“…The size of ZnO NPs formed by CVD is uniform in the range of 59–61 nm, and the coating on the NiTi archwires have high density and good dispersion ( Gholami et al, 2021 ). Nearly all studies on the modification of clear aligners used coatings synthesized by CVD ( Park et al, 2018 ; Xie et al, 2020 ; Zhang et al, 2020 ; Park et al, 2022 ).…”

“…Materials can be endowed with antibacterial properties by adding functional groups such as quaternary ammonium cation (QAC) ( Makvandi et al, 2018 ) and long alkyl chain (LAC) ( Park et al, 2022 ). Although the detailed mechanism of the antimicrobial action of QACs has not been determined, its antibacterial effect is related to the strong affinity and destructive interaction between the positively charged QACs ions and the negatively charged acidic phospholipid head groups in the microbial membrane.…”

“…Clear aligners were coated with a ladder-like PSQ containing quaternary ammonium cations and long alkyl chains, and the antibacterial ability of the PSQ-coated aligners were investigated in vitro and in vivo . PSQ-coated aligners could inhibit the growth of S. aureus and Pseudomonas aeruginosa ( P. aeruginosa ), and could reduce the dental plaque formation on beagle dogs ( Park et al, 2022 ).…”

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.

“…Hybrid materials with activity aimed at killing microorganisms are often based on quaternary ammonium salts, which show quite high toxicity [ 13 ]. Despite the environmental concerns, new biocompatible organosilicon compounds bearing quaternary ammonium groups were reported as safe for applications in dentistry, e.g., as disinfectants or medications [ 14 , 15 ] and coating materials capable of killing bacteria on contact [ 16 , 17 , 18 ]. Antimicrobial superhydrophobic and superoleophobic coatings containing silane quaternary ammonium salts were also used for silk protection [ 19 ].…”

Hybrid polysiloxanes and polysilsesquioxanes grafted with naturally occurring bioactive phytochemicals: eugenol and linalool, were synthesized and investigated with regard to their structure and properties. The two series of materials, differing in the type of inorganic structure and the content of active groups, were coated onto the surface of glass plates, and their antibiofilm activities against bacteria Aeromonas hydrophila were assessed by luminometry and fluorescence microscopy. Bioactivity was correlated with specific properties of the hybrid coatings (chemical structure, surface free energy and adhesiveness). The functionalized polysilsesquioxanes exhibited the most favorable anti-adhesive effects. Cell adhesion after 6 days of incubation, expressed as RLU/cm2, was significantly reduced (44 and 67 for, respectively, Z-E-100 and Z-L-100, compared to 517 for the control glass carrier). The surface stickiness of polysiloxane films deteriorated their anti-adhesion properties, despite the presence of a large amount of bioactive species.

“…In addition, several groups have paid attention to the addition of silver (Ag) nanoparticle (NP) or quaternary ammonium salt into the substrate in the material fabrication due to their excellent antibacterial property [ 3 , 4 , 8 , 9 ]. However, the biofilm-based Clear Overlay Appliance (COA) fabricated by these strategies (i) is easily cracked and has to be frequently changed, (ii) suffers from strong adhesion which leads to the severe aggregation of bacteria and dust on the surface, and (iii) the leakage of antibacterial agents causes an unavoidable cytotoxicity [ 10 , 11 , 12 ]. Therefore, it is necessary to develop a novel dental retainer with low-cost and no-toxicity or low toxicity for excellently bacterial activity.…”

In the oral microenvironment, bacteria colonies are easily aggregated on the tooth-restoration surface, in the manner of a biofilm, which usually consists of heterogeneous structures containing clusters of a variety of bacteria embedded in an extracellular matrix, leading to serious recurrent caries. In this contribution, zero-dimensional (0D) bismuth (Bi) quantum dots (QDs) synthesized by a facile solvothermal method were directly employed to fabricate a Bi QD/polydimethylsiloxane (PDMS)-modified tooth by simple curing treatment. The result demonstrates that the as-fabricated Bi QD/PDMS-modified tooth at 37 °C for 120 min not only showed significantly improved hydrophobic performance with a water contact angle of 103° and 115° on the tooth root and tooth crown, respectively, compared to that (~20° on the tooth root, and ~5° on the tooth crown) of the pristine tooth, but also exhibited excellent antibacterial activity against S. mutans, superior biocompatibility, and biosafety. In addition, due to the highly photothermal effect of Bi QDs, the antibacterial activity of the as-fabricated Bi QD/PDMS-modified tooth could be further enhanced under illumination, even at a very low power density (12 mW cm−2). Due to the facile fabrication, excellent hydrophobicity, superior antibacterial activity, and biocompatibility and biosafety of the Bi QD/PDMS-modified tooth, it is envisioned that the Bi QD/PDMS-modified tooth with a fascinating self-cleaning and antibacterial performance can pave the way to new designs of versatile multifunctional nanocomposites to prevent secondary caries in the application of dental restoration.
