Impact of Rexidin SRS mouthwash on the corrosion characteristics of Ni-Cr orthodontic wire submerged in artificial saliva

Zaštita Materijala
Teeth that are well-aligned are viewed as attractive, but some individuals have naturally irregular teeth alignment. To correct this, orthodontists use wires.

Application of Baicalein Solution as a Novel Antioxidant After Bleaching: Analysis of Its Effects on Immediate Color Stability and the Reestablishment of Bond Strength in Bleached Enamel

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the antioxidant capacity of the baicalein solution (BA), as well as its effect when applied for different times to the surface of bleached dental enamel, considering immediate color stability and bond strength. Materials and Methods Bovine enamel/dentin specimens (4 × 4 × 3 mm) were randomly divided into five groups (n ...

Influence of Universal Adhesives With or Without Silane Compared to One‐Step and Two‐Step Silane Agents on Bond Strength to Lithium Disilicate

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the microshear bond strength (μSBS) to lithium disilicate achieved with universal adhesives (with and without silane) compared with one‐step and two‐step silanes, immediately (IM) and after thermocycling (TC). Chemical interaction (CI) was also assessed.

Measurement of Bending Deformation for Small Diameter Orthodontic Wires

, 1979
The stiffness tester and torque meter were found to yield nearly the same measurements of bending deformation for orthodontic wires as small as .007 inch diameter, provided the different bending apparatus are calibrated to each other.

Eccentric Occlusal Loads Remodel the Dentoalveolar and Temporomandibular Biomechanical Unit in Rats

Journal of Oral Rehabilitation, EarlyView.
Eccentric occlusal loads remodel the dentoalveolar and temporomandibular joints in the masticatory biomechanical unit in rats. (A) Bite block as an occlusal rise (OR) on the rat maxillary first molar (green region) is shown. (B) 18F‐NaF Positron emission tomography localised regions of higher metabolic activity (higher uptake in the left condyle ...

Release of nickel and chromium ions from orthodontic wires following the use of teeth whitening mouthwashes

Progress in Orthodontics, 2018
Background Corrosion resistance is an important requirement for orthodontic appliances. Nickel and chromium may be released from orthodontic wires and can cause allergic reactions and cytotoxicity when patients use various mouthwashes to whiten their ...

Applied materials engineering for orthodontic wires

Australasian Orthodontic Journal, 1989
Abstract In Australia, the history of materials engineering for orthodontic wires is generally related to the development of the Begg appliance. Therefore, until recently, it has helped in the search for light resilient forces produced by fine high-tensile stainless steel ...

The Impact of Injury Severity, Sex, and Nociceptor Activity on Post‐Traumatic Temporomandibular Joint Osteoarthritis in Mice

Journal of Oral Rehabilitation, EarlyView.
Repeated TMJ injury in mice demonstrated that greater injury severity and female sex exacerbate post‐traumatic TMJ degeneration. While short‐term nociceptor inhibition reduced pain without affecting degeneration, prolonged inhibition modestly attenuated degeneration, suggesting that persistent post‐traumatic pain contributes to TMJ osteoarthritis ...
