Peterson BW, Tjakkes GH, Renkema AM, Manton DJ, Ren Y. The oral microbiota and periodontal health in orthodontic patients. Periodontol 2000 2024. [PMID: 39031969 DOI: 10.1111/prd.12594] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 05/14/2024] [Accepted: 06/28/2024] [Indexed: 07/22/2024]
Abstract
The oral microbiota develops within the first 2 years of childhood and becomes distinct from the parents by 4 years-of-age. The oral microbiota plays an important role in the overall health/symbiosis of the individual. Deviations from the state of symbiosis leads to dysbiosis and an increased risk of pathogenicity. Deviations can occur not only from daily life activities but also from orthodontic interventions. Orthodontic appliances are formed from a variety of biomaterials. Once inserted, they serve as a breeding ground for microbial attachment, not only from new surface areas and crevices but also from material physicochemical interactions different than in the symbiotic state. Individuals undergoing orthodontic treatment show, compared with untreated people, qualitative and quantitative differences in activity within the oral microbiota, induced by increased retention of supra- and subgingival microbial plaque throughout the treatment period. These changes are at the root of the main undesirable effects, such as gingivitis, white spot lesions (WSL), and more severe caries lesions. Notably, the oral microbiota profile in the first weeks of orthodontic intervention might be a valuable indicator to predict and identify higher-risk individuals with respect to periodontal health and caries risk within an otherwise healthy population. Antimicrobial coatings have been used to dissuade microbes from adhering to the biomaterial; however, they disrupt the host microbiota, and several bacterial strains have become resistant. Smart biomaterials that can reduce the antimicrobial load preventing microbial adhesion to orthodontic appliances have shown promising results, but their complexity has kept many solutions from reaching the clinic. 3D printing technology provides opportunities for complex chemical syntheses to be performed uniformly, reducing the cost of producing smart biomaterials giving hope that they may reach the clinic in the near future. The purpose of this review is to emphasize the importance of the oral microbiota during orthodontic therapy and to use innovative technologies to better maintain its healthy balance during surgical procedures.

Abstract
Orthodontic appliances significantly influence the microbiological dynamics within the oral cavity, transforming symbiotic relationships into dysbiotic states that can lead to periodontal diseases. This review synthesizes current findings on how orthodontic treatments, particularly fixed and removable appliances, foster niches for bacterial accumulation and complicate oral hygiene maintenance. Advanced culture-independent methods were employed to identify shifts toward anaerobic and pathogenic bacteria, with fixed appliances showing a more pronounced impact compared to clear aligners. The study underscores the importance of meticulous oral hygiene practices and routine dental monitoring to manage these microbial shifts effectively. By highlighting the relationship between appliance type, surface characteristics, treatment duration, and microbial changes, this review aims to enhance dental professionals' understanding of periodontal risks associated with orthodontic appliances and strategies to mitigate these risks. The findings are intended to guide clinicians in optimizing orthodontic care to prevent plaque-associated diseases, ensuring better periodontal health outcomes for patients undergoing orthodontic treatment.

Abstract
Aim To determine the antimicrobial activity of the bacteriocin-producing probiotic strains Streptococcus salivarius K12 and Streptococcus salivarius M18 alone or in combination against caries-associated Streptococcus mutans. Methods Antimicrobial activity of S. salivarius K12 and/or S. salivarius M18 against S. mutans ATCC 25175 growth and biofilm formation on hydroxyapatite (HA) discs was determined in a flow chamber model by recording the colony forming units (CFU/ml) after 48 h of co-cultivation. The biofilm was analyzed by scanning electron microscopy (SEM) and by confocal laser scanning microscopy (CLSM). Additionally, the simultaneous antagonism assay was used to assess the inhibitory effect of S. salivarius K12 and/or S. salivarius M18 against S. mutans ATCC 25175 and 21 clinical isolates of S. mutans. Results Co-cultivation of S. mutans and S. salivarius K12 and/or S. salivarius M18 led to the inhibition of S. mutans viability, thereby, preventing its biofilm formation on HA discs. Furthermore, S. salivarius K12 and S. salivarius M18 exhibited antimicrobial activity against most clinical isolates of S. mutans. Conclusion The in vitro flow chamber system used in this study allows the simulation of time-dependent administration of S. salivarius probiotic strains, either alone or in combination, to investigate the prevention of S. mutans biofilm formation in a standardized model.

Abstract
PURPOSE Bacteria-induced white spot lesions are a common side effect of modern orthodontic treatment. Therefore, there is a need for novel orthodontic bracket materials with antibacterial properties that also resist long-term abrasion. The aim of this study was to investigate the abrasion-stable antibacterial properties of a newly developed, thoroughly silver-infiltrated material for orthodontic bracket application in an in situ experiment. METHODS To generate the novel material, silver was vacuum-infiltrated into a sintered porous tungsten matrix. A tooth brushing simulation machine was used to perform abrasion equal to 2 years of tooth brushing. The material was characterized by energy dispersive X‑ray (EDX) analysis and roughness measurement. To test for antibacterial properties in situ, individual occlusal splints equipped with specimens were worn intraorally by 12 periodontal healthy patients for 48 h. After fluorescence staining, the quantitative biofilm volume and live/dead distribution of the initial biofilm formation were analyzed by confocal laser scanning microscopy (CLSM). RESULTS Silver was infiltrated homogeneously throughout the tungsten matrix. Toothbrush abrasion only slightly reduced the material's thickness similar to conventional stainless steel bracket material and did not alter surface roughness. The new silver-modified material showed significantly reduced biofilm accumulation in situ. The effect was maintained even after abrasion. CONCLUSION A promising, novel silver-infiltrated abrasion-stable material for use as orthodontic brackets, which also exhibit strong antibacterial properties on in situ grown oral biofilms, was developed. The strong antibacterial properties were maintained even after surface abrasion simulated with long-term toothbrushing.

Abstract
BACKGROUND To explore the relationship between changes in salivary cytokine levels and the occurrence of white spot lesions in adolescents receiving clear aligner orthodontic treatment and investigate the predictive value of various factors for lesion occurrence. METHODS We retrospectively analyzed sixthy eight adolescent in the permanent dentition period, who received clear aligner orthodontics in our hospital were randomly divided into two groups according to the occurrence or aggravation of white spot lesions after treatment. The general condition of the oral cavity was analyzed, saliva was collected, and inflammation-related cytokines with varying transcription levels between groups were screened by transcriptome analysis. The expression levels of inflammatory cytokines in the saliva of the patients in the two groups were measured, and the risk factors for white spot lesions were screened by correlation analysis and binary logistic regression analysis. The value of the independent and combined application of risk factors for predicting the occurrence of white spot lesions in adolescent patients after invisible orthodontic treatment was analyzed by receiver operating characteristic (ROC) curve analysis. RESULTS Transcriptome and GO and KEGG pathway analyses showed that there were differences in the transcription levels of inflammatory cytokines such as CXCL1, CXCL2, CXCL8, CCL3, CCL4, IL-1β and IL-2 between groups. The levels of CXCL8, CCL3, CCL4, IL-1β and IL-2 in the saliva of patients with white spot lesions were significantly higher in patients after invisible orthodontic treatment (P < 0.05). Correlation analysis and binary logistic regression analysis showed that elevated levels of CXCL8, IL-1β and IL-2 were independent risk factors for the occurrence of white spot lesions (P < 0.05). CXCL8 had the highest independent predictive value for the occurrence of white spot lesions (AUC = 0.773, P < 0.05), and the combination of IL-1β and IL-2 was also of high value in predicting the occurrence of white spot lesions. CONCLUSION After invisible orthodontic treatment, the oral microenvironment, including inflammatory cytokine levels, in adolescent patients changes; in particular, the levels of inflammatory cytokines such as CXCLs and ILs change. CXCL8 expression is significantly associated with the occurrence of white spot lesions and is an important potential target for the prevention and treatment of white spot lesions in the future.

Am J Orthod Dentofacial Orthop 2022; 162:594-600. [PMID: 37830534 DOI: 10.1016/j.ajodo.2022.06.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2022] [Revised: 06/01/2022] [Accepted: 06/01/2022] [Indexed: 11/01/2022]
Abstract
INTRODUCTION Fixed appliances limit patients' ability to clean their teeth, thus making orthodontic patients highly susceptible to developing white spot lesions (WSLs). Using patient compliance would be one of the simplest methods to prevent WSLs. METHODS A parallel trial design with 34 patients that met the eligibility criteria were randomized to experimental (received Blue M oxygen for health toothpaste) and control (received Colgate Total fluoridated toothpaste) groups. The eligibility criteria were that the patients should be aged 13-30 years, on fixed mechanotherapy, had undergone therapeutic extraction of all first premolars, had completed leveling and aligning, and had satisfactory oral hygiene (assessed using pretreatment and current Simplified Oral Hygiene Index scores). The objectives were to assess the effects of active oxygen-containing toothpaste on Streptococcus mutans (SM) and WSLs in patients undergoing fixed mechanotherapy. The random allocation sequence was generated using the RAND function in Microsoft Excel. The sequence generated was sealed in opaque white envelopes. The investigators and the participants were blinded until allocation. Blinding of the first author (J.A.G.) who dispensed the toothpaste or the participants was not possible. The outcome assessment was blinded by coding the plaque specimens sent for real-time polymerase chain reaction (RT-PCR) to ensure that the final data assessment was blinded. The study setting was the Department of Orthodontics and Dentofacial Orthopedics, Sri Ramachandra Institute of Higher Education and Research (SRIHER) University. The primary outcome was SM counts, which were analyzed using RT-PCR. The secondary outcome was WSL assessment, performed using DIAGNOdent and International Caries Detection and Assessment System (ICDAS) II criteria at baseline and after 4 weeks. The data were subjected to statistical analysis. RESULTS Thirty-four patients were randomized to 17 per group and analyzed. RT-PCR showed lower SM in the experimental group (Ct = 32.25 ± 10.6) than in the control group (Ct = 30.9 ± 10.49). However, this was not statistically significant (P = 0.70). ICDAS scores remained the same from baseline and after 4 weeks for both groups. The DIAGNOdent values were in tandem with the ICDAS scores and showed minimal change for the 2 groups (P >0.05). A strong positive correlation was observed for DIAGNOdent and ICDAS scores (τb >0.30). No harms or adverse effects were observed or reported by the patients during the experimental period. CONCLUSIONS The active oxygen-containing toothpaste showed a greater inhibitory effect on SM than the fluoridated toothpaste. However, this effect was minimal. Both kinds of toothpaste showed negligible effects on WSLs. Thus, active oxygen-containing toothpaste is as effective as fluoridated toothpaste. REGISTRATION The Trial was registered in the Controlled Trials Registry India (CTRI/2021/10/037458). PROTOCOL The full protocol can be obtained from any of the authors via e-mail. FUNDING The project was self-funded.

Abstract
The oral microbiota plays a vital role in the human microbiome and oral health. Imbalances between microbes and their hosts can lead to oral and systemic disorders such as diabetes or cardiovascular disease. The purpose of this review is to investigate the literature evidence of oral microbiota dysbiosis on oral health and discuss current knowledge and emerging mechanisms governing oral polymicrobial synergy and dysbiosis; both have enhanced our understanding of pathogenic mechanisms and aided the design of innovative therapeutic approaches as ORALBIOTICA for oral diseases such as demineralization. PubMed, Web of Science, Google Scholar, Scopus, Cochrane Library, EMBEDDED, Dentistry & Oral Sciences Source via EBSCO, APA PsycINFO, APA PsyArticles, and DRUGS@FDA were searched for publications that matched our topic from January 2017 to 22 April 2022, with an English language constraint using the following Boolean keywords: ("microbio*" and "demineralization*") AND ("oral microbiota" and "demineralization"). Twenty-two studies were included for qualitative analysis. As seen by the studies included in this review, the balance of the microbiota is unstable and influenced by oral hygiene, the presence of orthodontic devices in the oral cavity and poor eating habits that can modify its composition and behavior in both positive and negative ways, increasing the development of demineralization, caries processes, and periodontal disease. Under conditions of dysbiosis, favored by an acidic environment, the reproduction of specific bacterial strains increases, favoring cariogenic ones such as Bifidobacterium dentium, Bifidobacterium longum, and S. mutans, than S. salivarius and A. viscosus, and increasing of Firmicutes strains to the disadvantage of Bacteroidetes. Microbial balance can be restored by using probiotics and prebiotics to manage and treat oral diseases, as evidenced by mouthwashes or dietary modifications that can influence microbiota balance and prevent or slow disease progression.

Abstract
Objectives:
Anchorage preservation is crucial in orthodontic treatment success. Mini-implants make a revolution in this domain. The failure of orthodontic mini-implants due to inflammation and infection is one of the reasons for anchorage loss. The purpose of this study was to evaluate the effect of a novel mini-implant surface modification to improve resistance against microbial contamination and surrounding tissue inflammation.
Material and Methods:
Twenty-four orthodontic mini-implants (Jeil Medical Corporation, Korea) with 1.6 mm diameter and 8 mm length were randomly divided into three groups: Group 1: Control group, Group 2: Nanotubes were made on the surface with anodisation, and Group 3: Zinc Oxide (ZnO) doped into nanotubes, and then doxycycline is added to them. The anti-bacterial efficacy against Porphyromonas gingivalis was evaluated using the disk diffusion method. To analyze data, Kruskal–Wallis, Friedman, and Wilcoxon tests were done. The significance level was set at 0.05.
Results:
No zone of the inhibition was formed in Groups 1 and 2. In Group 3, the mean (SD) diameter of the inhibition zone in the first 5-day to sixth 5-day were 38.7(8.2), 25(4.8), 17.8(5.6), 7.63(5.37), 1.5(2.83), and 0 millimeters, respectively.
Conclusion:
Nanotubes containing doped ZnO and Doxycycline are capable of preventing bacterial growth around the mini implant surfaces for at least up to 30 days. To manage inflammation of surrounding tissues of mini-implants, nanotubes are not effective alone. Therefore, the presence of diffusible materials in addition to nanotubes on the surface of mini-implants is necessary.

Abstract
OBJECTIVES To systematically review existing literature regarding clinical parameters comparing surgical laser and conventional surgery with scalpel for soft tissue adjunctive periodontal procedures in orthodontic patients. METHODS AND MATERIALS MEDLINE, Scopus, Web of Science, The Cochrane Library, LILACS, Bibliografia Brasileira de Odontologia (Brazilian Dental Literature - BBO), Embase, Open Grey, Portal de Periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Coordination for the Improvement of Higher Education Personnel - CAPES), and Google Scholar were searched up to December 2020 without language restriction. Clinical trials comparing clinical parameters from surgical laser and conventional surgery with scalpel for soft tissue adjunctive periodontal procedures in orthodontic patients were selected. Risk of bias (RoB) assessments were performed using the Cochrane RoB2 tool. Narrative syntheses were performed, and the certainty of evidence was determined using the GRADE tool. RESULTS Five randomized clinical trials were included. One study was rated as low RoB, whereas others presented some concerns or high RoB. The studies were highly heterogeneous in relation to the procedure performed, laser protocol, outcomes evaluated, and follow-up periods. In general, regardless of the procedure and laser protocol used, the studies did not show significant differences between laser and scalpel for the outcomes of probing pocket depth, clinical crown length, gingival index, and relapse rate. Pain and bleeding were significantly lower with the use of laser compared with the scalpel. The certainty of evidence ranged from moderate to very low. CONCLUSIONS The existing literature on the subject is scarce and very heterogeneous and has methodological limitations. Based on the available evidence, it is not possible to draw definitive conclusions about the beneficial effect of laser use in orthodontic patients.

Abstract
The purpose of this study was to evaluate changes in short tandem repeat (STR) profile quality before and after fixed orthodontic therapy. Samples of oral epithelial cells were obtained from 28 volunteers who had an indication for orthodontic treatment. The samples were collected before and three months after starting orthodontic treatment with fixed appliances. DNA extraction and integrity were evaluated by electrophoresis, and STR profiles were obtained by polymerase chain reaction amplification and STR typing via capillary electrophoresis. DNA electrophoresis showed a higher proportion (7/28, 25%) of DNA degradation in the samples collected after fixed orthodontic treatment compared to those obtained before starting orthodontic therapy (3/28, 11%), however, changes in DNA were not significant (p=0.289). In concordance all STR profiles showed complete genotyping; however, imbalances in the size of heterozygotes and in the signal were detected in 25% of STR profiles after orthodontic therapy. Moreover, STR instability was demonstrated by an increase in stutter bands detected in 60% of the DNA profiles after treatment and a spurious allele of the D195433 marker was found in one sample after treatment. The STR profiles of samples obtained from the oral cavity with orthodontic appliances should be interpreted with caution. STR instability increases the incidence of artifacts that could compromise the quality of the results of tests performed in forensic DNA laboratories.

METHODS Bacterial biofilms on the surface of 304-Cu SS were characterized by plate counting, 4', 6-diamidino-2-phenylindole (DAPI) staining with aid of sanning electron microscopy (SEM) and 2, 3-bis (2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide inner salt (XTT). In addition, the inhibition zone method was also employed to evaluate the antibacterial properties of 304-Cu SS. Cell Counting Kit-8 (CCK-8) and flow cytometry were used to assess the cytotoxicity and apoptosis rate of 304-Cu SS, respectively. RESULTS 304-4.5Cu SS could effectively inhibit the attachment, formation, activity, and metabolism of bacterial biofilm, possessing the best antibacterial properties exceeding 99.9% of antibacterial rate against S. mutans, S. sanguinis, and their mixture. The diameters of inhibition zones to S. mutans and S. sanguinis on the surface of 304-4.5Cu SS were 21.7 and 14.7 mm, respectively. The results of cell experiments in vitro showed that both 304-2.5Cu SS and 304-4.5Cu SS had no evident cytotoxicity with an identical grade 1. The apoptosis rate exhibited a gradually increased tendency with increase of the Cu content in 304 SS. CONCLUSIONS 304-4.5Cu SS without cytotoxic effect on NIH3T3 cells has obvious antibacterial activity against S. mutans, S. sanguinis and their mixture. CLINICAL SIGNIFICANCE The Cu-bearing stainless steel provides a new solution to be used as oral orthodontic devices for inhibiting oral microflora imbalance and enamel demineralization.

Oral colonization of Candida albicans and Streptococcus mutans in children with or without fixed orthodontic appliances: A pilot study. J Dent Sci 2022; 17:451-458. [PMID: 35028070 PMCID: PMC8739723 DOI: 10.1016/j.jds.2021.07.026] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2021] [Revised: 07/15/2021] [Indexed: 01/31/2023] Open
Abstract
Background/purpose Adolescents undergoing fixed orthodontic therapy have an increased risk of oral diseases due to additional plaque accumulation sites. However, the effect of fixed orthodontics appliances (FOAs) on the colonization of Candida albicans (Ca) and Streptococcus mutans (Sm), two synergistic oral pathogens, is largely unknown and was, therefore, the primary objective of this pilot investigation. Material and methods Sixteen children aged 10–15 years were enrolled, nine in the FOA and seven in the control groups. Saliva and occlusal plaque were collected, and the Ca and Sm levels were quantified with a quantitative real-time polymerase chain reaction (qPCR) assay. Results A trend of higher Ca levels was observed in the saliva and occlusal plaque of the FOA group, while the control group contained higher levels of Sm. Furthermore, for Sm levels, a positive correlation between saliva and occlusal plaque was shown in both the FOA and control groups; in contrast, Ca levels were negatively correlated between these samples only in the FOA group. Between Ca and Sm, a positive correlation was observed in saliva and occlusal plaque in the control group; however, this relationship was disrupted in the FOA group. Conclusion Our preliminary study demonstrated that the presence of FOAs disturbs the colonization of Ca and Sm within the oral cavity. This perturbation might increase orthodontic patients’ risk for Ca- and Sm-related diseases.

Abstract
INTRODUCTION The success of surgery first approach has been defined by the number of advantages offered and is definitively determined by the satisfaction of the patients themselves. The strength of this protocol resides in its philosophy that puts the patient at the center of the whole diagnostic-therapeutic process. The compliance of the patient, its happiness and comfort are the best guarantee of a good final results. While pursuing this philosophy we have wondered whether there was way to increase the comfort of surgery first approach even more and to make it even more appealing for the patients. For these reasons, we have decided to work on a preliminary protocol in order to reduce or even eliminate the use of orthodontic braces and wires during perioperative stages. Materials and Methods: No orthodontic braces or wires are bonded on the teeth before surgery. Intraoperatory intermaxillary fixation (IMF) is carried out with the use of IMF screws which are positioned at the beginning of the operation on the edge between keratinized and nonkeratinized gingiva. Once the osteotomies are performed IMF with IMF screws is carried out on the planned occlusion with the use of surgical splints.Discussion and Conclusions: In selected cases the postsurgical orthodontic treatment can be carried out with the use of clear aligners, completely eliminating the need of braces and wires with an additional level of comfort.

Abstract
OBJECTIVES The aim of this study was to evaluate the microbiological and mechanical properties of glass ionomer cement (GIC) modified by chlorhexidine (CLX) for the purpose of cementing bands to the teeth of orthodontic patients. MATERIALS AND METHODS Ten patients, between the ages of 19 and 33 years, in the initial stage of orthodontic treatment, were randomly designated to two groups using the split-mouth design (n = 10). One group (GICEX) had bands cemented with GIC modified by CLX and a Control group (GIC), evaluated at time intervals before (T0), 3 months (T3), and 6 months (T6) after cementation. Total microbiological counts were performed, and color stability of tooth enamel, salivary pH, and the adhesive remnant index (ARI) were evaluated. STATISTICAL ANALYSIS The Friedman and Dunn's tests, Mann-Whitney, one-way analysis of variance, and Tukey, and paired and non-paired t-tests (p< 0.05) were used. RESULTS In T3, there was evidence of significant reduction in the quantity of colony forming unit (CFU) in GICEX group in comparison with the Control (p = 0.041). In T6, the quantity of CFU was similar to the quantity in T3 and significantly different to control (p = 0.045); Control group demonstrated a similar quantity of CFU between the experimental time intervals (p = 0.066). Salivary pH demonstrated significant difference only between the time intervals T0 and T6 (p = 0.022). The tooth enamel color (p = 0.366) and ARI (p = 0.343) values demonstrated no significant changes. CONCLUSION The incorporation of CLX into GIC demonstrated effective antibacterial action, allowed a good bond of the cement to the enamel, a high rate of survival of the bands, did not change the color of the tooth enamel, and maintained the salivary pH at physiological levels.

Abstract
OBJECTIVE Fixed orthodontic appliances impair oral hygiene increasing the risk of non-cavitated lesions (NCLs) and tooth decay. The aim of this study was to compare the outcomes of fluoride and xylitol varnishes in preventing NCLs during comprehensive orthodontic treatment. MATERIALS AND METHODS The sample comprised 55 volunteers from 15 to 20 years of age under orthodontic treatment that were randomly divided into three groups: Fluoride Group (FG; n=17), Xylitol Group (XG; n=19), and Placebo Group (PG; n=19). The patients in each group received two applications of the following varnishes: DuraphatTM (5% NaF), 20% xylitol, and placebo (no F/Xylitol) in the three groups, respectively. The varnishes were applied in the first appointment (T0) and 3 months later (T1). Clinical examinations were carried out at T0 and 6 months after (T2) using the ICDAS index and the QLF system (fluorescence difference). The intergroup comparisons were performed by ANOVA/Tukey's or Kruskal-Wallis/Dunn's tests (P<0.05). RESULTS There was no significant intergroup difference regarding ICDAS index changes from T0 to T2. Fluoride varnish produced significantly greater increase in fluorescence of NCLs (mean change of -0.65 +0.78 and -0.56 +0.83, for maxilla and mandible, respectively) in comparison to the other groups. The majority of non-cavitated lesions improved in the fluoride and xylitol varnish groups. CONCLUSIONS Fluoride varnish produced significantly greater increase in enamel fluorescence compared to xylitol and placebo varnishes. In short term, both fluoride and xylitol varnishes produced remineralization of NCLs in orthodontic patients. CLINICAL RELEVANCE Non-cavitated lesions can be effectively controlled in high-risk orthodontic patients by means of fluoride varnishes.

Abstract
Aggressive periodontitis during adolescence has a poor prognosis due to rapid alveolar bone resorption. Few studies have investigated long-term follow-up after surgical orthodontic treatment performed in conjunction with that for invasive periodontitis. Here, we report a case of mandibular prognathism accompanied by generalized aggressive periodontitis and crowding. A 31-year-old woman was referred to our department for treatment of masticatory dysfunction due to reverse overjet. The patient exhibited a class III molar relationship, protrusion of the ANB of -6.0°, and severe maxillary crowding. Initial periodontal examination revealed deep periodontal pockets and extensive inflammation. Mandibular prognathism accompanied by generalized aggressive periodontitis and crowding was diagnosed. Therefore, it was necessary to adopt an interdisciplinary approach involving surgical, orthodontic, and periodontal treatment. Prior to commencement of orthodontic treatment, plaque control, scaling, and root planing of all teeth were performed by a periodontist to suppress inflammation and reduce probing depth. During pre-surgical orthodontic treatment, the maxillary first premolars were extracted to reduce crowding of the maxillary incisors. To correct the mandibular prognathism, the mandible was repositioned by sagittal split ramus osteotomy. Proper occlusion of the incisors and maximum intercuspation were achieved by post-surgical orthodontic treatment. After completion of active orthodontic treatment, acceleration of inflammation was observed together with aggravated resorption of the alveolar bone surrounding the molars. However, reduction of probing depth and inflammation were observed after scaling and root planing. The surgical-orthodontic treatment time was 1 year and 11 months, which was followed by a 2-year retention period. There was no tooth loss due to periodontitis, and an overall satisfactory outcome was achieved.

Abstract
Background Orthodontic treatment is widely used to treat malocclusion. However, the influence of treatment on the oral microbiome remains unclear. In this study, we investigated salivary microbial changes in patients undergoing orthodontic treatment. Methods In total, 19 orthodontic patients participated in this study. Saliva samples were collected at the following three timepoints: before (T0) and 3 months (T1) and 6 months (T2) after the placement of orthodontic appliances. High-throughput sequencing was performed based on the 16S rRNA gene V4 region. Results The phyla of Proteobacteria, Bacteroidetes, Firmicutes, Actinobacteria and Fusobacteria were predominant. Observed Species, Chao1 and ACE, which represent α diversity, were significantly decreased at T1 and subsequently increased at T2. In addition, the β diversity at T1 based on the Bray-Curtis distances differed from T0 and T2. The relative abundances of Prevotella, Porphyromonas and Peptostreptococcus were decreased with treatment, whereas those of Capnocytophaga and Neisseria exhibited the opposite results. In total, 385 of 410 operational taxonomic units were shared at T0, T1 and T2. The co-occurrence networks with hub nodes at T1 were the most complex. Conclusion Orthodontic treatment temporarily affected the saliva microbial community. This dynamic alteration in species did not induce deterioration in oral health. Oral hygiene instructions were necessary and should be emphasized during each visit. Further studies with longer observation periods and more participants are required.

Abstract
OBJECTIVE To evaluate the subgingival microbiological changes during the first six months of therapy with clear aligners (CAs) and fixed appliances (FAs). The null hypothesis was that there would be no microbiological differences between the two. SETTING/SAMPLE Two groups of patients to be treated, respectively, with CAs (14 patients; 9 females and 5 males; mean age 21 years ± 0.25) and FAs (13 patients; 8 females and 5 males; mean 14 years ± 0.75) were consecutively recruited. MATERIALS AND METHODS Subgingival microbiological samples were obtained at the right upper central incisor and right first molar at four different time points: before appliance fitting (T0), and at 1 month (T1), 3 months (T3) and 6 months (T6) thereafter. Total bacterial load (TBL) and counts of the bacteria Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Fusobacterium nucleatum, Campylobacter rectus, Treponema denticola and Tannerella forsythia were determined using real-time PCR. RESULTS Total bacterial load did not vary in the CA group, while a significant increase was detected after 3 and 6 months of treatment in the FA group. Unlike red complex species, C rectus and F nucleatum were often detected: levels remained stable in the CA group but increased progressively in the FA group. CONCLUSION The type of orthodontic appliance influences the subgingival microbiota. TBL increased in the FA group but not in the CA group, although the levels of the individual periodontal pathogenic bacteria species did not significantly increase during the observation period.

Abstract
AIM This study aims to review the available evidence on the efficacy of behaviour change techniques to improve compliance in young orthodontic patients and to compare these with conventional oral hygiene instructions. METHODS The review was conducted according to the PRISMA statement. PICO method was used to define eligibility criteria. Two independent reviewers performed the research, examined electronic databases (MEDLINE, Scopus and CENTRAL) and manually checked relevant journals. Only RCTs with more than 10 participants and 3 months follow-up were included. Data extraction and their qualitative analysis were performed for included studies. RESULTS Search strategy identified 320 articles. After screening for titles, abstracts and full texts, 10 articles were then selected for qualitative analysis. High methodological heterogeneity was present among studies and therefore no meta-analysis was performed. Low risk of bias was detected for one study only. The most common intervention was "mobile phone communication," which was investigated in five studies. Motivational interviewing, repeated reinforcements and visual-aided approach were also examined. CONCLUSION The interest in remote control of patients compliance appears to be fruitful, nonetheless there is no consensus as to a unique treatment protocol. Every other treatment looks beneficial but higher methodological homogeneity should be sought for in future investigations.

Abstract
Relevance. Skeletal malocclusion stands at the head of all oral diseases and is encountered in 32-35% of children and adolescents in Russia [7;12;15]. The number of malocclusions has increase due to various reasons, one of which is early extraction of deciduous carious teeth resulting in impaired vertical dimension and occlusion of teeth [1;14]. Diagnosis with due regard to caries resistance degree and planning of respective operative and orthodontic treatment are indispensable in children with skeletal malocclusion. Purpose – to increase effectiveness of functional treatment of malocclusion in children with various degree of caries resistance.Materials and methods. There were examined 108 patients aged between 6 and 16 with Class I malocclusion according to Angle, abnormal arch-to-arch relationship and tooth position and various degree of caries resistance. 4 groups were formed: high, sufficient mean, decreased mean and low caries resistance of dental enamel. Intensity of carious process was detected in all patients before and after orthodontic treatment. The effectiveness of reminerlization administered by removable orthodontic appliances was evaluated by electrometrical testing of hard dental tissue. Surface EMG was used to assess normalization of tone of maxillofacial muscles in children by average amplitude of biopotentials of superficial masseter and temporalis muscles.Results. Сhanges in caries intensity in children after treatment with removable orthodontic aligners indicate the necessity for remineralization of hard dental tissues during orthodontic treatment and it is confirmed by decrease of electroconductivity of enamel in children with sufficient mean, decreased mean and low degree of dental enamel caries resistance. Increase of biopotential mean amplitude during «total mastication» for masseter and temporal muscles confirms effectiveness of preformed elastic positioner along with myodynamic exercises.Conclusions. The conducted study proves the necessity of comprehensive approach with procedures increasing the degree of caries resistance of hard dental tissues during orthodontic treatment of skeletal malocclusion in children.
