SummaryThe viable counts, pH and production of lactic acid were determined for Lactobacillus lactis, L. helveticus and Streptococcus thermophilus after 0, 5 and 24 h anaerobic incubation at 44 °C in skim milk containing 0, 3, 5 or 7μg cadmium (Cd)/l. In skim milk containing 7μg Cd/l, a noticeable decrease in lactic acid production and inhibition of the decrease in pH was observed for all three strains after 24 h, although there was only a slight inhibition of growth. With 3 and 5μg Cd/l, there was only a slight inhibition in the decrease in pH. In addition, with 3 μg Cd/l some evidence of stimulation of lactic acid production was found. The inhibitory effect of low Cd concentrations on lactic acid bacteria may give rise to problems in the dairy industry.

AbstractThis in vitro study evaluated the protective effect of titanium tetrafluoride (TiF4) varnish and silver diamine fluoride (SDF) solution on the radiation-induced dentin caries. Bovine root dentin samples were irradiated (70 Gy) and treated as follows: (6 h): 4% TiF4 varnish; 5.42% NaF varnish; 30% SDF solution; placebo varnish; or untreated (negative control). Microcosm biofilm was produced from human dental biofilm (from patients with head-neck cancer) mixed with McBain saliva for the first 8 h. After 16 h and from day 2 to day 5, McBain saliva (0.2% sucrose) was replaced daily (37 °C, 5% CO2) (biological triplicate). Demineralization was quantified by transverse microradiography (TMR), while biofilm was analyzed by using viability, colony-forming units (CFU) counting and lactic acid production assays. The data were statistically analyzed by ANOVA (p < 0.05). TiF4 and SDF were able to reduce mineral loss compared to placebo and the negative control. TiF4 and SDF significantly reduced the biofilm viability compared to negative control. TiF4 significantly reduced the CFU count of total microorganism, while only SDF affected total streptococci and mutans streptococci counts. The varnishes induced a reduction in lactic acid production compared to the negative control. TiF4 and SDF may be good alternatives to control the development of radiation-induced dentin caries.
