Summary
A new organic-free implant-paste effectively cleans oral biofilm from titanium dental implants. This novel paste protects implant surfaces from abrasion and organic contamination, unlike conventional toothpastes.
Area of Science:
- Biomaterials Science
- Dental Materials
- Surface Chemistry
Background:
- Maintaining peri-implant health requires effective oral hygiene and regular maintenance.
- Standard prophylaxis products and toothpastes can damage titanium implant surfaces due to organic components and silica microparticles.
- Abrasion and contamination of implant surfaces pose risks to long-term peri-implant health.
Purpose of the Study:
- To develop an organic-free implant-paste for cleaning oral biofilm on titanium dental implants.
- To evaluate the efficacy of the novel implant-paste in removing contaminants and protecting implant surfaces.
- To compare the performance of the implant-paste with commercial toothpastes and prophylaxis brushing alone.
Main Methods:
- Development of an implant-paste using two-dimensional nanocrystalline magnesium phosphate gel and hydrated silica nanoparticles (20-30% w/w).
- Characterization of surface chemistry, morphology, and bacterial load on contaminated titanium (Ti) disks using X-ray photoelectron spectroscopy (XPS), scanning electron microscopy, and fluorescence spectroscopy.
- Comparative analysis of decontamination efficacy using the novel implant-paste, commercial toothpastes, and rotary prophylaxis brush.
Main Results:
- The novel implant-paste effectively removed oral biofilm and significantly reduced carbon contamination on Ti surfaces (from 73% to 20%) compared to commercial toothpastes (to 41%).
- Bacterial load was significantly reduced by the implant-paste to 2 × 10^3 /µm², outperforming rotary prophylaxis brush alone.
- XPS analysis confirmed that the implant-paste protected the Ti metal surface from abrasion and removed organic contaminants, unlike commercial toothpastes.
Conclusions:
- The developed organic-free implant-paste is a promising and efficient approach for decontaminating titanium dental implants.
- This novel paste offers superior protection against surface abrasion and organic contamination compared to conventional toothpastes.
- The findings support the use of this implant-paste for improved peri-implant health maintenance.

00:49Gravimetry: Inorganic And Organic Precipitating Agents
7.1K
In gravimetry, the precipitant is chosen carefully to obtain a pure solid that can be easily filtered. Common inorganic precipitants can be used to determine several cations and anions. In some cases, the formation of the same precipitate can be used to determine the cation and the anion. For example, the reaction of barium and chromate ions to give barium chromate is used to determine both barium and chromate. However, precipitates such as hydroxides, oxalates, and metal ammonium phosphates...

536
Nitrogen is an essential element in biological systems, forming a crucial component of proteins, nucleic acids, and other cellular constituents. Many bacteria and archaea acquire nitrogen in the form of nitrate (NO₃⁻) or ammonia (NH₃), which are then assimilated into biomolecules through specific enzymatic pathways.Assimilatory Nitrate ReductionWhen nitrate enters the cell, it undergoes a two-step reduction process known as assimilatory nitrate reduction. Initially, the enzyme...

Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.

00:56Extraction: Advanced Methods
1.2K
Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

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...

554
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...
