Backgrond: Until now, there have been many studies on the postoperative stability of orthognathic patients treated with traditional fixed orthodontic appliances. Recently, the use of clear aligners as orthodontic appliances has increased in orthodontic treatment for aesthetic and patient convenience. The aim of this preliminary study was to investigate the stability and characteristics of patients undergoing orthognathic surgery using clear aligners. Patients and Methods: This study was performed on patients who underwent orthognathic surgery by one surgeon at Pusan National University Dental Hospital from April 2017 to August 2021. A comparative study was conducted on five patients treated with clear aligners during orthodontic treatment and ten patients treated with traditional fixed appliances as a control group. Postoperative skeletal changes and recurrence were evaluated by cone beam computed tomography and lateral cephalometric radiographs taken two days postoperatively and six months postoperatively. Several measurement variables were used to confirm the presence or absence of recurrence, preoperative and postoperative orthodontic treatment period, and the number of extracted teeth. Results: Postoperative stability for six months after surgery was not significantly different between the clear aligner group and the traditional fixed appliance group. The preoperative orthodontic treatment period was also shorter in the clear aligner group, and the number of extracted premolar teeth and impacted teeth were also fewer in the clear aligner group, but there was no significant difference. Conclusions: Orthodontic treatment using clear aligners continues to develop, and it is believed that there is no limit to what can be accomplished during orthodontic surgery accompanied by clear aligners.

Good oral hygiene is an important factor in oral and general health, especially in orthodontic patients, because fixed appliances might impede effective oral hygiene and thus increase the risks of tooth decay, periodontal disease and general health complications. This study investigated the impact of fixed orthodontic appliances on the distribution of dental biofilm in teenagers. Supragingival plaque was assessed at T0, T1 and T2. The distribution of the biofilm was analyzed. Approximal Plaque Index (API) and Bonded Bracket Index (BBI) were used to measure the presence of dental plaque. After insertion of the fixed appliance, the dental plaque indices values in the orthodontically treated group were significantly higher (p < 0.05) than in the control group. Fixed orthodontic appliances caused significant changes in the distribution of the biofilm. This was characterized by the change of location of the dental plaque. In the orthodontic group, we observed an increase in the amount of the supragingival plaque on the vestibular surface of the teeth.

Objectives: This study was aimed to assess salivary sodium and potassium concentrations in patients with fixed orthodontic appliances. Methods: In this case-control study, saliva samples (5 cc) were collected from 13 patients with fixed orthodontic appliances before, and 1 week, 1 month and 3 months after the beginning of the orthodontic treatment using the spitting method. Saliva samples were also collected from 10 healthy individuals as controls. The saliva samples were centrifuged at 3000 rpm for 10 minutes and the salivary sodium and potassium concentrations were measured by spectrophotometry. Data were analyzed using independent and paired t-tests. P-value < 0.05 was considered as significant. Results: The salivary sodium and potassium concentrations were almost the same in both groups at baseline (P > 0.05). A significant reduction in sodium and an increase in potassium levels were noted in the case group at 1 week compared with baseline (P < 0.001). At 1 week, the potassium concentration was significantly higher and the sodium concentration was significantly lower in the case group (P < 0.01). The salivary sodium significantly increased while the salivary potassium significantly decreased at 1 month compared with 1 week (P < 0.001). The differences with the control group were also significant (P < 0.05). No significant differences were noted between the two groups at 3 months (P > 0.05). Conclusions: Time has a significant effect on the release profile of sodium and potassium ions from orthodontic appliances. The salivary sodium and potassium concentrations returned to their normal pretreatment values within 3 months after the start of fixed orthodontic treatment.

ABSTRACT Objective: The aim of this retrospective study was to evaluate the relationship between orthodontic treatment and gingival health. Materials and Methods: A total of 251 patients among whom 177 were girls and 74 were boys, recruited from the records pool of the Department of Orthodontics, Faculty of Dentistry, University of Gazi, were included in the study. Patients’ treatments have been completed by postgraduate students during the period between 2006 and 2012. Patients’ folders were analyzed according to their age, treatment time, and the type of orthodontic treatment. Intra-oral photographs were analyzed, and the presence or absence of visible plaque, visible inflammation, and gingival recession were recorded, and incisor inclinations analyzed on lateral cephalometric films, before and after orthodontic treatment. Results: No statistically significant difference was found in patients treated with functional appliances before and after treatment. In patients treated with fixed orthodontic appliances, visible plaque, visible inflammation, and gingival recession showed significant increases after treatment, gingival biotype did not show any significant difference. Positive correlation was found between lower incisor position and gingival recession in patients treated with fixed appliance and extraction. And also cuspids were the teeth with the highest prevalence of gingival recession. Conclusion: Considering the relationship between orthodontic treatment and gingival health, cooperation among patients, orthodontists, and periodontists is important.

Fixed orthodontic treatment has been compromised at many levels during the pandemic period, as clinics underwent a prolonged lockdown and patients could not be treated regularly. With the end of the pandemic nowhere in sight, may be it is time to put newer tools, such as clear aligner therapy, for better use. Fixed orthodontic appliances by nature are not always self-limiting, which, if left unmonitored over a long period may cause undesirable side effects, pain, and discomfort. The undesired tooth movements that may occur with arch wire-guided mechanics in addition to problems with cut wires or removed brackets may be minimized with the use of aligners. While the benefits of using aligners are for all to see, they do require extensive planning and careful evaluation of the progress. This article reviews the advantages of using aligners during the pandemic period and how it can be beneficial in helping orthodontists resume their practice.

Background: Fixed orthodontic appliances, such as Edgewise and Straightwire techniques, can increase the amount of plaque retention containing Streptococcus mutans (S. mutans), which can lead to white spot lesions. Purpose: The aim of this study is to analyse the correlation of fixed orthodontic treatment with Edgewise and Straightwire techniques on the incidence of white spot lesions and accumulation of S. mutans. Methods: The samples consisted of three groups: control group (n=8), Edgewise technique group, and Straightwire technique group. We observed the samples at the sixth month and eighth month of the treatment, after the installation of the fixed orthodontic appliances. The observation of white spot lesions with caries detector was applied in all regions. Bacterial swabs were acquired in the lateral incisor region, then a bacterial culture procedure was carried out on selective media of S. mutans, and then a bacterial count was performed. The data was analysed using two-way ANOVA, the post-hoc least square differences test, and the Pearson’s correlation test. Results: The number of white spot lesions in the Edgewise group was higher than in the Straightwire group in the sixth and eighth month of treatment with insignificant difference (p>0.05). The number of S. mutans bacteria increased in all groups, but there were no significant differences (p>0.05). There was no significant relationship between the number of white spot lesions with the accumulation of S. mutans between groups (p>0.05). Conclusion: The Edgewise and Straightwire techniques increase the incidence of white spot lesions but accumulation of S. mutans with the incidence of white spot lesions has no relationship.

ABSTRACT Aim The study aimed to assess the impact of mouthwashes on antibacterial activity of individuals with fixed orthodontic appliances. Materials and methods A total of 60 individuals were considered in the study. Sixty (20 each group) nonextraction class I individuals were randomly divided into experimental and control groups. Group I: Experimental group [chlorhexidine (CHX) mouthwash], group II: Experimental group (neem mouthwash), group III: Control group (distilled water). All the clinical examinations were done at baseline and 30th day respectively, after the start of orthodontic treatment. The mean differences between the different experimental groups were calculated using one-way analysis of variance (ANOVA) test. Results There was no statistical significance at baseline mean plaque index (PI), gingival index (GI) scores, and Streptococcus mutans (SM) colony count between groups. The PI and GI scores among CHX and neem mouthwash groups (p = 0.002, p = 0.032 respectively) were significantly reduced after intervention and also the SM colonies count was reduced in CHX and neem mouthwash groups and there was significant difference between the groups. Conclusion As both mouthwashes showed significant effectiveness on antibacterial activity in individuals with fixed orthodontic appliances, neem mouthwash can be used as an alternative to CHX. Clinical significance It is better to have a sound knowledge regarding the use of mouthwash in long term as fixed orthodontics are associated with accumulation of SM, enamel demineralization, and an increased number of carious lesions, predominantly in sites adjacent to bracket.

ABSTRACT Objectives To identify microorganisms isolated from patients wearing fixed orthodontic appliances and to evaluate the resistance of isolated bacterial strains to different antimicrobials. Materials and Methods Seventeen healthy patients wearing a fixed orthodontic appliance (group 1) and six nonwearers (group 2, control group) were evaluated. The biofilm that formed around the orthodontic brackets was collected, and the samples were then plated in a chromogenic medium (chromIDT, bioMérieux). Colony-forming units (CFUs) were isolated and inoculated in blood-agar medium. Automated biochemical tests (VITEK 2, bioMérieux) were carried out to identify the genus and species of the microorganisms and the resistance provided by 43 drugs (37 antibacterial and 6 antifungal). Results The most prevalent microbial genera identified in group 1 were Streptococcus (24.0%), Staphylococcus (20.0%), Enterobacter (12.0%), Geobacillus (12.0%), and Candida (12.0%), and the most frequent species were Enterobacter cloacae complex (13.6%) and Staphylococcus hominis (13.6%). In group 2, the most prevalent genera were Streptococcus (57.1%), Staphylococcus (14.2%), Sphingomonas (14.2%), and Enterobacter (14.2%). With regard to antimicrobial resistance, 14 of 19 (74%) isolated bacterial strains were found to be resistant to at least 1 of the tested antimicrobials. Conclusions The findings of the present study suggest that patients undergoing orthodontic treatment with fixed appliances have a more complex biofilm with a higher level of bacterial resistance.

Orthodontic treatment may affect the equilibrium of oral microbiota which plays a major role in aetiology of periodontal disease. This prospective clinical study aimed to assess the periodontal health and microbiological profile of healthy (Group 1) and stabilised periodontal (Group 2) patients throughout three months of orthodontic treatment. Upper and lower fixed orthodontic appliances were bonded. Periodontal health was assessed using plaque score (PS), bleeding on probing (BOP) and pocket depth (PD). 29 sites were taken for subgingival plaque sampling. Plaque samples were inoculated on Trypticase Soy Blood Agar (TSBA) and Trypticase Soy Bacitracin Vancomycin (TSBV) agar for assessment of aerobe, anaerobe, black pigmented bacteria (BPB) and Aggregatibacter actinomycetemcomitans. All the measurements were taken before bonding (T0), 1 week (T1), 1 month (T2) and 3 months post-bonding (T3). Generally, periodontal health in both groups were almost similar. After 1 week, the number of aerobes was significantly higher in Group 1 (88%) while the anaerobes were significantly higher in Group 2 (45%). A. actinomycetemcomitans was higher in Group 1 at T0 and T1 but was significantly higher in Group 2 at T3. BPB was minimal at all time with no significant difference. Thus, during the first 3-month of orthodontic treatment, there were significant changes in the number of aerobes-anaerobes in both healthy and stabilised periodontal patients. Pathogenic bacteria would increase during early treatment of orthodontics.

Background/Aim. Orthodontic treatment enables the establishment of functional occlusion and improvement of oral health, however, it increases the risk of periodontal disease development. The aim of this paper was to examine the efficiency of the applied programme for the prevention of gingivitis in children undergoing the fixed orthodontic appliance therapy and to determine the most efficient devices and techniques for maintaining oral hygiene during orthodontic treatment. Methods. The study included 80 patients of both genders - 60 patients comprised the experimental group and 20 patients comprised the control group. All of them were patients of the Clinic for Orthodontics at the School of Dentistry in Belgrade, aged between 13 and 18. The Silness-L?e Plaque Index (PI) was utilised for the assessment of oral hygiene quality and Silness-L?e Gingival Index (GI) and M?hlemann Papilla Bleeding Index (PBI) were utilised for the assessment of gingival state. Checkups were conducted as a single-blind study at the beginning and after the first, the third and the sixth month of the preventive and prophylactic programme. Results. During the observed period, a statistically significant change in PI, GI and PBI values was noticed (p < 0.005), as well as the difference in the dynamics of value changes during the periods between the observed groups. Conclusion. The preventive programme, applied to children undergoing the fixed orthodontic appliance therapy, had a positive effect both on oral hygiene quality and gingival state. The values of the examined parameters of the patients from the experimental group were significantly lower in comparison with those of the patients from the control group. The most efficient combination of devices for oral hygiene during orthodontic treatment was: a Curaprox CP5460 toothbrush, CD Ortho 60 orthodontic toothbrush and Curaprox CPS 14 interdental brush.

Introduction. During orthodontic treatment, there is increased risk of periodontal disease and caries. Therefore these patients must be trained to maintain proper oral hygiene to minimize risks. The aim of this study was to examine the effects of oral hygiene training with different devices as well as a motivation and remotivation in oral hygiene using brochures, verbal methods and tablets for plaque identification. Material and Methods. The study included 80 subjects, both genders, divided in control (20) and experimental groups (60). All examinees in the experimental groups used toothbrush Curaprox CP5460 for oral hygiene. Subjects in experimental group 1 used mouthwash Curasept ADS 205, in the experimental group 2 orthodontic toothbrush CD Ortho 60 and proximal toothbrush Curaprox CPS14 while subjects in experimental group 3 used proximal toothbrush Curaprox CPS14 and mouthwash Curasept ADS 205. All participants were given tablets erythrosine and brochure in which was explained and illustrated the use of the aforementioned means for oral hygiene. Control check ups were conducted at the beginning, after the first, third and sixth month of the preventive program. Results. The values of the examined parameters, plaque index (PI), gingival index (GI) and gingival bleeding index (GBI), in experimental groups were significantly lower compared to control group (p<0.05). Conclusion. Motivation, compliance and implementation of all preventive procedures proposed by this program, as well as regular controls, contributed in maintaining gingival health during orthodontic treatment.
