Abstract
Early diagnosis of unerupted supernumerary teeth is very important. Detailed examinations and evaluations of these teeth with Three Dimensional (3D) images are very beneficial in terms of treatment planning and avoiding complications, which may occur. 3D imaging in Dentistry offers many advantages with respect to diagnosis and treatment planning. The applications of software-3DCT images for detailed evaluation of impacted supernumerary teeth: location, number, morphology and positional area, to avoid their possibility complications by early choosing the proper surgical treatment. A descriptive study including 98 unerupted supernumerary teeth from 75 healthy patients between 10 and 43 years of age. Reasons for patients attendance included : malocclusion ,lack of eruption of permanent teeth ,prominence of gingival ,diastama, ,cystic lesion, caries and pain in different regions of dental arches, taking into account the variables of personal data, gender, age, location, morphology, number and positional area, related complications,3DCT scans study and correlated with surgical approaches and treatment.Incidence in impacted supernumerary teeth is higher among male patients (ratio M: F of 1.8:1) .They are most frequently located in the maxilla(64.28%) mainly in the premaxilla within the central incisors mesiodens (40.82 %) were detected by 3DCTscans ,most of them classified under Type III ( 72.5%). Most cases present only single unerupted supernumerary teeth (77.33%). The conical shape is the commonest morphology (34.69%).The diastema registered the greatest proportion (40.81%) of complications cases .Surgical removal of these teeth was done by labial or buccal approaches in (45.91%) of cases. 3DCT radiographies achieved to diagnosis and determine the exact situations, identified morphology, determined number presented and determined the position types of whole impacted supernumerary teeth that they were proved surgically to be in the same locations, similar shapes, right number and correct anatomical positions. With less invasive surgical interventions and less operation time. Early treatment planning of the impacted supernumerary teeth, the exact diagnosis of anatomical location, shape, number, position of mentioned teeth is an important issue to avoid their complication in the future.
