摘要

目的是研究上颌犬科疑似异位疹患者的断层扫描特征,并评价转诊患者的标准是否合适。在1年的时间里,当口腔内x线检查不足以描述犬的位置和邻近牙齿的情况时,所有患者(n=63)进行了异位上颌尖牙的断层扫描检查,采用锥形束计算机断层扫描(CBCT)进行检查。在转诊患者中,有统计学意义的女孩比例过高(63.5%)。女孩的平均年龄为146.0 +/- 22.2个月,男孩的平均年龄为151.8 +/- 17.8个月,差异无统计学意义。总共检查了91个上颌犬齿位置,其中33个(36%)在相邻牙齿的根表面发现了吸收,绝大多数是侧门牙。由于偶尔会有一颗以上的牙齿受到影响,因此吸收的总数为38颗,其中14颗到达牙髓(37%)。考虑到牙齿的频率,邻近异位爆发的上颌犬齿,受到吸收的影响,可以得出结论,使用的转诊标准是适当的。考虑到患者年龄小,可以推荐使用CBCT技术进行断层扫描,这样可以检查小体积并产生高质量的图像。

Characteristics of patients referred for Cone Beam Computed Tomography (CBCT) of ectopically erupting maxillary canines.

The aim was to study the characteristics of patients referred for tomographic examinations of maxillary canines suspected of ectopic eruption and evaluate whether the criteria used for referring the patients could be considered appropriate. During a 1-year-period all patients (n=63) referred for tomographic examinations of ectopically erupting maxillary canines, when intra-oral x-ray examinations were insufficient to describe the position of the canine and the conditions at adjacent teeth, were examined by means of Cone Beam Computed Tomography (CBCT). There was a statistically significant overrepresentation of girls (63.5%) among the referred patients. The mean age for the girls was 146.0 +/- 22.2 months and for the boys 151.8 +/- 17.8 months, a statistically non-significant difference. In total, 91 maxillary canine sites were examined and in 33 of the examined sites (36%) a resorption was found in the root surface of an adjacent tooth, in the vast majority the lateral incisor. Since more than one tooth was occasionally affected the total number of resorptions was 38 of which 14 had reached the pulp (37%). Considering the frequency of teeth, adjacent to ectopically erupting maxillary canines, that were affected by resorptions it can be concluded that the referral criteria used were appropriate. Given theyoung age of the patients it can be recommended that tomography should be performed with CBCT techniques that permit the examination of small volumes and result in high quality images.
