Background and Purpose. Fixed orthodontics may be associated with accumulation of Mutans Streptococci (MS), enamel demineralization, and an increased number of carious lesions, predominantly in sites adjacent to brackets. This study was undertaken to assess the effectiveness of Listerine, Oral-B, and Ortho-kin on the accumulation of MS in plaque around orthodontic brackets. Materials and Methods A double-blind randomized cross-over clinical trial on 25 orthodontic patients, classified into 6 groups was done to assess MS in plaque and saliva with the side specific modified Strip-Mutans technique and the plaque (PI) was measured before and after rinsing using 3 types of commercial mouth-rinses. A washout period (3 weeks) was awaited between using each mouth-rinse and the data was analyzed via Wilcoxon and Kruskal Wallis statistical tests. Results. This study of 25 patients, 5 men and 20 women, with an average age of assessed the effectiveness of mouth-rinses on MS. Our results showed that Ortho-kin had a better effect than Oral-B and Listerine (). Ortho-kin also had better effects than Oral-B and Listerine on plaque accumulation (). Conclusion. Ortho-kin showed better effects on decreasing MS and PI because it contained chlorhexidine.

ABSTRACT Objective: To compare the effectiveness of a motionless ultrasonic toothbrush to a manual toothbrush in reducing dental plaque, gingival inflammation, and mutans streptococci in patients with fixed orthodontic appliances. Materials and Methods: Twenty-five orthodontic patients were recruited to this crossover study. The patients were randomized into two groups starting with manual or motionless ultrasonic toothbrushes for 30 days. After a 30-day washout period, the patients switched to the other toothbrush type for 30 days. Plaque and gingival indices were evaluated by two calibrated-blinded examiners before and after each 30-day period of brushing. Salivary samples were also collected for quantification of mutans streptococci. Results: On the bracket side, the motionless ultrasonic toothbrush showed a significantly higher mean plaque index bracket score after 30-day usage than baseline (P = .049), while the manual toothbrush group showed no difference between the before and after brushing periods (P = .10). The changes in plaque index bracket score were significantly more favorable in the manual toothbrush group than in the ultrasonic toothbrush group (P = .04). In contrast, no difference was observed on the nonbracket side. There was no significant difference in the changes of gingival index or the numbers of mutans streptococci between the two groups. Conclusion: Manual toothbrushing performed better than brushing with the motionless ultrasonic toothbrush in plaque removal on the bracket side in orthodontic patients. However, no difference was observed in terms of gingival status and the numbers of mutans streptococci.

SUMMARY Objectives: This double-blind randomized clinical trial evaluated tooth sensitivity (TS) and the effectiveness (EF) of two types of bleaching agents (Trèswhite Ortho [TWO] and Trèswhite Supreme [TWS]) when used in patients wearing orthodontic appliances. Methods and Materials: Forty patients between the ages of 18 and 40 years were randomly stratified, with an equal allocation rate, into two groups (n=20), according to the bleaching agent applied. Tooth color of the six maxillary anterior teeth was measured before and after the treatment with a spectrophotometer. The TS was recorded on three scales before and during the bleaching treatment. Results: With regard to EF, a significant reduction was found (ranging from 7.3-9.6 and 5.3-9.5 Vita scale units for TWO and TWS, respectively, p<0.001); however, there was no statistical difference between the groups (p>0.63). The number of patients with sensitivity was 58.8% and 73.3% for TWO and TWS groups, respectively (p=0.53); however, with each of the three scales used, the intensity of sensitivity was low and there was no statistical difference between TWO and TWS (p>0.05). Conclusions: In spite of producing a side effect of low TS, the two bleaching treatments tested were effective for dental bleaching in patients with fixed orthodontic appliances.

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 Background Migraine is a primary headache disorder and is the most common disabling primary headache disorder that occurs in children and adolescents. A recent study showed that paranasal air suction can provide relief to migraine headache. However, in order to get the maximum benefit out of it, an easy to use effective air sucker should be available. Aiming to fulfil the above requirement, a randomized, double blind control clinical trial was conducted to investigate the efficacy of a recently developed low–pressure portable air sucker. Methods Eighty-six Sri Lankan school children of age 16–19 years with migraine were enrolled for the study. They were randomly allocated into two groups, and one group was subjected to six intermittent ten-second paranasal air suctions using the portable air sucker for 120 s. The other group was subjected to placebo air suction (no paranasal air suction). The effect of suction using portable air sucker was the primary objective but side of headache, type of headache, and gender were also studied as source variables. The primary response studied was severity of headache. In addition, left and right supraorbital tenderness, photophobia, phonophobia, numbness over the face and scalp, nausea and generalized tiredness/weakness of the body were studied. The measurements on all those variables were made before and after suction, and the statistical analysis was performed based on before and after differences. As a follow–up, patients were monitored for 24-h period. Results There was a significant reduction in the severity of headache pain (OR = 25.98, P < 0.0001), which was the primary outcome variable, and other migraine symptoms studied, tenderness (left) (OR = 289.69, P < 0.0001), tenderness (right) (OR > 267.17, P < 0.0001), photophobia (OR = 2115.6, P < 0.0001), phonophobia (OR > 12.62, P < 0.0001) nausea (OR > 515.59, P < 0.0001) and weakness (OR = 549.06, P < 0.0001) except for numbness (OR = 0.747, P = 0.67) in the treatment group compared to the control group 2 min after the suction. These symptoms did not recur within 24-h period and there were no significant side effects recorded during the 24-h observation period. Conclusion This pilot study showed that low–pressure portable air sucker is effective in paranasal air suction, and suction for 120 s using the sucker can provide an immediate relief which can last for more than 24-h period without any side effects.

ABSTRACT Aim Polymethyl-methacrylate (PMMA) is commonly used primarily for baseplates of orthodontic appliances (BOA). The activities of cariogenic bacteria in biofilm on these surfaces may contribute to dental caries, gingival inflammation and periodontal disease. The PMMA incorporated with nanoparticles of silver (NanoAg-I-PMMA) and NanoAg in situ in PMMA (NanoAg-IS-PMMA) have been shown to control the growth of cariogenic bacteria, but clinical trial of anti-cariogenic application of these novel materials in orthodontics has not been evaluated. The main aim of the study is to compare the clinical effectiveness of using NanoAg-IS-PMMA and NanoAg-I-PMMA for construction of new BOA in inhibiting the planktonic growth and biofilm formation of the cariogenic bacteria. Materials and methods Twenty four patients with a median age of 12.6 years (7-15) harboring Streptococcus mutans, Streptococcus sobrinus and Lactobacillus acidophilus as well as Lactobacillus casei participated in the randomized, doubleblind, cross-over study. The experimental BOA, NanoAg-ISBOA and NanoAg-I-BOA, contained 0.5% w/w NanoAg while the control BOA was standard PMMA. Antibacterial effect of NanoAg-IS-BOA and NanoAg-I-BOA was assessed against test cariogenic bacteria by planktonic and biofilm bacterial cells growth inhibition. Results The average levels of test cariogenic bacteria in saliva decreased about 2 to 70 fold (30.9-98.4%) compared to baseline depending on the microorganism type and test BOA. Biofilm inhibition analysis demonstrated that NanoAg-I-BOA and NanoAg-IS-BOA inhibited the biofilm of all test bacteria by 20.1 to 79.9% compared to BOA. NanoAg-IS-BOA had a strong anti-biofilm effect against S. mutans, S. sobrinus and L. casei. However, NanoAg-I-BOA showed only slight antibiofilm effects on test bacteria. Most notably, at all period of the clinical trial, NanoAg-IS-BOA showed a higher antibacterial activity than NanoAg-I-BOA. Conclusion Based on the novel data that presented here, the NanoAg-IS-BOA had strong antimicrobial activity in the planktonic phase and subsequent biofilm formation of the cariogenic bacteria. Clinical significance Wearing of NanoAg-IS-BOA has the potential to minimize dental plaque formation and caries during orthodontic treatment.

PURPOSE: To compare the efcacy between SO and salicylic acid SA in the treatment of plantar keratosis of diabetic patients. METHODS: Randomized, double-blind clinical trial, with 47 type 2 diabetic patients, both sexes and with plantar keratosis. Patients were randomized into 2 groups: G1 (n = 48; treated with 15% SO extract) and G2 (n = 46; treated with 10% AS). The feet were photographed before (D0) and after the treatment (D30) and keratosis areas were measured using the Image J software. For each patient, a lesion in each foot was analyzed. The results were expressed by median. In the statistical analysis, the Wilcoxin test was used to compare the lesion areas before and after treatments and the Mann-Whitney test was used to compare the regression of the lesion areas between the two groups. P <0.05 was adopted. RESULTS: G1 (D0 = 2 8.156 vs D30 = 2.226; p <0.0001) and G2 (D0 = 4.835 vs D30 = 2.059; p <0.0001) showed a difference between the areas (cm ) of the keratosis, 2 before and after the treatment. There was a difference in the regression of the areas (cm ) of keratosis, between G1 and G2, respectively (4.540 vs 1.171, p <0.0001). CONCLUSION: Symphytum ofcinale proved to be more effective than Salicylic Acid in the treatment of plantar keratosis in diabetic patients.

ABSTRACTObjectives: Our aim was to investigate the effect of short-term xylitol consumption on the microbial composition of plaque and saliva. Methods: Twelve volunteers (22-38 yrs) harboring mutans streptococci (MS) participated in the randomized, double-blind, cross-over study. The experimental chewing gum contained 65% xylitol while the control gum contained 63% sorbitol and 2% maltitol w/w. The polyol dose was approximately 6 g/day. Stimulated saliva and plaque samples were collected before and after the two four-week test periods. The samples were cultured for MS, total streptococci, lactobacilli, and total facultatives. A part of the samples were subjected to DNA-DNA hybridizations of 14 microbial plaque species: Actinomyces naeslundii, A. viscosus, Fusobacterium nucleatum, Lactobacillus acidophilus, L. fermentum, L. paracasei, L. rhamnose, L. plantarum, Streptococcus gordonii, S. oralis, S. parasanguis, S. salivarius, S. sanguinis, Veillonella parvula. Results: The MS counts of the plaque samples collected from “caries-prone” tooth sites decreased significantly (P<.01) in the xylitol gum group but not in the sorbitol gum group. Also the plaque MS percentage decreased significantly in the xylitol gum group (P<.01). The salivary MS counts did not decrease either in the xylitol or in the sorbitol gum groups. Nor were changes detected in the salivary levels of total streptococci or lactobacilli. The DNA-DNA hybridization assay revealed no study-induced changes in the microbial composition of the dental plaque. Conclusions: Within the limitations of this pilot study, xylitol consumption reduced MS counts in plaque but appeared not to affect the microbial composition of plaque or saliva in general.

Fluoride Dentifrice

Aim. To evaluate the efficacy of dentifrice containing brazilian red propolis (BRP) in adolescents under orthodontic treatment. Materials and Methods. This is a randomized, double-blind, clinical trial. A total of 92 participants free from caries were randomized into 2 groups; the first received fluoride dentifrice, and the second received fluoride dentifrice incorporated with BRP. The gingival bleeding index (GBI) was recorded, and saliva was collected on the baseline (D0) and after 28 days (D28) for microbiological analysis. Data from GBI and Colony Forming Units (CFU) (log10) were expressed as mean and standard deviation. Results. The two groups reduced GBI significantly, with no difference in the intergroup analysis. In the intragroup analysis, it was observed that G2 (p<0.001) had a significant reduction for Gram-negative bacteria, while there was significance (p<0.001) in the intergroup analysis when compared with G1. For S. mutans bacteria, it was observed that only G2 had a statistically significant reduction (p<0.001), and there was significant reduction (p=0.006) in the intergroup analysis of the G2 group when compared with G1. Conclusions. Dentifrice containing BRP demonstrated better clinical and microbiological activity. Future studies are needed to better identify effects to establish the use of dentifrice containing propolis in biofilm control.
