まとめ
35%過酸化水素(HP)漂白後に使用されたプロポリス抽出物は、歯科エナメル質に悪影響を及ぼさなかった。この天然薬剤は、歯のホワイトニング効果を維持し、エナメル質の表面粗さとマイクロ硬度を保護した。
科学分野:
- 歯科材料科学;生体材料研究;口腔衛生
背景:
- 高濃度の過酸化水素(HP)を用いた歯の漂白は、歯科エナメル質の特性を変化させる可能性がある。
- 漂白の潜在的な悪影響を軽減するためには、保護剤の調査が重要である。
研究 の 目的:
- 35%HP漂白後の歯科エナメル質に対するプロポリス抽出物の影響を評価すること。
- プロポリスがウシエナメル質の色の変化、表面粗さ、およびマイクロ硬度に及ぼす影響を評価すること。
主な方法:
- 60個のウシエナメル質標本を、対照群およびHP漂白、脱感作剤、フッ化物、プロポリス抽出物の様々な組み合わせを含む6群に分けた。
- 漂白前および漂白24時間後の色の変化(ΔE*, ΔE00, ΔWID)、表面粗さ(Ra)、およびマイクロ硬度(KHN)を評価した。
主要な成果:
- すべてのHP処理群で、対照群と比較して有意な色の変化が認められた。;漂白により表面粗さが増加したが、プロポリスおよび脱感作剤処理によりこの効果は軽減された。;HP、脱感作剤、およびプロポリスの組み合わせは、対照群と同等のエナメル質のマイクロ硬度を維持した。
結論:
- プロポリス抽出物は、35%HPのホワイトニング効果を損なわない。
- プロポリス抽出物は歯科エナメル質に対して保護効果を示し、表面粗さとマイクロ硬度に対する有意な悪影響を防ぐ。

Physical Properties Affecting Solubility

Solutions of Gases in Liquids
As for any solution, the solubility of a gas in a liquid is affected by the attractive intermolecular forces between solute and solvent species. Unlike solid and liquid solutes, however, there is no solute-solute intermolecular attraction to overcome when a gaseous solute dissolves in a liquid solvent since the atoms or molecules comprising a gas are far separated and experience negligible interactions. Consequently, solute-solvent interactions are the sole...

Physical Properties of Alkanes
14.5K
Alkanes are nonpolar molecules due to the presence of only carbon and hydrogen atoms. The electronegativity difference between carbon and hydrogen is minimal, and hence alkanes have a zero dipole moment. This leads to the presence of only dispersion forces between the molecules. The strength of dispersion forces is dependent on the surface area of the molecules on which they act. Since the surface area increases with the molecular length for straight-chain alkanes, the dispersion forces also...

Physical Properties of Ethers

Overview
An ether molecule has a net dipole moment due to the polarity of C–O bonds. Subsequently, boiling points of ethers are lower than those of alcohols of comparable molecular weight and slightly higher than those of hydrocarbons of comparable molecular weight (Table 1).
Ethers can act as hydrogen bond acceptors, making them more water-soluble than hydrocarbons, but since ethers cannot act as hydrogen bond donors, they are much less soluble in water than alcohols. Ethers are considered...

Physical Properties of Amines
4.2K
Amines with low molecular weight are usually gaseous at room temperature, while those with high molecular weight are liquid or solids in nature. Usually, low molecular weight amines have a rotten fish-like smell. Diamines typically have a pungent smell. For instance, cadaverine and putrescine, depicted in Figure 1, are two molecules responsible for decaying tissue.
