“…Shah et al used this method to apply photocatalytic TiO 2 to stainless steel orthodontic brackets in order to assess the antiadherent and antibacterial properties of such compounds against Lactobacillus acidophilus. Photocatalytic TiO 2 demonstrated antibacterial and antiadherent properties; therefore, these authors also recommended it as a surface modification material to prevent developing dental plaque during active orthodontic treatment [70]. Ozeki et al [71] coated NiTi alloy plates with hydroxyapatite, alumina, and titanium using this method to alleviate the effects of nickel allergy from NiTi alloy implants.…”

Coating and Surface Treatments on Orthodontic Metallic Materials

Metallic biomaterials have been extensively used in orthodontics throughout history. Gold, stainless steel, cobalt-chromium alloys, titanium and its alloys, among other metallic biomaterials, have been part of the orthodontic armamentarium since the twentieth century. Metals and alloys possess outstanding properties and offer numerous possibilities for the fabrication of orthodontic devices such as brackets, wires, bands, ligatures, among others. However, these materials have drawbacks that can present problems for the orthodontist. Poor friction control, allergic reactions, and metal ionic release are some of the most common disadvantages found when using metallic alloys for manufacturing orthodontic appliances. In order to overcome such weaknesses, research has been conducted aiming at different approaches, such as coatings and surface treatments, which have been developed to render these materials more suitable for orthodontic applications. The purpose of this paper is to provide an overview of the coating and surface treatment methods performed on metallic biomaterials used in orthodontics.

“…It has also been demonstrated that Listerine and Corsodyl mouth rinses inhibited biofilm formation on orthodontic brackets. 6 Shah et al 7 reported that stainless steel orthodontic brackets modified with a photocatalytic titanium oxide (TiO 2 ) coating resulted in reduced bacterial adherence and less biofilm accumulation. The prevention of biofilm formation has been studied extensively; however, according to recent studies, the prevalence of WSLs remains high.…”

Objective: To compare the esthetic improvements of white-spot lesions (WSLs) treated by fluoride, casein phosphopeptide amorphous calcium phosphate (CPP-ACP), or resin infiltration. Materials and Methods: WSLs were created on human enamel and randomly assigned to four groups: NaF (500 ppm), CPP-ACP, resin infiltration (Icon), or distilled deionized water (DDW; control group). The color change (DE) of each specimen was measured with a Crystaleye spectrophotometer, and fluorescence loss (DQ) was measured by quantitative light-induced fluorescence (QLF), at different time points after treatment: baseline (0 weeks), 2 weeks, 4 weeks, and 6 weeks. Results: The DE and DQ baseline values for the four groups before the treatments did not differ significantly. Icon treatment improved the WSL color significantly and gave the lowest DE (2.9 6 1.2 on average) compared with other treatments (P , .01). The Icon treatment also resulted in a significant change in the DQ of WSLs compared with baseline (P , .01). In the NaF and CPP-ACP treatment groups, DQ showed significant recovery compared with the baseline values only after 4 weeks after treatment (P , .05). Conclusions: Resin infiltration is more effective than NaF or CPP-ACP in providing esthetic improvement of WSLs. (Angle Orthod. 2014;84:343-349.)

“…Shah et al 7) modified the surface of steel and TiO2 orthodontic brackets by using UV radiation treatment, and these brackets had a bactericidal effect on Lactobacillus acidophilus. However, the absorption band of TiO 2 is limited within the UV region to a wavelength of less than 387 nm, and it can only utilize UV light, which constitutes only 5% of sunlight.…”

A bracket coated with a nitrogen-doped (N-doped) TiO 2-x N y thin film was prepared using the RF magnetron sputtering method. The physicochemical properties of the thin film were measured using X-ray diffraction and energy-dispersive X-ray spectrometry, while the antimicrobial activity of the bracket against common oral pathogenic microbes was assessed on the basis of colony counts. The rate of antimicrobial activity of the bracket coated with nano-TiO 2-x N y thin film against Streptococcus mutans, Lactobacillus acidophilus, Actinomyces viscous, and Candida albicans was 95.19%, 91.00%, 69.44%, and 98.86%, respectively. Scanning electron microscopy showed that fewer microbes adhered to the surface of this newly designed bracket than to the surface of the normal edgewise bracket. The brackets coated with the N-doped TiO 2-x N y thin film showed high antimicrobial and bacterial adhesive properties against normal oral pathogenic bacterial through visible light, which is effective in prevention of enamel demineralization and gingivitis in orthodontic patients.
