概括
所有经过测试的6%过氧化 (HP) 漂白产品都显示出有效的牙美白,牙的透率最小,幼虫中没有观察到毒性. 不同的技术显示了可比的漂白效率.
科学领域:
- 牙科材料科学 牙科材料科学
- 生物材料是一种生物材料.
- 毒理学 毒理学 毒理学
背景情况:
- 用过氧化 (HP) 漂白牙是一种常见的美容手术.
- 了解不同HP漂白剂的透率,有效性和毒性对于患者的安全性和治疗结果至关重要.
研究的目的:
- 为了量化氧化 (HP) 透率,漂白效率 (BE) 和各种6%HP漂白技术在幼虫中的毒性.
- 为了比较不同商业6%HP漂白产品的性能.
主要方法:
- 实验室研究涉及60名前分为六组 (n=10),使用不同的6%HP漂白剂 (Pola Luminate,VivaStyle Paint On Plus,PolaDay,White Class,Whiteness HP Automixx) 和对照组.
- 测量了初始HP度和pH值;使用UV-Vis光谱测量评估了HP透到纸腔.
- 用数字光谱仪评估了漂白效率 (ΔE*ab和ΔE00),并在Tenebrio molitor幼虫模型中评估了毒性.
主要成果:
- VivaStyle Paint On Plus,PolaDay和Whiteness HP Automixx的初始HP度低于制造商报告的,而VivaStyle Paint On Plus的pH值更为酸性.
- 与VivaStyle Paint On Plus (p = 0.001) 相比,Pola Luminate和White Class的HP透到纸腔的显著减少 (p = 0.001).与VivaStyle Paint On Plus相比,Pola Luminate和White Class的HP透到纸腔的显著减少.
- 两组之间没有发现漂白效率 (ΔE* ab,p = 0.38; ΔE00,p = 0.42) 的显著差异. 所有测试的6%HP产品对Tenebrio molitor幼虫无毒 (p > 0.05).
结论:
- 所有评估的6%过氧化漂白产品都表现出有效的漂白特性.
- 这些产品在纸腔中透程度有限,对Tenebrio molitor幼虫无毒.
- 在这种体外模型中,选择漂白技术不会显著影响整体漂白效率或毒性.

Hand hygiene
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Antimicrobial Effectiveness
The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...
