An oral cavity hygiene plays a key role in prophylactic and therapeutic measures to prevent pathological changes caused by different viruses, bacteria, fungi and protozoa. It is important to maintain proper oral hygiene and assist the removal of potent pathogens; use of the mouthrinses can be one of method providing to these goal. The purpose of this study was to investigate the effects of selected mouthrinses on the standard strains of Candida presented in the oral cavity. Eight reference strains of fungi were investigated: C. albicans (CBS 2312), C. albicans (L 45), C. albicans (ATCC 24433), C. dubliniensis (CBS 7987), C. glabrata (CBS 862), C. krusei (CBS 573), C. parapsilosis (CBS 10947) and C. tropicalis (CBS 2424). Thirteen mouthrinses were used in the study, including pure chlorhexidine (CHX), and 12 commercially available varieties: Azulan, Colgate Plax Complete Care Sensitive, Corsodyl 0,2%, Curasept ADS 205, Dentosept, Dentosept A, Eludril Classic, Listerine Total care, Octenidol, Oral-B Pro-Expert Clinic Line, Sylveco and Tinctura salviae. The present study used a qualitative diffusion in agar gel-well plate method to evaluated the antifungal properties of mouthrinses. Among the 12 commercially available mouthrinses examined in the study, the following were not found to show antifungal activity: Azulan, Dentosept, Eludril Classic, Listerine Total care, Tinctura salviae. The largest inhibition zones were produced by Dentosept, Chlorhexidine and Colgate. The smallest inhibition zones were produced by Octenidol and Curasept. With regard to mouthwash type, statistically significant differences in growth inhibition zone diameter were found between the following pairs of fungi: C. albicans and C. krusei for Colgate without dilution and with 1:2 dilution; C. albicans and C. glabrata for Corsodryl without dilution and with 1:2 dilution; C. albicans and C. dubliniensis for Dentosept A without dilution; C. glabrata and C. parapsilosis with 1:2 dilution; C. dubliniensis and C. tropicalis for Sylveco without dilution, 1:2 dilution and 1:4 dilution; C. dubliniensis and C. parapsilosis for Sylveco without dilution, 1:2 dilution and 1:4 dilution. The lowest MIC values calculated from the Iinear regression equation, indicating the strongest potential activity, were obtained for Dentosept A, followed by chlorhexidine; the lowest activity, was calculated for Curasept and for Octenidol. Some of the tested mouthrinses have antimycotic properties at commercially available concentrations. In spite of the fact that chlorhexidine is thought to be the gold standard for mouthrinse use, Dentosept has stronger antimycotic activity and acts on a wider spectrum of fungi species. Chlorhexidine and Colgate do not appear to act against C. tropicalis, neither does Curaspet against C.dubliniensis; therefore, the determination of the fungus species is necessary.

Protozoa, such as Trichomonas tenax, Entamoeba gingivalis and Leishmania braziliensis, may be present in the mouth but their role in the pathophysiology of oral diseases is not clear yet. The use of various types of mouthrinses plays an important role in maintaining proper oral hygiene and in removing some of the microbial components from the oral cavity. The purpose of this study was to investigate the effects of selected mouthrinses on the reference strains of Trichomonas tenax and Entamoeba gingivalis which can be a part of the oral cavity microbiota. Two standard strains Trichomonas tenax (ATCC 30207) and Entamoeba gingivalis (ATCC 30927) were used and metronidazole as a drug used in the treatment of infections caused by protozoa as well as fourteen agents used as mouthwashes were tested, with two pure compounds acting as mouthrinse ingredients, i.e. 20% benzocaine and 0.2% chlorhexidine, as well as 12 commercially-available formulas: Azulan, Colgate Plax Complete Care Sensitive, Corsodyl 0.2%, Curasept ADS 205, Dentosept, Dentosept A, Eludril Classic, Listerine Total Care, Octenidol, Oral-B Pro-Expert Clinic Line, Sylveco and Tinctura salviae. The protozoonicidal activity of the preparations was evaluated on the basis of the ratio of dead to living ratios after incubation in an incubator (37°C) for 1, 10 and 30 min. Protozoa were counted in the Bürker chamber in each case up to 100 cells in an optical microscope (over 400×). The criterion for the death of protozoa was the lack of movement and changes in the shape and characteristics of cell disintegration. The curves of activity were obtained after experiments conducted for 5–7 different solutions of each preparation. On the basis of the curves, the solution killing 50% of the population (CL₅₀) was calculated. All mouthrinses tested in this work in their undiluted form acted lethally on both protozoa. Benzocaine, used as a local anesthetic, has etiotropic properties which can be useful for supporting antiprotozoal treatment. Chlorhexidine confirmed its high efficiency in the eradication of potentially pathogenic protozoa. The use of mouthrinses is an important complement for other procedures intended to maintain correct oral hygiene.
