The plaque-retentive properties of fixed orthodontic appliances result in a severe challenge on surfaces generally not susceptible to caries. Lesions may develop within a month in the absence of fluoride, and clinical studies have shown that from 50 to 75% of orthodontic patients develop decalcifications on labial surfaces during treatment. Fluoride mouthrinses reduce the occurrence, although compliance is often poor. Orthodontic bonding agents and cements releasing fluoride, which reduce the need for cooperation, have been introduced. Few clinical studies have been done to prove the cariostatic properties of fluoride-releasing materials in orthodontics. In short-term caries model studies, glass ionomers and a glass filler containing light-cured adhesive that releases relatively large amounts of fluoride have shown cariostatic properties. However, during severe challenges such as occur with orthodontic appliances, fluoride alone has limited cariostatic properties. The combination of fluoride with antimicrobial agents, and the use of acidic fluoride solutions depositing acid-resistant coatings of calcium fluoride and titanium have shown to give better clinical effects than fluoride alone during extreme conditions. Fluoride-releasing materials may therefore be considered as useful supplements to these procedures.

Abstract Objective: To determine antibacterial activity of chewing mastic gum against the salivary levels of Streptococcus mutans, the total number of viable bacteria, and lactobacilli in patients undergoing therapy with fixed orthodontic appliances. Materials and Methods: In this study, the levels of S mutans, lactobacilli, and total cultivated bacteria were measured before and after chewing mastic gum. The antibacterial effects of chewing mastic gum against these microorganisms in saliva were compared with a placebo gum. The counts for orthodontically treated patients were evaluated before chewing gum; just after chewing gum; and after 45, 75, 105, and 135 minutes. Saliva samples taken from the patients were inoculated onto trypticase-yeast-cystine-bacitracin agar for mutans streptococci and onto Rogosa agar for lactobacilli. The agar plates were incubated for 48 hours anaerobically at 37°C. The total number of viable bacteria was then counted. Results: Just after chewing the mastic gum for 15 minutes, a significant decrease of total bacteria and S mutans was observed (P < .001). The reduction in lactobacilli was not significant at later first stage (P > .05). However, at the end of 135 minutes, there were significantly fewer S mutans (P < .001), total viable bacteria (P < .001), and lactobacilli (P < .001) in the oral cavity after chewing mastic gum than after chewing paraffin (P < .001). The results show that chewing mastic gum decreased the total viable bacteria, S mutans, and lactobacilli in saliva in orthodontically treated patients with fixed appliances. Conclusion: Chewing mastic gum might be useful in preventing caries lesions.

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.

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.

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.

Abstract Objective: To determine the absolute and relative antibacterial activity of octenidine dihydrochloride (OCT) against total and cariogenic bacteria in saliva samples of patients with fixed orthodontic appliances during 5 days of usage. Materials and Methods: The study group consisted of 5 male and 13 female subjects who were selected from patients in the Clinic of Orthodontics. Each patient was given physiologic saline (PS), chlorhexidine gluconate (CHX), polyvinylpyrrolidone-iodine complex (PVP-I), and OCT every morning for 5 days, each separated by a 2-week interval. Total and cariogenic bacteria in saliva samples of orthodontically treated patients with fixed appliances were collected during 5 days of usage. Unstimulated saliva was collected as a baseline sample. Saliva samples were collected at 15 minutes, and on the second, third, and fifth day after rinsing the mouth with any of the solutions for 30 seconds, and bacterial counts were detected. Results: OCT showed an ultimate reduction of total viable oral bacteria, Lactobacillus species, and Streptococcus mutans in vivo. OCT also had a significantly greater inhibitory effect than 0.2% CHX and 7.5% PVP-I, from the beginning of the study until the fifth day after the orthodontic appliances were bonded (P < .1). Conclusions: OCT compared favorably with respect to CHX and PVP-I complex in orthodontically treated patients with fixed appliances (P ≤ .1).

Fixed orthodontic appliances causes plaque accumulation, which leads to the formation of dental caries and gingivitis. Therefore, concise oral hygiene instructions (OHI) is necessary to avoid the occurrence of these diseases. Massive Open Online Course (MOOC) ensures interactive learning to improve knowledge retention. MOOC transfers the responsibility of learning OHI to the patients with remote guidance from the clinician, thus reduces clinical time. This research aimed to develop the MOOC learning content on OHI in orthodontic practice. The secondary aim was to assess the overall analytics data among learners enrolled for the completion rate and time taken to complete the MOOC. The ADDIE principles which were, "Analyse, Design, Develop, Implement and Evaluate", were used to develop the MOOC. The contents were based on a published pamphlet of OHI from the Ministry of Health, Malaysia. The MOOC was pre-tested, and content was improved based on the feedback from users and experts. The MOOC named “Penjagaan Kebersihan Pendakap Gigi” utilises the Bahasa Melayu language to educate learners regarding oral care with orthodontic appliances. Sixty-two learners joined the MOOC, with 77.4% achieving a high rate of completion of the MOOC learning content. There were forty-six female learners (74.2%), while male learners comprised sixteen (25.8%). The median (interquartile range) time taken to complete MOOC learning content were 31.50 minutes, (13.00 minutes to 55.50 minutes). This shows that MOOC could be an alternative platform to instruct patients on OHI with fixed appliances. MOOC can potentially reduce clinical time to teach OHI to patients.

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.

ABSTRACT Objectives: To assess plaque and gingivitis reduction in orthodontic patients after 4 weeks' use of an oscillating-rotating power brush, irrigator, and mouthrinse. Materials and Methods: This was a randomized, examiner-blind, clinical trial comparing plaque and gingivitis outcomes for an experimental power brush/irrigator/mouthrinse oral hygiene routine vs a dental prophylaxis followed by regular manual brushing (positive control). Fifty-one participants with fixed orthodontic appliances in the upper and lower jaw and a minimum of 15 gingival bleeding sites were randomly assigned to experimental or positive control treatment. Both groups were instructed to use their products at least twice daily. At baseline, week 1, and week 4, plaque was evaluated using digital plaque imaging analysis and a conventional subjective index. Gingival inflammation and bleeding were also measured. Analysis of covariance was used to compare groups. Results: Fifty-one participants (mean age = 13.9 years) were randomized; 50 (25 per group) completed the study. At baseline, group means were not statistically different (P > .1) for gingival inflammation or bleeding. At week 4, the experimental and control groups had a 10.0% to 32.7% and 5.9% to 6.7% reduction vs baseline, respectively, in plaque (across both methods); 12.6% and 8.3% reduction, respectively, in gingival inflammation; and 50.6% and 37.8% reduction, respectively, in bleeding. At week 4, group differences favoring the experimental group were statistically significant (P < .05) for gingival inflammation, gingival bleeding, and plaque (by conventional and digital imaging indexes). Conclusions: Use of a power brush/irrigator/mouthrinse resulted in statistically significantly greater plaque and gingivitis reductions than prophylaxis followed by manual brushing in patients with fixed appliances over 4 weeks.
