Abstract
AIM To assess user perceptions of different commercially available fluoride mouthwashes (FL-MWs). METHODS A single-blind, randomized clinical trial was conducted. Participants were randomly assigned to a sequence of six different FL-MWs, one of which contained alcohol. For each visit, participants rinsed with one specific mouthwash (15 mL) for 30 s. After rinsing, participants completed a questionnaire with a visual analogue scale. Questions focused on overall taste, mild/pungent feeling, taste duration, foaming effect, burning sensation, sensitivity, numbness, dryness, rinsing time, smell, and colour of the mouthwashes. Descriptive analyses and statistical tests regarding differences among and between the mouthwashes were performed. RESULTS Overall, 53 participants completed the study protocol, including nine who did, however, not rinse with the alcohol-containing mouthwash due to religious reasons. Among the mouthwashes, significant differences were found for foaming effect, sensitivity, rinsing time, smell, and colour (p < 0.05). Pairwise comparison for smell did not reveal a difference, and foaming was within the acceptance range (low to medium foaming). Coloured mouthwashes were more appreciated than transparent solutions (p = 0.00). The mouthwash containing essential oils and alcohol produced significantly more sensitivity (p = 0.00) and, in general, participants experienced the rinsing time significantly longer (p < 0.05) compared to the non-alcohol-containing mouthwashes. CONCLUSION There is heterogeneity in user perceptions and preferences for FL-MWs, with a significant difference in foaming effect, sensitivity, rinsing time, smell, and colour. Coloured mouthwashes are preferred. The mouthwash containing essential oils and alcohol was less acceptable in relation to sensitivity and rinsing time.

Efficacy of 0.05% cetylpyridinium chloride mouthwash as an adjunct to toothbrushing compared with 0.12% chlorhexidine gluconate mouthwash in reducing dental plaque and gingival inflammation: A randomized control trial. Int J Dent Hyg 2023; 21:195-202. [PMID: 35946123 DOI: 10.1111/idh.12614] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Revised: 02/12/2022] [Accepted: 08/06/2022] [Indexed: 01/12/2023]
Abstract
OBJECTIVES This study determined the efficacy of alcohol-free 0.05% cetylpyridinium chloride (CPC) mouthwash as an adjunct to twice-daily toothbrushing in comparison with 0.12% chlorhexidine gluconate (CHX) mouthwash and a placebo in reducing plaque accumulation and gingival inflammation. The side effects of the mouthwashes were also determined. MATERIALS AND METHODS A double-blind, parallel, randomized control trial was conducted with 219 university students who were divided into three trial groups using block randomization: CPC, CHX and placebo groups. Clinical oral examinations to assess dental plaque accumulation (modified Quigley-Hein Plaque Index), gingival health (Löe and Silness Gingival Index) and tooth staining (modified Lobene Stain Index) were performed at baseline and at 6 weeks. RESULTS Plaque and gingivitis scores were not significantly different among participants at baseline. After 6 weeks, plaque and gingivitis scores between the CPC and placebo groups and between the CHX and placebo groups were found to be significantly different. However, there was no significant difference between the CPC and CHX groups. The staining scores of participants in the CPC group were lower than those in the CHX group, but the difference was not significant. Taste alteration and numbness were more common among participants in the CHX group than in the CPC group. No significant difference in the perception of a burning sensation was observed. CONCLUSIONS The 0.05% CPC mouthwash was as efficient as 0.12% CHX mouthwash in reducing dental plaque accumulation and gingival inflammation with fewer side effects, supporting its use as an adjunct to toothbrushing.

Abstract
OBJECTIVE Toothbrushes are colonized by microorganisms, implying a risk of infection. That risk can be reduced by decreasing the microbial contamination of the filaments. Therefore, this study aimed to determine the antiseptic efficacy of a 0.05% chlorhexidine + 0.05% cetylpyridinium chloride mouthwash on toothbrushes. METHODS A total of twelve toothbrushes used three times/day for 14 days by orally and systemically healthy people were randomly split into two groups, and their heads were immersed for 2 h in PBS (control) or Perio·Aid Active Control (treatment). The microorganisms were recovered, and their number was calculated by culture, quantitative PCR, and viability PCR. Statistical differences were first assessed with a two-way mixed ANOVA and subsequently with Student's t-test. RESULTS The results showed no statistical differences in the total number of cells for the treatment (mean ± CI95% of 7.27 ± 1.09 log10 bacteria/ml) and the control (7.62 ± 0.64 log10 bacteria/ml) groups, but a significantly lower number of live cells in the treatment group (4.58 ± 0.61 log10 viable bacteria/ml and 2.15 ± 1.42 log10 cfu/ml) than in the control group (6.49 ± 1.39 log10 viable bacteria/ml and 5.04 ± 0.93 log10 cfu/ml). CONCLUSIONS Based on our findings, sanitization of toothbrushes with this mouthwash reduces the number of live microorganisms adhered to the filaments. Such decrease of the bacterial load could include bacteria from the oral cavity, from the environment, and from nearby toothbrushes since the quantification was not limited to any bacterial taxon.

Abstract
Antimicrobial surfactants contained in mouthrinse have excellent efficacy, but are not retained on the tooth surface (are rinsed away) due to their low water resistance and thus do not exhibit sustained antibacterial activity. We have developed a new coating method using graphene oxide (GO) that retains the surfactant on the tooth surface even after rinsing with water, thus providing a sustained antibacterial effect. Ultra-thin films of GO and an antimicrobial agent were prepared by (1) applying GO to the substrate surface, drying, and thoroughly rinsing with water to remove excess GO to form an ultrathin film (almost a monolayer, transparent) on the substrate surface, then (2) applying antimicrobial cationic surface active agents (CSAAs) on the GO film to form a composite coating film (GO/CSAA). GO/CSAA formation was verified by scanning electron microscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, and ζ-potential and contact angle measurements. GO/CSAA was effective at inhibiting the growth of oral pathogens for up to 7 days of storage in water, and antibacterial activity was recovered by reapplication of the CSAA. Antibacterial GO/CSAA films were also formed on a tooth substrate. The results suggest that GO/CSAA coatings are effective in preventing oral infections.

Antiplaque and antigingivitis efficacy of cetylpyridinium chloride with zinc lactate compared with essential oil mouthrinses: Randomized clinical trial. J Am Dent Assoc 2020; 152:105-114. [PMID: 33358239 DOI: 10.1016/j.adaj.2020.09.021] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2020] [Revised: 09/22/2020] [Accepted: 09/24/2020] [Indexed: 10/22/2022]
Abstract
BACKGROUND The authors of this study aimed to evaluate the clinical antiplaque and antigingivitis effects of 3 oral hygiene regimens: toothbrushing with standard fluoride toothpaste and manual toothbrush and using a mouthrinse containing cetylpyridinium chloride, zinc lactate, and fluoride (CPC + Zn + F) in an alcohol-free base; toothbrushing with standard fluoride toothpaste and manual toothbrush and using a mouthrinse containing essential oils (EO) in an alcohol-free base; and toothbrushing with manual toothbrush and standard fluoride toothpaste and manual toothbrush (control). METHODS The participants (N = 120) were randomly assigned to study groups and followed the assigned regimens twice daily for 6 weeks. The participants were examined by a calibrated examiner for the Quigley-Hein plaque index (Turesky modification) and Löe-Silness gingival index at baseline, week 4, and week 6. Statistical analyses were performed separately for plaque and gingival indexes by means of analysis of variance, paired t test, and analysis of covariance (α = 0.05). RESULTS At week 4, the CPC + Zn + F group presented additional reductions in dental plaque compared with EO and control groups of (21.4% [P < .001] and 31.4% [P < .001], respectively). After 6 weeks, these values were 26.7% (P < .001) and 44.8% (P < .001), respectively. For Löe-Silness gingival index, additional reduction in the CPC + Zn + F group compared with EO were 10.6% (P < .001) and 13.7% (P < .001) at 4 and 6 weeks, respectively. Compared with control, these reductions were 13.6% (P < .001) and 17.8% (P < .001), respectively. CONCLUSIONS The regimen including a mouthrinse containing CPC + Zn + F presented higher antiplaque and antigingivitis effects than EO and control regimens. PRACTICAL IMPLICATIONS A mouthrinse containing CPC + Zn + F is an effective protocol for the control of dental plaque and gingivitis.

Abstract
Cetylpyridinium chloride (CPC), a quaternary ammonium compound and cationic surfactant, is used in personal hygiene products such as toothpaste, mouthwash, and nasal spray. Although public exposure to CPC is frequent, its pulmonary toxicity has yet to be fully characterized. Due to high risks of CPC inhalation, we aimed to comprehensively elucidate the in vitro and in vivo toxicity of CPC. The results demonstrated that CPC is highly cytotoxic against the A549 cells with a half-maximal inhibitory concentration (IC50 ) of 5.79 μg/ml. Following CPC exposure, via intratracheal instillation (ITI), leakage of lactate dehydrogenase, a biomarker of cell injury, was significantly increased in all exposure groups. Further, repeated exposure of rats to CPC for 28 days caused a decrease in body weight of the high-exposure group and the relative weights of the lungs and kidneys of the high recovery group, but no changes were evident in the histological and serum chemical analyses. The bronchoalveolar lavage fluid (BALF) analysis showed a significant increase in proinflammatory cytokines interleukin (IL)-6, IL-1β, and tumor necrosis factor (TNF)-α levels. ITI of CPC induced focal inflammation of the pulmonary parenchyma in rats' lungs. Our study demonstrated that TNF-α was the most commonly secreted proinflammatory cytokine during CPC exposure in both in vitro and in vivo models. Polymorphonuclear leukocytes in the BALF, which are indicators of pulmonary inflammation, significantly increased in a concentration-dependent manner in all in vivo studies including the ITI, acute, and subacute inhalation assays, demonstrating that PMNs are the most sensitive parameters of pulmonary toxicity.

Abstract
OBJECTIVE To evaluate the antimicrobial property of cetylpyridinium chloride (CPC) when polymerized with cold cure acrylic and to assess the duration of its release from modified acrylic. MATERIALS AND METHODS CPC was added in different concentrations (0%, 2.5%, 5%, and 10%) to cold cure acrylic resin and 180 acrylic discs were prepared. These were divided into four groups of 45 each depending on the concentration of CPC. The antimicrobial property of the modified acrylic for Streptococcus mutans was tested using disc diffusion assay in agar. The duration of release of CPC from self-cure acrylic was tested with optical density reading of solutions by ultraviolet spectrophotometer. The effect of addition of CPC on diametral tensile strength (DTS) of acrylic was tested using UTM (Instron) and the effect of water aging on modified acrylic was compared with unaged specimens. RESULTS AND CONCLUSION The normality of the data was checked by Shapiro-Wilktest, and as the data failed to show normal distribution, inferential statistics were performed using nonparametric tests of significance. Antimicrobial activity of modified acrylic increased with increase in CPC concentration. Greatest CPC release was observed on the seventh day with a decrease in release from 7 to 180 days. There was a decrease in the diametral strength of the modified resin and water aging had a significant effect on the DTS of the modified resin.

Abstract
OBJECTIVE To evaluate the addition of titanium dioxide (TiO2) nanoparticles and cetylpyridinium chloride (CPC) on the compressive strength and antibacterial activity of conventional glass-ionomer cement (GIC). STUDY DESIGN TiO2 nanoparticles enriched GIC was prepared by adding 3% TiO2 nanoparticles (w/w) into the powder component of conventional GIC. CPC containing GIC was developed by incorporating 1% CPC (w/w) into conventional GIC powder. Samples were segregated into three groups: GIC with 3% TiO2 nanoparticles, GIC with 1% CPC and unmodified conventional GIC. Compressive strength was assessed using the universal testing machine on cylindrical specimens made from each material. Antibacterial activity was assessed by measuring inhibition zones on Mitis Salivarius Bacitracin (MSB) agar inoculated with pure strain of Streptococcus mutans (S. mutans). RESULTS GIC containing TiO2 nanoparticles exhibited significantly greater compressive strength as compared with CPC and conventional GIC groups (P < 0.01). However, there was no significant difference between the compressive strengths of CPC and conventional GIC group (P >0.05). Antibacterial activity was significantly greater for TiO2 group than conventional GIC (P <0.05). CPC increased the antibacterial activity of conventional GIC, though not significantly. CONCLUSION The addition of 3% TiO2 nanoparticles improves the compressive strength of GIC as well as its antibacterial activity against S. mutans.

Resumo O objetivo do presente estudo foi avaliar clinicamente em humanos o efeito antiplaca de Ocimum gratissimum (Og). Quinze adultos saudáveis participaram deste estudo cruzado, duplo-cego, por meio de um modelo de acúmulo de placa parcial de 3 dias. Os voluntários aboliram qualquer método mecânico de higiene oral e foram inicialmente designados para usar os seguintes enxaguatórios bucais: água destilada (solução AD), digluconato de clorexidina a 0,12% (solução CLX) ou 10% Og (solução Og). O índice de placa (IPL) foi registrado em todos os dentes inferiores no final do experimento e os testes estatísticos Kruskal-Wallis (α=0,05) e Mann-Whitney (α=0,05) foram utilizados para estimar a diferença entre os grupos. Os resultados clínicos demonstraram diferença estatisticamente significante entre os três grupos (p<0,05), favorecendo os grupos CLX e Og; entretanto o grupo CLX foi mais efetivo que o grupo Og (p<0,05). Os enxaguatórios bucais contendo digluconato de clorexidina e Og a 10% foram capazes de reduzir a formação de nova placa bacteriana, mas Og mostrou resultados mais limitados em comparação ao digluconato de clorexidina.

Abstract
Cationic surfactants are widely used in biological and industrial processes. Notably, surfactants with pyridinium salts, such as cetylpyridinium bromide (CPB), have diverse applications. The cetylpyridium cation has a quaternary nitrogen in the aromatic heterocyclic ring of the headgroup and 16 carbons in the hydrocarbon tail. At present and in the past, it has been widely used in germicides. Recently, several interesting applications of CPB have been explored, including its use in protein folding, polymerization, enzyme studies, and gene delivery as well as in pharmaceuticals as a drug delivery tool. A molecular-level understanding of CPB and its micelle in solution can enhance its development in such applications. Herein, we have proposed the first united-atom force field for CPB that yields stable micellar aggregates in molecular dynamics (MD) simulations. The force field is validated through classical MD simulations of the CPB monomer in pure water and 1-octanol as well as in an aqueous CPB micelle. We have performed principal component analysis (PCA) and calculated the translational and rotational diffusion coefficients, spatial distribution of solvent, counterion distribution, and rotational correlation time of CPB molecule in solutions and in micelle, comparing these data to previous experimental and theoretical results for a strong validation of the force field. PCA confirms that the pyridinium ring remains planar, whereas the movement of the hydrophobic tail region leads to conformational changes during the simulations. The collective modes of the pyridinum ring were identical for CPB molecule in solution and micelle, but conformational dynamics of the CPB tail were restricted in the micelle relative to motions in water and 1-octanol. Using this force field, a spherical CPB micelle was shown to be stable throughout the course of simulation, and its solvation and structural properties are characterized.

Abstract
Also note that structured abstracts are not allowed per journal style: What is the effect of a mouthwash containing various active chemical ingredients on plaque control and managing gingivitis in adults based on evidence gathered from existing systematic reviews? The summarized evidence suggests that mouthwashes containing chlorhexidine(CHX) and essential oils (EO) had a large effect supported by a strong body of evidence. Also there was strong evidence for a moderate effect of cetylpyridinium chloride(CPC). Evidence suggests that a CHX mouthwash is the first choice, the most reliable alternative is EO. No difference between CHX and EO with respect to gingivitis was observed.

Abstract
OBJECTIVE To evaluate the effectiveness of 0.07% cetylpyridinium chloride (CPC) mouth rinse for reduction of gingival inflammation and inhibition of plaque compared to a vehicle control (VC) mouth rinse over a 6-month period. MATERIALS & METHODS Participants (n = 62) used their randomly assigned product as adjunct to toothbrushing. Bleeding, plaque and staining scores were assessed at baseline, 3 and 6 months. Plaque and saliva samples were taken at each assessment monitoring possible shifts in the composition of the microbiota. RESULTS A significant difference (P = 0.002) in favour of the CPC mouth rinse, with respect to plaque scores, was found. Bleeding scores at 6 months were not significantly different (P = 0.089). However, when correcting for baseline values, a tendency towards a significant difference in bleeding scores at end trail was observed in favour of the CPC mouth rinse (P = 0.061). Regarding staining at 3 and 6 months, a small but significant difference (8.6% and 10.4%, respectively) (P < 0.0001) was observed with lower scores for the VC group. There was a significant reduction in total anaerobic count in the CPC group at 6 months (P < 0.05). The ratio of aerobes/anaerobes was markedly increased at 3 months, especially in the CPC group. No further differences were observed between groups at 6 months. CONCLUSIONS The use of 0.07% CPC mouth rinse was significantly more effective in reducing plaque scores than the vehicle control. Bleeding scores were not different at 6 months. The test product was well accepted and did not cause any serious clinical side effects or negatively affected the microbiota.

Abstract
AIM To assess the efficacy of a 0.07% cetylpyridinium chloride (CPC) mouth rinse in the control of plaque and gingival inflammation during a 6-month period. MATERIAL AND METHODS Adult subjects with moderate gingivitis were selected [≥40% bleeding on marginal probing (BOMP)]. After retrieving microbiological samples and evaluating the clinical parameters (plaque, BOMP and stain indexes), a professional prophylaxis was performed and subjects were randomly assigned to the test (CPC mouth rinse) or to the placebo group. Subjects were re-assessed after 3 and 6 months. RESULTS A total of 67 patients (35 test, 32 placebo) were included in the analysis. At 6 months, intra-group significant plaque reductions were observed in the test group (0.691, p < 0.001), but not in the placebo (0.181, p = 0.653). At 6 months, the mean BOMP values were lower in the test group (p = 0.052). Changes between baseline and 6 months were significantly higher in the test group both for plaque (p = 0.002) and BOMP (p = 0.037) when compared with the placebo. A microbiological impact was observed in the test group, especially for Prevotella intermedia. CONCLUSION The evaluated 0.07% CPC-based mouth rinse, used three times per day adjunctively to mechanical tooth cleaning, prevents plaque accumulation and gingival inflammation, as compared to the placebo, for at least 6 months.

Abstract
OBJECTIVES The aim of the study was to compare the antimicrobial activity of a mouth rinse containing chlorhexidine and cetylpyridinium chloride (MR1) with a stannous fluoride-based mouth rinse (MR2) in vitro. MATERIALS AND METHODS Samples of the tongues from 10 subjects with and 10 subjects without halitosis were inoculated on blood agar plates. The agar was perforated, and the cylindrical holes were filled either with mouth rinse MR1 or with mouth rinse MR2. After incubation, inhibition zones of the whole tongue microbiota and Fusobacterium nucleatum were measured. In addition, MR1 and MR2 were applied in a short interval killing test (SIKT) on four oral pathogens Porphyromonas gingivalis, Prevotella intermedia, F. nucleatum and Aggregatibacter actinomycetemcomitans. Total viable cell counts were made after two minutes of incubation with increasing concentrations of MR1 and MR2. RESULTS MR1 showed a significantly higher in vitro antimicrobial activity against the whole tongue microbiota and F. nucleatum than MR2 in both groups of subjects. In the SIK test, MR1 showed a significantly greater killing capacity than MR2. The results show that a mouth rinse with low concentrations of chlorhexidine and 0.05% cetylpyridinium chloride appears to be more effective in inhibiting growth of the human tongue microbiota in vitro than a fluoride/stannous fluoride-containing mouth rinse. CONCLUSION This in vitro observation supports the use of chlorhexidine and cetylpyridinium chloride in the treatment of oral halitosis.
