概括
银胺 (SDF) 有效地使牙重矿化. 与其他SDF配方相比,SDF优势逮捕显示出优异的微硬度,表明用于治疗早期的增强质.
科学领域:
- 牙科学
- 生物材料科学
- 脏病学
背景情况:
- 牙腐烂是主要牙和永久牙的常见问题.
- 早期的面膜去矿化可以通过重矿化来逆转.
- 银胺 (SDF) 广泛用于预防虫并阻止疾病的进展.
研究的目的:
- 为了比较三种商业38%白银二化物 (SDF) 配方对母牙的人造质损伤的重矿效应.
- 使用pH循环模型评估不同SDF组合对乳液微硬度的影响.
- 测试不同的商业SDF配方具有不同的重矿效应的假设.
主要方法:
- 七十五个主要牙被分为五组:基线,三种38%的商用SDF配方 (Riva Star Aqua,Riva Star,Advantage Arrest) 和一个对照组.
- 使用脱矿化溶液 (pH4. 5) 创建了人工病变,持续了三天.
- 在pH循环后进行维克斯微硬度测试,并使用ANOVA和Tukey的后期测试分析数据.
主要成果:
- 在SDF组中观察到微硬度的显著差异 (F=167.73, p<0.001).
- 与SDF Riva Star Aqua和SDF Riva Star相比,SDF Advantage Arrest的平均微硬度显著更高 (p<0. 001).
- 在SDF Riva Star Aqua和SDF Riva Star之间没有发现显著的微硬度差异 (p=0. 388).
结论:
- 在经过测试的SDF配方中,SDF Advantage Arrest在增加质微硬度方面表现出卓越的表现.

01:24Drugs for Peptic Ulcer Disease: Sucralfate as Mucosal Protective Agents
2.3K
In the intricate landscape of the gastric lumen, excessive acid secretion disrupts the natural defense mechanisms, weakening the mucus-bicarbonate barrier. This vulnerability allows pepsin to infiltrate epithelial cells, digesting mucosal proteins and triggering erosion, leading to ulcer formation.
In this scenario, mucosal protective agents like sucralfate play an essential role. Sucralfate, a complex of sulfated sucrose and aluminum hydroxide, demonstrates its usefulness in acidic conditions,...

01:29Drugs for Treatment of Ulcerative Colitis in IBD
705
Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...
