Cone-beam CT undersøgelse af retinerede hjørnetænder i overkæben

Abstract

Impaction of the maxillary canine has a population-based prevalence of 0.27-2.4%. Timely diagnosis and intervention are important factors in order to achieve a good long-term prognosis. Optimal treatment planning is based on relevant information from clinical and radiological examination methods. 3D radiological examination based on cone-beam CT provides a superior information about the canine anatomy, canine position, and the presence of pathological changes in the adjacent teeth (e.g. root resorption), when compared to 2D radiological examinations. However, despite these beneficial properties, research has suggested that routine CBCT radiology, in addition to a 2D radiological examination, seldom leads to a significant change in the treatment planning of impacted maxillary canines. The decision whether to use supplement CBCT examination should account for the financial costs and extra radiation dose to the patient, which is particularly critical for children and adolescents in growth.
