概括
木炭美白产品可能会对树脂复合材料的颜色和表面粗性产生负面影响,特别是木炭粉. 常规牙膏和木炭牙膏没有显著地表粗度变化,这表明牙科修复是一种更安全的替代方案.
科学领域:
- 牙科材料科学 牙科材料科学
- 生物材料研究 生物材料研究
- 恢复性牙科 恢复性牙科
背景情况:
- 研究木炭白化剂对牙复合材料的影响对于了解其临床安全性和有效性至关重要.
- 咖啡染色是树脂复合材料常见的外部变色挑战.
- 评估表面粗度的变化对于预测生物膜积累和二次腐烂风险至关重要.
研究的目的:
- 评估各种木炭白化产品对纳米混合树脂复合材料颜色稳定性和表面粗性的影响.
- 为了比较不同木炭配方 (牙膏,溶液,粉末) 与对照和普通牙膏的结果.
- 为了分析模拟咖啡染色和随后用漂白剂刷牙后的变化.
主要方法:
- 五十个Harmonize纳米混合复合树脂样品被分为五组:对照组,Colgate总 (CT),CT+木炭溶液 (CT+CS),Colgate木炭 (CC) 和木炭粉 (CP).
- 标本经历了五天的咖啡浸泡以染色,然后用指定的产品刷刷.
- 颜色变化 (ΔE00) 和表面粗度 (Ra) 在基线,染色后和漂白后进行测量. 扫描电子显微镜 (SEM) 用于表面形态分析.
主要成果:
- 所有组在染色后都表现出显著的颜色变化. 炭粉 (CP) 组在白化后显示出最显著的颜色变化 (ΔE00 = 7.13 ± 1.38).
- 在CT+CS (Ra = 0.57 ± 0.22 μm) 和CP (Ra = 0.54 ± 0.20 μm) 组中,表面粗度显著增加.
- SEM显示了CP处理的明显表面不规则,而普通和木炭牙膏没有显著改变表面粗度.
结论:
- 基于木炭的漂白产品,特别是木炭粉,可能会对树脂复合材料的颜色稳定性和表面完整性产生不利影响.
- 常规牙膏和木炭牙膏配方在表面粗性方面表现出更安全的配置.
- 临床医生应该谨慎地建议在树脂复合材料修复的患者进行积极的木炭美白治疗.

Changes in Skin Color: Clinical Perspectives
4.2K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Plasticizers
464
Water-reducers, or plasticizers, are chemical admixtures used in concrete to improve strength and workability. These additives reduce the water-cement ratio without compromising workability, lower the cement content while maintaining the same workability, or increase workability to assist concrete placement in inaccessible areas.
Plasticizers function by using surface-active agents to create repulsive electrostatic forces between cement particles. This dispersion enhances the concrete's...
