Summary
Ultrasonic scaling of dental implants releases titanium particles and damages the implant surface. Caution is advised when using ultrasonic scalers on sandblasted, large grit, acid-etched (SLA) surfaces to avoid peri-implant breakdown.
Area of Science:
- Biomaterials Science
- Dental Implantology
- Materials Science
Background:
- Titanium particles are a potential concern in peri-implant breakdown.
- Ultrasonic scalers are commonly used for debridement of peri-implant lesions.
Purpose of the Study:
- To investigate titanium particle generation during ultrasonic scaling of dental implants.
- To assess damage to the implant surface after ultrasonic scaling.
Main Methods:
- Sandblasted, large grit, acid-etched (SLA) coated implants were scaled using ultrasonic tips (stainless steel, titanium, PEEK).
- Implants were subjected to 30 scaling motions under 25g pressure.
- Coolant water was analyzed for metallic particles, and implant surfaces were evaluated for damage.
Main Results:
- Metallic particles were detected in coolant water when implants were scaled.
- Damage to the SLA coating was observed on all scaled implants.
- Even without direct tip contact, particles were detected, suggesting potential contamination.
Conclusions:
- Ultrasonic scaling generates titanium particles and damages the SLA coating of dental implants.
- Careful use of ultrasonic scalers is recommended for peri-implant conditions.
- Avoid direct contact with the SLA surface during ultrasonic scaling to minimize implant damage.

Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes. Two different solutions can differ in their hydronium or hydroxide ion concentrations by a million, billion, or even trillion times. A common means of...

Dalton was only partially correct about the particles that make up matter. All matter is composed of atoms, and atoms are composed of three smaller subatomic particles: protons, neutrons, and electrons. These three particles account for the mass and the charge of an atom.

02:10The Nucleosome Core Particle
14.5K
Nucleosomes are the DNA-histone complex, where the DNA strand is wound around the histone core. The histone core is an octamer containing two copies of H2A, H2B, H3, and H4 histone proteins.
The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...

In designing and analyzing filters, resonant circuits, or circuit analysis at large, working with standard element values like 1 ohm, 1 henry, or 1 farad can be convenient before scaling these values to more realistic figures. This approach is widely utilized by not employing realistic element values in numerous examples and problems; it simplifies mastering circuit analysis through convenient component values. The complexity of calculations is thereby reduced, with the understanding that...

7.6K
Any physical property that depends consistently and reproducibly on temperature can be used as the basis of a thermometer. For example, volume increases with temperature for most substances. This property is the basis for the common alcohol thermometer and the original mercury thermometers. Other properties used to measure temperature include electrical resistance, color, and the emission of infrared radiation.
As many physical properties depend on temperature, the variety of thermometers is...
