| Popis: | A small computed tomograph (CT) for dental use (Ortho Cubic Super High Resolution-CT: Ortho-CT) was developed by the Department of Radiology, Nihon University School of Dentistry. It is characterized by the small size of the unit as well as by the ability to produce high-resolution images with a low radiation dose.Ortho-CT is a dental multifunctional tomographic unit equipped with a small imaging intensifier (I.I.). The exposure time is shorter and the radiation exposure is lower for Ortho-CT than for conventional CT. In this study, we used Ortho-CT for the diagnosis and treatment planning of lesions arising in the maxillary region.High resolution images of Ortho-CT could easily identify the extent of lesions and evaluate the positional relationship with the maxillary sinus and adjacent teeth. In addition, morphometry could be performed accurately.Ortho-CT could reproduce three-dimensional images from any tomographic image by only one exposure. Because it provides high-resolution images, accurate diagnosis can be done. Because there were minimal differences among individual observers in interpretation of the images, this technique was useful in planning efficent treatment and shortening the treatment time. |
