概括
在初始牙中,解剖顶部和顶孔之间的差异大大不同,受根曲率和道大小的影响,影响内牙治疗的成功.
科学领域:
- 牙科 牙科是指牙科的专业.
- 牙周内科医院 牙周内科医院 牙周内科医院
- 儿科牙科 儿科牙科
背景情况:
- 主牙的生理再吸收会导致顶部区域的持续变化.
- 顶峰孔 (AF) 可能与解剖顶部 (AA) 不一致,这对内牙治疗构成了挑战.
- 了解差异距离 (DD) 和差异接受 (DA) 是成功进行母牙脉切除术的关键.
研究的目的:
- 在母牙中,研究解剖顶部 (AA) 和顶孔 (AF) 之间的差距 (DD).
- 为了评估母牙的差异接受 (DA).
- 确定根管曲率,再吸收度和管道大小对DD和DA的影响.
主要方法:
- 研究了60颗母牙的180个根通道.
- 使用K-file测量了AA和AF的通道长度.
- 计算DD并进行统计分析以评估显著性 (p < .05).
主要成果:
- 34.4%的运河具有0毫米的DD,而84.4%的运河具有可接受的DD (≤2毫米).
- 在不同的根曲率和道大小组中观察到DD的显著差异.
- 在不同的运河大小组中,DA显示出显著的差异.
结论:
- DD在母牙中表现出广泛的变化,不受再吸收程度的影响.
- 根曲率和通道大小显著影响DD和可接受差异.
- 建议将可接受的差异作为一次性牙脉切除术的标准.

01:21Tooth Anatomy

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...

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
