概括
拥抱湿Bond (EWB) 密封剂有效地防止了牙的,即使在潮湿的条件下. 保持率在12个月内下降,但在湿度控制和非湿度控制的设置之间仍然可比.
科学领域:
- 牙科 牙科是指牙科的专业.
- 牙科材料 牙科材料
- 预防性牙科 预防性牙科
背景情况:
- 洞穴和裂密封剂对于新爆发的永久性牙的虫预防至关重要.
- 密封剂应用期间的水分污染可能会损害保留和有效性.
- 拥抱WetBond (EWB) 是一种耐湿的树脂基密封剂,专为具有挑战性的临床环境而设计.
研究的目的:
- 评估和比较EWB密封剂在受湿度控制和非受湿度控制的条件下永久性牙中的保留率和防腐蚀有效性.
- 为了评估12个月的长期密封剂性能.
主要方法:
- 这是一项分口随机对照试验,涉及37名有双侧非腔的学龄儿童 (6-14岁).
- 在两个条件下应用EWB密封剂:湿度控制 (I组) 和非湿度控制 (II组).
- 使用修改后的USPHS标准对密封剂的保留,皮肤腐烂的预防和其他参数进行评估.在1,6和12个月.
主要成果:
- 在两组中,密封剂的保留率从1个月大幅下降到12个月 (I组:96.4%至49%;II组:96.4%至54.9%).
- 两组之间没有观察到保留率的显著差异 (p > 0.05).
- 虫发病率很小 (12个月后2%),除保留外,其他密封剂参数没有显著恶化.
结论:
- 洞穴和裂密封剂,包括耐湿的EWB,在防止闭口的过程中是有效的,无论应用过程中的湿度控制如何.
- 在受控和不那么受控的湿度设置中,EWB表现出可比的性能,强调其适用于现实世界的临床实践和公共卫生倡议的适用性.

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.

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...

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...

01:10Moisture Content and Bulking of Aggregate
425
The moisture content of aggregates is a crucial factor in construction, particularly in concrete mixing, as it influences the total water required in the mix. Moisture content represents the water coated on the exterior surface of the aggregate existing in a saturated and surface-dry condition. The total water content of a moist aggregate is the sum of its moisture content and water absorption.
When aggregates are exposed to rain or sit in stockpiles, they absorb moisture, which must be...

01:12Trial 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...

01:04Random Error
9.1K
Random or indeterminate errors originate from various uncontrollable variables, such as variations in environmental conditions, instrument imperfections, or the inherent variability of the phenomena being measured. Usually, these errors cannot be predicted, estimated, or characterized because their direction and magnitude often vary in magnitude and direction even during consecutive measurements. As a result, they are difficult to eliminate. However, the aggregate effect of these errors can be...
