概括
在安置后进行根运河再处理可能会改善结果,特别是当初始根填充质量差时. 这项研究发现,在这种情况下,重新治疗显著减少了顶部牙周炎 (AP),这表明它对长期牙健康的价值.
科学领域:
- 牙周内科医院 牙周内科医院 牙周内科医院
- 恢复性牙科 恢复性牙科
背景情况:
- 根管再处理的目的是增强根充满牙的密封.
- 技术重新治疗对顶端牙周炎 (AP) 频率的影响尚不清楚.
研究的目的:
- 在放置后之前,比较在回收与非回收根中的AP频率.
- 评估后处理后根填充质量的变化.
主要方法:
- 对441张根充满牙的X光片进行了回顾性分析.
- 至少对305根根进行5年的随访.
- 使用Periapical Index评估根填充质量,长度和周周状况.
主要成果:
- 总体AP频率为13.8%. 这是AP的总体频率.
- 整体上,在回收 (4.3%) 和非回收 (15.4%) 根之间,AP没有显著差异 (p=0.061).
- 在最初充满质量不足的回退根的AP显著减少 (2.4%对22.9%,p=0.017).
结论:
- 由于技术原因,根运河再处理显著降低了牙的AP频率,而最初的根填充质量不足.

Tooth Anatomy
439
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...

Assessment of the Mouth
178
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.

Teeth
387
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...

Assessment of apical radial pulse

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.

Oral Cavity
596
The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
