概括

提取永久第一牙 (P1Ms) 可以导致相邻的牙移动. 这项研究发现,P1M提取导致永久第二 (P2M) 的 mesial 倾斜,无论提取时的P2M化阶段如何.

科学领域:

牙科牙科是指牙科的专业.
矯正牙科矯正牙科是一種矯正牙科.
儿科牙科儿科牙科

背景情况:

永久第一牙的提取 (P1Ms) 是一个常见的正义牙科手术.
提取P1M的时间可以影响牙移动的程度,例如邻近牙的倾斜和旋转.
了解提取时间对永久第二 (P2M) 发育的影响对于治疗规划至关重要.

研究的目的:

根据P2M牙石化阶段,评估儿童的P1M提取结果.
为了比较早期与晚期提取组中P2M的 mesial 倾斜.
确定P1M提取的最佳时间,以最大限度地减少不良影响.

主要方法:

追溯性研究分析了406张7至14岁儿童的全景射线图 (PRs),一次P1M提取.
选择了29名患有治疗前和治疗后PRS的儿童.
根据P2M化,分类为早期提取 (EE) (Nolla等级5-7) 和晚期提取 (LE) (Nolla等级8-10) 组.
使用抽取后PRs测量抽取和反侧面的邻近牙倾斜度.
使用曼·惠特尼U测试进行统计分析 (p < 0.05).

主要成果:

在EE和LE两组中都观察到P2Ms向提取侧的显著月度倾斜趋势 (p > 0.05).
在LE组中,抽取和逆侧侧之间没有发现上P2M mesial倾斜的统计学上显著差异.
该研究表明,P2M提取时不论化阶段如何,P2M倾斜都会发生.

结论:

基于P2M化的P1M提取的时间,不会阻止P2M的 mesial 倾斜.
牙年龄评估对于确定理想的提取时间至关重要,以确保适当的闭塞维护.
可能需要进一步的研究来探索影响P2M运动后提取的其他因素.

关键词:

Teeth

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...
