概括
圆束计算机断层扫描 (CBCT) 比全景放射 (PAN) 更有效地检测来自保留的第三 (M3) 的外部根吸收 (RR). 年龄较大, mesial 倾向和 M3 的更深层保留预测了 RR 严重程度的增加.
科学领域:
- 牙科 牙科是指牙科的专业.
- 口腔和面放射学 口腔和面放射学
- 牙科成像 牙科成像 牙科成像
背景情况:
- 保留的第三 (M3) 经常与相邻的第二 (M2) 的外部根吸收 (RR) 相关.
- 准确的RR诊断对于治疗计划和预防并发症至关重要.
- 全景放射 (PAN) 是一种常见的初始成像方式,但其检测RR的灵敏度可能有限.
研究的目的:
- 估计由保留的第三 (M3) 引起的外部根吸收 (RR) 的患病率和严重程度.
- 为了比较全景放射学 (PAN) 和形束计算断层扫描 (CBCT) 的诊断灵敏度,用于RR.
- 确定与M2根再吸收的发展和严重程度相关的预测因素.
主要方法:
- 对367名患有PAN和CBCT成像的患者进行了回顾性横截面分析.
- 预测变量包括患者年龄,性别,M3倾向,保留深度和M2接触水平.
- 结果变量是M2根再吸收,使用既定的标准进行分级,根据PAN发现进行分组分析.
主要成果:
- CBCT显示RR在20%的M2与保留的M3相邻,而PAN则表明RR在5%以下.
- 增加RR严重性的预测因素包括M3的 mesial倾向,老年患者的年龄和更深的M3保留.
- 在PAN没有表现出病理性的情况下,CBCT确定了RR.
结论:
- 在诊断与第三关节相关的外部根吸收时,PAN表现不佳.
- CBCT是检测RR的更敏感的工具,特别是在老年患者的半角角和深度保留M3的情况下.
- 研究结果支持在怀疑RR或在PAN不确定的情况下考虑CBCT进行第三骨提取手术规划.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

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...
