ортодонтических设备的铁离子在口腔面膜中比语言面膜积聚更多. 这表明了不同的同化机制,并强调了在治疗后需要量身定制的牙护理策略.
科学领域:
- 口腔健康 口腔健康
- 生物材料科学 生物材料科学
- 牙科研究 牙科研究
背景情况:
- 口腔中的微量金属会影响质的特性.
- 来自正牙器械的金属可能会影响牙面膜的完整性,但机制尚不清楚.
研究的目的:
- 为了研究是否来自正牙器件的铁 (Fe) 离子优先融入口腔或舌腔膜.
- 了解人类质中的不同金属同化.
主要方法:
- 在体外模拟12个月的正牙器械磨损在人类的牙.
- 使用激光切除-感应合等离子体质谱法 (LA-ICP-MS) 分析语言口面的截面.
- 应用了周期性pH值波动;排除了细菌和酶作用.
主要成果:
- 随着时间的推移,铁度在质中增加.
- 与语言侧相比,在口腔面膜上观察到明显更大的Fe积累和更深的透.
- 口腔Fe的增加与 (Ca) 的减少相关,而最终的Fe水平与两边的初始 (Zn) 相相关.
结论:
- 牙口面膜表现出更大的易感性铁离子同化来自正牙器件,与语言面膜相比,具有不同的机制.
- 建议进一步研究Fe和Zn在 ортодонтика后治疗改变中的作用.
- 试管婴儿的方法可以帮助优化牙保护策略.

Assessing Body Temperature - Oral
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...
