It has been proven safe at 1-3% concentrations. The problem is that people have very different reactions to hydrogen peroxide and safe use depends on proper dilution. Studies suggest that there may be a slight decrease in gum inflammation. There also may be a slight teeth whitening effect. A summary of the population characteristics, collection methods, and number of microbial samples used for each method is outlined in Table 1 and in the participant study flowchart (Additional file 1 Fig. S4). The GCS and PERSIAN cohorts were described previously [ 17, 18]. In brief, the GCS consists of 50,045 participants aged 40–75 years, who were sampled from the urban area of Gonbad City ( n = 10,032) and surrounding rural areas ( n = 40,013) from January 2004–June 2008 [ 18]. The PERSIAN cohort has accrued approximately 165,000 participants since 2014 and is still accruing participants with the aim to include 180,000 Iranians aged 35–71 years from 18 geographic areas in Iran [ 17]. For the GCS, the inclusion criteria were comprised of not having a current or previous diagnosis of upper gastrointestinal cancer and not being a temporary resident of the area. For the PERSIAN Cohort, the inclusion criteria included being of Iranian descent, living in the study area for at least 6 months, and not having any physical or psychological disability that would prevent them from completing the enrollment process. 50 participants (25 male and 25 female) were randomly selected from Gonbad for GCS and Yazd for the PERSIAN cohort to participate in a pilot study to measure their fecal and oral microbiota. The final analytic cohort consisted of 84 individuals with a participation rate of 84%. Possible reasons for not completing the sample collection ranged from worry about the sampling ( n = 9), inability to complete the sample procedures ( n = 0), not having enough time (n = 1), or unknown ( n = 6). Basic demographic information such as age and sex were collected via questionnaire at the time of sample collection. The GCS was approved by the ethical review committees of the Digestive Disease Research Center of Tehran University Medical Science, the International Agency for Research on Cancer, and the United States National Cancer Institute. The PERSIAN Cohort received approval from the ethics committees of the Ministry of Health and Medical Education, the Digestive Disease Research Institute (Tehran University of Medical Sciences), and each participating university.

The Lancet. 2018;10152(392):1015-1035. doi:10.1016/S0140-6736(18)31310-2 When we compared the fecal samples collected by RNA later and the FOBT card, most of the microbial metrics did not differ. Similar to our results, other studies found no major differences in alpha or beta diversity metrics between FOBT cards and RNA later [ 8, 14]. While one study found similar relative abundances across common phyla [ 8], our study saw fecal samples collected by FOBT card had a significantly lower abundance of Bacteroidetes but an higher abundance of two phyla, Actinobacteria and Firmicutes (FDR < 0.001) compared to RNA later samples. In addition, we found relative abundance differences for a number of genera including Bacteroides and Bifidobacterium, but it is not possible to determine whether these were increases or decreases in these taxa (or possibly changes in other taxa) due to the relative nature of these abundances.Results from the differential relative abundance analyses at phylum and genus level for stability of oral samples are shown in Additional file 2 Table S6. Samples collected by Scope mouthwash had a higher abundance of the phylum Firmicutes (Day-0 mean 0.3354, SD 0.1157; Day-4 mean 0.3941, SD 0.1180; FDR < 0.001) but lower abundance of Proteobacteria (Day-0 mean 0.1203, SD 0.0911; Day-4 mean 0.0928, SD 0.0745; FDR < 0.001) after 4 days at room temperature. Of the 18 genera that varied significantly (i.e., FDR < 0.01) in Scope mouthwash samples, 10 genera increased in relative abundance including Bifidobacterium, F0332, Streptococcus, Peptococcus, Ruminococcaceae UCG-014, Solobacterium, Selenomonas 3, Lautropia, Pseudomonas, and an unidentified Veillonellaceae genus; 8 genera decreased in relative abundance including Rothia, Porphyromonas, Alloprevotella, Prevotella 7, Gemella, Neisseria, Aggregatibacter, and Haemophilus after 4 days at room temperature. Comparability of oral samples Essential oilscontain the "essence of" the plant's fragrance—which is characteristic of the plant from which it is derived. Their properties include antioxidant, antimicrobial, and anti-inflammatory actions. These healing oils are rapidly growing in popularity because they act as natural medicine without any side effects. Other Ingredients: Most mouthwashes contain other chemicals that help to increase shelf life or give it a desirable color. You should read the label carefully to make sure you know all of the ingredients in the type you are using. If you have an adverse reaction it could be due to one of these substances. The health claims and benefits of mouthwash vary quite a bit, so let’s see which contains what and if they live up to their claims.

Salt water is an isotonic solution, which means it contains the same salts and minerals as our body fluids and won’t irritate your gums. Chlorhexidine mouthwash may be helpful in treating gum disease; however, it is not effective for bad breath. It should always be used under guidance from your dental professional.Our study found some differences in the stability or comparability of fecal and oral samples by location. For example, stability ICCs for RNA later samples were slightly lower in Yazd samples but ICCs for FOBT cards were lower in Gonbad samples. It is unclear why the stability may differ by location or rurality, and was dependent on the collection method, but these differences highlight the importance of conducting a pilot study to optimize the best method for collecting fecal and oral collection before conducting a large prospective cohort. Previous studies have found that the gut microbiota composition differs by geographic location [ 13, 15], but it is possible that these differences could be partially related to handling characteristics such as temperature, collection methods, or processing procedures. And since it's available at a reasonable price, it’s a great budget option to add to your daily routine for oral health. Table S4 (Additional file 2) shows the differential relative abundance analyses for comparability of RNA later to FOBT cards. The relative abundance of many taxa were significantly different between RNA later and FOBT cards. For the two most abundant phyla, fecal samples collected using an FOBT card had a lower mean abundance of phylum Bacteroidetes (RNA later mean, 0.5198 SD 0.2103; FOBT cards mean 0.4004, SD 0.2016; FDR < 0.001) but a higher mean abundance of phylum Firmicutes (RNA later mean 0.3909, SD 0.1790; FOBT cards mean 0.5147 SD 0.1789; FDR < 0.001) compared to RNA later. Of the 12 genera with a mean relative abundance greater than 1% using both methods, 6 genera were higher in RNA later fecal samples, including Bacteroides, Alloprevotella, Prevotella 2, Prevotella 9, Ruminococcaceae UCG-002, and Succinivibrio, and 6 genera were higher in FOBT cards fecal samples, including Bifidobacterium, Faecalibacterium, Ruminococcus 2, Subdoligranulum, [Eubacterium] coprostanoligenes group, and an unidentified Lachnospiraceae genus. Stability of oral samples At the clinic visit, participants provided oral samples using the OMNIgene ORAL OM-505 saliva collection kit (DNAGenotek, Ontario, Canada) and Scope mouthwash (Proctor & Gamble). Participants were asked to refrain from eating and smoking at least 20 min prior to sample collection. All OMNIgene samples were collected before mouthwash samples by spitting into a pre-labeled tube until the amount of saliva reached the “fill line”. The cap was closed to release the preservative solution and mixed. Next, the participant used 10 mL of Scope mouthwash to swish for 5 s and gargle for 5 s three times each for a total of 30 s before spitting into a pre-labeled collection cup. Two 1.8 mL aliquots were created from the Scope mouthwash samples. The first was frozen immediately at -80 °C while second aliquot was kept at room temperature for 96 h (day-4) and then stored at -80 °C. After collection, OMNIgene tubes were processed according to DNAGenotek’s aliquoting protocol ( https://www.dnagenotek.com/us/pdf/PD-PR-00214.pdf). Briefly, the OMNIgene funnel cap was replaced with the standard cap and then the tube was vigorously shaken for 8 s or longer by hand. Prior to aliquoting and freezing, the sample was incubated at 50 °C for 1 h in a water bath or for 2 h in an air incubator. After incubation, two 1.0 mL aliquots were frozen immediately at -80 °C (day-0). DNA extraction and sequencing Preservatives: These prevent the growth of bacteria in the mouthwash. Common preservatives are sodium benzoate or methylparaben. They don't contribute to the action of the mouthwash.

The CloSYS Original Mouthwash strips away harsh chemicals and dyes and only leaves you with the best: a formula designed for oral health care without all the filler ingredients. For this reason, this unflavored option is perfect for people with sensitive mouths. Dry mouth is an uncomfortable condition that occurs when your salivary glands fail to produce enough saliva to keep your mouth wet. This can be hereditary or be caused by stress, medications, or smoking. Whatever the cause, this formula by Colgate can help hydrate your mouth in between brushing. According to the label, it relieves dry mouth for up to four hours. Fifty participants (25 male and 25 female) were randomly invited in Gonbad (GCS, rural area) and Yazd (PERSIAN cohort, urban area), respectively. A total of 84 individuals agreed to participate including 38 participants (76%) from Gonbad and 46 participants (92%) from Yazd. Fecal samples were collected either at the clinic or at home using a Sarstedt tube with RNA later stabilizing solution and FOBT cards. Oral samples were collected at a clinic visit using the OMNIgene oral collection kit and Scope mouthwash. At least one aliquot of each sample type was frozen immediately at − 80 °C (day-0) and one aliquot of the RNA later, FOBT cards, and Scope mouthwash samples was frozen at − 80 °C after sitting at room temperature for 4 days (day-4). Since OMNIgene ORAL samples are advertised to be stable at room temperature for up to 3 weeks, no day-4 aliquots were created. The active ingredients of Scope Outlast are cetylpyridinium chloride, domiphen bromide, and denatured alcohol. If you’re experiencing dry mouth, make sure to talk to your dentist about it. Reviewers noticed that this formula provides the relief they’ve been looking for and provides multiple hours of hydration.Reviewers love the clear formula that is free from chemical coloring dyes.
