2D Versus 3D Radiographs in the Localization of Upper Impacted Canines

Seventeen patients diagnosed with the extraction-based treatment of impacted maxillary canines will be included in this study. Each patient will undergo conventional 2D radiography including panoramic, and lateral cephalometric, in addition to 3D imaging by cone beam computed tomography (CBCT) images.A set of variables will be evaluated on 2D and 3D images by a panel of assessors and then these results will be compared with the gold standard which will be established based on surgical detection and direct visualization of the impacted canine.

Inclusion Criteria:Patients from both gender (Male and female), Age range: 14-27 years.Unilateral impaction of the maxillary canines requiring surgical extraction.Non-syndromic patients without any pathology of the maxillofacial region (benign or malignant tumor, cleft lip or cleft palate, trauma)Patients with a set of panoramic and lateral cephalometric images, in addition to CBCT radiograph (CBCT is indicated for treatment planning)The time period between taking the radiological records and undergoing the surgical intervention does not exceed four weeksExclusion Criteria:Patients who had a systemic disorder, cleft lip/cleft palate, craniofacial syndrome, traumatic injury, and congenital number anomaly.Patients had previous orthodontic treatment.
