Effectiveness of a new generation anticavity mouthwash on Streptococcus mutans and Lactobacillus acidophilus count: A microbiological study

Abstract

Background Dental caries is one of the most widespread disease. CariFree CTx4 treatment rinse mouthwash is designed to treat the cavity-causing plaque biofilm, reduce the overpopulation of cavity-causing bacteria, and neutralize decaycausing acids with patent-pending pH + technology. Aim: The aim of the present study was to assess and compare the antibacterial effect of a new generation anticavity mouthwash (CariFree CTx4 treatment rinse) with that of a 0.2% chlorhexidine mouthwash (Clohex), 0.05% sodium fluoride mouthwash (Colgate Plax Complete Care), 2% povidone iodine mouthwash (Betadine gargle and mouthwash) against Streptococcus mutans and Lactobacillus acidophilus. Materials and methods: Strains of S. mutans and L. acidophilus were grown on suitable media and the inhibitory effect of the test substances was noted by disk diffusion method and Agar well diffusion method. The results obtained were then subjected to statistical analysis. Result: Efficacy of CTx4 treatment rinse mouthwash was less than chlorhexidine for both S. mutans and L. acidophilus whereas its efficacy was comparable to that of povidone iodine and sodium fluoride mouthwash for S. mutans and to that of sodium fluoride for L. acidophilus. Conclusion: It was concluded that chlorhexidine is still the best mouthwash available.
