“…The Dd score in the RMD group showed that the level of demineralization was lower than that in the RMGIC group, although the results of EDI and Dd scores was not sufficient to diagnose demineralization on both groups after 3 months. Previous studies have found that various periodontal indices increased after 3 months of treatment, among which the increase in plaque index was the most obvious ( Kozak, Lasota & Chałas, 2021 ). In our study, compared to RMGIC, plaque accumulation was significantly inhibited by RMD, while no significant difference was observed on gingival index.…”

Objective To explore the influence of resin modified glass ionomer cement (RMGIC) adhesives containing protein-repellent and quaternary ammonium salt agents on supragingival microbiome, enamel and gingival health around brackets. Materials and Methods Ten patients (21.4 ± 3.5 years) about to receive fixed orthodontics were enrolled in this study. Unilateral upper teeth bonded with RMGIC incorporating 2-Methacryloyloxyethyl phosphorylcholine (MPC) and Dimethylaminohexadecyl methacrylate (DMAHDM) were regarded as experimental group (RMD), while contralateral upper teeth bonded with RMGIC were control group (RMGIC), using a split-mouth design. Supragingival plaque was collected from both groups before treatment (T0), and at 1 month (T1) and 3 months (T2) of treatment. High-throughput sequencing was performed targeting v3–v4 of 16S rRNA gene. Streptococcus mutans and Fusobacterium nucleatum quantification was done by qPCR analysis. Bracket failures, enamel decalcification index (EDI), DIAGNODent scores (Dd), plaque index (PI) and gingival index (GI) were monitored at indicated time points. Results Within 3 months, alpha and beta diversity of supragingival plaque had no difference between RMGIC and RMD groups. From T0 to T2, the relative abundance of Streptococcus depleted in RMD but remained steady in RMGIC group. Streptococcus, Prevotella, and Fusobacterium became depleted in RMD, Haemophilus and Capnocytophaga became depleted in RMGIC group but Prevotella enriched. Quantification of Fusbacterium nucleatum and Streptococcus mutans showed significant difference between RMGIC and RMD groups at T2. Teeth bonded with RMD had significant lower plaque index (PI) and DIAGNODent (Dd) score at T2, compared with teeth bonded with RMGIC (p < 0.05). No difference in bracket failure rate was examined between both groups (p > 0.05). Conclusion By incorporating MPC and DMAHDM into RMGIC, the material could affect the supragingival microbial composition, inhibit the progress of plaque accumulation as well as the key pathogens S. mutans and F. nucleatum in the early stage of orthodontic treatment.

“…There are numerous publications in the literature on the effect of acrylic restorations on the adult population. Kozak et al studied the effect of fixed orthodontic appliances on the distribution of dental biofilm [ 18 ]. However, few studies in this area concern removable orthodontic appliances used by the youngest patients [ 19 , 20 , 21 ].…”

The purpose of this study was to analyze the effect of orthodontic treatment with removable appliances on the growth of Candida spp. in children undergoing orthodontic treatment. The study included 60 patients of equal numbers as to gender from the orthodontics department of the Pomeranian Medical University in Szczecin, Poland. All patients were aged 6–12 years and were qualified for orthodontic treatment with removable appliances. The following examinations were performed on the day of treatment initiation (T1) and 6 months after the start of treatment (T2); a collection of oral swabs for culture on Sabouraud’s medium and the identification of fungal colonies using the VITEK®2 YST. At T1, 42 (70%) subjects, were free of Candida, while after 6 months of treatment, the number decreased to 25 (41.67%). Two types of fungi, C. albicans and C. parapsilosis, predominated in the test performed at T1. The study at T2 showed that C. albicans most frequently colonized the oral cavity in 23 children (38.33%). Three new strains C. dubliniensis, C. kefyr, and C. krusei were identified at T2. Statistical analysis showed a significant correlation between the culture results and the age of the patient at T2. Patients older than 9 years had significantly more positive tests. Orthodontic treatment with removable appliances contributes to increased oral colonization by Candida spp.

“…Therefore, the oral cavity should be considered as a possible source of toxigenic Staphylococcus aureus strains, and thus a potential risk of cross-infection and dissemination to other sites in the body [8] . It is important to emphasize that some fixed components used in orthodontics (molar tubes, ceramic brackets, and elastomeric ligatures) were found to show high risks of causing periodontal disease [9] , because orthodontic appliances seem to be associated with a qualitative increase in the subgingival microbiota [10] and also with a frequent increase in the amount of supragingival plaque in the vestibular region of the teeth [11] .…”

Introduction: Staphylococcus aureus is a pathogen present worldwide that produces a large number of toxic molecules, has a 47.5% mortality rate in patients infected with methicillin-resistant Staphylococcus aureus (MRSA), but its prevalence and its contribution to infections in the oral cavity and in the orthodontic area have not been thoroughly investigated. Objective: To analyze the current literature on the presence of Staphylococcus aureus in relation to orthodontics, as well as its prevalence, virulence, biofilm and treatment. Methodology: An electronic search was carried out in the databases PubMed, Google scholar and SCOPUS, compiling articles on Staphylococcus aureus published in the last 5 years; the following keywords were used for the search: "Staphylococcus aureus", "prevalence", "virulence", "biofilm", "treatment", "systemic", "oral", "dental", "orthodontics", among others. Results: A prevalence of Staphylococcus aureus of 90.9% was found on the surface of removable orthodontic appliances. The common virulence factor presents in systemic, oral cavity and proposed orthodontic-related infections is enterotoxins. Adhesion and biofilm formation on the arch wires can be a source of Staphylococcus aureus colonization. The use of 0.2% chlorhexidine rinse is recommended before performing any treatment in oral cavity. Conclusions: It is of utmost importance to inform patients undergoing orthodontic treatment of the risks that can occur if daily removal of the oral micro biota and cleaning of removable appliances before placing them in the mouth is not carried out.
