概括

这项研究发现,单和Thermafil®技术都有效地堵塞了侧面根通道,冠状管道比尖端更成功. 古塔珀卡和密封剂的结合提高了填充率,特别是在顶端道.

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

背景情况:

侧侧根通道对于内牙治疗的成功至关重要.
侧腔通道的病理过程需要有效的内牙干预.
侧面通道的堵塞仍然是根管治疗中的挑战.

研究的目的:

为了比较单和Thermafil®堵塞技术在填充侧根通道中的有效性.
为了评估gutta-percha和密封剂对侧面通道堵塞的影响.
为了评估冠状管与尖端侧面通道的填充率.

主要方法:

通过使用ProTaper Next®旋转文件,准备了带有冠状和顶端侧面通道的人工根管块.
使用单技术 (gutta-percha/AH Plus Bioceramic®密封剂) 或Thermafil®技术 (AH Plus®密封剂) 进行了样本封闭.
进行了放射和摄影分析,以评估侧面通道填充.

主要成果:

总体而言,侧腔通道堵塞成功率为73%.
冠状侧面通道的填充率为90%,而顶部通道的填充率为56.7%.
单和Thermafil®技术之间没有发现显著差异,尽管Thermafil®趋向于更好的顶端填充.

结论:

这两种技术在侧面通道堵塞方面表现出相似的有效性.
冠状侧面通道比顶端通道更容易填充.
古塔珀卡和密封剂的组合提高了堵塞的有效性,特别是在角侧面通道.

Thermal Insulation in Masonry Walls

Thermal Insulation in Masonry Walls

In hot, dry climates, the thermal mass of masonry walls can be beneficial, absorbing heat during the day and releasing it at night, thereby stabilizing indoor temperatures. However, in most other climates, additional insulation is necessary to enhance thermal resistance.
External insulation can be applied using an Exterior Insulation and Finish System (EIFS), which involves affixing panels of plastic foam to the wall and covering them with a polymeric stucco reinforced with glass fiber mesh....
