Mouthwash is a product used as an adjunct to oral hygiene practices as an antiseptic and antiplaque and antimicrobial agent. The awareness of using mouthwash solution is so limited worldwide. And maybe there’s effect of mouthwash on commensal flora. The aim of this study is to measure the effect of using Mouthwash solution on commensal flora of the oral cavity. In this study, we determined three groups, the first group is considered as a basic group where Female students are not using any mouthwash, the second group used mouthwash twice daily for two weeks, group number three used mouthwash twice weekly. We take cytological sample scraping from oral cavity. All the cytological sections of all groups stained with Papanicolaou stain and examined the slides under the microscope. The study came out with the following results: The basic group that did not use any mouthwash remained unchanged, while the second group, who used mouthwash twice daily, showed a clear epithelial tissue for any bacteria and a clear background. Group number three, who used mouthwash twice a week, showed countable bacteria in epithelial tissue with a clear background. Finally, the study concluded: Cosmetic mouthwash solution has a bad effect on commensal flora if you over used it and leads to killing all your normal flora in oral cavity as much as therapeutic mouthwash will do.展开更多

The objective was to improve the function of marine Arthrobacter oxydans KQ11 dextranase mouthwash(designed and developed by our laboratory). The experiment was conducted in a three-level, four-variable central composite design to determine the best combination of Zn SO_4, lysozyme, citric acid and chitosan. The optimized antibacterial agents were 2.16 g/L Zn SO_4, 14 g/L lysozyme, 4.5 g/L citric acid and 5 g/L chitosan. The biofilm formation inhibition reached 84.49%. In addition, microscopic observation of the biofilm was performed using scanning electron microscopy and confocal laser scanning microscopy. The optimized formula was tested in marine dextranase Arthrobacter oxydans KQ11 mouthwash and enhanced the inhibition of S. mutans. This work may be promoted for the design and development of future marine dextranase oral care products.展开更多

Sixty patients newly admitted to internal and trauma Intensive Care Units of the two educational hospitals of Sanandaj city affiliated with Kurdistan University of Medical Sciences were selected by convenience sampling and allocated to two groups of 30 patients using random blocks design. In each group,the mouthwash was applied twice a day for four consecutive days. Swab samples were taken from the mouth and throat of all patients three times a day(pre-intervention, two days, and four days after the intervention) and then the samples were transferred onto the blood agar and eosin methylene blue(EMB) culture plates and investigated for bacterial growth and colonization after 24-48 h.RESULTS: The findings showed that oropharyngeal colonization was not significantly different between the two groups, pre-intervention, two days,and four days after the intervention(P > 0.05). Rinsing with honey mouthwash 12.5% led to the inhibition of Staphylococcus aureus and Pseudomonas aeruginosa on the fourth day of the intervention in all samples.CONCLUSION: None of the studied solutions contributed to the reduction of oropharyngeal bacterial colonization. It seems that the growth inhibition of Staphylococcus aureus and Pseudomonas aeruginosa by the honey 12.5% mouthwash in mechanically-ventilated patients need further investigation.展开更多

Treatment comprised of application of tobacco or placebo mouthwash(10 m L 3 times a day) for 5 days. Clinical evaluation included pain level using a visual analog scale and ulcer size on days 1, 3, and 5 were measured. Adverse effects after mouthwash application were recorded, and the oral mucosa was examined by the investigator at each visit.RESULTS: A total of 54 subjects with the mean age(38 ± 10) years fulfilled the study. No minor and major adverse effects were observed. In the treatment group, ulcer pain score was decreased by 79.2%and 93.8% and ulcer size was reduced by 69.1%and 92.2%(days 3 and 5, respectively), which was significantly greater than the control group(P <0.01).CONCLUSION: The decoction prepared with of Nicotiana tabacum leaves, used as mouthwash are well-tolerated and safe, and can be used for the management of recurrent aphthous.展开更多
