Wooden Foreign Bodies in the Jaw
Foreign bodies are quite common in oral and maxillofacial region. Radiopaque objects like teeth, metals and gravels are easily detectable in the radiograph. But non radiopaque objects such as wood particles are difficult to locate. Sometimes advanced imaging modalities like Computed Tomography and Magnetic Resonance Imaging is required to correctly detect and locate the position of foreign bodies. In many instances, Computed tomography and Magnetic Resonance Imaging may not be available in the dental office and hospitals for the detection of foreign bodies. In such situations, it is important to use various available conventional radiographic techniques for the localization of foreign bodies. Exact localization of foreign body is important for planning the treatment required for its retrieval without much tissue damage. Plain film radiography is the initial screening modality used for the detection of suspected foreign body. But about one third of all the foreign bodies are missed in the initial radiographic examination. In case of a wooden foreign body only 15% are well visualized on plain radiographs and are therefore often missed or misdiagnosed. So, different radiographic technique should be used to localize the object instead of relying on a single radiographic image. Here we present a unique case of foreign body entrapped in the soft tissue appeared initially as osteomyelitis and fracture of mandible in the digital panoramic radiograph and finally detected as foreign body in mandibular occlusal radiography.
