概括
甲Pro漆表现出最长的化物释放时间用于虫预防,其次是Enamelast和Fluor Protector漆. 这项研究比较了三种不同漆的化物释放寿命.
科学领域:
- 牙科科学 牙科科学
- 皮肤病学 皮肤病学 皮肤病学
- 材料科学 材料科学 材料科学
背景情况:
- 牙损是一种动态的过程,涉及去矿化和重矿化.
- 化物应用会改变这种平衡,有助于预防.
- 化物漆提供长时间的治疗效果,并且耐受性很好,特别是在儿科和特殊需求人群中.
研究的目的:
- 为了评估和比较三种不同的化漆释放的化物长寿:保护剂,化和化Pro.
- 为了确定哪种化物漆提供了最持续的化物释放随着时间的推移,以有效预防.
主要方法:
- 72个健康的永久前牙被分为四组 (每组n=18个).
- 三组接受了Fluor Protector,Enamelast或Enamel Pro漆的应用,其中一组作为对照.
- 标本在pH值7.2的人工唾液中储存,在1,3个月和6个月后分析化物释放.
主要成果:
- 保护剂 (1.5%化) 的释量最少 (0.03 ± 0.0 ppm).
- 埃纳梅拉斯特 (5%的化) 显示持续释放化物,在6个月后达到0.16±0.06 ppm.
- 在Enamel Pro (5%的化与ACP) 中,最初释放的化物最多 (0.32 ± 0.08 ppm在3个月),但在6个月 (0.09 ± 0.03 ppm) 释放的化物比Enamelast少.
结论:
- 乳Pro漆表现出高超的化物释放寿命长达3个月.
- 在6个月的研究期间,乳漆在6个月的研究期间提供了一致的化物释放.
- 基于持续的化物释放,Enamel Pro,Enamelast和Fluor Protector漆是建议使用的,以此顺序用于预防.

Radioactive Decay and Radiometric Dating
34.6K
Radioactivity is a spontaneous disintegration of an unstable nuclide and is a random process, as all the nuclei in the sample do not decay simultaneously. The number of disintegrations per unit time is called the activity (A), which is directly proportional to the number of nuclei in the sample. The decay constant (λ) is an average probability of decay per nucleus in unit time.

Toxicity Testing in Animals
204
Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...
