Widened pdl space: malignancy or fractured tooth? shahbazi

Despite the development of several modern imaging modalities, radiography remains the first and the most important mode of investigation for evaluating jaw lesions. Osteosarcoma is the most common primary malignant bone tumor, accounting for approximately 20% of the sarcomas, but only 5% of the osteosarcomas occur in the jaws. Malignant lesions are known to quickly grow downward into the periodontal ligament (PDL) space, resulting in an irregular widening and destruction of the lamina dura. Often, root fractures can result in a similar radiographic appearance of the surrounding periodontium.
