概括
高化物牙膏 (5000 ppm F) 有效地使老年人根病变 (RCL) 失活,在两年内保持不活. 这与1450 ppm F形成鲜明对比,它显示出更可变的损伤活性和重新激活.
科学领域:
- 牙科研究 牙科研究
- 老年牙科老年牙科的牙科.
- 卡里斯管理 卡里斯管理
背景情况:
- 根病变 (RCLs) 在老年人中构成了重大挑战.
- 评估牙膏中不同化物度的有效性对于管理RCL至关重要.
研究的目的:
- 为了比较使用1450 ppm F和5000 ppm F牙膏治疗的根病变 (RCL) 的活性模式.
- 评估在社区居住的老年人中病变失活的长期稳定性.
主要方法:
- 利用了一项随机对照临床试验的数据,该试验涉及两年来2071名RCL.
- 应用了Modified Nyvad的标准来对基线,一年和两年的病变活动进行分类.
- 采用双变量分析,Cochrane Q测试和混合后勤回归来分析活动模式.
主要成果:
- 5000 ppm F牙膏导致了持续的无活化:64%的活跃病变变不活跃并保持不活跃 (A-I-I),30%的病变保持不活跃 (I-I-I).
- 1450 ppm F显示了可变的模式:只有17.8%的人遵循A-I-I,20.4%的人保持I-I-I,其他人在活动和不活动之间波动.
- 较高的化物度 (5000 ppm F) 与1450 ppm F相比,显著降低了损伤的重新激活.
结论:
- 5000 ppm F牙膏促进老年人中RCLs的稳定和一致的无活化.
- 更高的化物度提供更有效和可预测的根的长期管理.
- 这些发现支持使用高化物牙膏来加强老年人群中根的控制.

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...
