Evaluation of the efficacy of a polyherbal mouthwash containing Zingiber officinale, Rosmarinus officinalis and Calendula officinalis extracts in patients with gingivitis: A randomized double-blind placebo-controlled trial

BackgroundGingivitis is a highly prevalent periodontal disease resulting from microbial infection and subsequent inflammation. The efficacy of herbal preparations in subjects with gingivitis has been reported in some previous studies. ObjectiveTo investigate the efficacy of a polyherbal mouthwash containing hydroalcoholic extracts of Zingiber officinale, Rosmarinus officinalis and Calendula officinalis (5% v/w) compared with chlorhexidine and placebo mouthwashes in subjects with gingivitis. MethodsSixty patients participated in this randomized double-blind placebo-controlled trial and were randomly assigned to the polyherbal mouthwash (n = 20), chlorhexidine mouthwash (n = 20) or placebo mouthwash (n = 20). Participants were instructed to use the mouthwash twice a day (after breakfast and dinner) for 30 s for a period of two weeks. Gingival and plaque indices were assessed using MGI, GBI and MQH scales at baseline, day 7 and day 14 of the trial. ResultsThere were significant improvements in all assessed efficacy measures i.e. MGI, GBI and MQH scores from baseline to the end of trial in both polyherbal and chlorhexidine mouthwash groups; however, the scores remained statistically unchanged in the placebo group. MGI, BGI and MQH scores in the treatment groups were significantly lower compared with those of the control group at both day 7 and day 14 of the trial. However, there was no significant difference between the polyherbal and chlorhexidine groups, neither at day 7 nor day 14 of the trial. Polyherbal mouthwash was safe and there was neither report of adverse reactions, nor any drop-out during the course of study. ConclusionPolyherbal mouthwash containing hydroalcoholic extracts of Z. officinale, R. officinalis and C. officinalis (5%) was effective in the treatment of gingivitis and its efficacy was comparable to that of chlorhexidine mouthwash.

The efficacy of erythropoietin mouthwash in prevention of oral mucositis in patients undergoing autologous hematopoietic SCT: a double-blind, randomized, placebo-controlled trial.

Oral mucositis (OM) as a complication of high-dose chemotherapy is frequently occurred in hematopoietic stem cell transplantation (HSCT) settings. Erythropoietin (EPO) has anti-inflammatory, antioxidant and wound-healing properties and therefore could have an important role in the prevention of OM. We conducted a double-blind, randomized, placebo-controlled trial to evaluate the EPO mouthwash effect on OM incidence and severity in 80 patients with non-Hodgkin's lymphoma, Hodgkin disease (HD) or multiple myeloma, undergoing autologous hematopoietic stem cell transplantation. Patients received either EPO mouthwash (50 IU/ml, 15 ml four times a day) (n = 40) or placebo (n = 40) from the starting day of high-dose chemotherapy until day +14 after transplantation or until the day of discharge from the hospital, whichever occurred first. OM was evaluated daily for 21 days after transplantation or until resolution of OM according to World Health Organization oral toxicity scale. The incidence of OM (grades 1-4) in the EPO mouthwash group and control group was significantly different (27.5% vs 77.5%, p < 0.001). The mean ± SD of two other parameters of OM including maximum intensity OM score (0.60 ± 1.06 vs 1.67 ± 1.27) and average intensity OM score (0.47 ± 0.80 vs 1.28 ± 0.86) was significantly lower in the intervention group (p < 0.001). Moreover, the mean ± SD duration of OM was also significantly shorter among the EPO mouthwash recipients (1.92 ± 3.42 days vs 5.42 ± 3.86 days, P < 0.001). Also, the duration of neutropenic fever was significantly shorter in the intervention group (2.12 ± 2.42 days vs 3.95 ± 4.01 days, p = 0.016). It is concluded that EPO mouthwash can reduce the incidence and duration of OM. Copyright © 2015 John Wiley & Sons, Ltd.

Optimization of Noninvasive Methods of DNA Collection for Genetic Testing [287

INTRODUCTION: The new era of molecular diagnostics based on advanced DNA sequencing technologies opens possibilities for targeted genetic screening of high-risk populations. Biological samples collected in a noninvasive manner such as mouth and buccal cells can supply DNA for genetic testing. METHODS: A total of 110 volunteers participated in a study comparing different noninvasive methods of DNA collection (cotton-tipped swab, multiple cytology brushes, alcohol-containing mouthwash solution) and different times of specimen storage before extraction (same day, 2, 5, 7, and 14 days postcollection) for BRCA testing by next-generation sequencing. Volunteers were divided into two groups: mouthwash collection (n=60) and buccal swabs (n=50). For DNA extraction, we compared two extraction kits (Thermo GeneJET and Qiagen). Individual compliance, sufficient quantity and quality of collected DNA, and cost of each method were assessed. RESULTS: The average total DNA yield was found to be significantly higher in the mouthwash group (4,185±1,916.7 ng) in comparison with the cotton-tipped swab (95.1±81.4 ng), flocked brush (164.7±143.0 ng), and cytology brushes (1,123.4±1,281 ng). Mouthwash DNA collection was also the most cost-effective method. There was no significant difference in the DNA yield when samples were stored at room temperature for up to 14 days before extraction. CONCLUSION: Our results indicated that noninvasive methods of DNA collection can provide sufficient DNA yield and quality for genetic testing. Buccal cells collected using commercially available mouthwash provide the highest DNA yield and can be stored for up to 14 days without a significant decrease of genetic material quality.

The comparative effect of propolis in two different vehicles; mouthwash and chewing-gum on plaque accumulation and gingival inflammation.

Objective:In general, chemical plaque agents have been used in mouthwashes, gels, and dentifrices. In some situations, application of mouthwashes and dentifrices can be difficult. Therefore, different approaches for oral health-care have been needed. The aim of this study was to evaluate the effect of propolis chewing-gum compared to propolis-containing mouthwash on gingival inflammation and plaque accumulation on patients that refrained from daily oral hygiene procedures for 5 days.Materials and Methods:10 college students with systemically healthy and very good oral hygiene and gingival health were included in this randomized, single-blind, crossover 5-day plaque regrowth with a 3-day washout period clinical study. After plaque scores were reduced to zero, participants were asked to refrain from oral hygiene procedures and allocated to either propolis mouthwash or chewing-gum group. Chewing-gum was performed after meals 3 times a day for 20 min mouthwash group was instructed to rinse mouthwash 2 times a day for 1 min. On day 5, the clinical periodontal measurements containing plaque and gingival indexes were taken from the participants.Results:The both plaque and gingival indexes of propolis mouthwash group were significantly lower than that of the propolis chewing-gum group (P = 0.005).Conclusion:It was demonstrated that the propolis mouthwash was more effective than the propolis chewing gum on the plaque inhibition and the gingival inflammation.

Comparative evaluation of honey, chlorhexidine gluconate (0.2%) and combination of xylitol and chlorhexidine mouthwash (0.2%) on the clinical level of dental plaque: A 30 days randomized control trial.

Aim:To compare the effect of honey, chlorhexidine mouthwash and combination of xylitol chewing gum and chlorhexidine mouthwash on the dental plaque level.Materials and Methods:Ninety healthy dental students, both male and female, aged between 21 to 25 years participated in the study. The subjects were randomly divided into three groups, i.e. the honey group, the chlorhexidine gluconate mouthwash group and the combination of xylitol chewing gum and chlorhexidine (CHX) mouthwash group. The data was collected at the baseline, 15th day and 30th day; the plaque was disclosed using disclosing solution and their scores were recorded at six sites per tooth using the Quigley and Hein plaque index modified by Turesky-Gilmore-Glickman. Statistical analysis was carried out later to compare the effect of all the three groups. P ≤ 0.05 was considered as statistically significant.Results:Our result showed that all the three groups were effective in reducing the plaque but post-hoc LSD (Least Significant Difference) showed that honey group and chlorhexidine + xylitol group were more effective than chlorhexidine group alone. The results demonstrated a significant reduction of plaque indices in honey group and chlorhexidine + xylitol group over a period of 15 and 30 days as compared to chlorhexidine.

Effect of Inhabitation Mouthwash Solution Containing Chlorine Dioxide (Pro Fresh&lt;sup&gt;&#174;&lt;/sup&gt;) on Oral Malodor

Recently, the interest in oral malodor has been grown and the number of people having trouble with oral malodor is increasing year by year. Generally, as the branch of medicine which deals with patients complaining about oral malodor, dentistry is mostly chosen. On the current situation, however, the dental office side typically finds it difficult to deal with several kinds of oral malodor which show no improvement even though cavities or periodontal disease is completely cured. Main components to cause oral malodor are volatile sulfur compounds (methyl mercaptan, dimethyl sulfide, hydrogen sulfide); in the present study, therefore, the effect of mouthwash solution containing chlorine dioxide to relieve oral malodor and increase saliva production was tested. The subjects were 92 patients (Control group: 2 males, 3 females, age; 30.8 ± 4 years old, Mouthwash group: 28 males, 59 females, age: 36.9 ± 1.3 years old) who visited the hospital complaining about oral malodor. Intraoral gas, exhaled gas, the saliva production at rest, the ability for salivation and the buffering ability of saliva were examined twice, before the subjects used the mouthwash solution every day for one month. The simple chromatography oral chroma, which was insulated from the influence of temperature and humidity and also was able to measure with a high degree of accuracy, was used to measure odor as the device analysis method. The control group did not change in VSCs, saliva production and the buffering ability of saliva. After using mouthwash solution, the concentration of the 3 major components gas of intraoral gas and exhaled gas, i.e. methyl mercaptan, dimethyl sulfide, hydrogen sulfide, were all decreased. As for hydrogen sulfide, intraoral gas (from 225.8 ± 28.1 ppb to 41.1 ± 8.8 ppb) and exhaled gas (from 212.0 ± 50.4 ppb to 34.6 ± 16.6 ppb) was significantly decreased. Also, saliva production at rest (from 1.3 ± 0.1 ml to 1.7 ± 0.1 ml) and the ability to salivate (from 4.5 ± 0.3 ml to 5.1 ± 0.3 ml) were both significantly increased. As for the buffering ability of saliva, significant changes were not detected on the change of salivary pH after using mouthwash solution, and it did not have any effects on the buffering ability of saliva. In conclusion, these results suggest that the mouthwash solution containing chlorine dioxide has significant effects on inhibiting malodor.

Efficacy of 0.25% Lemongrass Oil Mouthwash: A Three Arm Prospective Parallel Clinical Study.

Chlorhexidine mouthwash has earned eponym of gold standard to treat and/or prevent periodontal diseases. However, the present study was carried out to explore an alternative herbal mouthwash. To compare the anti-plaque and anti-gingivitis efficacy of a 0.25% lemongrass oil mouthwash to that of 0.2% chlorhexidine mouthwash. A double-blinded parallel designed clinical trial with 60 subjects was taken for the study. Baseline plaque index (PI) & gingival index (GI) score was recorded. Oral prophylaxis was done and the plaque score was set at zero. Then, subjects were randomly allocated into 3 groups (N=20 in each): 0.25% lemongrass oil mouthwash, 0.2% chlorhexidine mouthwash and oral prophylaxis only. Subjects were asked to swish with respective mouthwash twice daily for 21 days. Subjects were again re-evaluated on 14(th) and 21(st) day for GI and PI. Comparison of the mean difference among the variables was performed by parametric tests. Lemongrass oil mouthwash group showed highest reduction in GI & PI at both 14(th) and 21(st) day, which was statistically significant (p≤0.05). Lemongrass oil mouthwash can also be used as a good herbal alternative to chlorhexidine mouthwash, so further studies are needed.

Morphine mouthwash for the management of oral mucositis in patients with head and neck cancer.

Background:Oral mucositis is a debilitating side effect of cancer treatment for which there is not much successful treatments at yet. We evaluated the effectiveness of topical morphine compared with a routine mouthwash in managing cancer treatment-induced mucositis.Materials and Methods:Thirty head and neck cancer patients with severe mucositis (World Health Organization Grade III or IV) were randomized into the morphine and magic mouthwash groups. Patients received morphine sulfate 2% or magic solution (contained magnesium aluminum hydroxide, viscous lidocaine, and diphenhydramine), 10 ml for every 3 h, six times a day, for 6 days. Both groups received same dietary and oral hygiene instructions and care. Mucositis was graded at baseline and every 3 days after treatment. Patients’ satisfaction and drug effect maintenance were also evaluated.Results:Twenty-eight patients (mean age of 49.5 ± 13.2 years, 63.3% female) completed the trial; 15 in the morphine group and 13 in the magic group. There was a decrease in mucositis severity in both of the morphine (P < 0.001) and magic (P = 0.049) groups. However, at the 6th day, more reduction was observed in mucositis severity in the morphine compared with magic group (P = 0.045). Drug effect maintenance was similar between the two groups, but patients in the morphine group were more satisfied by their treatments than those in the magic group (P = 0.008).Conclusions:Topical morphine is more effective and more satisfactory to patients than the magic mouthwash in reducing severity of cancer treatment-induced oral mucositis. More studies with larger sample size and longer follow-up are required in this regard.

Are herbal mouthwash efficacious over chlorhexidine on the dental plaque?

Aim:To compare the effect of herbal extract mouthwash and chlorhexidine mouthwash on the dental plaque level.Materials and Methods:The subjects (60 healthy medical students aged ranges between 20 and 25 years) were randomly divided into two groups, that is, the herbal group and the chlorhexidine gluconate mouthwash group. The data were collected at the baseline and 3 days. The plaque was disclosed using erythrosine disclosing agent and their scores were recorded using the Quigley and Hein plaque index modified by Turesky-Gilmore-Glickman. Statistical analysis was carried out later to compare the effect of all the two groups.Results:Our result showed that the chlorhexidine group shows a greater decrease in plaque score followed by herbal extract, but the result was statistically insignificant.Conclusion:The results indicate that herbal mouthwash may prove to be an effective agent owing to its ability to reduce plaque level, especially in low socioeconomic strata.

Effect of Two Herbal Mouthwashes on Gingival Health of School Children

This study aimed at determining the effect of indigenously prepared neem and mango chewing stick mouthwashes on plaque and gingival indices. A sample of 105 children aged 12-15 years was randomized into three groups, namely neem, mango, and chlorhexidine mouthwash groups. All the children were examined at baseline and gingival and plaque indices were recorded. Baseline scores for plaque and gingivitis were fair and moderate, respectively, in all the three groups and there existed no statistically significant difference among them. Ten millilitres each of herbal and chlorhexidine mouthwashes (0.2%) were administered according to the group allocation twice daily for 21 days. Indices were reassessed at 21 days (immediately after intervention) and at 1 month, 2 months, and 3 months after discontinuing the mouthwashes. Statistically significant reduction (P < 0.001) in plaque index was found in all the three mouthwash groups at 21 days and at 1 month from discontinuing the mouthwash. Chlorhexidine additionally showed statistically significant reduction in plaque index at 2 months from discontinuing the mouthwash. Statistically significant reduction (P < 0.001) in gingival index was found in all the three mouthwash groups at 21 days (immediately after discontinuing the mouthwash) and at 1 and 2 months from discontinuing the mouthwash. To conclude, all the three mouthwashes were effective antiplaque and antigingivitis agents. Chlorhexidine and neem possess equivalent efficacy in reducing plaque, while chlorhexidine has superior antigingivitis properties.

The efficacy of three formulations of Lippia sidoides Cham. essential oil in the reduction of salivary Streptococcus mutans in children with caries: A randomized, double-blind, controlled study

Essential oils of many plants have been previously tested in the treatment of oral diseases and other infections. This study was a randomized, double-blind, in parallel with an active control study, which aimed to evaluate the efficacy of three formulations of the Lippia sidoides Cham. essential oil (LSO) in the reduction of salivary Streptococcus mutans in children with caries. 81 volunteers, aged 6–12 years, both genders, with caries, were recruited to participate in this study, and randomly assigned to either one of five different groups. Each group received topical treatment with either 1.4% LSO toothpaste, 1.4% LSO gel, 0.8% LSO mouthwash, 1% chlorhexidine gel, or 0.12% chlorhexidine mouthwash. A 5-ml volume of each gel was placed inside disposable trays, and applied for 1min, every 24h, for 5 consecutive days. The mouthwash groups used 5-ml volume of a mouthwash inside disposable syringes. In the toothpaste group, children brushed their teeth for 1min, once a day for 5 days. Saliva was collected before and after treatment. MS colonies were counted, isolated and confirmed through biochemical tests. Differences in MS levels measured in different days within the same treatment group was only verified with LSO toothpaste, chlorhexidine gel and chlorhexidine mouthwash. Comparison between groups of LSO mouthwash, toothpaste and gel showed that the toothpaste group expressed significantly lower MS levels than the mouthwash and gel groups at day-30. Chlorhexidine significantly reduced MS levels after 5 days of treatment, but these levels returned to baseline in other periods of the study. LSO toothpaste reduced MS levels after 5 days of treatment, and MS levels remained low and did not return to baseline during subsequent analysis. Hence, LSO toothpaste demonstrated the most long-lasting MS reduction in saliva, whereas other LSO formulations did not effectively reduce MS levels in children with dental caries.

Preliminary Antiplaque Efficacy of &lt;i&gt;Aloe Vera&lt;/i&gt; Mouthwash on 4 Day Plaque Re -Growth Model: Randomized Control Trial

Due to increasing resistance to antibiotics and rising incidence of oral diseases, there is a need for alternative treatment modalities to combat oral diseases. The aim of the present study was to access the effect of Aloe vera mouthwash on the dental plaque in the experimental period of 4 days and to compare it with the bench mark control chlorhexidine and placebo (saline water). A total of 300 systemically healthy subjects were randomly allocated into 3 groups: Aloe vera mouthwash group (n=100), control group (=100)-chlorhexidene group and saline water-Placebo (n=100). To begin with, Gingival index (GI) and plaque index (PI) were recorded. Then, baseline plaque scores were brought to zero by professionally cleaning the teeth with scaling and polishing. After randomization of the participants into three groups they were refrained from regular mechanical oral hygiene measures. Subjects were asked to swish with respective mouthwash (Aloe vera mouthwash, 0.2%chlorhexidine gluconate mouthwash, or normal saline) as per therapeutic dose for 4 days. The results showed that Aloe vera mouthrinse is equally effective in reducing plaque as Chlorhexidine compared to placebo over a period of 4 days. There was a significant reduction on plaque in Aloe vera and chlorhexidine groups and no statistically significant difference was observed among them (p>0.05). Aloe vera mouthwash showed no side effects. The results of the present study indicated that Aloe vera may prove an effective mouthwash due to its ability in reducing dental plaque.

The antiplaque effect of herbal mouthwash in comparison to chlorhexidine in human gingival disease: a randomized placebo controlled clinical trial

The aim of this study was to compare the efficacy, safety, antiplaque and antigingivitis properties of a herbal mouthwash with chlorhexidine mouthwash. A double-blinded randomized clinical trial was conducted among 72 undergraduate students with age group 18-24 years. They were randomly divided into three mouthwash group with 24 participants in each group. Group A (herbal), Group B (chlorhexidine) and Group C (normal saline).The Turesky et al. 1970 plaque index and Loe and Silness 1963 gingival index was recorded. Student's t-test and one-way ANOVA were used to test the significance. A statistically highly significant difference was obtained between mouthwash B and C (p=0.00) and a significant difference between mouthwash A and C (p=0.004), showing that chlorhexidine was superior to herbal mouthwash and saline. However, there was a nonsignificant difference between mouthwash A and B (p=0.435) showing that herbal and chlorhexidine mouthwash was equally effective in reducing plaque and gingivitis. The efficacy of herbal mouthwash was equally effective in reducing plaque and gingivitis as compared to chlorhexidine mouthwash and may be considered as a good alternative. The chlorhexidine mouthwash was reported with many side effects which limits its acceptability and long-term use, whereas the presently tested herbal mouthwash had no side effects apart from mild burning sensation.

The effect of casein phosphopeptide-amorphous calcium phosphate paste and sodium fluoride mouthwash on the prevention of dentine erosion: An in vitro study.

Aim:The purpose was to compare the effect of 0.2% sodium fluoride mouthwash and casein phosphopeptide-amorphous calcium phosphate paste on prevention of dentin erosion.Materials and Methods:Buccal surfaces of 36 sound premolar teeth were ground flat and polished with abrasive discs. Half the polished surfaces were covered with tape to maintain a reference surface. Samples were randomly allocated into three groups. Group A was pretreated with tooth mousse (TM) 4 times a day for 5 days. Group B was pretreated with 0.2% sodium fluoride mouthwash 4 times a day for 5 days. Group C was considered as the control group with no pretreatment. In the next step, the samples were exposed to Coca-Cola 4 times a day for 3 days. After each erosive cycle, the samples were rinsed with deionized water and stored in artificial saliva. The surface loss was determined using profilometry.Results:The erosion in both Groups A and B was less than the control group. The surface loss in mouthwash group was significantly lower than in the control group. Erosion in TM group was more than the mouthwash group and less than the control group.Conclusion:Sodium fluoride mouthwash is more effective for prevention of dentin erosion.

Clinical evaluation of Krimidanta Pratishedha (anti-caries) activity of Triphaladi Gandusha in high risk dental caries patients.

Background:Dental caries is the most common complaint encountered in clinical practice. Virtually every adult in the world has experience of dental caries. It affects almost 80% of the population. It is now being viewed in dual perspective- “caries as a disease” and “caries as a lesion”.Aims:To evaluate the efficacy of Triphaladi Gandusha for its anti-caries activity and improvement in Oral Hygiene Index in high risk patients of dental caries and to compare the efficacy of prevalent method of mouth rinsing and classical method of Gandusha.Materials and Methods:The study was conducted in 40 patients, 20 in each Group-1 and 2. Group -1 was given prepared Triphaladi mouthwash (mouth rinse) while Group-2 was given Triphaladi Kwath for Gandusha (retention).Results:The effect of treatment was assessed by subjective and objective parameters (like salivary pH, buffering capacity and microbial count). Triphaladi Gandusha (retention) in Group - 2 provided better results in the improvement of Ruja (toothache), Dantaharsha (tooth sensitivity), Sarambha (inflammation), pH of saliva, microbial count in salivary sample. And Triphaladi Mouthwash in Group - 1 provided better results in Srava (discharge), bad breath, pH of saliva and buffering capacity of salivary sample. There was no improvement in Chidrata (cavity formation), Krishnata (discoloration) and Chaladanta (mobility) with Triphaladi Gandusha and mouthwash.Conclusion:Study concluded that although both groups were effective, but Gandusha group patients’ got better relief in subjective symptoms compared to mouthwash group.

Treatment cost development of patients undergoing remission induction chemotherapy: a pharmacoeconomic analysis before and after introduction of posaconazole prophylaxis

Prior clinical trials have demonstrated efficacy and effectiveness of posaconazole in the prophylaxis of invasive fungal diseases in high-risk patients. Controversy exists about the cost-effectiveness of this approach. We performed an analysis comparing the direct costs of posaconazole prophylaxis against polyene mouthwash (thrush) prophylaxis in patients with acute myelogenous leukaemia (AML). Data of AML patients receiving remission-induction chemotherapy were extracted from the CoCoNut (Cologne Cohort of Neutropenic Patients) database to compare hospital costs of patients before (2003-2005) and after (2006-2008) introduction of posaconazole prophylaxis. Treatment on general ward, intensive care unit (ICU), mechanical ventilation, diagnostic procedures, and all anti-infectives were calculated. Patient groups were well matched according to age, gender and duration of neutropenia. The mean costs per patient in the posaconazole group (n=76) and the polyene mouthwash group (n=81) were €21040 (95% confidence interval (CI): €18204-€23876) and €23169 (95% CI: €19402-€26937) per patient. Antifungal treatment costs were €4580 (95% CI: €3678-€5482) and €4019 (95% CI: €2825-€5214). Duration on the ICU was 2582 (95% CI: 984.1-4181.7) and 5517 (95% CI: 2206-8827.3) min. In our hospital, primary antifungal prophylaxis by posaconazole was cost-effective. There was a trend towards cost savings, which was primarily caused by a shorter overall length of stay and the less frequent ICU treatment.

Efficacy of a mouthwash containing 0.8% arginine, PVM/MA copolymer, pyrophosphates, and 0.05% sodium fluoride compared to a negative control mouthwash on dentin hypersensitivity reduction. A randomized clinical trial

ObjectiveThe objective of this eight week, single-center, two-cell, double-blind, and randomized clinical study was to evaluate the dentin hypersensitivity reduction efficacy of a mouthwash using Pro-Argin™ Mouthwash Technology containing 0.8% arginine, PVM/MA copolymer, pyrophosphates, and 0.05% sodium fluoride in an alcohol-free base (“Arginine Mouthwash”) compared to an ordinary mouthwash without any active ingredients (“Negative Control”). MethodsQualifying subjects who presented two hypersensitive teeth with a tactile hypersensitivity score between 10 and 50g of force, and an air blast hypersensitivity score of 2 or 3 participated in this study and were randomized into one of two treatment groups. Subjects brushed with the toothbrush and fluoride toothpaste provided and then rinsed with 20mL of their assigned mouthwash for 30s twice daily. Subjects refrained from eating or drinking for 30min after rinsing. Dentin hypersensitivity assessments, as well as examinations of oral hard and soft tissues, were conducted at the baseline visit and again after two weeks, four weeks and eight weeks of product use. ResultsNinety (90) subjects entered and completed the eight week study. After two weeks, four weeks and eight weeks of product use, subjects in the Arginine Mouthwash group exhibited statistically significant (p<0.05) improvements in mean tactile and air blast hypersensitivity scores as compared to the Negative Control Mouthwash. ConclusionThe results of this study support the conclusion that the Arginine Mouthwash provides a significant reduction in dentin hypersensitivity after eight weeks of product use as compared to a Negative Control mouthwash.

Prospective trial finds nystatin mouthwash effective prophylaxis for pulmonary invasive fungal infections that originate in the throat of patients with hematologic malignancies

We investigated the source of fungi in the lungs of patients with hematological malignancies who had invasive pulmonary fungal infections (IPFI). We also conducted a prospective study to evaluate the efficacy of different mouthwash solutions in preventing IPFI in patients with hematologic malignancies. In order to determine the source of fungi in the lungs of 30 patients with hematologic malignancies who had IPFI, we collected samples from sites with suspected fungal infection and used PCR and sequencing for pathogen identification. For the prospective study, we enrolled 158 patients with hematological malignancies who had IPFI and randomly assigned them to one of three mouthwash groups: 1% nystatin, 2.5% sodium bicarbonate, or normal saline. Fungal staining and incidence of IPFI, oral fungal infection, and intestinal fungal infection were evaluated. We showed that 96.7% of the fungi isolated from the throats and the lungs were identical; 76.9% of the fungi from the lungs and digestive tracts were identical and, 84.6 % of the fungi from the throats and digestive tract were identical. Patients using 1% nystatin had lower incidence of IPFI (1.6%) and fungal enteritis (1.6%) than those using sodium bicarbonate (16.3% and 14.3%) or normal saline (27.7% and 12.8%). All treatments had low incidences of oral fungal infections (0 to 4.3%). Our data showed that fungi originating from mouth and throat cause IPFI. We also showed that use of a prophylactic mouthwash containing 1% nystatin was effective in preventing IPFI in patients with hematological malignancies.

Comparative evaluation of anti-plaque efficacy of herbal and 0.2% chlorhexidine gluconate mouthwash in a 4-day plaque re-growth study

Background:Chlorhexidine gluconate mouthwash has earned eponym of gold standard to treat and/or prevent periodontal disease. However, it has been reported to have local side-effects on long-term use. To explore a herbal alternative, the present study was carried out with an aim to compare the anti-plaque efficacy of a herbal mouthwash with 0.2% chlorhexidine gluconate mouthwash and normal saline.Materials and Methods:It was an examiner-blinded, parallel designed clinical trial, in which 90 pre-clinical dental students with gingival index (GI) ≤1 were enrolled. To begin with, GI and plaque index (PI) were recorded. Then, baseline plaque scores were brought to zero by professionally cleaning the teeth with scaling and polishing. After that, randomized 3 groups were made (of 30 subjects each - after excluding the drop-outs) who were refrained from regular mechanical oral hygiene measures. Subjects were asked to swish with respective mouthwash (0.2% chlorhexidine gluconate mouthwash, herbal mouthwash, or normal saline) as per therapeutic dose for 4 days. Then, GI and PI scores were re-evaluated on 5th day by the same investigator, and the differences were compared statistically by ANOVA and Student's ‘t’-test.Results and Observations:Least post-rinsing GI and PI scores were demonstrated with 0.2% chlorhexidine gluconate mouthwash, followed by herbal mouthwash and highest scores with normal saline. The difference of post-rinsing PI scores between the chlorhexidine and herbal mouthwash groups was statistically non-significant, whereas this difference was significant between chlorhexidine and saline groups, and the difference between herbal and saline groups was non-significant. It was concluded that 0.2% chlorhexidine gluconate mouthwash remains the best anti-plaque agent. However, when socio-economic factor and/or side-effects of chlorhexidine need consideration, presently tested herbal mouthwash may be considered as a good alternative.

Increased number of micronuclei and nuclear anomalies in buccal mucosa cells from people exposed to alcohol-containing mouthwash

The aim of this study was to evaluate the effects of alcohol-containing mouthwash on the induction of micronuclei and nuclear anomalies in exfoliated buccal cells, including binucleated cells, cells with nuclear buds, and karyolitic, karyorrhectic, condensed chromatin, and pyknotic cells. Buccal mucosa cells were collected from 107 healthy participants who were divided into three groups: control subjects who did not use mouthwash (n = 33), subjects who were exposed for 30 days and two times rinsing with 30 seconds each time to alcohol-containing mouthwash (n = 38; 26% ethanol concentration); and subjects exposed to a non-alcohol-containing mouthwash (n = 36). A slide was used to collect cells from the oral mucosa from the inner lining of both cheeks. Samples were spread directly onto two separate, precleaned and precoded slides. Smears were air-dried, fixed, stained, and analyzed by microscopy for micronuclei and nuclear anomalies. Frequency of micronuclei, nuclear buds, and karyolitic, karyorrhectic, and condensed chromatin cells increased significantly (P < 0.05) in the alcohol-containing mouthwash group after mouthwash exposition, compared with both the control and the non-alcohol-containing mouthwash groups. Our results suggest that subjects exposed to alcohol-containing mouthwash exhibited an increase in frequency of micronuclei and nuclear anomalies in oral mucosal cells, which is directly related to DNA damage.
