概括
在研究根管密封的电热载体温度时,这项研究在使用连续波凝结 (CWC) 技术与生物陶密封剂时,在120°C和200°C之间没有发现细菌泄漏的显著差异.
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:
- 根通道堵塞的目的是实现密封密封,以防止细菌进入.
- 连续波凝结 (CWC) 技术被广泛用于根管填充.
- 生物陶密封剂在密封性能和生物相容性方面具有潜在的优势.
研究的目的:
- 评估电热载体温度对根管堵塞疗效的影响.
- 为了确定在使用CWC技术的生物陶密封器时,不同温度 (120°C与200°C) 是否会影响细菌泄漏.
主要方法:
- 一个ex vivo研究使用了92个取的单根牙接受了内牙治疗.
- 牙被用Endoseal MTA生物陶密封剂使用CWC技术在120°C或200°C时遮.
- 细菌泄漏在40天内使用标准化模型进行评估,并通过日志等级测试进行比较.
主要成果:
- 平均细菌泄漏生存率为120°C组的39.0天,200°C组的34.0天.
- 在两个温度组之间没有观察到细菌泄漏的统计学上显著差异 (p=0.612).
结论:
- 测试的电热载体温度 (120°C和200°C) 并没有显著影响细菌泄漏.
- 在这个范围内的电热载体温度的选择似乎不是CWC技术对Endoseal MTA的密封能力的关键因素.

Assessing Body Temperature - Oral
722
Here are the steps to accurately measure oral temperature using an electronic thermometer:
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...

Bacterial Signaling
31.4K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...
