Abstract
PURPOSE: The purpose of this study is to compare the ability and reliability of evaluating, completely impacted maxillary canine with conventional digital panoramic radiograph and 3D reconstructed CT data. MATERIALS AND METHODS: This prospective study was done with a total of 5 patients aged 12 to 28 years of age and patients were informed about the need for CT radiological assessment and consent was obtained. They were pre operatively assessed using, Conventional Digital Panoramic Radiographs with Stivaros and Mandall (2000) assessment criteria and 3 Dimensional Reconstructed Object from the Computed Tomographic data. RESULTS: Digital panoramic radiographs are 2 Dimensional image of a 3 Dimensional object with less accuracy and more distortion. 3-Dimensional object reconstructed CT data can be used to visualize the impacted maxillary canine in transparency and opaque views, 3-Dimensional object visualization with rotation in all axis, transparency and separate view of different structures, virtual tooth sectioning and sectional view of the crown or root alone, measuring the distance from impacted maxillary canine to the occlusal plane and adjacent structures, presence of cortication by accessing the bone density of the region, simulation of movement of tooth on the path of elevation, assessment of surgical approach to the impacted tooth. CONCLUSION: 3-Dimensional object visualization from CT data does not need any expertise to interpret and any one can visualize the exact anatomy and position of the impacted maxillary canine when comparing and evaluating with the digital panoramic radiographs.
