  1. Ascertained implication was assessed by establishing quality and quantity parameters to support the suggested effect of SMFP. The spectrophotometer measured parameters: concentration and purity corresponded to the degree of toothpaste remains in the toothbrush. Greenish coloured sample “a” presented the highest amount of DNA concentration (371 μg/ml) under OD260 (nm) Absorbance while in return, purity measured the lowest level (1.25) of other samples signifying a lost DNA intactness by SMFP. Sample “a” shows that the SMFP effect increases as the amount of compounded toothpaste increases
