牙美白化学物质显著削弱了正义牙科支架结合力的强度. 更高的度,比如35%的过氧化,会导致更大的键损失,影响治疗计划.
科学领域:
- 牙科材料科学 牙科材料科学
- ортодонтическая治疗疗效的疗效 ортодонтическая治疗疗效的疗效
背景情况:
- 使用漂白剂来美白牙在正治疗前或治疗期间是常见的.
- 漂白化学品对正义牙科支架键强度的影响是一个重大的临床问题.
研究的目的:
- 在实验室中研究10%的碳胺过氧化物和35%的过氧化对牙科支架的剪切键强度的影响.
- 为了比较不同的漂白处理后的结合强度和失败模式.
主要方法:
- 60个人类前被分为三个组:对照组,10%的碳胺过氧化物和35%的过氧化.
- 在漂白后将正牙支架粘合在一起,并使用通用测试机器测量剪接粘合强度.
- 粘附残留指数 (ARI) 用于评估故障模式;ANOVA和Tukey测试分析了数据.
主要成果:
- 平均切割键强度为18.5 MPa (对照),14.3 MPa (10%的碳酸过氧化物) 和11.7 MPa (35%的过氧化).
- 所有组都显示出显著的差异 (P < 0.05),其中35%的过氧化导致最弱的键.
- 与白化组相比,对照组的ARI评分表明,对照组的牙上有更多的粘合剂残留物.
结论:
- 漂白化学物质显著降低了正义牙科支架键的强度,其效果取决于剂量.
- 临床医生应考虑在漂白后延迟支架粘合或使用质粘合增强策略.

Chemical Bonds
Atoms participate in a chemical bond formation to acquire a completed valence-shell electron configuration similar to that of the noble gas nearest to it in atomic number. Ionic, covalent, and metallic bonds are some of the important types of chemical bonds. Bond energy and bond length determine the strength of a chemical bond.
Types of Chemical Bonds
An ionic bond is formed due to electrostatic attraction between cations and anions. Often, the ions are formed by the transfer of electrons...

Alkyl Halides
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...
