まとめ
発泡錠剤による義歯洗浄は、時間とともにカンジダ付着を効果的に減少し、アクリル樹脂表面の粗さを改善した。電解水は表面の粗さに対して可能性を示したが、カンジダ除去には効果が低く、長期的な義歯衛生には化学洗浄が最適であった。
科学分野:
- 歯科材料科学
- 微生物学
- 表面科学
背景:
- 義歯の衛生状態は口腔衛生にとって重要であり、アクリル樹脂表面の粗さはカンジダ・アルビカンスの付着を増加させる可能性があります。
- 様々な洗浄方法が義歯表面特性に及ぼす長期的な影響を調査する必要があります。
研究 の 目的:
- アクリル樹脂の表面粗さとカンジダ付着に対する異なる義歯洗浄手順の影響を比較すること。
- 化学的、機械的、および電解水洗浄方法の効果を評価すること。
主な方法:
- 3種類のアクリル樹脂材料を、最大90日間、4つの洗浄方法(蒸留水、発泡錠剤、ブラッシング、電解水)に供した。
- 表面粗さは接触式触針形状測定機を用いて測定し、カンジダ付着はコロニー形成単位(CFU/mL)で定量化した。
主要な成果:
- 義歯洗浄手順は、30日および90日後にすべての種類のアクリル樹脂の表面粗さを有意に減少させた。
- アルカリ性過酸化物ベースの発泡錠剤は、試験したすべての樹脂材料でカンジダ付着を有意に低下させた。
- 電解水は表面粗さに影響を与えたが、発泡錠剤と比較してカンジダ付着に対する効果は低かった。
結論:
- 義歯洗浄錠剤による化学洗浄は、表面粗さとカンジダ付着の両方を効果的に管理する、長期的な義歯衛生のための最適な方法である。
- 電解水は表面粗さの改善のための実行可能な代替手段となる可能性があるが、カンジダ除去のためには改良が必要である。

Adhesion

Adhesion occurs when one type of molecule is attracted to a different molecule. Water exhibits adhesive properties in the presence of polar surfaces, such as glass or cellulose in plants. For instance, when water is poured into a glass, the positively charged hydrogen molecules of water are more attracted to the negatively charged oxygen molecules in the silica than to the oxygen in neighboring water molecules.

Cleaning, Sterilization, and Disinfection
10.4K
Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

Factors Affecting Dissolution: Particle Size and Effective Surface Area
1.7K
Dissolution kinetics, an essential aspect of oral drug delivery, is significantly influenced by the drug's particle size. According to the Noyes-Whitney dissolution model, the dissolution rate correlates directly with the drug's surface area. The larger the surface area, the higher the drug's solubility in water, leading to a faster drug dissolution rate. Reducing particle size increases the effective surface area, enhancing the dissolution process. Micronization and nanosizing are...

Surface Tension
The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...

Cell Adhesion in Plants
3.3K
Plants have rigid cell walls that are made up of cell wall polysaccharides that mediate cell-cell adhesion. The primary cell walls of plants consist of two independent and interacting polysaccharide networks: a pectin matrix that embeds the second network comprising cellulose and hemicelluloses.

Buffer Effectiveness
55.2K
Buffer solutions do not have an unlimited capacity to keep the pH relatively constant . Instead, the ability of a buffer solution to resist changes in pH relies on the presence of appreciable amounts of its conjugate weak acid-base pair. When enough strong acid or base is added to substantially lower the concentration of either member of the buffer pair, the buffering action within the solution is compromised.
The buffer capacity is the amount of acid or base that can be added to a given volume...
