概括
内牙治疗显著降低了根管牙厚度 (DT),特别是在牙和冠状/中三位. 剩余的牙厚度小于1毫米会增加治疗后并发症的风险.
科学领域:
- 牙科 牙科是指牙科的专业.
- 牙周内科医院 牙周内科医院 牙周内科医院
- 牙科成像 牙科成像 牙科成像
背景情况:
- 剩余的牙厚度 (RDT) 在内牙后治疗计划中至关重要.
- 在内手术后评估RDT变化对于预测治疗结果至关重要.
研究的目的:
- 评估完整的牙和经过内牙治疗的牙的根管牙厚度变化.
- 用CBCT扫描来比较冠状,中间和顶端根三分之一的牙厚度.
主要方法:
- 分析了来自三个年龄组的300张CBCT扫描,比较了前后内牙治疗.
- 测量牙厚度 (DT) 在口腔,面部,远部和舌腔/面部壁.
- 具有p < 0.05.05的显著程度的统计分析.
主要成果:
- 在完整的牙和经过内牙治疗的牙之间观察到牙厚度的显著差异 (p < 0.05).
- 在牙厚度上没有发现与年龄相关的显著差异 (p > 0.05).
- 下犬的冠状三分之一显示出最少的牙损失 (4.2%).
结论:
- 与顶端三分之一相比,牙厚度在冠状和中间根三分之一显著下降.
- 牙经历了最显著的牙体积损失,RDT往往低于1毫米.
- 减少RDT增加了后期准备期间并发症的风险.

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...

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
