Avoiding the Impacted Supernumerary Teeth Complications by Its Early Evaluation, Using Dental Three Dimensional Computed Tomography

Abstract

Early diagnosis of unerupted supernumerary teeth is veryimportant. Detailed examinations and evaluations of these teethwith Three-Dimensional (3D) images are very beneficial in termsof treatment planning and avoiding complications, which mayoccur. 3D imaging in Dentistry offers many advantages withrespect to diagnosis and treatment planning. The applications ofsoftware-3DCT images for detailed evaluation of impactedsupernumerary teeth: location, number, morphology and positionalarea, to avoid their possibility complications by early choosing theproper surgical treatment. A descriptive study including 98unerupted supernumerary teeth from 75 healthy patients between10 and 43 years of age. Reasons for patients attendance included :malocclusion ,lack of eruption of permanent teeth ,prominence ofgingival ,diastama, ,cystic lesion, caries and pain in differentregions of dental arches, taking into account the variables ofpersonal data, gender, age, location, morphology, number andpositional area, related complications,3DCT scans study andcorrelated with surgical approaches and treatment. Incidence inimpacted supernumerary teeth is higher among male patients (ratioM: 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 themclassified under Type III ( 72.5%). Most cases present only singleunerupted supernumerary teeth (77.33%). The conical shape isthe commonest morphology (34.69%).The diastema registered thegreatest proportion (40.81%) of complications cases .Surgicalremoval of these teeth was done by labial or buccal approaches in(45.91%) of cases. 3DCT radiographies achieved to diagnosisand determine the exact situations, identified morphology,determined number presented and determined the position types ofwhole impacted supernumerary teeth that they were provedsurgically to be in the same locations, similar shapes, right numberand correct anatomical positions. With less invasive surgicalinterventions and less operation time. Early treatment planning ofthe impacted supernumerary teeth, the exact diagnosis ofanatomical location, shape, number, position of mentioned teeth isan important issue to avoid their complication in the future.
