概括
受影响的第三,特别是完全受骨影响时,经常会导致相邻的第二的外部根再吸收 (ERR). 口腔与ERR部位的沟通增加了感染风险.
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:
- 外部根吸收 (ERR) 是一种影响牙的病理过程.
- 受影响的第三牙是邻近牙中ERR的已知风险因素.
研究的目的:
- 为了描述形束计算机断层扫描 (CBCT) 发现,与受影响的第三关节相关的第二关节的外部根再吸收 (ERR).
- 确定影响ERR严重程度和发生的因素.
主要方法:
- 在52名患者中,分析了69名第二牙,其ERR是由受影响的第三牙引起的.
- 使用CBCT来评估受影响的第三关特征 (位置,角度,近距离) 以及它们与相邻第二关中ERR程度的相关性.
主要成果:
- 大的第二牙最受ERR影响.
- 近一半的ERR病例扩展到脉腔,其中24.6%与口腔沟通.
- 第三个牙的完整骨损伤与更深的ERR相关,并且与ERR部位的口腔沟通增加了疼痛.
结论:
- 第三牙的低水平和完整的骨损伤是第二牙ERR的重要贡献者.
- 与口腔沟通的ERR部位具有高感染风险.

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...

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...
