Angular (Vertical) Bone Loss

Bone loss angular to adjacent CEJs

Radiographic Appearance ofPeriodontal Disease

Periodontitis

Fuzziness and break in continuity of lamina dura, wedge shapedradiolucent areas, height of interdental septum is reduced

Normal Early

Severe-

Advanced

Crestal Continuity

Lack of definitive cortical

crest of bone (lamina dura)

may be indicative of disease

activity

Definitive radiopaque

cortical crest (lamina

dura)indicative of

stability/health

Interdental Craters

Intrabony Pockets

Furcation Involvement (F2 or F3)

Pocket depth (and/or recession) + radiolucency = furcation involvement II or III
