概括

临床斑块指数,如图雷斯基修改的奎格利-海恩斑块指数 (T-QHPI) 和鲁斯托吉修改的海军斑块指数 (RMNPI),部分反映了实际的斑块量. 新的转换方程提高了口腔卫生研究结果的解释性.

科学领域:

口腔卫生研究的研究.
牙科诊断牙科诊断牙科诊断
牙周病学牙周病学

背景情况:

临床斑块指数是评估斑块控制有效性的标准.
在研究中观察到的效果大小因使用的特定指数而异.
本研究将三个斑块指数与实际斑块量化进行比较.

研究的目的:

评估图雷斯基修改的奎格利-海恩斑块指数 (T-QHPI),鲁斯托吉修改的海军斑块指数 (RMNPI) 和Bretz修改的RMNPI (RMNPI-Bretz) 评分与实际斑块数量之间的相关性.
评估这些指数在表示斑块减少方面的准确性.
开发一种方法来提高口腔卫生研究数据的解释性.

主要方法:

30名参与者在72小时内不进行口腔卫生,然后习惯性刷牙.
内口扫描捕获了刷牙后披露的斑块.
评分网格应用于标准化图像,斑块覆盖率以平面度计量 (P%).

主要成果:

所有指数都显示刷牙后斑块显著减少,但程度不同.
布兰德-阿尔特曼分析显示,指数得分与实际斑块覆盖率 (P%) 之间存在系统和比例偏差.
没有观察到线性关系; 导出了转换方程,将指数值与P%联系起来.

结论:

斑块指数仅部分反映了实际的斑块覆盖面.
与RMNPI相比,T-QHPI和RMNPI-Bretz表现出与平面测量测量更接近的一致性.
这些发现强调了传统斑块指数的局限性,并提出了一种方法来改善口腔卫生研究的解释.

关键词:

牙斑块是指牙上的斑块.在口腔内扫描仪.监控监控监控监控平面测量系统的平面测量系统.标记牌指数标记牌指数预防性牙科预防性牙科在RMNPI中,RMNPI是指数.在T-QHPI.

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...

Atherosclerosis I: Introduction

Atherosclerosis I: Introduction

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...
