概括
在根管治疗 (RCT) 期间,下膜神经 (IAN) 损伤的风险在下第二牙的远距离根部较高,特别是在18-25岁的女性中. 这凸显了根茎和下沟 (MC) 之间的解剖学接近的重要性.
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:
- 底摩拉根与底通道 (MC) 之间的距离是预防根管治疗 (RCT) 期间下膜神经 (IAN) 损伤的关键因素.
- 了解这种解剖关系对于下的内牙手术至关重要.
研究的目的:
- 评估MC与下第一个和第二个根尖端之间的距离对IAN损伤风险的影响.
- 为了评估土耳其亚群体中的这些风险.
主要方法:
- 分析了934名患者的圆束计算机断层扫描 (CBCT) 扫描.
- 根尖和MC的上皮层边界之间的最短线性距离是使用偏切口测量的.
主要成果:
- 在18-25岁的年龄组和女性中 (p <0.05) 观察到,和远端根与MC的距离更近.
- 10.5%的 mesial 根和12.2%的远端根显示与MC的密切接触或入侵.
- 3.0%的 mesial 根和2.8%的远端根在MC的1.00毫米之内.
结论:
- 下第二的远距离根在RCT期间具有较高的IAN损伤风险.
- 这种风险在女性患者和18-25岁的患者中特别高.

01:10Computed Tomography
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...

01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

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...
