The purpose of this study was to confirm the tooth cleaning effect by comparing the effect of removing the tooth surface bacterial film according to the use of a dentifrice.
Using each tool, wipe a total of 3 times from the back of the tongue to the front and instruct all experimenters to gently rinse their mouth with water.
After obtaining the average of absorbance measured in each case, paired t-test compares the effects of removing lingual bacterial membranes before and after the use of the tongue debris, and compares the means between groups with on-way ANOVA and post-test.
The average of the group using the dentifrice was 10.3, and the group that did not use the dentifrice was 11.1, showing similar removal rates. Even if the subjects brush their teeth without a dentifrice, it was found that the removal of tooth surface bacterial membrane was effective. Therefore, it is judged that tooth brushing that does not contain a dentifrice has the same effect of removing tooth surface bacteria as using a dentifrice.
In the follow-up study, it is necessary to analyze the types and characteristics of dentifrice, determine the exact method of brushing teeth, and set a certain time and intensity to derive and analyze more specific results.
