Resorption Voorbeeldclausules

Resorption. Twenty-two transplanted teeth (39.3%) showed one or other form of root resorption (see: Introduction, Figure 3) and 34 teeth (60.7%) showed no resorption at all. Twenty transplanted teeth (90.9%) showed external root resorption while only two teeth (9.1%) showed internal root resorption. One specific radiological case of a transplanted canine, which showed external root resorption, more specifically replacement resorption, is presented in Figure 11. Figure 11A illustrates replacement resorption of the transplanted canine in the right upper jaw on a periapical x-ray. Cross sections of a cone-beam volumetric scan through the same transplanted canine are shown in Figure 11B and C, where the entrance of the alveolar bone in the tooth becomes clear. In Figure 12 a particular case is shown in which the diagnosis based on the periapical radiograph (Figure 12A) differs from the diagnosis based on the cone-beam scan (Figure 12B). On the periapical radiograph the apical root contours of the transplanted canine were not clear suggesting there is some apical resorption. The cone-beam scan, however, showed that there was no root resorption and that the tooth is placed outside the alveolar socket.
