Table 4.

Percentage composition of the mixed-species biofilm model grown on dentine discs following “prevention” treatment.

	Percentage Composition (%) *
	S. gordonii	C. albicans	F. nucleatum	P. gingivalis
+ CONT	85.54	14.51	0.01	0.003
CHITOSAN	95.42	3.48	1.09	0.018

* Average percentage composition of each of the four microorganisms in the mixed-species biofilm model grown in THB/RPMI. Pre-grown biofilms were manually disrupted, diluted 1:5 in THB/RPMI, then treated with chitosan for a further 24 h prior to biofilm compositional analysis. Positive control biofilms received no treatment during regrowth on the biological substrates. Values representative of n = 3.
