概括

与冷侧压缩 (CLC) 和温暖垂直压缩 (WVC) 相比,热塑化注射性肠膜 (TIGP) 显著减少了根通道中的微生物泄漏. TIGP提供卓越的密封,以提高内牙治疗寿命.

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
微生物学微生物学

背景情况:

内牙治疗的成功取决于有效的密封,以防止微生物泄漏.
在防止微生物透方面,各种堵塞技术的有效性受到争议.
实现无透密封对于长期内牙科结果至关重要.

研究的目的:

为了比较三种根管封闭技术的微生物泄漏阻力.
为了评估热塑化注射性高达 (TIGP) 对冷侧压缩 (CLC) 和温暖垂直压缩 (WVC) 的有效性.

主要方法:

使用ProTaper通用系统准备了60个人类下前.
使用CLC,WVC或TIGP (每种n=20) 进行牙堵塞.
用Enterococcus faecalis的双室微生物泄漏模型在60天内被使用.

主要成果:

TIGP显示微生物泄漏最少 (平均泄漏时间:49.8天).
WVC显示中等泄漏 (44.3天),而CLC泄漏最多 (32.5天).
在30%的TIGP,60%的WVC和85%的CLC样本中发生了泄漏 (P <0.01).

结论:

与CLC和WVC相比,热塑化注射性gutta-percha提供了优越的微生物抗泄漏能力.
TIGP是一种有前途的技术,可以提高内牙治疗的寿命.
临床应用TIGP可以提高密封能力,减少治疗失败.

关键词:

寒冷的侧向压缩方式肠球菌 (enterococcus faecalis) 是一个可怕的病原体.微生物泄漏可能是微生物泄漏.根运河堵塞根运河堵塞热塑性质的Gutta-Percha可以使用.温暖的垂直压缩热的垂直压缩.
