The aim of this study was to investigate the effects of Cervitec Plus® on the level of mutans streptococcus (SM) and lactobacillus (LB) colonies and the development of white spot lesions (WSLs) in patients with fixed orthodontic appliances. Informed consent was obtained from 32 volunteers (age 16.5 ± 2.75 years). At baseline, levels of the bacterial colonies were determined in saliva and plaque using a chairside test (CRT Bacteria, Ivoclar-Vivadent, Schaan, Liechtenstein), and the number of WSLs was registered. After placing the fixed appliance, Cervitec Plus® or placebo varnishes (Ivoclar-Vivadent, Schaan, Liechtenstein) were applied monthly around the brackets and tubes, randomly in the right or left (test and placebo) quadrants of the same dental arch. SM and LB colonies in saliva and the SM colonies in plaque were determined on 11–21, 13–23, 15–25, and 16–26 teeth monthly over a 6-month period. At the sixth month, the number of new WSLs was determined. By the end of the study, compared with baseline, the ratio of saliva samples belonging to the low-risk category was significantly higher (p ≤ 0.01) from the 2nd month regarding the SM (76 vs. 52%) and LB (69 vs. 52%); reduction of SM in plaque was significantly greater on the test than placebo sides (6.69 ± 1.71 and 4.45 ± 1.60, respectively; p ≤ 0.01). The mean number of new WSLs was significantly lower in the test (0.06 ± 1.60) than in the placebo quadrants (1.13 ± 1.50, p ≤ 0.01). Conclusion: Monthly use of Cervitec Plus® could result in a significant improvement in oral health of orthodontic patients.

Introduction. The placement of fixed orthodontic appliances may lead to increased plaque accumulation and changes in subgingival microflora. Objective. The aim of this study was to examine the changes in frequency of subgingival microflora that occur after placement and removal of fixed orthodontic appliance using polymerase chain reaction (PCR). Methods. This study included 33 orthodontic patients, who were divided into two groups. Subgingival plaque samples were collected from the right upper incisor (U1) and right upper first molar (U6). In group A, the samples were taken three times: before placement appliance (T1), after one month (T2), and after 3 months (T3). In group B the samples were also taken three times: before appliance removal (T1), after one month (T2), and after three months (T3). PCR method was used to determine the presence of P. gingivalis, A. actinomycetemcomitans, T. forsythia, and P. intermedia. Results. In group A the frequency of P. gingivalis showed statistically significant decrease at U1 (p=0.049) and U6 (p=0.008), from T1 to T2, and at U1 (p=0.048) from T1 to T3. In group B only the frequency of T. forsythia showed a statistically significant decrease, at U6 (T1 vs. T2, p=0.004; T1 vs. T3, p=0.0003). Regarding other analyzed bacteria, changes in the presence were noticed but no statistical significance was found. Conclusion. Placement of fixed appliances may have an impact on subgingival microflora, but in the first months after the placement and removal of the appliance changes were not significant, probably due to good oral hygiene.

ABSTRACT Objective: To compare the plaque removal efficacy of an oscillating-rotating electric toothbrush with an orthodontic brush head versus a sonic toothbrush in adolescent patients with fixed orthodontic appliances. Materials and Methods: This was a randomized, examiner-blind, replicate single-use, two-treatment, four-period, crossover study with a washout period between visits of approximately 24 hours. Forty-four adolescent patients with fixed orthodontic appliances in both arches were randomized based on a computer-generated randomization schedule to one of four toothbrush treatment sequences. The primary outcome was plaque score change from baseline, measured using digital plaque imaging analysis. Results: Baseline plaque levels for both brush treatments were high, covering more than 50% of the tooth area. Effective plaque removal was observed with both brush treatments (P < .001); however, the reduction in plaque with the oscillating-rotating toothbrush was statistically significantly greater (P = .017) compared with the sonic toothbrush. Conclusions: The study provides evidence for more effective plaque-removing efficacy of the oscillating-rotating toothbrush versus the sonic toothbrush among orthodontic patients.

The Impact

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.

ABSTRACT Objectives: To examine possible changes in the levels of salivary antioxidants, C-reactive protein (CRP), cortisol, pH, proteins, and blood in patients treated with fixed orthodontic appliances. Materials and Methods: Salivary samples from 21 orthodontic patients who met specific inclusion criteria were collected before the beginning of orthodontic treatment (T0; baseline), 1 hour after bonding (T1), and 4–6 weeks after bonding (T2). Oxidant-scavenging ability (OSA) was quantified using a luminol-dependent chemiluminescence assay. Cortisol and CRP levels were measured using immunoassay kits. pH levels and presence of proteins and blood in the samples were quantified using strip-based tests. Results: A significant decrease in salivary pH was observed after bonding (P = .013). An increase in oxidant-scavenging abilities during orthodontic treatment was detected, but the change was not statistically significant. Cortisol and CRP levels slightly increased after bonding, but the difference was small without statistical significance. Changes in the presence of proteins and blood were also insignificant. Conclusions: Exposure to fixed orthodontic appliances did not show a significant effect on salivary parameters related to inflammation or stress, with the exception of a significant but transient pH decrease after bonding.

ABSTRACT Objectives:  To clinically evaluate the effectiveness of three orthodontic aligning archwires in relation to tooth alignment speed during the initial alignment stage of treatment. Materials and Methods:  A consecutive sample of 74 patients requiring lower only or upper and lower fixed orthodontic appliances were randomly allocated into three different archwires (0.014-inch superelastic nickel-titanium [NiTi], 0.014-inch thermoelastic NiTi, or 0.014-inch conventional NiTi). Good quality impressions were taken of the lower arch before archwire placement (T0) and at designated serial stages of alignment (every 2 weeks: T2, T4, T6, …, T16). The change in tooth alignment was measured in millimeters from the resultant casts using Little's irregularity index. Demographic and clinical differences among the three groups were compared with the chi-square or analysis of variance (ANOVA) test. The difference in the change of lower anterior tooth alignment over time among the three groups was explored with a Split Plot ANOVA (SPANOVA, or within- and between-groups ANOVA). The Kruskal-Wallis nonparametric test was used when data were not normally distributed. Results:  The SPANOVA and Wilks Lambda Multivariate test confirmed that the wire type had no influence on the rate of change in alignment (P  =  .98). Conclusion:  The three forms of NiTi wires were similar in terms of their alignment efficiency during the initial aligning stage of orthodontic fixed appliance therapy.

"Dental practitioners, sometimes, are facing patient’s requests to overtreatment care, which in many situations is completely unnecessary or even dangerous/ risky/ disproportionate to the patient’s (oral) health state/condition. It can include procedures such as: teeth whitening, removal of amalgam fillings, closing diastema, veneers, dental extractions, root canal treatment, dental implants or fixed orthodontic appliances. It is known that dentistry practice belongs to two different and conflicting worlds, medical and business. In front of such situations, dentists should decide the right way of doing their job: being a medical doctor and treating patients or doing business and executing exactly what patients are asking for. Due to these facts, this presentation aims to: 1) identify the main issues related to this dilemma of dentists and 2) offer a better perspective on realizing dental esthetics treatments without jeopardize the oral health of the patient, but also the dentist’s profession and professional integrity.

Background: Oral hygiene maintenance becomes difficult during fixed orthodontic treatment.Objective: The aim of this study was to assess Gingival Bleeding Index among patients treated with fixed orthodontic appliances in a tertiary level hospital.Metanitil and Methody: This study was conducted on 100 patients treated with fixed orthodontic appliances for more than six months in the OPD of Orthodontics Department at Bangabandhu Sheikh Mujib Medical University, Dhaka from July 2013 to July 2014. All the information related to oral hygiene maintenance like brushing, dental floss use, use of mout hwash during treatment in the OPD were recorded. The Gingival Bleeding Index (GBI) was calculated and recorded. Apart from this, frequency of brushing, type of tooth brush, technique of brushing and inter dental brush were also considered.Result: Over all mean value of GBI was 23.44±17.00. Mean value of GBI was 26.44 ± 15.23 among patients who brushed their teeth once a day but it was decreased gradually as the patients increased frequency of toot hbrush use per day and became 11.55±4.71 among the patients who brushed their teeth thrice a day. Mean value of GBI was 23.46±17.18 who did not use dental floss and 22.85 (12.64) who used dental floss once a day. Mean value of GBI was 25.30±17.73 who used inter dental brush irregularly but 2.75±0.35 who used it thrice a day. Mean value of GBI was25.17±17.69 who did not use mouth wash whereas it reduced to 8.00±0.00 among them who used mouth wash thrice a day.Conclusion: The Gingival Bleeding Index (GBI) is increased in patients treated with fixed orthodontic appliances.KYAMC Journal Vol. 9, No.-3, October 2018, Page 129-132

Abstract Objective: To evaluate changes that occur in the subgingival microbiota after removal of fixed orthodontic appliances using polymerase chain reaction (PCR). Materials and Methods: Thirty orthodontic patients (11 males and 19 females; aged 20 ± 7.3 yr) were included in this study. Subgingival plaque samplings were gathered from the disto-buccal gingival crevice of the left upper central incisors and the left lower central incisors, and from the mesio-buccal gingival crevice of the left upper first molars and the left lower first molars, at two different times: 2 weeks before appliance removal (T1), and 3 months after appliance removal (T2). DNA was extracted from the samples and the 16S rRNA-based PCR detection method was used to determine the prevalence of Actinobacillus actinomycetemcomitans, Tannerella forsythia, Campylobacter rectus, Eikenella corrodens, Porphyromonas gingivalis, Prevotella intermedia, Prevotella nigrescens, and Treponema denticola, which are considered as putative periodontopathogens. Results: The frequency of positive sites at T1 and T2 was 65% and 43.3% for C. rectus, and 53.3% and 30.8% for E. corrodens, respectively. For the other bacteria, the frequency tended to be reduced between times. Conclusion: Periodontopathogens during orthodontic treatment were significantly reduced within 3 months of appliance removal. However, how long it takes to return to the preorthodontic composition of the subgingival microbiota and whether it happens at all remain to be seen.
