概括

这项研究引入了一种新的3D方法,使用微型CT来可视化和量化牙中与年龄相关的生理牙硬化. 较老的牙显示了硬化牙的增加,证实了这种方法.

科学领域:

牙科解剖学牙科解剖学
放射学放射学是一门学科.
生物材料科学生物材料科学

背景情况:

生理牙硬化是一种与牙根的年龄相关的变化,以前仅在二维中可视化.
了解这种现象对于牙科诊断和治疗计划至关重要.

研究的目的:

提出和验证一种新的3D方法来可视化和量化生理性硬化牙.
为此目的,利用基于密度的微型计算机断层扫描 (micro-CT) 的灰色值.

主要方法:

来自已知时间年龄的马来男性人口的40个单根前被使用微型CT扫描.
重建了三维数据集,并使用FIJI (ImageJ) 软件对根牙进行了体积分析.

主要成果:

微型CT成功使得可视化,隔离和定量化高密度区域相应的硬化牙.
在灰色值配置文件中观察到一种特有的蝶形状图案.
来自31-60岁的个体的前显示,与年轻的牙相比,硬化牙区域更大.

结论:

这项试点研究证明了使用微型CT进行3D可视化和测量生理性硬化牙的可行性.
该方法的准确性取决于微型CT扫描仪的功能和图像处理软件.
建议使用先进的微型CT技术进行进一步的研究,以提高图像质量.

关键词:

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
