“…A lysozyme coating was proposed again in 2020 [ 122 ], with the aim to improve the corrosion resistance of new orthodontic composite arch wires (CAWs). The CAWs are made of a nickel and titanium alloy and stainless steel produced by laser welding, with copper serving as the interlayer.…”

Lysozyme is a ~14 kDa protein present in many mucosal secretions (tears, saliva, and mucus) and tissues of animals and plants, and plays an important role in the innate immunity, providing protection against bacteria, viruses, and fungi. Three main different types of lysozymes are known: the c-type (chicken or conventional type), the g-type (goose type), and the i-type (invertebrate type). It has long been the subject of several applications due to its antimicrobial properties. The problem of antibiotic resistance has stimulated the search for new molecules or new applications of known compounds. The use of lysozyme as an alternative antibiotic is the subject of this review, which covers the results published over the past two decades. This review is focused on the applications of lysozyme in medicine, (the treatment of infectious diseases, wound healing, and anti-biofilm), veterinary, feed, food preservation, and crop protection. It is available from a wide range of sources, in addition to the well-known chicken egg white, and its synergism with other compounds, endowed with antimicrobial activity, are also summarized. An overview of the modified lysozyme applications is provided in the form of tables.

“…Lysozyme selectively breaks down the cell wall of microorganisms without destroying other tissues, and was used for antibacterial modification of archwires. The 40 g/L lysozyme coating on the CAWs had the strongest inhibitory effect on S. aureus ( He et al, 2020 ).…”

“…During recent years, increasing attention has been paid to the modification of orthodontic brackets, archwires and aligners via surface coatings. Materials such as metals oxides, metal element ( Ghasemi et al, 2017 ), organic compounds ( Park et al, 2018 ) and others ( Dai et al, 2022 ) have been used to form such antibacterial coatings, which can lower the dependence on oral hygiene maintenance, decrease the roughness of appliance surfaces (and the resultant bacterial adhesion), and increase the biocompatibility of orthodontic appliances ( Liu J M et al, 2017 ; Hammad et al, 2020 ; He et al, 2020 ).…”

In the process of orthodontic treatment, the presence of orthodontic appliances makes it difficult to clean tooth surfaces. This can lead to an increased level of bacterial colonization, resulting in enamel demineralization and periodontal diseases. Considering the large surface area that orthodontic appliances usually have and that they can be in direct contact with bacteria throughout the treatment, modifications in the form of coatings on the surface of orthodontic appliances can be an effective and practical approach to reducing bacterial proliferation and preventing relevant adverse effects. In this mini-review, we discuss various antibacterial coatings which have been applied onto orthodontic appliances in recent 5 years, as well as their antibacterial mechanisms and methods for the preparation of these coatings. From this mini-review, both orthodontists and researchers can get the latest findings in the field of antibacterial coatings onto orthodontic appliances, which is helpful for the decision-making in clinical practice and research activities.

“…In the literature, there are many studies on the electrochemical corrosion of archwires used in orthodontic treatment [ 22 , 23 , 24 ]. However, there are not enough studies on the electrochemical corrosion of the retainer wires used as fixed appliances in retentions that are intended to remain in the mouth longer than the applied orthodontic treatment period, or even for a lifetime.…”

(i) Objective: The present study aimed to compare the electrochemical corrosion resistance of six different types of fixed lingual retainer wires used as fixed retention appliances in an in vitro study. (ii) Methods: In the study, two different Ringer solutions, with pH 7 and pH 3.5, were used. Six groups were formed with five retainer wires in each group. In addition, 3-braided stainless steel, 6-braided stainless steel, Titanium Grade 1, Titanium Grade 5, Gold, and Dead Soft retainer wires were used. The corrosion current density (icorr), corrosion rate (CR), and polarization resistance (Rp) were determined from the Tafel polarization curves. (iii) Results: The corrosion current density of the Gold retainer group was statistically higher than the other retainer groups in both solutions (p < 0.05). The corrosion rate of the Dead Soft retainer group was statistically higher than the other retainer groups in both solutions (p < 0.05). The polarization resistance of the Titanium Grade 5 retainer group was statistically higher than the other retainer groups in both solutions (p < 0.05). As a result of Scanning Electron Microscope (SEM) images, pitting corrosion was not observed in the Titanium Grade 1, Titanium Grade 5 and Gold retainer groups, while pitting corrosion was observed in the other groups. (iv) Conclusion: From a corrosion perspective, although the study needs to be evaluated in vivo, the Titanium Grade 5 retainer group included is in this in vitro study may be more suitable for clinical use due to its high electrochemical corrosion resistance and the lack of pitting corrosion observed in the SEM images.
