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. |
