概括
受到冲击的下第三,特别是半角,显著增加了相邻第二的远端脏的风险. 圆束计算机断层扫描 (CBCT) 显示了这种关联,这表明早期干预可能是有益的.
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
- 牙科公共卫生 牙科公共卫生
背景情况:
- 被冲击的下第3关节与诸如皮炎,根吸收和相邻第二关节的远端脏等并发症有关.
- 沙特阿拉伯的先前研究使用了二维成像,可能低估了诊断特征.
- 圆束计算机断层扫描 (CBCT) 提供了先进的可视化,用于评估受影响的牙和相关的.
研究的目的:
- 评估受影响的第三牙的患病率和模式.
- 用CBCT确定受影响的第三牙和相邻第二牙的远端牙之间的关联.
- 提供有关诊断特征和潜在风险的见解.
主要方法:
- 一项回顾性横截面研究分析了来自沙特阿拉伯Ha'il (2019-2024) 牙科中心的315个CBCT扫描.
- 受影响的第三牙被使用冬季和佩尔和格雷戈里系统分类.
- 在相邻的第二中记录了远端,并使用奇方和费舍尔精确测试进行了统计分析 (p≤0.05).
主要成果:
- 在下部最常见的是半角角冲击,特别是在年轻的成年人 (18-25岁).
- B类和C类冲击和更深的冲击在下上普遍存在,女性和老年人表现出更深的冲击.
- 下第二牙的远端脏与半角和水平冲击有显著的关联 (象限4).
结论:
- 受到冲击的下第三,特别是半角和更深的,显著地危及相邻的第二.
- CBCT成像显示,距离的流行率显著,可能比之前报告的更高.
- 在高风险病例中,可以考虑早期干预和预防性移除,等待进一步的纵向和干预研究以制定最终指南.

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...
