A Comparison of Bacterial Growth Inhibiting Effects of Six Commercially Available Mouthrinses

Abstract

In this study the bacterial growth inhibiting effects of six commercially available mouthrinses (Hibidenta, Prodent@, Meroceta, Listerinea, Veadenta and Mendola) were determined. Hibidenta was used as a positive control. Five strains were tested (Streptococcus mutans C67, Streptococcus sanguis CH3, Veillonella alcalescens V 1, Lactobacillus acidophilus JP and Actinomyces viscosus C74), as representatives of the supragingival human microflora. The Maximal Inhibiting Dilution (MID) was measured in batch cultures for each product and strain. With respect to the positive control, Hibiden@ (containing 0.2 per cent chlorhexidine), the most effective product was MeridoP (containing 125 ppm aminefluoride 297 and 125 ppm stannous fluoride) followed by Meroceta (containing 0.05 per cent cetylpyridinium chloride), Veadenta (containing 0.03 per cent sanguinarine), Listerinea (containing phenolic compounds) and Prodento (containing 0.5 per cent sodium fluoride). Although all products have been separately reported to yield a plaque reduction in vivo, this study provides a firm basis for a comparison between products, as they were all evaluated in a similar way.

One‐year trial of the effect of rinsing with an amine fluoride‐stannous‐fluoride‐containing mouthwash on gingival index scores and salivary microbial counts in lymphoma patients receiving cytostatic drugs

“…The AmF + SnF mouthwash has been shown to have antiplaque effects in vitro and in vivo (Attenhofen et al 1989, Perdok et al 1989, Brecx et al 1990, Stosser et al 1991, but effect may not be evident in short-term studies (Ftemadzadeh et al 1989). The fact that the AmF + SnF mouthwash contains fluoride is an obvious benefit over purely antimicrobial solutions such as chlorhexidine.…”

“…Life-threatening infections can originate from orodental tissue in immunocompromised patients (Dreizen & Brown 1983, Peterson et al 1979, Bergmann 1988. Recently, oral health care in patients receiving radiotherapy to the head and neck or anticancer drugs for malignant disease has been given extra impetus in Finland.…”

Clinical effects of commercially available mouthrinses on the development of plaque, gingivitis and enamel surface free energy

“…In a previous study the bacterial growth inhibiting effects of the same collection of mouthrinses as used in this study were evaluated (Perdok et al, 1989 …”

“…4A comparison between the in vivo and in vitro effectiveness of commercially available mouthrinses. A relative in vivo effectiveness was defined with respect to Hibident® for PI, GI and PP (Eqs 7-9), whereas the in vitro effectiveness was defined according to Eq (6) (seePerdok et a!., 1989 for details). The dotted line represents the line of identity.…”
