“…On the other hand, it have been studied the antibiofilm activity in bacteria from plant products or extracts that are rich in bioactive compounds (Chmit et al, 2014). Naturally, bacteria are forming biofilms which are complex communities surrounded by a exopolymer matrix.…”

“…The essential oils have been used in various applications, for example: stimulating agents, diuretics and anti-rheumatic agents, some possessing insecticidal, antifungal and antibacterial activities against pathogenic microorganisms (Chmit et al, 2014). Because its effectiveness against a considerable number of pests, their low mammalian toxicity and general availability, they have been considered as active ingredients in some botanical pesticides (Mohan et al, 2011).…”

“…The use of natural antimicrobials may conduce to control the disordered growth of oral microbiota, thus overwhelming problems caused by species resistant to conventional antimicrobials. 10,11 Natural materials have proved antibacterial action mainly because most plants used in alternative medicine are composed of flavonoids, which act on bacterial cells disrupting the cytoplasmic membrane and inhibiting the enzymatic activity. 12 Turkey is a Mediterranean country rich in medicinal and aromatic plants.…”

Amaç: Türkiye'de halk arasında yaygın olarak kullanılan bitkilerden elde edilen uçucu yağların antimikrobiyal etkilerini araştırmak ve bu etkilerden yola çıkarak ağız enfeksiyonlarında kullanılmak üzere gargara formülasyonu hazırlamaktır. Gereç ve Yöntemler: Uçucu yağlar, bitkilerden (Origanum vulgare L. spp. hirtum, Rosmarinus officinalis L., Laurus nobilis L., Salvia fruticosa Mill.) su distilasyonu metodu ile Clevenger apareyi kullanılarak elde edilmiştir. Elde edilen uçucu yağlar ve %4,5 ve %9,0 oranlarında uçucu yağların karışımını içeren gargara formülasyonlarının antimikrobiyal aktiviteleri disk difüzyon metodu ve mikrobroth dilüsyon metodu ile araştırılmıştır. Bulgular: Bu çalışmada antimikrobiyal aktivite disk difüzyon metodu ve mikrobroth dilüsyon metoduyla değerlendirilmiştir. İnhibisyon zon çaplarının 7-59 mm arasında değişkenlik gösterdiği belirlenmiştir. Uçucu yağlar, mikroorganizmalar üzerine saf olarak uygulandığında statik ve sidal etkinliğin genellikle %50 ve %50'nin üzerinde olduğu gözlenmiştir. %4,5 oranında uçucu yağ karışımı içeren F2 formülasyonunun Staphylococcus aureus ATCC 25923 üzerindeki minimum bakterisidal etkisinin %6,25 olduğu ve diğer tüm mikroorganizmalar üzerinde minimum inhibitör konsantrasyon ve minimum bakterisidal konsantrasyonunun %3,125 olduğu bulunmuştur. Uçucu yağ örneklerinin mikroorganizmalar üzerine saf olarak Objectives: The aim of this study was to prepare pharmaceutical formulations of mouthwashes and examine the antimicrobial activities of essential oils obtained from plants used traditionally in Turkey for oral infections. Materials and Methods: Essential oils were obtained from herbal drugs with water distillation method using of Clevenger apparatus. Antimicrobial capacities of mouthwash formulations containing mixture of essential oils with proportions of 4.5% and 9.0% were examined by disc diffusion method and microbroth dilution method. Results: In study, antimicrobial activity was evaluated by disc diffusion method and microbroth dilution method. The inhibition zone diameters were determined to vary between 7-59 mm. It has been observed that the static and cidal activity was generally 50% and greater than 50%, when pure essential oil samples were applied on microorganism specimens. Formulation F2 containing mixture of essential oils with proportions of 4.5%, showed 6.25% minimum bactericidal effect on Staphylococcus aureus ATCC 25923 and 3.125% the minimum inhibitor concentration and minimum bactericidal concentration on all other microorganisms. It is found that the antimicrobial effect of pure essential oil samples applied on microorganisms, was lower than mouthwashes formulations; the antimicrobial effect of F2 formulation containing mixture of essential oils with proportions of 4.5% was higher than formulation F1 containing mixture of essential oils with proportions of 9%. Conclusion:The results obtained by these methods allow us to conclude that the essential oils and prepared F1 and F2 mouthwash formulations exert activity against microorganis...

“…They are composed of a mixture of compounds as terpenoids, alcohols, aldehydes and other (Diao et al, 2013;FloresEncarnación et al, 2016c). It has been reported the bacterial antibiofilm activity from plant products or extracts rich in bioactive compounds (Chmit et al, 2014). The bacterial biofilms are communities surrounded by an exopolymer matrix adhered to surfaces (Costerton et al, 1999;Flores-Encarnación et al, 2014a).…”
