What distinguishes CONDENSING OSTEITIS from IDIOPATHIC OSTEOSCLEROSIS on X-ray?
Show answer and explanation
Correct answer: B. Condensing osteitis always = NONVITAL tooth + apical inflammation; idiopathic = VITAL tooth, unknown cause
✓ B) Key distinction: Condensing osteitis = NONVITAL tooth; Idiopathic osteosclerosis = VITAL tooth.
CONDENSING OSTEITIS: localized increased bone radiodensity at root apex due to low-grade chronic pulpal inflammation; associated tooth is ALWAYS NONVITAL; may have widened PDL space or periapical radiolucency; treatment = RCT or extraction. IDIOPATHIC OSTEOSCLEROSIS (bone scar, focal sclerosing osteomyelitis): area of increased bone density of UNKNOWN origin; associated tooth is VITAL; regular PDL space; no treatment needed. The PULP VITALITY TEST is the key diagnostic differentiator. Multiple idiopathic osteoscleroses → consider Gardner's syndrome.
