Abstract
OBJECTIVE This study aimed to compare the pain intensity and impacts on oral health-related quality of life (OHRQoL) between orthodontic patients treated with clear aligners (CAs) and fixed appliances (FAs). METHODS A systematic search was conducted up to December 2022 using PubMed, Web of Science, Cochrane Central Register of Controlled Trials, and Embase. Randomized controlled trials (RCTs) and prospective non-randomized controlled trials (non-RCTs) comparing pain intensity or OHRQoL between patients treated with CAs and FAs were included. The risk of bias (RoB) of individual studies was evaluated using the Cochrane RoB tool 2.0 and ROBINS-I tool for RCTs and non-RCTs, respectively. Further, meta-analyses were separately conducted for each included study using the total oral health impact profile (OHIP)-14 and visual analog scale (VAS) scores to evaluate OHRQoL and pain intensity, respectively. RESULTS Overall, 12 studies (5 RCTs and 7 non-RCTs) were included in the study. Subgroup analyses conducted according to the total OHIP-14 scores revealed that patients treated with CAs had higher OHRQoL at 1 week, 1 month, and 6 months of the treatment. Meanwhile, subgroup analyses conducted according to the VAS scores revealed that pain levels were lower in the CA group only at 3 and 4 days of the treatment. CONCLUSIONS Patients treated with clear aligners had higher OHRQoL than those treated with fixed appliances during orthodontic treatment. However, OHRQoL appeared to be similar between the two groups at the end of the treatment. Moreover, patients treated with clear aligners experienced lesser pain than those treated with fixed appliances on the third and fourth day after the initial treatment. The difference in pain intensity between the two treatment modalities was not noted at other time points.

Abstract
OBJECTIVES This study aimed to design and implement a mobile phone application (app) aiming to enhance the cooperation and oral hygiene of orthodontic patients. METHODS An orthodontic app named "Labkhand" was designed by a team of orthodontists and programmers according to the needs and scheduled interventions for patients. The aim of this app was to obviate the orthodontic needs of patients by providing educational content in the form of texts and videos, oral hygiene reminders, appointment reminders, and nutrition reminders. It also enabled instant messaging and chatting between patients and dental personnel. In this study, 61 patients were monitored during their orthodontic treatment procedure. All patients were evaluated using a questionnaire with 7 questions before and after a 6-month treatment period. A total of 31 patients were instructed to use the app, while the other 30 patients received treatment without the app. The collected data were analyzed using paired t‑test and analysis of covariance (ANCOVA) test. RESULTS While the control group's questionnaire score remained almost the same (P > 0.05), the mean questionnaire score of patients in the intervention group significantly increased after using the app compared to the baseline scores acquired before using the app (P < 0.001). The greatest improvement was noted in topics related to "reminding of appointments", "general information about orthodontic treatment", and "oral hygiene maintenance and instructions". "Quality of services" and "patient-orthodontist communication" showed the least improvement in patient satisfaction. CONCLUSIONS The Labkhand orthodontic app has multiple functions and can obviate the needs of orthodontic patients easily and at a low cost.

Abstract
BACKGROUND Many orthodontic patients request dental bleaching during orthodontic treatment to achieve a faster aesthetic resolution, however, no attention has been paid to the inflammatory processes that can occur when both therapies are indicated together. So, this clinical trial evaluated the inflammatory parameters and color alterations associated with dental bleaching in patients wearing a fixed orthodontic appliance. METHODS Thirty individuals aged between 18 and 40 years were equally and randomly allocated into three groups: FOA (fixed orthodontic appliance), BLE (dental bleaching), and FOA + BLE (fixed orthodontic appliance + dental bleaching). The orthodontic appliances and the bleaching procedures were performed in the maxillary premolars and molars. For dental bleaching a 35% hydrogen peroxide was used. The gingival crevicular fluid (GCF) and nitric oxide (NO-) levels were evaluated at different time-points. Color evaluation was performed using an Easyshade spectrophotometer at baseline (FOA, FOA + BLE, BLE), one month after (FOA + BLE) and 21 days after appliance removing (FOA + BLE and FOA groups), in each tooth bleached. The ANOVA and Tukey's tests, with a significance level of 5%, were used for statistical analysis. RESULTS The GCF volume in the FOA + BLE and FOA groups significantly increased at the time points evaluated (p < 0.001); however, this did not occur in the BLE group (p > 0.05). On the other hand, NO- levels significantly decreased during dental bleaching with or without fixed orthodontic appliances (FOA + BLE and BLE groups; p < 0.05), while no significant changes were observed in the FOA group (p > 0.05). Significant changes in color were observed in the FOA + BLE and BLE groups compared to in the FOA group (p < 0.01). However, the presence of fixed orthodontic appliance (FOA + BLE) negatively affected the bleaching efficacy compared to BLE group (p < 0.01). CONCLUSIONS Dental bleaching did not increase the inflammatory parameters in patients wearing fixed orthodontic appliance. However, in the presence of orthodontic appliances, the bleaching efficacy was lower than that of bleaching teeth without orthodontic appliances. TRIAL REGISTRATION RBR-3sqsh8 (first trial registration: 09/07/2018).

Abstract
OBJECTIVES The objective of this work was to evaluate the impact of fixed orthodontic appliances on oxidative stress (OS) and genotoxicity from oral epithelial cells. MATERIALS AND METHODS Samples of oral epithelial cells were obtained from fifty-one healthy voluntary subjects who had an indication for orthodontic treatment. The samples were obtained before treatment and after 6 and 9 months of treatment. OS was evaluated by quantitating 8-hydroxy-2'deoxyguanosine (8-OHdG) and by performing relative gene expression with antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT). DNA degradation and instability were evaluated by multiplex polymerase chain reaction (PCR) and fragment analysis for human identification. RESULTS The quantitation results showed that 8-OHdG increased during treatment, although this increase was not statistically significant. SOD increased by 2.5- and 2.6-fold after 6 and 9 months of treatment, respectively. CAT increased by threefold after 6 months of treatment, while after 9 months of treatment, the expression level decreased to a level similar to that before treatment. DNA degradation was found in 8% and 12% of DNA samples after 6 and 9 months of treatment, respectively, while DNA instability was detected in only 2% and 8% of DNA samples after 6 and 9 months of treatment, respectively. CONCLUSIONS The results showed that OS and genotoxicity slightly changed after treatment with a fixed orthodontic appliance; in addition, a biological adaptation response to the treatment may occur after 6 months. CLINICAL RELEVANCE OS and genotoxicity in the buccal cavity are risk factors for oral and systemic diseases. This risk may be reduced through antioxidant supplementation, by using thermoplastic materials, or by reducing the orthodontic treatment time.

Abstract
BACKGROUND The aim was to assess periodontal health maintenance and gingival recessions development in patients undergoing an orthodontic treatment with clear aligners (CA) and fixed appliances (FA). MATERIAL AND METHODS An electronic search in MEDLINE, Scopus, The Cochrane Library, and Web of Science was performed up to September 2022 to identify all potential articles. Two investigators independently selected the studies according to the inclusion criteria. Prospective and retrospective studies assessing the periodontal health status and gingival recession development during the orthodontic treatment with buccal FA and CA were included. Case series, cross-sectional studies, and studies with less than two months of follow-up were excluded. Two investigators independently extracted the data from included articles and assessed risk of bias across studies using the Cochrane Collaboration tool. Qualitative and quantitative analyses of the data were performed. Pairwise meta-analysis using a random-effects model were used to compare periodontal indices between FA and CA treatment in different follow-up periods. RESULTS From the 129 potential studies, finally 12 studies were included. Only 8 could be included in the quantitative analysis. CA seems to slightly maintain better periodontal health indices. Only plaque index in a mid-term follow-up (mean difference (MD): -0.99; 95%; Confidence interval (CI) [-1.94 to -0.03]; P=.04; I2=99%), and pocket probing depth at a long-term follow-up (MD: -0.93mm; 95% CI [-1.16 to 0.7]; P<0.0001) reported statistically significant results favoring CA. CONCLUSIONS Up to the date there is not enough evidence to conclude that CA maintains better periodontal health during an orthodontic treatment than FA.

Abstract
Orthodontic treatment has become increasingly popular due to its benefits in improving facial and smile aesthetics, self-esteem and the function of the stomatognathic apparatus. However, orthodontic appliances make it more difficult to brush teeth effectively, as they interfere with tooth brushing and facilitate the accumulation of dental plaque (biofilm), which induces a quantitative and qualitative change in the oral microbiota. It can cause several adverse effects, such as gingivitis, periodontitis, white spot lesions (WSL), caries and halitosis, induced by an increase in periodontopathogenic and cariogenic bacteria. Therefore, this article resumes the main findings on the changes in the oral microbiota induced by different orthodontic appliances (removable, fixed and clear aligners) and gives some practical strategies in order to reduce the impact and/or incidence of local dental/periodontal complications.

Abstract
OBJECTIVES To investigate the masticatory (masticatory performance, bite force, swallowing threshold, muscle activity, and questionnaires) and nutritional (nutrient intake) impacts of the activation and/or installation of different orthodontic appliances (fixed labial, lingual appliances, and clear aligners). MATERIALS AND METHODS Six electronic databases and gray literature were searched (up to May 2021) for relevant studies evaluating mastication and nutrition after activation/installation of orthodontic appliances. This review followed PRISMA guidelines and was registered at PROSPERO (CRD42020199510). The risk of bias (RoB 2 and ROBINS-I) and evidence quality Grading of Recommendations Assessment, Development, and Evaluation were analyzed. RESULTS Of 4226 recorded and screened, 15 studies were finally included. Masticatory performance (standardized mean difference [SMD]: 1.069; 95% coefficient interval [CI]: 0.619 to 1.518) and bite force (SMD: -2.542; 95% CI: -4.867 to -0.217) reduced in the first 24 to 48 hours of fixed labial appliance installation/activation, but they were both normalized after 30 days (P > .05). The swallowing threshold remained constant (P > .05). Nutritional intake was rarely reported but showed copper (P = .002) and manganese (P = .016) reductions, with higher calorie and fat intake (P < .05). Lingual appliances impacted chewing more than labial, and clear aligner wearers reported fewer chewing problems (P < .001). Low to very low levels of evidence were found. CONCLUSIONS Based on low to very low levels of evidence, mastication was reduced during the first 24 to 48 hours of fixed labial appliance activation/installation, but it was transitory (up to 30 days). Due to insufficient data, the nutritional impact of orthodontic appliances was not conclusive.

Abstract
Objective To explore the microbial diversity and community structure of dental plaques in orthodontic patients with invisible appliances and fixed appliances and to study the differences. Methods Ten orthodontic patients wearing invisible appliances (I) and ten wearing fixed appliances (F) were recruited. Dental plaques were collected from both buccal (B) and lingual (L) sides. Based on 16S rDNA, 40 dental plaque samples were analyzed after Illumina sequencing. Results The microbial diversity, abundance and evenness of the FB group were significantly higher than those of the IB and IL groups (P<0.05), while the FL group showed substantial individual differences. The community structures were generally similar among the four groups, but significant differences in the relative abundance of some bacteria were found. The IB group showed higher abundances of Actinomycetes and Rosella (P<0.05), which were considered to be involved in dental caries and periodontal diseases. Some key communities showing significant differences were significantly enriched in the FB group, including Coprobacillus, Bifidobacterium, Enterobacterium, Lactobacillus, etc.. Conclusion Dental plaques in patients wearing invisible appliances and fixed appliances showed significantly different microbial abundance, diversity and composition, which may be involved in orthodontic complications such as dental caries and periodontal diseases. Orthodontic patients need strengthened measures for oral hygiene maintenance, no matter what kind of appliances they wear.

Abstract
BACKGROUND Good oral hygiene is very important to ensure successful orthodontic treatment. Orthodontic treatments may cause plaque accumulation and in this way the development of caries and periodontal diseases which are basically caused by dental plaque. The aim of this study was to compare the features of oral hygiene among different age groups and genders in patients with fixed orthodontic appliances. MATERIAL AND METHODS The study involves 118 patients aged 12 to 18 (64 males (54.2%) and 54 females (45.8%)) with fixed orthodontic appliances from the Department of Orthodontics at Danylo Halytskiy Lviv National Medical University. The patients completed the questionnaires which included 19 questions about their oral hygiene. RESULTS It was revealed that 59 females (92.19±3.35%) believe that oral hygiene is important, but among the males number of such persons have been significantly lower - 41 (75.93±5.82%), p<0.05. Statistically significant result was obtained showing that females (46 patients (71.88±5.62%) use interdental brushes more regular (every day) than males (26 (48.15±6.80%), p<0.05. Comparing the differences between the regularity of teeth brushing in different age groups showed that 53 patients (82.81±4.72%) aged 12 to 15 and 46 (85.19±4.83%) aged 16 to 18 claimed that they brush their teeth regularly, twice a day, 8 (12.50±4.13%) and 6 (11.11±4.28%), respectively - once a day. CONCLUSION In patients with fixed orthodontic appliances oral hygiene of 16-18-year-old respondents is better than the oral hygiene of 12-15-year-old ones.

Abstract
Orthodontic treatment can lead to microbial-induced gingival inflammation and aseptic periodontal inflammations. The aim of this study was to investigate the relationship between salivary pro-inflammatory cytokines levels with gingival health status and oral microbe loads among patients undergoing orthodontic treatment.The present investigation was a cross-sectional study among a sample of 111 consecutive orthodontic patients (mean age 18.4 ± 4.4 years). Clinical examinations were conducted to assess the gingival health status employing the Modified Gingival Index, Gingival Bleeding Index, and Plaque Index. Salivary microbiological assessments of total aerobic and anaerobic bacteria count, streptococci count, and lactobacilli count were undertaken. Saliva immunological assessments included Interleukin-1Beta (IL-1β) and macrophage migration inhibitory factor (MIF) ELISA assays.The mean ± standard deviation of salivary IL-1β was 83.52 ± 85.62 pg/ml and MIF was 4.12 ± 0.96 ng/ml. Moderate positive correlations were found between salivary IL-1β levels and total aerobic and anaerobic bacteria count, streptococci count, and lactobacilli count (r = 0.380-0.446, P < .001), and weak positive correlations between salivary MIF levels and total salivary aerobic and anaerobic bacteria counts (r = 0.249-0.306, P < .01) were observed. A positive correlation was found between salivary IL-1β levels and Bleeding Index (r = 0.216, P < .05).The level of salivary IL-1β positively correlates with oral bacterial load among orthodontic patients; the relationship between inflammatory cytokines and oral microflora deserved further study.

Abstract
OBJECTIVES To evaluate the effect of orthodontic appliances on physicochemical, biochemical, and oxidative stress changes in salivary parameters during treatment. MATERIALS AND METHODS A cohort study was conducted with 112 healthy patients. Salivary samples were taken at baseline, 1 month, and 9 months after placement of the orthodontic appliances used in treatment. RESULTS A statistically significant difference was observed in certain examined salivary parameters, including enzymes, electrolytes, and oxidative stress markers. CONCLUSIONS The use of aligners had a lower prevalence of disturbing salivary parameters. Orthodontist must consider these changes to prevent the occurrence of white spot lesions.

Abstract
PURPOSE To evaluate the association between orthodontic treatment with fixed appliances and periodontal health during treatment by examining gingival inflammation indices and saliva properties. MATERIALS AND METHODS Thirty consecutive orthodontic patients, aged 11-18 years old, who were eligible for fixed orthodontic appliances, were included in the study. Plaque index (PI), gingival index (GI), salivary pH and flow rate were recorded at three timepoints: immediately before placement of orthodontic fixed appliances (T0), and 1 (T1) and 3 months (T2) after bonding. RESULTS The hypothesis that PI would remain constant across timepoints was rejected. PI increased over time (0 to 1 scale, T1-T0: mean diff. = 0.10, 95% CI = 0.03, 0.18, p = 0.01; T2-T0: mean diff. = 0.16, 95% CI = 0.08, 0.24, p < 0.001). On the other hand, GI changed statistically significantly over time (p = 0.05). Patients' age was not a predictor for PI change (p = 0.93), but it was for GI (p = 0.01). As anticipated, average PI was found to be higher for the mandibular dentition by 0.10 (95% CI = 0.04, 0.16) and the labial surfaces of teeth of both jaws by 0.51 (95% CI = 0.45, 0.57). CONCLUSIONS Within the framework of the current study, orthodontic treatment appeared to affect the periodontal health of patients, but the changes were clinically negligible and not consistently statistically significant.

Abstract
PURPOSE To identify and assess differences in oral hygiene parameters in patients undergoing orthodontic treatment with clear aligners compared to fixed appliances. MATERIALS AND METHODS Published and unpublished literature was searched in seven databases until May 31st 2021. Representative keywords included 'orthodontic aligner', 'fixed appliance', 'oral hygiene', 'plaque index', 'caries'. Study selection, data extraction, risk of bias and certainty of evidence assessment were undertaken independently by three reviewers. Random effects meta-analyses with respective confidence intervals (95% CI) were conducted, where applicable. RESULTS A total of 882 unique records were screened, with a final number of 21 articles being eligible for qualitative synthesis, while 4 of those contributed to meta-analyses. Risk of bias was rated within the range of low to high or serious overall, while certainty of evidence was low to very low according to GRADE. For periodontal parameters, adults undergoing aligner orthodontic treatment presented summary plaque scores 0.58 lower than those treated with fixed appliances, within the first 6 to 12 weeks (4 studies: mean difference: -0.58; 95%CI: -0.82, -0.34; p < 0.001; I2 squared: 71.3%), while no evidence of difference was recorded for inflammation indices. Microbiologic parameters such as presence of S. mutans and lactobacilli were more pronounced in patients with fixed appliances for the first 3 to 6 months (synthesised data from 2 studies). CONCLUSIONS In the short-term after initiation of orthodontic treatment, patients treated with aligners and no additional attachments/adjuncts presented potentially higher levels of oral health overall. However, the evidence is supported by low to very low certainty.

Abstract
BACKGROUND The oral hygiene habits of clients wearing fixed orthodontic appliances is poorly understood. Assessment of oral hygiene behavioural patterns is essential for understanding clients' oral health care needs. The aim of this study was to investigate orthodontic clients' oral hygiene behaviours, brushing techniques, and oral hygiene awareness. METHODS A total of 200 orthodontic clients wearing fixed orthodontic appliances were consecutively recruited from the Sichuan Provincial Hospital, Chengdu, China, and the Faculty of Dentistry, University of Otago, Dunedin, New Zealand. A 47-item questionnaire was used to survey study participants. RESULTS The survey had a 92% response rate, with 67.5% of respondents being female and 32.5% male. Most were non-smokers (94.2%) and the majority (80.0%) brushed their teeth twice daily. Most (80.4%) brushed their teeth for 1 to 2 minutes, and 68.7% positioned their toothbrush both horizontally and vertically, with horizontal being the preferred direction of motion. One-third (33.5%) did not use any auxiliary oral hygiene aids; most snacked between meals; only 31.4% received professional tooth cleaning during orthodontic treatment; and 56.8% experienced an increased level of halitosis after appliance placement. Most respondents (79.4%) thought their oral hygiene was good, but 51.0% reported bleeding gums during tooth brushing, 31.4% found they rarely bled, and only 17.6% reported no bleeding. Most respondents agreed that good oral health was very important for orthodontic treatment and that their own efforts were the most important factors. CONCLUSIONS Client awareness of the importance of oral hygiene during orthodontic treatment requires improvement. Clinician reinforcement of oral hygiene should become a priority for orthodontic clients.

Abstract
Elastomeric ligatures are increasingly used as a part of esthetic orthodontic treatment, particularly in children. The aim of the present study was to experimentally test whether these appliances may contribute to exposure to toxic elements. In the present study, elastomeric ligatures (ELs) were incubated in artificial human saliva for 1 month (a typical period of their use) and the release of 21 metals (Ba, Cd, Co, Cr, Cu, Fe, Li, Mn, Mg, Mo, Ni, Pb, Rb, Tl, Ti, Sb, Sr, Sn, Zn, U, V) and 2 metalloids (As and Ge) was studied using inductively coupled plasma-mass spectrometry. For comparison, stainless steel ligatures (SLs) were incubated for 1, 3, and 6 months (since sometimes their use is prolonged) under similar conditions. The determined metal levels were compared to the corresponding safety limits for human exposure. During 1 month, the ELs released Cd, Co, Cr, Mn, Ni, and Sn at total mean ± SD level of 0.31 ± 0.09, 0.98 ± 0.30, 3.96 ± 1.31, 14.7 ± 8.5, 13.8 ± 4.8, and 49.5 ± 27.7 μg, respectively. Other elements were always below the detection limits. In case of SL, the release of Co, Cr, Fe, Ni, Mn, and Sn was observed, and the determined values increased over the studied period. After 6 months, their total mean ± SD levels amounted to 28.6 ± 0.2, 21.7 ± 0.2, 623.5 ± 3.0, 1152.7 ± 1.8, 5.5 ± 0.3, and 22.6 ± 0.2 μg, respectively. The released metal levels from both ligature types were always below safety limits. The release of Ni from SL during 6 months would constitute 5.0 and 11.5% of tolerable intake in adults and children, respectively. The results of this in vitro study highlight that the use of ligatures in orthodontic treatment can be considered safe in terms of metal exposure although elastic ligatures replaced on a monthly basis appear to be advantageous in comparison to the prolonged use of stainless steel appliances.

Abstract
BACKGROUND The prevalence of white spot lesions/tooth demineralization during orthodontic fixed appliance therapy ranges widely from 2 to 96% of patients. The purpose of this study was to evaluate measures used by orthodontists practicing in Nigeria to manage demineralization during and after fixed orthodontic treatment and how it compares with the available evidence-based information. METHOD Study group comprised of 60 practitioners (21 orthodontists and 39 orthodontic residents) in Nigeria. Self-administered questionnaires were used to obtain information on the measures they use to prevent the occurrence of demineralization at the onset and during orthodontic treatment, as well as the management of its occurrence at treatment completion. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) software, version 17.0. Descriptive statistics were used. Level of significance was set at P < 0.05. RESULTS Responses obtained showed that 96.7% of orthodontic practitioners routinely advised their patients on tooth cleaning methods; the use of manual orthodontic toothbrush (78.3%) and dental floss (51.7%) being popularly recommended methods. However, 51.7% used a specific demineralization preventive protocol at the start of treatment. Oral hygiene instruction was observed to be the most commonly adopted protocol (51.7%), followed by fluoride rinses (41.7%) (considered relatively ineffective). Extraoral hygiene instruction was the most common treatment protocol used when tooth demineralization occurred during and after treatment (56.7% and 73.3% respectively). Approximately 92% of the orthodontists agreed on the need for the development of a basic protocol to prevent demineralization. CONCLUSION The demineralization preventive measures used by Nigerian orthodontists and orthodontic residents are inconsistent and not based on evidence-based information. The development of standardized demineralization prevention protocol was therefore recommended.

Abstract
BACKGROUND Treatment with fixed orthodontic appliances has been associated with significant biofilm accumulation, thus putting patients at a higher risk of oral health deterioration. The use of probiotics has been proposed to be useful in the prevention or treatment of oral pathologies such as caries and diseases of periodontal tissues. Our aim was to investigate the effects of probiotic use on inflammation of the gingival tissues and the decalcification of the enamel in patients being treated with fixed orthodontic appliances. METHODS We searched without restrictions 8 databases and performed hand searching until September 2019. We searched for randomized controlled trials (RCTs) evaluating whether individuals with fixed orthodontic appliances benefit from probiotic treatment in terms of the inflammation of the gingivae and decalcification of the enamel. Following the selection of studies and the extraction of pertinent data, we appraised the risk of bias and the confidence in the observed effects based on established methodologies. RESULTS From the final qualifying studies, three did not show any statistically significant effect on gingival inflammation after probiotic administration of up to 1 month. Similarly, non-significant differences were noted in another study regarding white spot lesions development (mean administration for 17 months). No adverse effects were reported and the level of evidence was considered moderate. CONCLUSIONS Supplementation of orthodontic patients with probiotics did not affect the development of inflammation in the gingivae and decalcification in the enamel. Additional RCTs, with longer intervention and follow-up periods, and involving different combinations of probiotic strains are required. TRIAL REGISTRATION PROSPERO (CRD42018118008).

Abstract
OBJECTIVE To evaluate the cytotoxicity of stainless-steel orthodontic bands and their influence on the expression of the antioxidant genes in human gingival fibroblasts. MATERIALS AND METHODS Ten bands of each brand (Dentsply-Sirona, Dentaurum, TP Orthodontics, and Morelli) were conditioned in 0.2 g/mL culture medium at 37°C for 14 days, and the corresponding conditioned media were applied over the fibroblasts. Cell viability was assessed after 24, 48, and 72 hours of exposure to the conditioned media by trypan blue exclusion assay. Expression of the antioxidant defense genes peroxiredoxin 1 (PRDX1), superoxide dismutase 1 (SOD1), and glutathione peroxidase 1 (GPX1) were evaluated by quantitative polymerase chain reaction after 24 hours of exposure. These parameters were compared to those of the cells not exposed to the conditioned media of the bands (control). RESULTS All bands promoted a reduction in the number of viable cells in the periods of 48 and 72 hours (P < .01). Analysis of gene expression showed a significant increase in the levels of PRDX1 transcripts caused by the conditioned media of the Dentsply-Sirona, TP Orthodontics, and Morelli bands (P < .01) as well as induction of SOD1 by the conditioned media of the Dentaurum and Morelli (P < .01). Expression of GPX1 was not influenced by the conditioned media. CONCLUSIONS The orthodontic bands showed toxicity to fibroblasts and increased the expression of PRDX1 and SOD1 antioxidant genes, indicating induction of oxidative stress in the cells.

Abstract
BACKGROUND Pain stemming from the placement of elastomeric separators and the exchanging of wires and accessories is the greatest reason for abandoning orthodontic treatment. Indeed, discomfort related to treatment exerts a negative impact on quality of life due to the difficulty chewing and biting. This paper proposes a study to evaluate the analgesic effects of photomiobodulation (PBM) on individuals undergoing orthodontic treatment. METHODS The sample will be composed of 72 individuals who receiving elastomeric separators on the mesial and distal faces of the maxillary first molars. The patients will be randomly allocated to 2 groups: an experimental group irradiated with low-level laser and a sham group submitted to simulated laser irradiation. Upon the placement of the separators, the experimental group will receive a single application of PBM on the mesial and distal cervical portion and apical third of the molars. Perceived pain will be analyzed after one hour using the visual analog scale in both groups. Samples will be taken of the gingival crevice with absorbent paper for 30 seconds for the analysis of cytokines using ELISA and the results of the 2 groups will be compared. The patients will sign a statement of informed consent. Statistical analysis will be performed with the Student's t test and analysis of variance (ANOVA). DISCUSSION The expectation is that the patients in the irradiated group will have a lower perception of pain and lower quantity of cytokines compared to those in the sham group. The purpose of the study is to establish an effective method for PBM with the use of low-level infrared laser (Ga-Al-As with a wavelength of 808 nm and output power of 100 mW) for reductions in pain and inflammatory cytokines related to orthodontic treatment. TRIAL REGISTRATION This protocol was registered in ClinicalTrial.gov, under number NCT03939988. It was first posted and last updated in May 6, 2019.

Abstract
Spacing between the maxillary anterior teeth is a common concern for young patients and their parents. Patients often consider a diastema to be an annoying but minor problem; they might consult their general dentists for help, or try to address the issue themselves by applying elastic "gap bands." Moreover, parents, without any informed consent, sometimes accept this erroneous method as an easy and inexpensive treatment approach. A 9-year-old boy had severe acute periodontitis involving the maxillary central incisors caused by the placement of an elastic band and its apical migration. Despite periodontal and surgical interventions, the maxillary central incisors were finally extracted, and the patient started orthodontic treatment. The orthodontic treatment plan included maxillary lateral incisor substitution to replace the lost central incisors and mesialization of the maxillary posterior dentition. An interdisciplinary approach with excellent cooperation among the orthodontist, general dentist, and other dental specialists obtained an esthetically pleasing and optimized functional result. Treating the diastema between the anterior teeth with elastic gap bands and without fixed orthodontic appliances should be avoided. Patients should seek proper orthodontic advice for even small-scale orthodontic problems to prevent catastrophic outcomes, as exhibited in this case report.

Abstract
AIM The current study was aimed to determine the relationship between the orthodontic force applied by monobloc and the salivary level of alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) enzymes, considering the time factor after insertion of the appliance and whether there is a correlation between these enzymes. MATERIALS AND METHODS A sample of 28 growing patients requiring orthodontic treatment with myofunctional appliance (Monoblock) was taken for the current study with an age range 9 to 12 years,all patients had Angle's class II division 1 mal-occlusion with no or mild crowding, the sample was selected using simple random sampling. Only 16 subjects (10 males and 6 females) were included who follow certain inclusion criteria. Unstimulated saliva was collected from the patients before monoblock insertion, then 1 hour after insertion, followed by 14 days and 28 days. Salivary levels of ALP and LDH were measured using a spectrophotometer and compared with the base line. RESULTS The results revealed that ALP and LDH levels increased with increasing time after monoblock insertion, and there was the statistically insignificant difference after 1-hour post-insertion for ALP enzyme level, but highly significant after 14 and 28 days. While for LDH level,there was the statistically significant difference after 1-hour post-insertion, but highly significant difference after 14 and 28 days post-insertion. In this regard to the relation between salivary ALP and LDH enzymes levels at different time intervals, showed that there were no significant correlations between the enzymes using Pearson's correlation test. CONCLUSION The ALP and LDH salivary enzymes activity is affected by mechanical forces generated by monobloc activator and these enzymes activities can also be increased during the rapid growth phase of childhood such as late infancy and early puberty where the age of subjects was selected in the current study. CLINICAL SIGNIFICANCE The determination of ALP and LDH salivary enzymes activities during the skeletal maturity is crucial for the success of myofunctional monobloc treatment; therefore, saliva can be used as a noninvasive diagnostic tool for determination of chemical biomarkers for detection of bone remodeling process during myofunctional monoblock treatment Keywords: Alkaline phosphatase (ALP), Lactate dehydrogenase (LDH), Monoblock, Orthodontic force, Salivary levels.

Abstract
RATIONALE Streptococcus viridans, a heterogeneous group of alpha-hemolytic streptococci, is part of the normal flora of the mouth, usually responsible for dental caries (Streptococcus mutans, Streptococcus sanguinis), and pericoronitis, as well as for subacute infective endocarditis. They are responsible for 40-60% of the endocarditis cases occurring on the normal valves, especially in male patients and over 45 years of age. A change in the bacterial flora of the oral cavity is taking part after orthodontic fixed appliances are introduced into the oral cavity, change that is associated with an increased concentration of the acidogenic bacteria. Bacteraemia is the consequence of oral cavity infections, the association of infective endocarditis with fixed orthodontic appliance, as it has been described by us for the first time, caused by Abiotrophia defectiva. PATIENT CONCERNS We present the case of a female Caucasian patient, aged 22 years, who developed infective endocarditis with Streptococcus viridans associated with fixed orthodontic appliance, located on the mitral valve, without previous cardiac pathology, and the therapeutic difficulties associated with allergic reactions (to vancomycin, and spironolactone). DIAGNOSES Repetitive haemocultures were positive with Streptococcus viridans, while transthoracic echography revealed a severe mitral failure through anteromedial segment of the anterior mitral valve leaf prolapse with eccentric jet to the posterior wall. INTERVENTIONS During hospitalization, the decision to undergo surgical intervention was taken after obtaining negative haemocultures. The patient underwent surgically intervention, and a mitral valve plasty with insertion of neochords was performed. OUTCOMES Intraoperative and subsequently post-discharge transesophageal echography, highlighted normofunctional mitral plasty with a remaining regurgitation grade I-II of IV, with good openness, minor tricuspid regurgitation, and mild pulmonary hypertension. LESSONS Endocarditis with oral streptococci associated with fixed orthodontic appliance seems to be not so unlikely even in young or without previous cardiac pathology patients, requiring attention in identifying possible pre-existing cardiac conditions like mitral valve prolapse with clinical and echographic monitoring of such cases. Educating and motivating the patient to observe the oral hygiene represent key steps for an optimal oral health during orthodontic treatment. Mechanical tooth cleaning helps maintaining a good oral hygiene during fixed orthodontics and decreasing the oral health risks.

Abstract
This study investigated the effect of the period of use and location of intraoral appliances on enamel surface loss. This randomized, single blind in situ study was conducted in 2 crossover phases based on the period of use, in which maxillary and mandibular appliances were simultaneously worn. Bovine enamel blocks (n = 120) were randomly divided among the studied groups by surface hardness. In each phase, fifteen volunteers used one maxillary appliance and two mandibular appliances for 5 days. Erosive challenge was performed 4X/day by immersion in 0.01 M HCL for 2 minutes. In the continuous phase, the intraoral appliances were worn for 20 hours. In the intermittent phase the appliances were worn for 8 hours and 30 minutes. Enamel loss was determined profilometrically. The discomfort of use of the appliances were evaluated in a questionnaire. Data were analyzed by two-way ANOVA/Tukey’s test and chi-square test (p<0.05). The maxillary appliance promoted higher enamel loss compared to the mandibular one (p<0.001). Intermittent use of appliances resulted in similar enamel loss to the continuous one (p = 0.686). All volunteers preferred to use the maxillary appliance in an intermittent regimen. The intermittent use of maxillary appliance is a simplified reliable protocol appropriated for in situ erosion studies in enamel.

Abstract
BACKGROUND One of the first concerns of new orthodontic patients, apart from the outcome, is the duration of treatment. A better understanding of orthodontic treatment duration as well as factors affecting the treatment duration is useful for efficient patient counselling and improved clinical practice. Hence, the objectives of this study are to compare the treatment durations of subjects with Class I and Class II division 1 (II/1) malocclusions, and to identify the factors affecting the treatment duration of these malocclusions. METHODS This was a chart review conducted in the orthodontic department of the Aga Khan University Hospital, Karachi. The study sample comprised of 120 subjects and data were recorded from their treatment records. ANOVA and Bonferroni post-hoc were performed to determine the difference in treatment durations of Class I and Class II/1 malocclusions, whereas multiple linear regression was applied to identify the factors affecting the treatment duration. A level of significance (p≤0.05) was used for the statistical tests. RESULTS A statistically significant difference was found between the treatment durations of Class I and Class II/1 non-extraction (p=0.007), Class I non-extraction and Class II/1 extraction (p=0.001), and Class I and II/1 extraction (p=0.004) groups. The factors significantly increasing the treatment duration included missed appointments, breakages, and lower incisor proclination. CONCLUSIONS Orthodontic treatment of Class II/1 malocclusion lasts longer than that of Class I malocclusion. Prolonged treatment time is associated with missed appointments, band/bracket debonds and increased lower incisor inclination. The variance in treatment time can be explained most significantly by number of missed appointments and breakages.

Abstract
The objective was to investigate the effect of dietary habits on the release of Cr and Ni ions from orthodontic appliances by hair mineral analysis. Patients (N = 47) underwent electronic questionnaire survey to investigate the effect of dietary habits on Cr and Ni levels in hair. The research was carried out on hair sampled at the beginning and in the 4th, 8th, and 12th months of the treatment. The content of Cr and Ni in the collected samples was determined by ICP-OES. The study showed that consumption of acidic dietary products may have the effect on increasing the release of Cr and Ni ions from orthodontic appliances. The release of Cr from orthodontic appliances in patients who consumed fruit juice, coffee, yoghurt, and vinegar was higher. The coefficients enabling comparison of metal ions release pattern at a given sampling points were defined. The comparison of the coefficients yielded the information on the possible magnification of metal ions released as the result of the additional factor consumption of acidic food or drink that intensifies metal ions release. The following magnification pattern was found for chromium: coffee (7.57 times) > yoghurt (2.53) > juice (1.86) > vinegar (1.08), and for nickel: vinegar (2.2) > coffee (1.22) > juice (1.05). Yoghurt did not intensify the release of nickel. Concluding, orthodontic patients should avoid drinking/eating coffee, yoghurt, fruit juices, and vinegar.

Abstract
An overview of professional literature referring to the release of metal ions from fixed orthodontic appliances and their influence on oral mucosa in conditions of in vivo are presented, along with a detailed analysis of the exposure of the cells of cheek mucosa epithelium to metal ions. Electronic databases (PubMed, Elsevier, Ebsco) were searched with no language restrictions. The relevant orthodontic journals and reference lists were checked for all eligible studies. A total of 38 scientific articles were retrieved in the initial search. However, only 7 articles met the inclusion criteria. Statistically significant differences in the levels of the amount of nickel ions, cobalt ions and chromium ions were observed in cells of cheek mucosa. The most biocompatible material used in the production of fixed orthodontic appliances is titanium, and the least biocompatible material is steel, which releases the largest amount of nickel and chromium. Metal ions are released from fixed orthodontic appliances only in the first phase of treatment. It is recommended to conduct further, long-term research on a larger number of patients to define the influence of using fixed orthodontic appliances and biological effect they might have on tissues.

Abstract
INTRODUCTION The aim of this systematic review was to assess the prevalence of adverse effects associated with lingual and buccal fixed orthodontic techniques. METHODS Two authors searched the PubMed, EMBASE, Cochrane Library, and LILACS databases up to October 2014. Agreement between the authors was quantified by the Cohen kappa statistic. The following variables were analyzed: pain, caries, eating and speech difficulties, and oral hygiene. The Newcastle-Ottawa scale was used to assess risk of bias in nonrandomized studies, and the Cochrane Collaboration's tool for assessing risk of bias was used for randomized controlled trials. RESULTS Eight articles were included in this systematic review. Meta-analysis showed a statistically greater risk of pain of the tongue (odds ratio [OR], 28.32; 95% confidence interval [95% CI], 8.60-93.28; P <0.001), cheeks (OR, 0.087; 95% CI, 0.036-0.213; P <0.0010), and lips (OR, 0.13; 95% CI, 0.04-0.39; P <0.001), as well as for the variables of speech difficulties (OR, 9.39; 95% CI, 3.78-23.33; P <0.001) and oral hygiene (OR, 3.49; 95% CI, 1.02-11.95; P = 0.047) with lingual orthodontics. However, no statistical difference was found with respect to eating difficulties (OR, 3.74; 95% CI, 0.86-16.28; P = 0.079) and caries (OR, 1.15; 95% CI, 0.17-7.69; P = 0.814 [Streptococcus mutans] and OR, 0.67; 95% CI, 0.20-2.23; P = 0.515 [Lactobacillus]). CONCLUSIONS This systematic review suggests that patients wearing lingual appliances have more pain, speech difficulties, and problems in maintaining adequate oral hygiene, although no differences for eating and caries risk were identified. Further prospective studies involving larger sample sizes and longer follow-up periods are needed to confirm these results.

Abstract
PURPOSE The aim of our study was to analyse salivary markers of oxidative stress and an antioxidant response in clinically healthy subjects with fixed orthodontic appliances. MATERIAL/METHODS 37 volunteers were included in the study. Unstimulated (UWS) and stimulated (SWS) whole saliva were analysed for oxidative and antioxidant status and nickel levels immediately before the insertion of the appliances, an one week after and twenty four weeks after the insertion of fixed appliances. RESULTS A significant increase in tiobarbituric acid reactive substance (TBARS) and total oxidant status (TOS) one week, and total protein concentration twenty four weeks after the attachment of orthodontic appliances was found in the saliva. The markers of antioxidant status: superoxide dismutase (SOD), catalase (CAT), uric acid (UA), peroxidase (Px), and total antioxidant status (TAS) were not changed in all periods in UWS. In SWS a significant decrease in SOD1 and CAT was found whereas Px was increased one week after treatment and UA twenty four weeks following treatment. TAS was decreased in UWS and SWS twenty four weeks after orthodontic treatment. Oxidative status index (OSI) was elevated both in UWS and SWS one week after orthodontic treatment in comparison to the results obtained before and twenty four weeks. One week after treatment an increased concentration of nickel was also observed. CONCLUSIONS Orthodontic treatment modifies the oxidative-antioxidative balance in the saliva of clinically healthy subjects. Increased nickel concentration in saliva, released from orthodontic appliances, seems to be responsible for changes in the oxidative status of the saliva.

Abstract
INTRODUCTION Treatment of teeth anomalies using removable and non-removable orthodontic devices in children leads to complications such as caries, gingivitis, periodontitis, oral mucosa hyperplasia. Etiopathogenetical of these diseases can be associated with biochemical changes in the composition of saliva. AIM To determine the activity of lysozyme and amylase in oral fluid in children when using a fixed and removable orthodontic devices. MATERIALS AND METHODS Amylase and lysozyme were studied in oral fluid. Analyzed the biochemical composition of the freshly samples of oral fluid that was obtained in the control, experimental group 1 and 2 (children ages 7-18 years, which were used medical non-removable and removable orthodontic devices). Saliva was collected at the beginning of the therapeutic use of orthodontic devices (the first day of treatment), on 3 and 6 months of treatment. Assessment of lysozyme activity was carried nephelometric method on the ability of lysozyme to dissolve indicator organism Micrococcus lysodeicticus. To construct a calibration graph using dry lysozyme company Sigma. Salivary amylase activity was determined by hydrolysis of starch. The results were subjected to statistical analysis by standard methods. Data processed using software packages applied statistical analysis Statistica 6.0, Microsoft Excel, 2003. RESULTS The use of a fixed and removable orthodontic equipment led to a decrease in saliva amylase, major changes are observed on the 6th month of treatment. The activity of lysozyme in saliva decreased the mostin patients with a permanent equipment. Major changes were also recorded on the 6th month of treatment. CONCLUSIONS Complications of orthodontic treatment teeth anomalies in children (caries, gingivitis, periodontitis) caused by changes in the biochemical composition of saliva. For the prevention of the emergence and development of these complications is necessary to control the level of amylase and lysozyme in the mouth.

Abstract
PURPOSE To confirm that the quantitative light-induced fluorescence-digital (QLF-D) system is an adequate tool for monitoring changes in the mineral contents of white spot lesions. MATERIALS AND METHODS Twenty-three anterior teeth from five orthodontic patients were selected for the samples. Initial fluorescent images were taken with the QLF-D system immediately after removing the fixed orthodontic appliances, and the white spot lesions were visualised in the fluorescent images that were selected. Subsequently, a fluoride varnish containing 0.1% fluoride was applied to all white spot lesions, and the final QLF-D images were taken two weeks after fluoride treatment. Finally, the following four parameters were compared between the images taken at baseline and two weeks after the treatment with paired t-tests: the mean fluorescence loss (∆F), maximum fluorescence loss (∆Fmax), lesion area (area), and lesion volume (∆Q). RESULTS All the parameters obtained by QLF-D after two weeks had improved significantly when compared with baseline (p < 0.01). The recovery rates of the ∆F, ∆Fmax, area, and ∆Q were 11.4%, 17.1%, -37.5%, and 42.1%, respectively. Shallow lesions (∆Fi ≥ -15%) were better remineralized than deep lesions (∆Fi < -15%). The ratios of the ∆F, ∆Fmax, area, and ∆Q parameters between the shallow and deep lesions were 2.86, 3.30, 2.20, and 1.88, respectively. CONCLUSION The QLF-D system is a sensitive tool for the assessment of small levels of mineral changes in carious lesions after the removal of orthodontic appliances.

Abstract
Orthodontic therapy, like any other medical intervention, in addition to its benefits carries the risk of potential complications and is associated with adverse effects-including periodontal problems, external root resorptions, pulpal changes, enamel damages (demineralization, discoloration, attrition), temporomandibular disorders, infective endocarditis, soft tissue damages, discomfort, pain and the risk of either aspiration or indigestion of medical instruments and appliances. Usually these effects are multifactorial in origin- most often a result of interactions between the patient, the dental practitioner and the technical aspects of the appliances or techniques. With preventive measurements and care, most of these complications can be either limited or completely avoided. Therefore, every dental practitioner must be fully aware of these effects and associated risk factors in order to maximize the treatment outcome. The present review aims to summarize these effects of orthodontic therapies, and provide a detailed description of factors and preventive measures, in order to minimize these damages.

Abstract
INTRODUCTION Bisphenol A (BPA) is a synthetic chemical substance used as a starting ingredient in the manufacturing process of a number or orthodontic materials. It is a well-known endocrine disruptor with low estrogenic properties. The aim of this investigation is to present a systematic review regarding the issue of bisphenol A release by orthodontic materials and its impact in orthodontics. MATERIALS AND METHODS A systematic analysis was performed by electronic search (between 1936 and 2015) on several data bases. The search was limited by using several specific key-words in two languages, English and French. Two investigators selected the responses, which met the selection criteria. RESULTS AND DISCUSSION Of the 376 studies found, only 21 met our selection criteria: 11 of these dealt with the release of bisphenol by orthodontic materials and 10 in vitro studies described the effects of BPA leaching from orthodontic materials on human and murine cells. The rate of BPA release was well below the daily tolerable intake (DTI) (50mg/kg/day in 2006, then 50μg/kg/day in 2015) according to the European Food Safety Authority (EFSA). Theoretical exposure to BPA was 11,000 times lower than recommendations. However, other studies have shown the presence of BPA and of monomers released in large quantities at very low doses. The effects of observed BPA varied significantly (toxic and carcinogenic potential) while some studies found no effects at all. The relatively small number of studies dealing with the release of Bisphenol A by orthodontic materials, apart from orthodontic materials and their significant biological effects, has led to the absence of standard protocols and has hindered precise determination of released BPA. Moreover, the lack of coherence between the various methodological approaches and variations in the experimental protocols have resulted in a low level of proof regarding the impact of BPA by orthodontic materials. RECOMMENDATIONS Through this study, the authors encourage clinicians to observe the following recommendations designed to reduce the amount of BPA released by materials used in orthodontics: keep the tip of the light-curing lamp as close as possible to the composite and perform indirect rather than direct light-curing; Pumice-polish the composite after bonding so as to reduce the potential amount of BPA released; reduce exposure by brushing or rinsing with a mouthwash during the first hour after bonding; follow a standardized, reproducible and expert-validated research protocol aimed at better understanding of BPA release.

Abstract
OBJECTIVE The aim of the study is to evaluate the effectiveness of fluoride and casein topical preparations in the prevention of white spot lesions during and after fixed orthodontic treatment. MATERIAL AND METHODS Information search for controlled studies on humans published in the English language between 2008 and 2013 was conducted in Medline via PubMed, ScienceDirect, and Oxford University Press: Oxford journals and The Cochrane Library, as well as the Web search Google Scholar. 177 articles were reviewed; eleven clinical studies fulfilled all inclusion criteria. RESULTS In the clinical studies it was concluded that high-concentration fluoride supplements are effective in reducing white spot lesions. Results of the studies showed the same usefulness of fluoride varnish, MI Paste, and usual oral hygiene using 1100 ppm of fluoride toothpaste. Effect on the prevention and treatment of white spot lesions of oral hygiene with toothpaste containing 1450 ppm of fluoride in orthodontic patients was evaluated. The positive effect of casein phosphopeptide-amorphous calcium phosphate in white spot lesions treatment was found. Otherwise in some clinical studies use of casein derivates during fixed orthodontics for white spot lesions treatment was not effective. CONCLUSIONS More clinical studies conducted during last five years yielded significantly positive results about the effectiveness of fluoride and caseine supplements in ameliorating white spot lesions during and after fixed orthodontic treatment. For a higher-risk patient group, additional supplements such as high-concentrated fluoride varnish, chewing sticks, or casein derivates, are required. A good oral hygiene regimen using high-fluoride toothpaste is as effective as fluoride or casein derivates in the prevention of new white spot lesions formation.

Abstract
OBJECTIVE To compare external root resorption (ERR) when bands and wires are used as orthodontic anchorage during rapid maxillary expansion (RME). MATERIALS AND METHODS Histologic analysis was performed on 108 sites from 18 maxillary first premolars and on 36 sites from six mandibular first premolars in nine subjects (mean age = 15.2 ± 1.4 years) 3 months after RME. Maxillary teeth were pooled into two groups (n = 54 each) according to the type of orthodontic anchorage (band group [BG] vs wire group [WG]). Anchorage type was randomly chosen in a split-mouth design. Mandibular first premolars, which were not subjected to orthodontic forces, were used as the control group (CG). RESULTS All premolars in the BG and WG showed ERR at the level of the cementum and dentin. Repair with cementum cells was observed in all resorption areas, but complete repair was rarely found. No statistically significant difference was found between the BG and WG with regard to the ERR. No association was found between the root height position (middle or cervical third) and the incidence of ERR. Buccal root surfaces showed a higher amount of ERR compared with the palatal and interproximal surfaces. ERR was not found in any teeth in the CG. CONCLUSION All maxillary first premolars subjected to RME showed ERR and partial cementum repair. Banded teeth did not develop more ERR than nonbanded anchorage teeth.

Abstract
Ingestion/aspiration episodes of foreign bodies are potential complications in almost all branches of dentistry. Occasionally, orthodontic appliances or small orthodontic components are accidentally swallowed and have caused problems with either the airway or the gastrointestinal tract, especially where the patient is supine or semi-recumbent. Despite their rare occurrence, the morbidity from a single incident and the level of specialized medical care that may be needed on emergency basis to manage such incidents is too high to ignore. Moreover, there is also the related risk of malpractice litigation given the fact that these incidents are preventable and increasing awareness among people. This article attempts to review potential risks and complications of ingestion/aspiration episodes based on relevant literature and describe the type of appliances and their parts most likely to cause problems. Certain recommendations based on best available evidence to minimize the incidence of such events are proposed, and strategies to aid the clinician in the event of such an emergency are also formulated.

Abstract
THE OBJECTIVE The aim of the study was evaluation of metal ions (nickel and chromium) released from orthodontic appliances in cleft lip and palate patients and the usefulness of non-invasive matrices (saliva and hair). MATERIALS AND METHODS The material studied consisted of 100 individuals, including 59 females and 41 males of 5 to 16 years of age, which were divided into 3 groups: experimental-patients with cleft lip and palate (36 individuals, the average treatment time 5.74 years); control group-patients without cleft lip and palate, during orthodontic treatment (32 individuals, the average treatment time 1.78 years) and the control group patients without cleft lip and palate, without any orthodontic appliances (32 individuals). Samples (saliva, hair) were collected and subjects underwent a survey by questionnaire. Multi-elemental analyses of the composition of non-invasive matrices was conducted in an accredited laboratory by inductively coupled plasma spectrometry technique ICP-OES. The results were reported as mean contents of particular elements (Cd, Cr, Cu, Fe, Mn, Mo, Ni, Si) in hair and in saliva. RESULTS The concentration of Cr, Ni, Fe and Cu ions in saliva of cleft lip and palate patients were several times higher as compared with not treated orthodontically control groups and higher than in the group with orthodontic appliances. Among the assessed matrices, hair of cleft lip and palate patients seem to be not a meaningful biomarker. CONCLUSION It was found that orthodontic appliances used in long-term treatment of cleft lip and palate patients do not release toxic levels of Cr and Ni ions.

Abstract
OBJECTIVES Although inhalation or ingestion of orthodontic appliances can lead to serious medical problems, the real incidence of these complications is anecdotal. This study had two aims: (1) to define the frequency of accidental inhalation/ingestion of orthodontic objects in Finland and (2) to analyze their further management. MATERIALS AND METHODS An electronic, semi-structured questionnaire was sent to all members of the Orthodontic Section of Apollonia, the Finnish Dental Society (n=251) and the Finnish Federation of Dental Hygienists (n=437). After one reminder, 55.8% of dentists and 34.8% of dental hygienists responded. RESULTS In total, 20.0% of the dentists and 6.9% of the dental hygienists reported having one patient who had ingested or inhaled an orthodontic object. The percentages for two or more cases were 18.6% and 6.9%, respectively. According to dentists' answers, the procedures following these complications were (1) observation for 2-14 days (n=27), (2) radiologic evaluation (n=14), (3) medical emergency (n=6) and (4) dietary instruction (n=4). Dental hygienists reported (1) observation (n=9), (2) dietary instruction (n=3) and (3) medical emergency (n=1). None of the cases had been life-threatening. CONCLUSIONS Although the risk of inhalation or ingestion of orthodontic objects is small and the consequences rarely serious, it should be taken into consideration. Prospective patients should be informed of this possibility.

Abstract
Whilst transient effects of orthodontic appliances on the oral mucosa are well recognized, chronic lesions, persisting post therapy are unusual. We describe a persistent lingual mucosal defect related to a transpalatal arch (TPA) in a healthy 19-year-old female. The asymptomatic lesion is presently being monitored, however, surgical revision in the future may be requested by the patient if the area fails to remodel. Clinical Relevance: Soft tissue trauma to the tongue by anchorage reinforcing appliances may result in long-term effects that could require surgical management.

Abstract
Although nickel and chromium are known as allergen and cytotoxic orthodontic metals, very few and controversial studies have assessed the effect of orthodontic treatment on their systemic levels reflected by their best biomarker of exposure, hair. This prospective preliminary study was conducted to evaluate hair nickel and chromium levels in fixed orthodontic patients. Scalp hair nickel/chromium concentrations of 12 female and 12 male fixed orthodontic patients were measured before treatment and 6 months later, using atomic absorption spectrophotometry. The effects of treatment, gender, and age on hair ions were analyzed statistically (α = 0.05). The patients' mean age was 18.38 ± 3.98 years. The mean nickel levels were 0.1380 ± 0.0570 and 0.6715 ± 0.1785 μg/g dry hair mass, respectively, in the baseline and sixth month of treatment. Chromium concentrations were 0.1455 ± 0.0769 and 0.1683 ± 0.0707 μg/g dry hair mass, respectively. After 6 months, nickel increased for 387 % (paired t test P = 0.0000) and chromium increased for 16 % (P = 0.0002). No significant correlations were observed between any ion levels with age or gender (Spearman P > 0.2). Within the limitations of this preliminary study, it seems that 6 months of fixed orthodontic treatment might increase levels of hair nickel and chromium. Future larger studies are necessary to validate these results.

Abstract
Fixed appliances are commonly used in managing early orthodontic problems. Despite their widespread use, they have the potential to impinge on the soft tissues, interfere with the eruption of adjacent teeth and become dislodged or broken. These two case reports present the poor outcomes of fixed appliance treatments if the patient fails to attend follow-up appointments. A successful outcome of treatment with fixed appliances depends upon proper patient selection and the communication skills of the dentist to help patients/parents understand the importance of regular checkups.

Abstract
Successful nonsurgical management of severe postorthodontic gingival enlargement and erythema in a 24-year-old male is presented. The patient received an intensive cause-related periodontal therapy, consisting of oral hygiene instruction, scaling and root planing, and weekly recall visits. At week five, complete resolution of the lesions was achieved. By targeting the primary etiologic factor, i.e., plaque, periodontal health was restored without needing surgical intervention. Reducing the bacterial load will give the biologic natural healing capacity of the body the opportunity to stabilize the periodontal condition and, thus, should be considered as the first line of intervention before a surgical approach is taken.

Abstract
OBJECTIVE The effect of orange juice and Coca Cola(®) on the release of metal ions from fixed orthodontic appliances. MATERIALS AND METHODS A continuous flow system designed for in vitro testing of orthodontic appliances was used. Orange juice/Coca Cola(®) was flowing through the system alternately with artificial saliva for 5.5 and 18.5h, respectively. The collected samples underwent a multielemental ICP-OES analysis in order to determine the metal ions release pattern in time. RESULTS The total mass of ions released from the appliance into orange juice and Coca Cola(®) (respectively) during the experiment was calculated (μg): Ni (15.33; 37.75), Cr (3.604; 1.052), Fe (48.42; ≥ 156.1), Cu (57.87, 32.91), Mn (9.164; 41.16), Mo (9.999; 30.12), and Cd (0.5967; 2.173). CONCLUSIONS It was found that orange juice did not intensify the release of metal ions from orthodontic appliances, whereas Coca Cola(®) caused increased release of Ni ions.

Abstract
OBJECTIVE Orthodontists use various biomaterials such as molar bands, brackets, archwires, transpalatal archwires, facial masks and other auxiliary devices. One of the essential properties of these materials should be the biocompatibility. The aim of this study was to evaluate the biocompatibility of some orthodontic biomaterials like stainless steel archwires, brackets and NiTi (nickel-titanium alloy) coil springs. MATERIALS AND METHODS The studies were performed in vitro using human fibroblasts cultures on which the orthodontic materials were applied. The positive control was the copper amalgam. Readings of the cell reactions were performed at three and six days. RESULTS It was observed that the materials used in the study cause cell alterations of variable intensity. The metallic brackets represent an important cell stress factor causing shape changes. For the metallic brackets, a preferential tropism for different areas of the bracket was also obvious. We observed a preferential tropism for the areas between the NiTi coil spring spirals. For the stainless steel archwires, we observed at six days a decay of cell density and also a higher amount of cells near the archwire areas on which bends were performed. CONCLUSIONS All biomaterials analyzed in our study cause cellular changes of varying intensity without necessarily showing a cytotoxic character.

Abstract
This study examined complications leading to, or possibly leading to, treatment failure, related to the use of the orthodontic bone anchor (OBA). The OBA is a potential means of providing absolute anchorage and consists of a base-plate fixed with mono-cortical screws, a neck piercing the soft tissues, and a coronal part with conventional orthodontic hooks, tubes or slots. The investigation took the form of a single centre prospective registry at a supra-regional teaching hospital. Eighteen patients (average age 21 years) had one to four OBAs placed between January 2000 and February 2002. Altogether 35 OBAs were placed. Follow-up took place until April 2004. Reasons for placing the OBAs were noted together with any associated complications during the follow-up period. Twenty-three OBAs have been removed so far, four prematurely (one of them before it was taken into use, due to a change of treatment plan enforced by loss of the contralateral OBA). Nineteen were removed as planned after completion of the intended tooth movements. Common (but minor) complications included granulations, acute gingivitis and gingival recession. Light mobility of the OBA was also noted in some cases, but without clinical repercussions. The OBA can be loaded directly, at the level of the orthodontic archwire or more occlusally. It can be placed at any site at the circumference of the jaws, given good quality and thickness of the bony wall. Conventional biomechanical techniques can be applied. However, the failure rate (premature loss of OBA) of 8.6% is considered high, and has necessitated changes in the hardware and protocol.

Abstract
With improvements in bonding techniques, bracket base design and bond strengths, molar tubes are becoming more popular in orthodontics. Molar tubes make an attractive alternative to conventional banding due to a reduction in clinical bonding time and ease of placement on partially erupted teeth. The use of molar tubes negates the need for orthodontic separation and subsequent cementation of bands, and offers improved periodontal health. Their use on terminal molars, however, should be limited to non-orthognathic cases. This paper presents two cases of peri-operative second molar tube failure during orthognathic surgery. They are presented in the hope that it will highlight the importance of banding the distal terminal molar in orthognathic cases to prevent loss of molar tubes and peri-operative contamination of the surgical wound site.

Abstract
OBJECTIVE To compare and measure the changes in size of post-orthodontic demineralized white lesion enamel lesions treated with a low fluoride (50 ppm) versus a non-fluoride mouthrinse/toothpaste regime. STUDY DESIGN An experimental double-blind prospective randomized clinical controlled trial. SETTING A university dental school orthodontic clinic (Sheffield, UK). PARTICIPANTS Twenty-six patients identified as having post-orthodontic demineralized white lesions on removal of their fixed appliance. METHOD AND INTERVENTIONS: The participants were randomly and blindly assigned to either a low fluoride mouthrinse/toothpaste treatment regime or an inactive control. Computerized image analysis of calibrated photographic images taken under polarized light were used to measure the lesions. OUTCOME MEASURES Lesion size and proportion (DWL%t) and percentage reduction (ADPR) at debond, and at 12 and 26 weeks later. RESULTS Five participants dropped out of the study, 12 had the low fluoride regime and 9 did not. As a percentage of the total labial tooth area (DWL%t) the mean size of the lesions at debond was 8.1% (SD 3.7). After 12 weeks the mean size of lesion had reduced to 4.6% (SD 2.6), which was a significant reduction (p=0.03). After 26 weeks the mean size was 3.5% (SD 2.1), which was a very significant reduction (p<0.003). This confirmed statistically that post-orthodontic demineralized white lesions do reduce in size with time reflecting remineralization or other enamel surface changes. Intervention using a test low fluoride mouthrinse/toothpaste combination at 26 weeks showed an average difference percentage reduction (ADPR) of 54.3% (Upper 95% CI=62.08, Lower 95% CI=46.44%) compared with a non-active control combination, which showed an ADPR of 66.1% (Upper 95% CI=77.74, Lower 95% CI=54.51%). This failed to show any differences or therapeutic affect. CONCLUSIONS Post-orthodontic demineralized white lesions reduced in size during the 6 months following treatment by approximately half the original size. There was no clinical advantage in using the low fluoride formulation of mouthrinse/toothpaste in this study.
