概括
经过内牙治疗的牙 (ETT) 在正义牙科治疗期间显示出较少的外部顶端根再吸收 (EARR),而不是重要的脉牙 (VPT). 这表明ETT可以安全地移动,即使采用提取或多相处理.
科学领域:
- 矯正牙科 矯正牙科是一種矯正牙科.
- 牙周内科医院 牙周内科医院 牙周内科医院
- 牙科放射学 牙科放射学
背景情况:
- 外部角根再吸收 (EARR) 是正牙治疗的潜在并发症.
- 在正义牙运动期间,内牙治疗牙 (ETT) 的行为需要进一步调查.
- 通过比较ETT中的EARR与重要肉质牙 (VPT) 的EARR,可以为治疗安全协议提供信息.
研究的目的:
- 评估和比较在正治疗后ETT和逆侧VPT中EARR的发生率和严重程度.
- 调查EARR与牙科治疗变量之间的相关性,例如类型,持续时间,患者年龄和性别.
主要方法:
- 从503名接受正牙治疗的患者的全景放射图的回顾分析.
- 测量牙长度和计算ETT和VPT治疗前和治疗后的EARR百分比.
- 使用曼-惠特尼U,威尔科克森签名等级,克鲁斯卡尔-瓦利斯和斯皮尔曼相关性测试进行统计分析.
主要成果:
- 在所有正牙治疗组中,在ETT和VPT之间观察到EARR的统计学上显著差异 (p<0.05).
- EARR与牙科治疗的持续时间和类型 (例如,双相提取) 有积极的相关性,但不受患者年龄或性别的影响.
- 显著的EARR发生在两相提取组的ETT和VPT中,以及在单相提取组的VPT中.
结论:
- 经过内牙治疗的牙在正牙治疗期间,与关键的肉质牙相比,表现出明显较少的外部角根再吸收.
- 这些发现支持牙科内科治疗牙的正义运动的安全性,即使在复杂的治疗场景中.
- ортодонтика治疗持续时间和提取协议是影响ETT和VPT中EARR的重要因素.

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...
