Table 3

Mature biofilm impact assay: the percent reduction in the number of bacteria (%) compared to the control under the influence of different blood-derived products (A-PRF+ and I-PRF) from the three groups.

Groups	A-PRF+	I-PRF	values
Healthy gingiva	0.05 ± 0.09	0.07 ± 0.08	0.467
Gingivitis	0.03 ± 0.06	0.05 ± 0.05	0.169
Periodontitis	0.03 ± 0.05	0.05 ± 0.05	0.295
value	0.395	0.337

Data are presented as the mean ± SD (SD, standard deviation). Comparison between A-PRF+ and I-PRF, two-samplet test; comparison among three patient groups, one-way ANOVA. Statistical significance was set at .
