The key feature distinguishing idiopathic osteosclerosis from condensing osteitis is:

  1. The size of the radiopacity
  2. The vitality/inflammatory status of the associated tooth's pulp
  3. The patient's age
  4. The arch in which it occurs
Show answer and explanation

Correct answer: B. The vitality/inflammatory status of the associated tooth's pulp

  • A. Size does not reliably separate the two.
  • B. Correct. Condensing osteitis is a reaction to pulpal inflammation (non-vital/inflamed pulp), whereas idiopathic osteosclerosis occurs around a normal, vital tooth.
  • C. Age is not the distinguishing factor.
  • D. Both occur in posterior areas; location is not definitive.
