概括

皮质腔体积 (PCV) 和牙尺寸因面部类型和咬而有所不同. 短脸的个体具有较小的PCV,而特定的结接触减少了结PCV,影响了牙科治疗计划.

科学领域:

牙科牙科是指牙科的专业.
矯正牙科矯正牙科是一種矯正牙科.
放射学放射学是一门学科.

背景情况:

脉腔体积 (PCV) 和牙尺寸对于内接入和放射性解释至关重要.
骨和牙缺陷可能会影响这些解剖特征.

研究的目的:

评估和比较PCV和大和下第一个牙和大中央切口的尺寸.
通过使用圆束计算断层扫描 (CBCT) 评估不同垂直和前后部缺陷对这些牙科参数的影响.

主要方法:

对184名约旦成年人的CBCT扫描进行了回顾性横截面分析.
受试者按垂直面部图案 (短,平均,长面) 和牙间位 (头到头,头到头) 分类.
使用ITK-SNAP软件测量PCV和尺寸;通过非参数测试和回归分析数据.

主要成果:

与平均和长脸组相比,在短脸个体中,牙的PCV明显较小.
在所有垂直组中,切割器PCV有所不同,在短脸组中,质厚度和冠状高度降低.
尖端到尖端的骨间消化与较小的骨PCV和缩小的尺寸相关;年龄和性别是显著的预测因素.

结论:

垂直骨模式显著影响PCV,短脸的个体表现出最小的体积.
骨间位,特别是骨间位,与减少的骨PCV有关.
在内脏牙接入规划和放射学解释中考虑骨和闭口变异,以避免误判脉大小.

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...
