概括
过去的注射表明,与内牙插头和NaviTip相比,母牙的闭塞质量更好. 这种技术使得堵塞体积的百分比最高,空隙最少,确保了更好的内牙治疗结果.
科学领域:
- 儿科牙科 儿科牙科
- 牙周内科医院 牙周内科医院 牙周内科医院
- 牙科材料科学 牙科材料科学
背景情况:
- 在初级牙中成功的内牙治疗依赖于有效的生物机械准备和高质量的遮.
- 堵塞材料和插入技术的选择显著影响治疗的成功.
研究的目的:
- 评估和比较Pastinject和NaviTip系统与传统的内牙插头的堵塞质量.
- 为了评估这些技术的有效性,在初级下牙中使用氧化尤根醇 (ZOE).
- 使用形束计算断层扫描 (CBCT) 进行阻塞质量的体积分析.
主要方法:
- 99个初级下第二牙被分为三个组 (每组n=33个):内牙插头,NaviTip和Pastinject.
- 用CBCT测量ZOE遮前后的根运河体积.
- 计算了封闭体积 (POV) 和空体积的百分比,并在各组之间进行比较.
主要成果:
- 在POV (p=0.001) 和空体积 (p=0.001) 组之间观察到统计学上显著的差异.
- 过去的注射显示了最高的POV和最低的空体积.
- 在空隙总数 (p=0.491) 或填充程度 (p=0.152) 中没有发现显著差异.
结论:
- 过去的注射是ZOE在母牙中堵塞的最有效的技术,产生堵塞体积的最高百分比.
- 过去注射系统的结果是空虚体积最低,最多的最佳填充通道数量最高.
- 这项研究强调了闭牙技术在初级牙科中取得成功的内牙结局的重要性.

Tooth 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...

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
