Abstract
Background and aims. Anticariogenic effects of different mouthrinses have been shown previously. In this in vitro study the anticariogenic effects of polyphenol extract of green tea with 0.05% fluoride, 0.2% chlorhexidine and fluoride-chlorhexidine were compared.Materials and methods. This in vitro study was performed on 50 maxillary premolars in 5 groups: 1) normal saline; 2) a 10% solution of green tea polyphenol extract; 3) 0.05% fluoride; 4) 0.2% chlorhexidine; and 5) fluoride-chlorhexidine. Each tooth was placed in a tube which contained a cariogenic solution. Every day the teeth were washed (depending on the experimental groups) with 5 mL of mouthrinse solution. The depth of the caries was measured under a polarized light microscope. Data were analyzed using SPSS 13.0 with Kolmogorov-Smirnov, one-way ANOVA and Tukey tests.Results. The mean and standard deviation (in µm) of caries depth were 194±16.43, 175±17.94, 142±9.34, 155±13.27, and 144±8.57 in groups 1 to 5, respectively, with significant differences between the groups (P<0.001). Tukey test showed that although there was no significant difference in the depth of caries in groups 1 and 2 (P>0.001), they were significantlyless than those in groups 3 to 5 (P<0.001). There was no significant difference between decay depth of groups 3, 4 and 5 (P>0.001).Conclusion. The anticariogenic effect of fluoride-chlorhexidine was the highest among the groups. Although green tea showed higher cariostatic effects than normal saline, in comparison with other mouthrinses, it is less effective. More re-search is strongly recommended for clinical use of green tea as an anticariogenic agent.
Highlights
One of the most common chronic diseases in the world, dental caries, is an infectious diseaseJODDD, Vol 9, No 1 Winter 2015 caused by the colonization of bacteria, which begins with the decalcification of the non-organic part of the tooth and is followed by the decay of the organic matrix
Polyphenolic compounds isolated from green tea suppress the activities of oral bacteria such as Streptococcus mutans and Prevottella gingivalis, which are strongly implicated in the development of dental caries and periodontal deseases.[8,9]
Since the polyphenol compounds in green tea have been identified as antibacterial compounds,[25] we attempted in this study to compare the anticariogenic effect of green tea polyphenol extract with that of mouthrinses available on Washing solution Normal saline Green tea Fluoride Chlorhexidine Fluoride- chlorhexidine Total
