概括
高强度的LED固化灯,如木,可以在正牙粘合过程中增加室的热量,可能导致轻微的炎症. 这些热效应似乎大多是可逆的,但持续的升高可能会刺激牙皮质.
科学领域:
- 牙科学
- 生物材料科学
- 牙整形
背景情况:
- 在正牙科中,发光二极管 (LED) 固化装置可能会导致脉腔的热变化.
- 过度的热量可能会导致脉炎症或损伤,根据固化光的类型和功率而有所不同.
- 了解这些热效应对于预防阳性脉损伤至关重要.
研究的目的:
- 通过不同的LED固化灯在正牙粘合过程中量化热量.
- 评估脉组织中所产生的组织病理变化.
- 要将光强度与热效应和脉反应相关联.
主要方法:
- 使用了42个人类前,分为组织学和热学评估组.
- 在硬化前和后使用热电偶测量了纸室的温度变化.
- 组织病理学评估评估了脉炎症;统计分析包括基平方和ANOVA.
主要成果:
- 木LED单元 (B组) 显示轻度至中度的脉炎症 (p=0. 047).
- 虽然在两组之间没有统计学上的显著性 (p=0.064),但E组 (木热) 的温度上升是最高的 (2.586°C).
- 在硬化前和硬化后的温度有显著的变化 (p<0. 011),其中3M Unitek的值更高.
结论:
- 高强度的LED固化灯, 特别是木单元, 产生更多的热量, 可能导致早期的炎.
- 观察到的脉变化在很大程度上是可逆的.
- 持续的温度升高超过5. 5°C可能是脉刺激的值.

01:10Electrical Energy
Using electric appliances for a longer period of time consumes more electrical energy and results in a higher electric bill. The energy produced by the transfer of electrons from one point to another is known as electrical energy. If power is delivered at a constant rate, the electrical energy can be defined as the product of power used by the device for a period of time. The energy unit on electric bills is the kilowatt-hour, where one kilowatt-hour is equivalent to 3.6 × 106 joules. The...
01:16Biasing of P-N Junction
The operation of a p-n junction diode involves various biasing conditions, including forward bias, reverse bias, and equilibrium.
In equilibrium, no external voltage is applied across the p-n junction. The depletion region is formed at the junction interface due to the diffusion of carriers, which leaves behind charged dopants, acceptors on the p-side, and donors on the n-side. These immobile charges create an electric field that prevents further diffusion of carriers. The related energy band...
