The diagnosis and antidiastole on supernumerary cusp of tooth by CBCT: a case report
Objective To report a case of supernumerary cusp on the bucca of left maxillary second molar diagnosed by Cone Beam Computed Tomography(CBCT), and to analyze its genesis,diagnosis and antidiastole. The clinic application of CBCT is correspondingly discussed. Methods The supernumerary cusp was diagnosed by oral general examination, oral local X-rayand CBCT. The respective features of supernumerary cusp, fused teeth, geminated teeth and concresence of teeth, especially differential points between them were discussed. Results A case of supernumerary cusp on the bucca of the left maxillary second molar was diagnosed definitely by the combined application of oral general examination, periapical radiograph and CBCT. Conclusion Oral accessory examinations are important, sometimes even necessary in diagnosing oral-maxillofacial diseases such as supernumerary cusp. CBCT has many advantages, such as short scanning time, low ionizing radiation, and high resolution. Therefore, CBCT can improve accuracy of diagnosis, which is why it has been applied in various areas of dentistry.
