Summary
Fixed dental crowns significantly increase the risk of halitosis, especially when crown margins are defective. Poorly fitted crowns negatively impact oral hygiene and microbial balance, leading to bad breath.
Area of Science:
- Oral Health
- Periodontology
- Dental Biomaterials
Background:
- Halitosis, or bad breath, is a common oral health concern.
- Fixed dental crowns are frequently used in restorative dentistry.
- The relationship between dental restorations and halitosis requires further investigation.
Purpose of the Study:
- To compare halitosis levels in patients with and without fixed dental crowns.
- To explore the influence of specific crown parameters on halitosis.
- To identify risk factors associated with crown placement and oral malodor.
Main Methods:
- 96 subjects (52 with crowns, 44 without) were analyzed.
- Breath samples were analyzed for volatile sulfur compounds (VSCs) using gas chromatography.
- Periodontal and crown parameters were clinically evaluated.
Main Results:
- 52.1% of participants exhibited halitosis.
- Dimethyl sulfide (CH3SCH3) was the most prevalent VSC.
- Fixed crowns showed a significant correlation with halitosis (p < 0.001).
- Defective crown margins (subgingival, over-contoured, open) were linked to increased halitosis prevalence (p < 0.05).
Conclusions:
- Fixed dental crowns are a significant contributing factor to oral halitosis.
- Clinically unacceptable crown parameters exacerbate oral hygiene issues and increase halitosis.
- Dental crown quality and maintenance are crucial for preventing halitosis.

02:33Preparation and Reactions of Thiols
7.1K
Thiols are prepared using the hydrosulfide anion as a nucleophile in a nucleophilic substitution reaction with alkyl halides. For instance, bromobutane reacts with sodium hydrosulfide to give butanethiol.

02:36Crown Ethers
5.7K
Crown ethers are cyclic polyethers that contain multiple oxygen atoms, usually arranged in a regular pattern. The first crown ether was synthesized by Charles Pederson while working at DuPont in 1967. For this work, Pedersen was co-awarded the 1987 Nobel Prize in Chemistry. Crown ethers are named using the formula x-crown-y, where x is the total number of atoms in the ring and y is the number of ether oxygen atoms. The term 'crown' refers to the crown-like shape that these ether molecules...

02:26Preparation and Reactions of Sulfides
5.4K
Sulfides are the sulfur analog of ethers, just as thiols are the sulfur analog of alcohol. Like ethers, sulfides also consist of two hydrocarbon groups bonded to the central sulfur atom. Depending upon the type of groups present, sulfides can be symmetrical or asymmetrical. Symmetrical sulfides can be prepared via an SN2 reaction between 2 equivalents of an alkyl halide and one equivalent of sodium sulfide.

01:29Sulfate Attack on Concrete
457
Sulfate attack on concrete is a deterioration process characterized by a whitish discoloration beginning at the edges and corners, accompanied by cracking and spalling. This phenomenon occurs when sulfates react with the components of hardened concrete, forming compounds like calcium sulfate and calcium sulfoaluminate which occupy more space than the substances they replace, causing the concrete to expand and disrupt.

01:22Electrophilic Aromatic Substitution: Sulfonation of Benzene
7.2K
Sulfonation of benzene is a reaction wherein benzene is treated with fuming sulfuric acid at room temperature to produce benzenesulfonic acid. Fuming sulfuric acid is a mixture of sulfur trioxide and concentrated sulfuric acid.

Accurate analysis of complex samples often requires advanced preparation techniques to achieve reliable and reproducible results. Samples containing inorganic or organic materials can be challenging to dissolve or decompose effectively. Standard sample preparation methods include acid digestion, fusion, dry ashing, and wet digestion.
Acid digestion with strong acids is commonly used to dissolve inorganic materials that are insoluble (do not dissolve) in water. This method can be useful for...
