概括
与自我蚀刻方法相比,选择性蚀刻应用通用粘合剂减少了初级牙修复中的微漏. 没有蚀刻的自蚀刻粘合剂显示出最大的间隙形成,表明潜在的长期修复问题.
科学领域:
- 牙科材料科学 牙科材料科学
- 恢复性牙科 恢复性牙科
- 生物材料是一种生物材料.
背景情况:
- 牙修复接口的微漏洞是二次牙和修复失败的主要原因.
- 粘合系统在牙科修复中发挥着至关重要的作用,在牙科修复中实现持久密封.
- 了解不同蚀刻技术对微泄漏的影响对于优化修复程序至关重要.
研究的目的:
- 通过评估牙表面和修复材料之间的间隙形成来评估微漏.
- 为了比较通用和自蚀刻粘合剂的自蚀刻和选择性蚀刻应用方法的有效性.
- 通过光学连贯断层扫描 (OCT) 来研究母牙中不同粘合策略的性能.
主要方法:
- 准备了60颗带有V类腔的初级牙,并根据粘合剂类型和应用方法 (自蚀与选择性蚀) 随机分配到6组.
- 测试了两个通用粘合剂和一个自蚀刻粘合剂.
- 用多酸修饰复合树脂修复腔,通过使用OCT和Image J软件测量牙表面和修复之间的距离来量化微泄漏.
主要成果:
- 对所有测试的粘合剂而言,选择性蚀刻的应用导致差距形成显著减少,而不是自我蚀刻的应用 (p<0.05).
- 没有任何蚀刻步骤的自蚀刻粘合剂在所有组中表现出最高的间隙形成程度 (p<0.05).
- 这些发现表明,选择性蚀刻技术在最小化微泄漏方面具有明显的优势.
结论:
- 建议使用选择性蚀刻步骤的通用粘合剂,而不是自蚀刻粘合剂,以提高多酸修饰复合树脂修复在母牙的寿命.
- 需要进一步的临床研究来证实这些发现的长期预后.
- 在这种情况下,选择性蚀刻技术似乎是一个更可靠的方法来实现边缘密封.

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...

Assessment of the Mouth
1.6K
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.
