Figure 5 : Shows the composite numbers of all bacterial species determined by DNA analysis that are present following conventional mechanical treatment and homecare which are evident before treatment.

These numbers can be compared to during and after direct medication treatment. The number of Gram negative obligate anaerobes was found to decrease as the number of Gram positive anaerobes and all facultative and aerobic bacteria increased during treatment. The total numbers of bacterial species decreased during the treatment and maintenance phase when compared to the before treatment numbers.
