Which imaging feature corresponds to periodontal ligament space widening and bone loss seen in chronic periodontitis?

Which imaging feature corresponds to periodontal ligament space widening and bone loss seen in chronic periodontitis?

• A. Alveolar bone loss with PDL widening
• B. Increased radiopaque lamina dura
• C. Shortened tooth roots with dense pulp
• D. Uniform tooth density

Answer: (A)

Chronic periodontitis damages the structures that support a tooth, so radiographs typically show loss of alveolar bone around the roots along with widening of the periodontal ligament space where the ligament and surrounding tissues are inflamed. Seeing both alveolar bone loss and a broadened PDL space together directly reflects the destructive process affecting the bone and ligament, which is characteristic of this condition. The other options describe findings not typical of chronic periodontitis: increased radiopaque lamina dura suggests the opposite of bone loss; shortened roots with a dense pulp point to endodontic or developmental changes; and uniform tooth density indicates no bone loss or ligament alteration.
