In Vitro

Cell(human oral keratinocytes (HOKs) and human gingival epithelial cells (HGEs);4-16 μg/ μL Nicotinamide/NAM;1h

The cells were cultured in DMEM, 100 U/ mL of penicillin, and 100 mg/mL of streptomycin supplemented with 20% FBS in 5% CO2 at 37°C at a density of 5,000 cells per well in 96-well cell culture plates.  The final concentrations of NAM were 4 μg/μL, 8 μg/μL, and 16 μg/μL and a medium without NAM served as negative control.  After incubation under 5% CO2 at 37°C for 1 h, the cells were washed with sterile PBS, and 0.1 mL of the CCK-8 reagent was added to each well.  The plate was then incubated at 37°C for 3 h. Then the absorbance was measured at 562 nm using a spectrometer.  The statistics were normalized as cell via bility, and the result of the control group was set as 100%.  Each concentration was tested in three wells, and the CCK-8 assays were performed in triplicate.

The cells were cultured in DMEM supplemented with 10% FBS for 6 h and then the medium changed to SHM medium (DMEM/F12 containing 2.4 g/L NaHCO3 and L-glutamine supplemented with 5 mM HEPES (Solarbio), 30 mg/L L-proline ,0.05% BSA (Solarbio), 10 ng/ml epidermal growth factor ,insulin-transferrin-serine (ITS) , 107Mdexamethasone (Dex) , 10 mM nicotinamide (Solarbio), 1 mM ascorbic acid-2 phosphate and 1×antibiotic/antimycotic solution (Solarbio)) supplemented with YAC (10 mM Y-27632, 0.5 mM A-83-01 , 3 mM CHIR99021).

After 48 hoursinfection of human dermal broblasts, the medium was changed to hepatocyte maintenance medium (DMEM/F12 supplemented with 0.544 mg/L ZnCl2 , 0.75 mg/L ZnSO4·7H2O, 0.2 mg/L CuSO4·5H2O, 0.025 mg/L MnSO4 , 2 g/L Bovine serum albumin , 2 g/L Galactose , 0.1 g/L Ornithine , 0.03 g/L Proline , 0.61 g/L Nicotinamide (Solarbio), 1×Insulin-transferrin-sodium selenite media supplement, 40 ng/ml TGFα, 40 ng/ml EGF ,and 10μM dexamethasone ).

In Vivo

Rats(Sprague-Dawley rats;16 or 32 μg/μL Nicotinamide/NAM;局部刷药;2 min twice daily4 weeks

The infected animals were randomly assigned into four groups of seven animals: (1) 32 μg/μL NAM, (2) 16 μg/μL NAM, (3) 250 μg/mL of fluoride (as positive control), and (4) ddH2O (as negative control).  Animals in each group were treated with the compounds above topically using a camel hair brush for 2 min twice daily for 4 weeks.  The rats were fed the cariogenic Keyes 2000 diet and 5% sucrose water ad libitum during the inoculation of S. mutans and the 4-week treatment.  The rats’ weights were recorded to monitor for signs of toxicity.
