摘要

摘要简介:由于大多数口腔疾病只能通过x射线放射成像来诊断,因此x射线放射成像是常用的方法。由于在x射线之前,期间或之后可能发生的错误,正确识别放射图像上的元素也可能很困难。这些错误被称为工件。研究目的:我们研究的目的是通过进行对照x光检查,将二维和三维牙科x光检查(口腔内或口腔外)上可能出现的伪影与研究区域的实际病理区分开来。材料和方法:在我们的研究中,我们观察、评估和比较了80张肺泡后x光片、45张正骨断层摄影(OPG)和35张锥形束计算机断层摄影(CBCT)。如果出现伪影或错误,则在5天内重复x光或进行CBCT。对于OPGs,另一种选择是进行肺泡后x光检查以确定最终诊断。结果:80例肺泡后x线片中,13例(16.25%)发现假影。其中,只有4例(5%)在临床检查或CBCT后改变了诊断和治疗计划。在总共45例opg中,17例(37.7%)出现假影,但只有17.7%(8例)的百分比影响了诊断。在35例cbct中,其中10例(28.57%)存在金属构件或植入物的假体作品,发现了特定的假物,但它们的存在并不影响诊断。结论:医生有必要了解口腔区域的解剖结构、各组成部分最炽热的外观以及可能出现的不同类型的伪影。对照x射线是一种非常常用的可能性,但在某些情况下,需要尽量减少辐射暴露。

Contributions to the study of common artifacts and errors in conventional and three-dimensional radio-imaging used in the evaluation of odontal, endodontic and periodontal pathology.
Abstract Introduction: X-ray radio imaging is commonly used because most diseases in the oral area can only be diagnosed by using this method. Proper identification of elements on a radiological image may also be difficult due to errors that may occur before, during or after the X-ray. These errors are called artifacts. Aim of the study: The aim of our study is to distinguish the artifacts that can occur on two-dimensional and three-dimensional dental X-rays (intraoral or extraoral) from the actual pathology of the investigated area, by performing control X-rays. Material and Methods: In our study we viewed, assessed and compared a number of 80 retroalveolar X-rays, 45 orthopantomographs (OPG) and 35 Cone Beam Computer Tomography (CBCT). In case of artifacts or errors, X-rays were repeated within 5 days or a CBCT was performed. In the case of OPGs, another option was to perform retroalveolar X-rays to establish the final diagnosis. Results: From a total of 80 retroalveolar X-rays, in 13 cases (16.25%) we found artifacts. Of these, in only 4 cases (5%) diagnosis and treatment plan were changed following a clinical examination or a CBCT. In the case of OPGs, out of a total of 45 OPGs, 17 (37.7%) presented artifacts, but only in a percentage of 17.7% (8 cases) they affected the diagnosis. Of the 35 CBCTs, in 10 of them (28.57%) prosthetic works with a metal component or implants were present, with specific artifacts found, but their presence did not influence the diagnosis. Conclusion: It is necessary for doctors to know the anatomy of the oral region, the most fervent appearance of the components and the different types of artifacts that may occur. Control X-ray is a very commonly used possibility, but there are cases where radiation exposure needs to be minimized.
