Abstract

OBJECTIVE

To compare intraoral periapical radiography with 3D images for the diagnosis of periapical pathology.

STUDY DESIGN

Maxillary molars and premolars and mandibular molars with endodontic problems and examined with periapical radiographs and a 3D technique (3D Accuitomo) were retrospectively selected and evaluated by 3 oral radiologists. Numbers of roots and root canals, presence and location of periapical lesions, and their relation to neighboring structures were studied.

RESULTS

Among 46 teeth, both techniques demonstrated lesions in 32 teeth, and an additional 10 teeth were found in the Accuitomo images. As regards individual roots, 53 lesions were found in both techniques, and 33 more roots were found to have lesions in Accuitomo images. Artefacts were sometimes a problem in Accuitomo images. In 32 of the 46 cases, all observers agreed that additional clinically relevant information was obtained with Accuitomo images.

CONCLUSIONS

A high-resolution 3D technique can be of value for diagnosis of periapical problems.

摘要

目的

比较口腔内根尖片与三维影像在根尖周病变诊断中的应用。

研究设计

回顾性选取有牙髓病问题的上颌磨牙、前磨牙以及下颌磨牙，采用根尖片和三维技术（3D Accuitomo）进行检查，并由3名口腔放射科医生进行评估。研究牙根和根管数量、根尖周病变的存在及位置，以及它们与邻近结构的关系。

结果

在46颗牙齿中，两种技术均在32颗牙齿中发现病变，在Accuitomo影像中还额外发现10颗牙齿有病变。对于单个牙根，两种技术均发现53处病变，Accuitomo影像中还发现另外33处牙根有病变。伪影有时是Accuitomo影像中的一个问题。在46例中的32例中，所有观察者均认为Accuitomo影像提供了更多临床相关信息。
