Use of Panoramic X-Ray to Determine Position of Impacted Maxillary Canines

Diagnostic Value of Panoramic Radiography in Determining the Position of Impacted Permanent Maxillary Canines

“…Several studies have found 65 degrees to be the cut-off point value for α angle (10,11), which is consistent with the results of the current study. It seems that this value is similar in different races, so 65 degrees can be used as the cutoff value in different populations.…”

“…The accuracy of this method was 59.4%. The agreement panoramic radiography using α angle is valid in localizing impacted maxillary canines, which is inconsistent with the results of the current study (10). In the two aforementioned studies, teeth with horizontal or vertical malocclusion or a restored mesiodistal cusp have not been excluded from the study.…”

“…Canines determine the occlusion, stability, form and function of dental arch (10). Impacted canines may lead to such problems as displacement and resorption of adjacent teeth, cystic degeneration, canine ankylosis, and a small dental arch (9).…”

“…Surgical exposure is performed from buccal or palatal sides. When the tooth is nearer to the buccal cortex, access is much easier from the buccal vestibule, and when it is nearer to the palatal cortex, access is easier from the palatal mucosa (10).…”

“…The position of canines can be determined by some radiologic methods (10). One method of tooth localization is panoramic radiography, which uses such variables such as angulation, magnification and superimposition (11).…”
