Schemes and representative MDCT images of classification into 3 groups based on the presence or absence of continuity between the GT and the top of masses in alveolar bone.
<p><b>(A)</b> Scheme of Group 1, which was defined as cases in which an almost intact GT (asterisk) continues to the top of the mass (star). <b>(B)</b> An MDCT image of a mass classified as Group 1. (<b>C)</b> Scheme of Group 2, which was defined as cases in which an expanded GT (arrow) continues to the top of the mass (star). (<b>D)</b> An MDCT image of a mass classified as Group 2. (<b>E)</b> Scheme of Group 3, which was defined as cases in which the GT is not continuous with the tumor or cyst (star). <b>(F)</b> An MDCT image of a mass classified as Group 3.</p

Relationship between mass size and area of the major axis of continuity on MDCT imaging in AM, DC and OKC cases classified as Group 1 or 2.
<p>In AM (blue diamonds), a strong significant correlation was found between the mass size and the size of the continuity area (r = 0.741, p = 0.0001). In DC (green triangles), a very weak significant correlation was found between the mass size and the size of the continuity area (r = 0.167, p = 0.0028). In OKC (red Xs), there was no correlation between the mass size and the size of the continuity area (r = -0.089, p = 0.557).</p
