Table 2

Biofilm inhibitory 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	0.39 ± 0.09	0.45 ± 0.10	0.053
Gingivitis	0.41 ± 0.09	0.47 ± 0.10	0.050
Periodontitis	0.42 ± 0.09	0.49 ± 0.08	0.021
value	0.572	0.575

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 .
