This study assessed the effect of Pdx (NaHCOIt is well established that the individual brushing technique influence plaque removal [The composition of dental plaque depends on a variety of competing microbial-microbial and host-microbial interactions [Ozaki et al. [The present study applied both PlI [Akwagyiram et al. [Recently, Tascieri et al. [To our knowledge, Pdx sold in Europe does not contain SnF. However, during research it was discovered that SnF is an ingredient in Pdx sold in USA. Dentifrices containing SnF have demonstrated to have statistically significant better efficacy compared to placebo in regards of chemical biofilm control [Pratten et al. [The present study had some limitations. There was a limited sample size. The experimental gingivitis model was used and this justifies the short observation time, which is more a strength than a limitation since it allows the assessment of the true anti-plaque effect. Weekly assessment of compliance by directly contacting the participants could have been further assured by collecting the dentifrice tubes following day 21 for evaluation of compliance.It is possible that placing and removing the individual fitted tray affect the amount of plaque, but since this will be the same for test and control; it will most likely not affect the results. We did not do microbial testing of the dental plaque, thus cannot say anything about potential changes in the bacterial plaque composition, but based on our results we did not find any statistically significant differences in any of the measured parameters.
