Question 43 (part 2) · LDEK · Gingival recession and mucogingival surgery
Recession classification according to Cairo distinguishes several types of recession, in which RT1 means:
- A. recession without CAL loss in interdental spaces, CEJ is interproximal undetectable.
- B. recession with CAL loss in interdental space ≤ than Cal from buccal side.
- C. recession with CAL loss in interdental space > than Cal from buccal side.
- D. recession with simultaneous CAL loss both in vestibular and lingual/palatal direction without CAL loss in interdental space.
- E. all of the above-mentioned answers are false.
Hint
Cairo's three types depend on whether interproximal attachment has been lost and how that loss compares with the buccal loss.
