in proportion to its composition. CEM does not publish per-field quotas, so treat it as an order of magnitude rather than a promise.
Required reading — periodontology
The list CEM publishes for this field. Questions are written from these titles, so where a lecture and a listed textbook disagree, the textbook decides.
Titles appear exactly as CEM lists them. Most are Polish editions with no English translation — a practical constraint of sitting this exam in English, not an oversight here.

How to get through this field
194 questions is a finite, countable set — at twenty a day you are through it in 10 days. The difficulty is not the volume. It is that the CEM listing gives you the questions and nothing else: no answer key, no explanation and no indication which of the books above the answer came from.
That matters more in dentistry than in medicine, because LDEK questions repeat between sessions less often. Memorising letters from the base will not carry you — understanding why the other four options are wrong is what transfers to the questions you have not seen.
