Three-dimensional evaluations of supernumerary teeth using cone-beam computed tomography for 487 cases

Application of Cone-Beam Computed Tomography (CBCT) in diagnosis and evaluation of Supernumerary Teeth

“…Grimanis G.A, Kyriakides A.T., Spyropoulus N.D. [17] found that supernumerary teeth occur more frequently in the maxilla (90%) than in the mandible (10%). In this study, the locations of diagnosed supernumerary teeth were found in a larger proportion in the maxilla (95%) than in the mandible (5%), in agreement with other studies [1,17,18].…”

“…The acquired set of axial images is reconstructed into bi-dimensional sections (transaxial views and panoramic views) or 3-D representations. The 3-D images are generated and optimized after selecting the region of interest and adjusting the angle and grey level [18]. CBCT produces 3-D information on the facial skeleton and teeth, and also it is increasingly being used in many of the dental specialities, including orthodontics, orthognathic surgery, trauma and implantology [28,29].…”

Prevalence of Supernumerary Teeth in North Indian Population: A Radiological Study

“…Due to their shape and volume they often hinder eruption and development of the permanent tooth related to them, causing crowding, displacement, diastema, retention, radicular resorption [28]. If the supernumerary teeth are related to local disorders (diastema, delayed eruption or displacement) or if there is associated pathology, they should be extracted whenever the problem would be detected [29].…”

“…Thus, 3-dimensional evaluation of the dentition will be beneficial, not only to detect the precise location of supernumerary teeth and the contiguity to roots of erupted permanent teeth, unerupted teeth buds, and anatomical structures but also to distinguish between supernumerary and permanent teeth. 31 Providing space for the unerupted teeth may maximize the potential for eruption and also the root formation. 32 Space in the vertical, sagittal, and transversal dimensions can be obtained by extraction of the supernumerary and primary teeth, as well as anteroposterior and transversal expansion of the alveolar arch.…”

“…32 Space in the vertical, sagittal, and transversal dimensions can be obtained by extraction of the supernumerary and primary teeth, as well as anteroposterior and transversal expansion of the alveolar arch. 23,31,33 Farrar and Van Sickels 34 argued that the mechanical interference of supernumerary teeth is the reason for lack of eruption of permanent teeth. On the other hand, Hitchin and Fairley 35 suggested that the failure of resorption of alveolar bone is the reason for unerupted permanent teeth.…”
