Abstract
Objective: To reveal the sonographic characteristics of various foreign bodies and dental materials to aid diagnosis. Methods and materials: 24 objects consisting of various dental materials and foreign bodies were included in the study. Objects were embedded in bovine gelatin. Images of the objects were obtained by conventional radiography and ultrasonography (USG). Opacities were evaluated by conventional radiography. Their visibility and posterior acoustic behaviors were examined by USG. In addition, the actual sizes of the objects and their dimensions measured by USG were compared. Results: All objects included in the study, including non-opaque ones, could be visualized by USG. When the posterior acoustic behavior of objects was examined, 15 of the objects (62.5%) caused posterior acoustic shadowing on USG. While 6 of the objects (25%) did not have any USG artifacts, 2 of them (8,3%) had comet tail artifact and 1 of them (4,2%) had reverberation artifact. There was no statistically significant difference between the actual dimensions of the objects and their dimensions measured by USG (p > 0,05). Conclusion: USG is a very useful technique for imaging foreign bodies and dental materials, it can even show objects that cannot be seen in X-rays on in-vitro environment.
