Radiographic examination of a 40 years old female displayed radiolucent regions adjacent to several mandibular teeth, all of which demonstrated pulp vitality during electric testing. What do these regions signify ?
Show answer Hide answer
Answer: B. Periapical osteofibroses
Explanation
Periapical osteofibroses present as radiolucent areas near tooth roots that maintain normal pulp vitality. These benign fibro-osseous lesions replace normal bone with fibrous tissue and cementum-like calcifications. Electric pulp testing confirms normal nerve and blood supply, ruling out necrotic pulpal pathosis. Periapical cemento-osseous dysplasia is a non-neoplastic bone condition frequently affecting mandibular anterior teeth. Early lesions appear completely radiolucent before developing mixed and radiopaque internal structures over time. Affected teeth require no endodontic therapy because pulpal necrosis is absent in these dysplasias.
Recognizing this benign condition prevents unnecessary and destructive root canal treatments on vital teeth. Radiographic follow-up confirms lesion stability without requiring surgical intervention or extraction. Middle-aged female patients show the highest demographic predilection for developing cemento-osseous dysplasias. Multiple granulomas originate from necrotic pulpal bacteria, resulting in negative electric pulp testing. Chronic periapical abscesses involve infected, non-vital pulpal tissues that fail electric vitality evaluations. Bone hypoplasias involve structural developmental deficiencies rather than reactive periapical fibro-osseous lesions.
