RESUMEN
INTRODUCTION: The aim was to elucidate the magnitude of alterations in systemic blood counts in healthy patients during the first 14 days after fixed orthodontic appliance placement. METHODS: This prospective cohort study consecutively included 35 White Caucasian patients starting orthodontic treatment with fixed appliances. The mean age was 24.48 ± 6.68 years. All patients were physically and periodontally healthy. Blood samples were collected at 3 time points: (1) baseline (exactly before the placement of appliances), (2) 5 days after bonding, and (3) 14 days after baseline. Whole blood and erythrocyte sedimentation rates were analyzed in automated hematology and erythrocyte sedimentation rate analyzer. Serum high-sensitivity C-reactive protein levels were measured by the nephelometric method. Standardized sample handling and patient preparation procedures were adopted to reduce preanalytical variability. RESULTS: A total of 105 samples were analyzed. All clinical and orthodontic procedures were performed without complications or side effects during the study period. All laboratory procedures were performed per protocol. Significantly lower white blood cell counts were detected 5 days after bracket bonding, compared with baseline (P <0.05). Hemoglobin levels were lower at 14 days than baseline (P <0.05). No other significant shifts or alteration patterns were observed over time. CONCLUSIONS: Orthodontic fixed appliances led to a limited and transient change in white blood cell counts and hemoglobin levels during the first days after bracket placement. The fluctuation of high-sensitivity C-reactive protein levels was not significant, demonstrating a lack of association between systemic inflammation and orthodontic treatment.

OBJECTIVES: Assess knowledge, attitudes and practices of paediatric dentists towards dentomaxillofacial imaging and correlate findings with practitioner and practice-specific characteristics. METHODS: An online questionnaire was sent to all paediatric dentists who attended a scientific seminar organized by the European Academy of Paediatric Dentistry (EAPD) regarding dental radiology. Data regarding available equipment, number, type and reason for performing radiographs, frequency and reasoning for retakes were collected. Data analysis was performed according to practitioner- and practice-specific characteristics and factors directly associated with the type and frequency of radiographs taken, and reason and frequency of repeats were determined. Significant differences were tested using Chi-square and Fisher's exact test. Statistical significance was set at p < 0.05. RESULTS: More than half of the participants (58%) reported having digital radiographic equipment and almost 1/4 (23%) conventional. A panoramic equipment was available in 39% working places and a CBCT scanner in 41%. Two thirds of the participants reported taking up to 10 intra-oral radiographs per week, mainly for trauma (75%) and caries diagnosis (47%). Extra-oral radiographs were prescribed to monitor development (75%) and for orthodontic evaluation, (63%) with a frequency of less than 5 weekly (45%). Participants reported that they repeat radiographs in a frequency of < 5 per week (70%) mainly due to patient's movement (55%). CONCLUSIONS: The majority of paediatric dentists within Europe use digital imaging equipment for both intra- and extra-oral radiographs. Nevertheless, great variation in practices exists and, therefore, continuous education in oral imaging is crucial to maintain high quality standards for the radiographic examination of patients.

OBJECTIVES: Objective of this trial was to assess the masking results in initial caries lesions (ICL) that were resin infiltrated during fixed orthodontic treatment in comparison to contralateral teeth that were fluoridated only. TRIAL DESIGN: A randomized, controlled, split-mouth trial. METHODS: Adolescent patients (age range: 12-18 years) with fixed orthodontic appliances who had developed ICL [ICDAS 1 or 2 (International Caries Detection and Assessment System)] during orthodontic treatment were consecutively recruited and randomly assigned to either resin infiltration (Icon) with up to 3 etching procedures (Inf) or to a fluoride varnish (Tiefenfluorid) (FV). Both interventions were performed according to the manufacturer's recommendations. Outcome assessors were blinded to the applied intervention. Primary and secondary outcomes included the evaluation of the appearance of the ICL before (T0) and 1 week after (T1) treatment by digital photographs (ΔE), laser fluorescence readings (DD), and ICDAS scores. BLINDING: Due to the treatment nature neither the operators nor the patients could be blinded. However, outcome assessors and the statistician were blinded. RESULTS: Fifteen patients (9 female) with 60 ICL were included (mean age: 14.6 years). At baseline FV and Inf did not differ significantly in ΔE (median ΔE0,T (25th/75th percentiles):10.7(9.1/20.9): ΔE0,I:13.4(10.3/18.5); P = 0.469), DD (P = 0.867) and ICDAS (P = 0.521). One-week after treatment (T1) ΔE values (P < 0.001), DD values (P < 0.001), and ICDAS scores (P = 0.014) for Inf were significantly reduced, whereas ΔE values (P = 0.125) and ICDAS scores (P = 0.073) for FV remained unchanged. LIMITATION: Natural remineralizing in the standard interventional control group cannot be observed yet, since up to 6 months are needed to naturally remineralize ICL. CONCLUSIONS: Based on our short-term data, resin infiltration effectively masked ICL during treatment with fixed orthodontic appliances. Fluoridation was not able to immediately improve the visual appearance of ICL. Further longer-term assessment should focus not only on the aesthetic outcome, but also on the caries inhibitory effect of resin infiltration during treatment with fixed orthodontic appliances. TRIAL REGISTRATION: German Clinical Trials Register (DRKS-ID: DRKS00011797).

PURPOSE: To summarise the available data on the effects of chlorhexidine (CHX) mouthwash in treating gingivitis during treatment with fixed orthodontic appliances. MATERIALS AND METHODS: Multiple electronic databases were searched up to December 7th, 2021. Only randomised controlled trials (RCTs) were eligible for inclusion. The quality of the included RCTs was assessed with the Cochrane risk of bias tool for randomised trials (RoB 2.0). After data extraction and risk of bias assessment, differences were recorded in several oral hygiene indices in time and mean percentage change in those indices using different antimicrobial solutions. RESULTS: Fourteen studies were deemed eligible for inclusion, reporting on a total of 602 patients with an age range of 11-35 years. The experimental solution was a 0.06%, 0.12%, or 0.2% CHX mouthwash with the control either a placebo mouthwash or a selection from a variety of mouthwashes. Treatment duration varied from 1 day to almost 5 months and the follow-up period varied from 1 min to 5 months. Chlorhexidine mouthrinses led to reduced plaque accumulation and gingival inflammation during orthodontic treatment, while at the same time, some of the control group mouthrinses were deemed equally effective. No statistically significant difference was detected in the meta-analysis between CHX and mouthwashes with propolis/probiotics/herbs in terms of the gingival index at 3 to 4 weeks (mean difference 0.07, 95% CI: -0.18, 0.31, p = 0.59). CONCLUSION: Chlorhexidine mouthwash in orthodontic patients successfully controls gingival inflammation and bleeding when compared to untreated controls, but is equally effective as other mouthrinses where various oral health indices are concerned.

OBJECTIVES: The aim of this systematic review is to summarize the available data on the effects of organic unprocessed products in treating gingivitis during treatment with fixed orthodontic appliances. MATERIALS AND METHODS: Multiple electronic databases were searched up to October 1, 2020. Randomized controlled trials (RCTs), controlled clinical trials, cohort studies of prospective and retrospective design, and cross-sectional studies reporting on natural products for controlling gingivitis in orthodontic patients were eligible for inclusion. The quality of the included RCTs was assessed per the revised Cochrane risk of bias tool for randomized trials (RoB 2.0). RESULTS: Three RCTs were finally eligible for inclusion, yielding a total of 135 patients with an age range of 12-40 years. Organic products used were Aloe vera mouth rinse, ingestion of honey and chamomile mouthwash. Treatment follow-up period varied from 30 min to 15 days. The results indicated that the use of the aforementioned organic products significantly reduced plaque and gingival bleeding levels as early as treatment started. The reduction in biofilm accumulation and gingival bleeding was significant throughout the studies' follow-up. CONCLUSIONS: Owing to their antimicrobial and anti-inflammatory properties, nonpharmacological formulations successfully controlled gingival inflammation and plaque indices in orthodontic patients.
