A method to study sustained antimicrobial activity of rinse and dentifrice components on biofilm viability in vivo

JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 1 2006
H. C. Van Der Mei
Abstract Aim: To develop an improved method for quantitative assessment of antimicrobial efficacy and substantivity of mouth rinses and dentifrices on in vivo treated plaque. Material and Methods: Nine- and 72-h-old plaques were formed in volunteers carrying out standardized hygiene using NaF-containing dentifrice. Plaques were collected before (baseline) in vivo treatment with dentifrices or chlorhexidine mouth rinse, immediately post-treatment and after 1 or 6 h, dispersed in demineralized water and stained with live/dead stain after which bacteria were enumerated. Dispersed baseline plaques were treated with dentifrices or chlorhexidine to determine antimicrobial efficacy against planktonic bacteria. Results: Baseline plaques revealed 56,41% viable organisms in 9- and 72-h-old plaques, respectively. Treatment of planktonic (dispersed baseline plaque) bacteria resulted in 1,4% viable organisms. Chlorhexidine mouth rinse and dentifrices produced strong immediate antimicrobial effects, but after 1 or 6 h, the proportion of viable organisms in 9-h-old plaques rebounded significantly with only chlorhexidine mouth rinse retaining significant efficacy. Seventy-two-hour-old plaques were less susceptible to antimicrobials, although dentifrices appeared more effective after 6 h than initially, whereas efficacy of chlorhexidine rinse continued to drop with time post-treatment. Conclusions: The proposed method holds promise for assessment of both immediate and retained antimicrobial actions of oral treatments against dental plaque in vivo. [source]

The effect of a dentifrice and mouth rinse combination containing amine fluoride/stannous fluoride on plaque and gingivitis: a 6-month field study

JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 7 2005
S. Paraskevas
Abstract Aim: To examine the effect of amine fluoride/stannous fluoride (AmF/SnF2)-containing dentifrice and mouth rinse on plaque formation and gingivitis as compared with habitual oral hygiene procedures with a regular sodium fluoride (NaF) dentifrice. Material and Methods: In total, 22 general practices participated in this research project. The participants (N=281) were randomly assigned into two groups: the test group received an AmF/SnF2 dentifrice,mouth rinse combination and the control group received a NaF-containing dentifrice. The patients were requested to brush twice daily for approximately 2 min. The subjects of the test group had to rinse additionally in the evening for 30 s with 10 ml of the mouth rinse. Results: Both groups started with comparable scores of plaque, bleeding and staining. At 6 months, the plaque scores were 0.95 for the AmF/SnF2 group and 0.99 for the NaF group (decrease of 16% and 10%, respectively). Bleeding scores, although significantly different from baseline, did not show differences between the two regimes. At the end of the experimental period, the overall staining was more pronounced in the AmF/SnF2 group (41%) than the NaF group (26%). Both plaque reduction and increase in staining seemed to be correlated to the amount of mouth rinse used in the test group. Conclusion: In instruction-resistant patients recruited from dental practices, the combined use of AmF/SnF2 did not decrease gingivitis at a significant level in comparison with the regular regime of two times daily brushing with an NaF-containing dentifrice. However, the above-mentioned combination resulted in greater plaque reduction than that observed with the use of the conventional dentifrice. When used according to the manufacturer's instructions, this effect on plaque scores was more pronounced. [source]

In vivo antimicrobial effectiveness of an essential oil-containing mouth rinse 12 h after a single use and 14 days' use

JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 4 2005
D. H. Fine
Abstract Objectives: Two studies were conducted to determine the antimicrobial effect of rinsing with an essential oil-containing mouth rinse 12 h after a single rinse and 12 h after 2 weeks of twice daily rinsing, during the daytime and overnight. Materials and Methods: These studies utilized a randomized, double-blind, controlled crossover design. Following baseline sampling of bacteria from supragingival plaque and the dorsum of the tongue, subjects began twice-daily rinsing with either an essential oil mouth rinse containing 0.09% zinc chloride (Tartar Control Listerine® Antiseptic) or a negative control rinse. Bacterial sampling was repeated 12 h after the first rinse, and again 12 h after the final rinse 14 days later. The sampling schedule was adjusted according to whether the study was investigating daytime or overnight activity. Samples were plated on Schaedlers medium (total anaerobes), Schaedlers Nalidixic/Vancomycin medium (Gram-negative anaerobes), and OOPS medium (volatile sulphur compound (VSC)-producing organisms). Inter-group log10 transformed colony-forming units /ml counts from samples of supragingival plaque and tongue swabs on each of the three media were compared by analysis of covariance. Results: The mean bacterial counts in subjects using the essential oil mouth rinse were significantly lower (p0.005) than mean counts in subjects using the control rinse in all the comparisons, i.e., tongue and supragingival plaque samples on each of three media at two sampling periods in the daytime and overnight study, respectively. Mean bacterial count percent reductions for plaque samples ranged from 56.3 to 95.3; percent reductions for tongue samples ranged from 61.1 to 96.1. There was a trend to higher reductions after 14 days' rinsing than after the initial rinse. Conclusion: Rinsing with the essential oil mouth rinse can have long-lasting effects in reducing anaerobic bacteria overall as well as Gram-negative anaerobes and VSC-producing bacteria. The significant reductions in numbers of these bacteria produced by the essential oil mouth rinse, both in plaque and on the dorsum of the tongue, can play a key role in explaining the essential oil mouth rinse's effectiveness in reducing supragingival plaque and gingivitis as well as its effectiveness in controlling intrinsic oral malodor over prolonged periods.

Development of methods to enhance extrinsic tooth discoloration for comparison of toothpastes

JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 1 2004
2. Two-product clinical study
Abstract Background: Extrinsic staining of teeth is considered to be unsightly and a number of ,whitening' toothpastes have been formulated to inhibit or remove such tooth discoloration. The aim of this study was to compare the stain prevention of two toothpastes. Method: The study was a single-blind, randomised, placebo-controlled, crossover design, balanced for residual effects involving 24 healthy dentate volunteers. The treatments were as follows: (1) a whitening toothpaste product, (2) an experimental toothpaste formulation and (3) water. For each 4-day rinse period, subjects were rendered stain free on the teeth and tongue. Approximately on the hour from 09:00 to 16:00 hours, subjects rinsed with chlorhexidine mouth rinse for 1 min followed by warm black tea for 1 min. The treatment interventions were at 09:00 and 16:00 hours and before the chlorhexidine rinse. The toothpastes were rinsed as 3 g/10 ml water slurries and water as a 10 ml rinse each for 2 min. On day 5, subjects were scored for tooth and tongue stain intensity and area, and the product of these was calculated. The washout period was at least 9 days. Results: Treatment differences for the teeth were highly significant but not for the tongue. Paired contrasts for tooth stain intensity, area and product were mostly all significantly in favour of reduced staining by the experimental formulation compared with water and the whitening product. There were no significant differences between water and the whitening product. Conclusions: Using a forced dietary staining method, the data support a tooth stain-inhibitory/-removal action for the experimental formulation, but not the whitening product. [source]

Levels of aspartate aminotransferase (AST) in saliva of patients with different periodontal conditions

JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 8 2003
Ricardo de Toledo Cesco
Abstract Objectives: The purpose of this study was to evaluate the relationship between aspartate aminotransferase (AST) levels in saliva measured by ReflotronÔ System of Diagnosis and periodontal condition indicated by Community Periodontal Index of Treatment Needs (CPITN). Material and methods: Fifteen patients were assigned to one of four groups C0, C1, C3 and C4, based on their largest CPITN code among the examined sites, totaling 60 participants. About 1.0 ml of non-stimulated saliva was collected from the individuals after a mouth rinse with water. Biochemical analyses of saliva samples were carried out using the proposed system in order to quantify their AST concentration. Results: There were no significant differences between levels (U/ml) of AST (median; interquartile range) from groups C0 (30.9; 14.7,41.7), C1 (30.3; 19.5,39.4) and C3 (35.1; 27.0,63.5). However, group C4 (106.2; 84.4,129.7) differed statistically from the others (p<0.001) and presented AST levels as high as 284.2 U/ml. Gingival bleeding and suppuration were observed in three individuals with concentrations higher than 125.0 U/ml. Conclusion: Levels of AST in saliva from patients presenting CPITN code 4 were higher than from patients coded lower and could be detected by the evaluated diagnostic system. Periodontal destruction such as periodontal pockets, gingival bleeding and suppuration seems to be related to higher AST levels in saliva. Zusammenfassung Ziele: Der Zweck der Studie war die Evaluation der Beziehung zwischen den Levels von Aspartataminotransferase (AST) im Speichel, die mit dem ReflotronÔ System gemessen wurden, und den parodontalen Bedingungen, die mit dem CPITN erfasst wurden. Material und Methoden: 15 Patienten wurden für eine der vier Gruppen C0, C1, C3 und C4 ausgesucht, was aufgrund ihres höchsten CPITN-Wertes unter den überprüften Flächen bei total 60 Teilnehmern geschah. Ungefähr 1.0 ml von nicht stimuliertem Speichel wurde von den Personen nach einer Mundspülung mit Wasser gesammelt. Die biochemischen Analysen der Speichelproben wurden unter Nutzung des vorgeschlagenen Systems durchgeführt, um die AST Konzentration zu bestimmen. Ergebnisse: Es gab keine signifikanten Differenzen zwischen den Levels (U/ml) von AST (Median, Streuung) bei den Gruppen C0 (30.9; 14.7,41.7), C1 (30.3; 19.5,39.4) und C3 (35.1; 27.0,63.5). Jedoch unterschied sich die Gruppe C4 (106.2; 84.4,129.7) signifikant von den anderen (p<0.001) und zeigte AST Level höher als 284.2 U/ml. Gingivale Blutung und Suppuration wurden bei drei Personen beobachtet mit Konzentrationen höher als 125.0 U/ml. Schlussfolgerung: Die Level von AST im Speichel von Patienten mit einem CPITN von 4 waren höher als bei den Patienten, deren CPITN niedriger war. Sie konnten mit dem evaluierten Diagnostiksystem entdeckt werden. Parodontale Destruktion wie parodontale Taschen, gingivale Blutung und Suppuration scheinen zu höheren AST Level im Speichel in Beziehung zu stehen. Résumé Objectifs: Cette étude se propose d'évaluer la relation entre les niveaux d'aspartate aminotransferase (AST) dans la salive, mesuré par le ReflotronÔ System of Diagnosis et la condition parodontale déterminée par le CPITN. Matériel & méthodes: 15 patients (60 au total) furent répartis dans un des 4 groupes C0, C1, C3 et C4, sur la base de leur plus grand code CPITN parmi les sites examinés. Environ 1.0 ml de salive non stimulée fut prélevé après rinçage à l'eau. Des analyses biochimiques des échantillons salivaires furent réalisées avec le système proposé afin de quantifier la concentration en AST. Résultats: Il n'y avait pas de différences significatives entre les niveaux (U/ml) d'AST (median; interquartile range) entre les groupes C0 (30.9; 14.7,41.7), C1 (30.3; 19.5,39.4) et C3 (35.1; 27.0,63.5). Cependant, le groupe C4 (106.2; 84.4,129.7) présentait une différence significative par rapport aux autres (p<0.001) avec des niveaux d'AST allant jusqu'à 284.2 U/ml. Le saignement gingival et la suppuration s'observaient chez trois individus avec des concentrations au dessus de 125.0 U/ml. Conclusion: Les niveaux d'AST dans la salive de patients au CPITN code 4 étaient plus importants que ceux des patients au code CPITN inférieur et pouvaient être détectés par le système de diagnostique évalué. Des destructions parodontales comme des poches parodontales, des saignements gingivaux et des suppurations semblent en relation avec des niveaux plus grands d'AST dans la salive. [source]

Effect of toothpaste on the plaque inhibitory properties of a cetylpyridinium chloride mouth rinse

JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 3 2003
S. Sheen
Abstract Background and aims: Cetylpyridinium chloride (CPC) mouth rinses have moderate plaque inhibitory activity when used alone but rarely have shown adjunctive benefits to tooth brushing with toothpaste. Several explanations for this apparent anomaly can be proferred, including loss of antiseptic activity due to interactions with toothpaste ingredients. The aim of this study was to measure the effect of toothpaste on the plaque inhibitory properties of a CPC mouth rinse using paired rinses of CPC, toothpaste slurry (TP) and water (W). Methods: The study was a single blind, randomised, seven-treatment, cross over design balanced for residual effects, involving 21 healthy, dentate subjects. The paired rinses were: W-CPC, CPC-W, TP-CPC, CPC-TP, W-TP, TP-W and W-W. Rinsing with solutions or slurries was done for 60 s twice per day. On day 1, subjects were rendered plaque free, suspended tooth cleaning and commenced the allocated rinse regimen. On day 5, plaque was scored by index. A 2½ day wash out of normal oral hygiene was allowed between each regimen. Results: The order from lowest to highest plaque scores was as follows: W-CPC = CPC-W < CPC-TP < TP-CPC , W-TP < TP-W < W-W. Several differences in pairs of treatments were statistically significant, the most relevant of which were significantly less plaque with W-CPC compared to TP-CPC, TP-W and W-TP, and significantly more plaque with W-W compared to all other regimens except TP-W. Conclusions: Toothpaste, whilst possessing some plaque inhibitory activity, when used immediately before a CPC mouth rinse adversely affected the plaque inhibitory action of this antiseptic. This in part may explain the reported lack of adjunctive benefits of CPC rinses to normal oral hygiene practices and supports the suggestion, made for chlorhexidine rinses, that their use should follow toothpaste by at least 60 min. Zusammenfassung Die Wirkung von Zahnpasta auf die plaquehemmenden Eigenschaften einer Mundspüllösung mit Cetylpyridinium-Chlorid Grundlagen und Ziel: Cetylpyridinium-Chlorid (CPC) Mundspüllösung haben, wenn sie alleine verwendet werden, eine moderate plaquehemmende Aktivität. Es wurde jedoch selten gezeigt, dass sie zusätzlich zum Zähneputzen Vorteile haben. Mehrere Erklärungen für diese offensichtliche Anomalie können angeboten werden, einschließlich des Verlusts der antiseptischen Aktivität wegen einer Interaktion mit Inhaltstoffen der Zahnpasta. Ziel dieser Studie war es, die Wirkung der Zahnpasta auf die plaquehemmenden Eigenschaften einer CPC-Mundspüllösung zumessen. Es wurde CPC zusammen mit Zahnpasta-Lösung (TP) oder zusammen mit Wasser (W) verwendet. Methoden: Die randomisierte, einfach-blinde-Studie hatte ein 7-Behandlungs- Crossover-Design und war ausgeglichen hinsichtlich der Resteffekte. Einundzwanzig gesunde und bezahnte Personen wurden aufgenommen. Die paarweisen Spülungen waren: W-CPC, CPC-W, TP-CPC, CPC-TP, W-TP, TP-W und W-W. Die Spülungen wurden zweimal pro Tag für 60 Sekunden durchgeführt. An Tag-1 wurde bei der Teilnehmern Plaquefreiheit hergestellt, sie enthielten sich der Mundhygiene und begannen die zugewiesenen Spülungen. An Tag-5 wurde die Plaque mittels Index beurteilt. Zwischen den Spülmaßnahmen war eine 2,5-tägige Auswaschperiode mit normaler Mundhygiene erlaubt. Ergebnisse: Die Reihenfolge vom niedrigsten zum höchsten Plaquewert war W-CPC = CPC-W < CPC-TP < TP-CPC [source]

Effects of date extract on adhesion of Candida species to human buccal epithelial cells in vitro

JOURNAL OF ORAL PATHOLOGY & MEDICINE, Issue 5 2000
Khaled H. Abu-Elteen
Abstract: The adherence of three Candida species to human buccal epithelial cells (BEC) following treatment with different concentrations of date extract was investigated in vitro, as well as the effect of a mouth rinse with date extract on the adhesion of yeast to BEC. Adhesion of C.albicans, C.tropicalis and C.kefyr to BEC was significantly reduced after both short- and long-term periods of yeast exposure to various concentrations of date extract (reduction between 25% and 52% of the control value). A similar inhibition of adherence was observed upon pre-incubation of BEC with date extract. There was a significant reduction (P<0.001) in the adherence of yeast to BEC collected immediately or 5,20 min after an oral rinse with 10% date extract. No statistically significant difference was observed in the adhesion of BEC collected 30 min after an oral rinse with date extract and control BEC. In addition, pre-treatment of either Candida or BEC, or both, with date extract resulted in reduced adherence, the magnitude of which was largest when both types of cells were pre-treated. Date extract also inhibited germ-tube formation of C. albicans (56,85% inhibition), which might contribute to the effects on adherence. [source]

Safety and effectiveness of topical dry mouth products containing olive oil, betaine, and xylitol in reducing xerostomia for polypharmacy-induced dry mouth

JOURNAL OF ORAL REHABILITATION, Issue 10 2007
J. A. SHIP
summary, Polypharmacy is a common cause of salivary hypofunction, producing symptoms of dry mouth or xerostomia, especially among older populations. As the number of older people continues to increase, polypharmacy-induced salivary hypofunction is becoming an increasing problem. Many over-the-counter products are available for relieving symptoms of dry mouth, but few have been tested in controlled clinical investigations. The purpose of this investigation was to evaluate the safety and efficacy of a group of topical dry mouth products (toothpaste, mouth rinse, mouth spray and gel) containing olive oil, betaine and xylitol. Forty adults were entered into this single-blinded, open-label, cross-over clinical study and 39 completed all the visits. Subjects were randomly assigned at baseline to using the novel topical dry mouth products daily for 1 week, or to maintain their normal dry mouth routine care. After 1 week, they were crossed over to the other dry mouth regimen. The results demonstrated that the use of the novel topical dry mouth products increased significantly unstimulated whole salivary flow rates, reduced complaints of xerostomia and improved xerostomia-associated quality of life. No clinically significant adverse events were observed. These data suggest that the daily use of topical dry mouth products containing olive oil, betaine and xylitol is safe and effective in relieving symptoms of dry mouth in a population with polypharmacy-induced xerostomia.

Structured Abstract Authors,,, Maruo IT, Rosa EAR, Maruo H, Tanaka O, Guariza Filho O, Ignácio SA, Camargo ES Objectives,,, To assess total Streptococci (TS) counts and biofilm mass over tooth-tissue-borne palatal expander (TTBPE), as well as the effect of chlorhexidine (CHX) mouth rinse on these variables. Design,,, A cross-sectional study design employed clinical procedures and laboratorial techniques. Setting and Sample Population,,, Patients who had TTBPE removal indicated were divided into two groups: a CHX group (n = 26) in which three times a day of 0.2% CHX digluconate mouth rinses were prescribed 7 days before TTBPE removal; and a control (CON) group (n = 25) in which no antimicrobial treatment was applied. Experimental Variable,,, ,Gender', ,Age', and ,TTBPE wear time' were recorded. After TTBPE removal, biofilm mass was determined by the difference between (TTBPE + biofilm) and (TTBPE only) masses. TS counts were determined by biofilm suspension followed by progressive dilutions and culture on Mitis Salivarius agar with incubation at 37°C for 72 h. Outcome Measure,,, Biofilm mass (mg) and Colony Forming Units of TS,/,mg of biofilm (CFU-TS,/,mg) were calculated. Results,,, Total Streptococci mean values in CHX (6.77 × 106CFU-TS,/,mg) were statistically lower (p < 0.01) than those in CON (3.82 × 107CFU-TS,/,mg), but there was no statistical difference (p > 0.05) between CHX (168.88 mg) and CON (182.04 mg) masses nor statistical correlation (p > 0.05) between biofilm mass and CFU-TS,/,mg in the two groups. Conclusion,,, Chlorhexidine reduces the TS counts in TTBPE, but has no effect on biofilm mass. [source]

Effect of six different peri-implantitis disinfection methods on in vivo human oral biofilm

CLINICAL ORAL IMPLANTS RESEARCH, Issue 8 2010
Martin Gosau
Abstract Objective: The aim of this human in vivo pilot study was to evaluate the efficacy of six antimicrobial agents on the surface decontamination of an oral biofilm attached to titanium implants. Design: For in vivo biofilm formation, we fixed titanium specimens to individual removable acrylic upper jaw splints (14 specimens in every splint), which were worn by four volunteers overnight for 12 h. The specimens were then treated with different antimicrobial agents for 1 min (Sodium hypochlorite, Hydrogen peroxide 3%, Chlorhexidingluconate 0.2%, Plax, Listerine, citric acid 40%). Afterwards, we quantified the total bacterial load and the viability of adhering bacteria by live or dead cell labelling in combination with fluorescence microscopy. Results: The total bacterial load on the titanium surfaces was significantly higher after incubation in the control solution phosphate-buffered saline (PBS) than after disinfection in sodium hypochlorite, hydrogen peroxide, chlorhexidine, Plax, Listerine, and citric acid. Furthermore, a significantly lower ratio between dead and total adhering bacteria (bactericidal effect) was found after incubation in control PBS, Plax mouth rinse, and citric acid than after incubation in sodium hypochlorite, hydrogen peroxide, chlorhexidine, and Listerine. Conclusions: All tested antiseptics seem to be able to reduce the total amount of microorganisms accumulating on titanium surfaces. Furthermore, sodium hypochlorite, hydrogen peroxide, chlorhexidine, and Listerine showed a significant bactericidal effect against adhering bacteria.
