概括
与激光疗法相比,Fuji TRIAGE玻璃离子密封剂在摩尔切割器低矿化 (MIH) 牙中提供了比激光疗法更好的长期保护,防止摩尔切割器低矿化 (MIH) 牙爆发后分解 (PEB). 这两种治疗方法在18个月的时间内同样有效地预防了脏病的进展.
科学领域:
- 儿科牙科 儿科牙科
- 牙科材料科学 牙科材料科学
- 预防性牙科 预防性牙科
背景情况:
- 牙切割器低矿化 (MIH) 是一种发育性牙缺陷,影响永久牙和切割器.
- MIH使牙容易发生爆发后破裂 (PEB) 和非典型,需要有效的预防策略.
研究的目的:
- 为了比较Fuji TRIAGE玻璃离子密封剂与Er,Cr:YSGG激光疗法 (LT) 在治疗MIH受影响的牙方面的疗效.
- 在18个月的时间内评估MIH儿童的皮进展和PEB的预防.
主要方法:
- 一项随机临床试验,涉及136名儿童 (6-9岁) 患有MIH受影响的牙.
- 牙被分配到激光治疗 (n=68) 或富士试验密封剂 (n=68).
- 包括,PEB和密封剂保留在内的结果在3,6,12和18个月后进行了评估.
主要成果:
- 在18个月内,激光治疗和富士试验密封剂组之间,病进展没有显著差异.
- 在18个月后,与激光疗法相比,Fuji TRIAGE显示PEB的几率明显较低 (OR=1.319,p < 0.001).
- 密封剂的保留随着时间的推移而减少,密封剂的损失与增加PEB风险相关 (OR=2.15,p < 0.001).
结论:
- 与激光疗法相比,Fuji TRIAGE在MIH大中提供了对PEB的优越长期保护.
- 这两种干预措施都在预防病进展方面表现出相似的有效性.
- 密封剂的保留和基线风险因素对于成功预防MIH管理至关重要.

Clinical Trials
10.2K
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.

Clinical Trials: Overview
4.7K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

Molar Mass
86.3K
The identity of a substance is defined not only by the types of atoms or ions it contains but by the quantity of each type of atom or ion. For example, water, H2O, and hydrogen peroxide, H2O2, are alike in that their respective molecules are composed of hydrogen and oxygen atoms. However, because a hydrogen peroxide molecule contains two oxygen atoms, as opposed to the water molecule, which has only one, the two substances exhibit very different properties.

Statistical Software for Data Analysis and Clinical Trials
1.4K
Statistical software is pivotal in data analysis and clinical trials by providing tools to analyze data, draw conclusions, and make predictions. These software packages range from simple data management applications to complex analytical platforms, supporting various statistical tests, models, and simulation techniques. Their significance lies in their ability to handle vast amounts of data with precision and efficiency, enabling researchers to validate hypotheses, identify trends, and make...

Applications of the Ideal Gas Law: Molar Mass, Density, and Volume
63.3K
The volume occupied by one mole of a substance is its molar volume. The ideal gas law, PV = nRT, suggests that the volume of a given quantity of gas and the number of moles in a given volume of gas vary with changes in pressure and temperature. At standard temperature and pressure, or STP (273.15 K and 1 atm), one mole of an ideal gas (regardless of its identity) has a volume of about 22.4 L — this is referred to as the standard molar volume.

Trial and Error and Algorithm
403
A problem-solving strategy is a plan of action used to find a solution. Different strategies have distinct action plans. Trial and error involves trying different solutions until one works. For instance, to fix a broken printer, you might check ink levels, ensure the paper tray isn't jammed, and verify the printer's connection to your laptop. This method can be time-consuming but is commonly used. Thomas Edison, for example, used trial and error to find a suitable filament for the light...
