概括

源源激活器 (EA) 系统比被动超声波灌 (PUI) 和超 X (UX) 系统少引起根热. 最初的灌温度影响了根温度,但激活时间的影响很小,这表明临床安全.

科学领域:

牙周内科医院牙周内科医院牙周内科医院
牙科材料科学牙科材料科学
生物医学工程生物医学工程

背景情况:

在根管灌激活过程中存在关于牙周组织加热的担忧.
了解灌剂激活的热效应对于患者的安全性和治疗疗效至关重要.

研究的目的:

分析实时的内部和外部根温度变化,使用不同的灌激活系统.
为了评估灌温度,激活系统和持续时间对根温度的影响.

主要方法:

用模拟的根穿孔准备了两个单根前.
热电偶传感器测量了内部和外部根表面的温度.
在25°C或45°C时用2.5%的甲 (NaOCl) 灌,通过被动超声波灌 (PUI),超X (UX) 或内源激活器 (EA) 激活20-60秒.

主要成果:

与PUI和UX相比,内源激活器 (EA) 系统导致温度升高明显较低 (p < 0.05).
在25°C灌温度下,PUI和UX显示了类似的温度变化.
激活持续时间对根温度变化的影响最小.

结论:

最初的灌温度和激活系统显著影响内部和外部根温度.
激活期似乎对根温度的影响微不足道,这表明临床安全性.
在根管灌过程中,EA是潜在的更安全的选择,因为它会产生热效应.

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Responses to Drought and Flooding

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

Responses to Heat and Cold Stress

Responses to Heat and Cold Stress

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.
