Biovolumes (µm³/µm²) of the biofilms of S. mutans UA159 formed on saliva-coated surfaces in the presence and absence of UDMA, as assayed using a LIVE-or-DIE^TM viability/cytotoxicity kit. DMSO was used as a vehicle for UDMA, and cells grown without UDMA (2% DMSO) were used as the control. The biovolume was calculated based on five randomly selected areas of each biofilm after 24 h biofilm development.

Carbohydrate Source	2% DMSO		UDMA
