| Abstract: | Objective:The aim of the study was to investigate the clinical value of CBCT in the diagnosis and location of supernumerary teeth.Method:123 supernumerary teeth cases of patient with complete medical history data was selected to take CBCT.Level fault and optional fault was T:0.43 mm,S:0.5 mm;Panoramic fault was T: 15 mm,D:1.0 mm.The predilection sites,number and influence to the arch were observed in CBCT 3-D reconstruction,and the images were analyzed.Result:The number,size,location and the relation with the adjacent tissue of supernumerary teeth were clearly displayed in the CBCT images.Conclusion:CBCT can provide thorough image information on supernumerary teeth,and it was helpful to make and carry out the treatment plan. |
