概括
大多数下第三位于下通道的口腔上. 圆束计算机断层扫描 (CBCT) 揭示了第三位和下膜神经附近之间的显著联系,这对外科计划至关重要.
科学领域:
- 牙科 牙科是指牙科的专业.
- 口腔和牙面部外科手术
- 放射学 放射学是一门学科.
背景情况:
- 下膜神经损伤通常与下管道和第三牙之间的空间关系有关.
- 了解这种解剖学对于防止牙科手术期间神经损伤至关重要.
研究的目的:
- 为了分类下第三和下通道之间的三维解剖关系.
- 分析下膜神经通道和下神经之间的接触和非接触关系.
主要方法:
- 一项横截面研究分析了100张圆束计算机断层扫描 (CBCT) 扫描.
- 下沟与第三根相对的位置被分类为 (口腔,舌头,顶端,根际).
- 通过统计分析 (千平方试验),确定了状位置与神经通道接触之间的关联.
主要成果:
- 下管最常出现在第三的口腔侧 (45.0%).
- 顶端 (26.0%) 和根间 (23.0%) 的位置也很常见,语言侧的位置很少 (6.0%).
- 在第三位和下管附近之间发现了显著的关联 (p<0.001),特别是在语言和根际病例中.
结论:
- 大多数下第三牙与下通道有口腔关系.
- 在第三的位置和下管道之间存在显著的解剖关系,影响手术风险.

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...
