概括
儿科牙医认为霍尔技术 (HT) 预制金属冠 (PMC) 与放射图上的常规PMC相似. 然而,他们可以识别HT-PMC的频率是传统PMC的五倍,这表明HT-PMC的支持率很高.
科学领域:
- 儿科牙科 儿科牙科
- 放射学 放射学是一门学科.
- 牙科材料 牙科材料
背景情况:
- 霍尔技术 (HT) 预制金属冠 (PMC) 是儿童牙科中广泛使用的修复选择.
- 人们担心HT-PMC与传统的 (C) PMC之间存在潜在的尺寸差异.
- 了解牙医的感知和诊断能力对于临床实践至关重要.
研究的目的:
- 评估小儿牙医对HT-PMC的看法.
- 评估PDs在咬翼放射图上区分HT-PMC和C-PMC的能力.
- 调查PD对HT-PMC的支持随着时间的推移的趋势.
主要方法:
- 一个在线横截面问卷在全球范围内分发给PDs.
- 调查问卷包括十张咬翼放射,每张HT-PMC和C-PMC的五张.
- 统计分析包括t测试,皮尔森基平方,费舍尔基平方和奇比 (OR),显著程度为p < 0.05.
主要成果:
- 在476个响应的PD中,大多数 (97%) 使用PMC,其中79%使用HT-PMC.
- 随着时间的推移,人们对HT-PMCs的看法发生了显著的转变 (OR 11.154).
- PDs可以比C-PMCs准确识别HT-PMC大约4.63倍 (HT-PMC的OR是24.857,C-PMC的OR是5.361).
结论:
- 儿科牙医表现出高水平的认识和使用HT-PMCs.
- 虽然HT-PMCs和C-PMCs之间存在感知到的放射相似性,但HT-PMCs的识别能力明显更强.
- 这些发现表明HT-PMC在临床实践中越来越受欢迎和得到更好的认可.

01:20Imaging Studies for Cardiovascular System III: X-Ray
219
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...
