Assessment of coated orthodontic miniscrews with chlorhexidine hexametaphosphate antimicrobial nanoparticles: A randomized clinical trial.

Background: Using miniscrews to control anchorage made the application of force for various orthodontic treatment approaches easier and increased their effectiveness. Some problems may occur during the use of miniscrews, such as peri‑implant mucositis, mobility, postoperative pain, and failure. This study compared the success rate of miniscrews coated with chlorhexidine hexametaphosphate antimicrobial nanoparticles with that of uncoated miniscrews.

A Novel 3-Dimensional Printed Nanoceramic Hybrid Resin Fixed Lingual Retainer: Characterization and Mechanical Tests.

An innovative retention protocol was developed to create a new 3D-printed fixed retainer employing SprintRay OnX nanoceramic hybrid resin. The feasibility and usability of the retainer were subsequently evaluated. Identification and characterization of SprintRay OnX was done using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy with energy dispersive X-ray (SEM-EDX), field emission scanning electron microscope (FE-SEM), X-ray diffraction (XRD), and flexural strength.

Tribology of Coated 316L SS by Various Nanoparticles.

Background: Nanocoating of biomedical materials may be considered the most essential developing field recently, primarily directed at improving their tribological behaviors that enhance their performance and durability. In orthodontics, as in many medical fields, friction reduction (by nanocoatings) among different orthodontic components is considered a substantial milestone in the development of biomedical technology that reduces orthodontic treatment time. The objective of the current research was to explore the tribological behavior, namely, friction of nanocoated thin layer by tantalum (Ta), niobium (Nb), and vanadium (V) manufactured using plasma sputtering at 1, 2, and 3 hours on substrates made of 316L stainless steel (SS), which is thought to be one of the most popular alloys for stainless steel orthodontic archwires.

Clinical management and infection control protocols during the COVID-19 pandemic: An online survey.

Background: SARS-CoV-2 (COVID-19) is considered a highly infectious and life threatening disease.

Objective: The present paper aims to evaluate various aspects of preventive measures and clinical management of the scheduled visits for orthodontic patients to the dental clinics during the outbreak of COVID-19, and to assess how orthodontists dealt with this challenge.

Methods: Orthodontists in private and public clinics were invited to fill a questionnaire that addressed infection control protocols and concerns about clinical management of patients in the clinics during the pandemic.

Surface Characterization of Stainless Steel 316L Coated with Various Nanoparticle Types.

Background: Material tribology has widely expanded in scope and depth and is extended from the mechanical field to the biomedical field. The present study aimed to characterize the nanocoating of highly pure (99.9%) niobium (Nb), tantalum (Ta), and vanadium (V) deposited on 316L stainless steel (SS) substrates which considered the most widely used alloys in the manufacturing of SS orthodontic components.

The effect of COVID-19 on emergencies and pain among orthodontic patients attending a teaching hospital.

This study aimed to evaluate the effect of the COVID-19 outbreak on emergencies and pain among orthodontic patients attending a teaching hospital. The study was conducted among orthodontic patients receiving active orthodontic treatment or in a retention period at the College of Dentistry, University of Baghdad, Iraq. Their participation was voluntary, and they filled out an Arabic-translated questionnaire.

Do orthodontists aim to decrease the duration of fixed appliance treatment?

Objectives: The aim of the present study was to investigate the trends in the use of fixed appliance and accelerated orthodontics to decrease the treatment duration. Further, this study aimed to assess the effect of demographic factors on the participant's choice of treatment modality.

Methods: This was a cross-sectional study in the form of questionnaire-based online survey especially designed and distributed to 265 orthodontists via email.

The efficacy of polyether-ether-ketone wire as a retainer following orthodontic treatment.

Objectives: To investigate the efficacy of polyether-ether-ketone (PEEK) wire as a fixed orthodontic retainer, by comparing its performance to other retainer wires and optimizing its adhesion to composite bonding materials.

Materials And Methods: Retainer wires of 15 mm segments were used, PEEK wires were prepared in cylindrical form with 0.8 mm diameter, and had two surface treatments namely air-abrasion and conditioning with adhesive system.

Retention Protocols and Factors Affecting Retainer Choice among Iraqi Orthodontists.

Background: To identify the most common retention protocols practiced by Iraqi orthodontists using a specially designed e-survey. Furthermore, this study aimed to assess the effect of sociodemographic factors on the participant's choice.

Methods: Two hundred and twenty-five questionnaires with 23 multiple choice questions were sent to members of the Iraqi Orthodontic Society.
