• To discuss the accuracy of localization and clinical usefulness of spiral CT for anterior maxillary impacted teeth. In 89 children with impacted teeth in our department during June 2004 and December 2009, Spiral CT was performed in 30 cases whose impacted teeth can't be localized clearly by conventional occlusal film and panoramic radiogragh. Multip-lanarreformation(MPR) and the surface shaded display(SSD) of the spiral CT were used to observe the number,size, shape,location,its relationship with adjacent tissue,angle between crown and root of the impacted teeth. The region of operation was exposed to evaluate the accuracy of localization and the value of clinical application of the Spiral CT. It was found that the number,size, shape,location,angle between crown and root of all the 33 impacted teeth could be displayed accurately. Spiral CT enables us to make a quick and accurate diagnosis of teeth impaction in the maxilla and can provide the best path for operation,which is helpful for pretreatment evaluation
