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.

SiO2/TiO2 nano-hybrid particles were successfully prepared by hydrothermal method by using titanium tetrafluoride (TiF4) as the titanium source, silicon dioxide as template. The factors of hydrothermal temperature and hydrothermal time on the morphologies and photocatalytic activity of SiO2/TiO2 nano-spheres were systematically discussed in this paper. The structures and properties of the SiO2/TiO2 nano-hybrid particles were studied by some techniques such as SEM, TEM, XRD and BET analysis. The results indicated that TiO2 prepared by hydrothermal method were anatase crystal, and in the form of polycrystalline. The formation mechanism of SiO2/TiO2 nano-hybrid particles was also discussed.
