[Abstract]:Objective: the purpose of this experiment was to study the antibacterial properties and duration of the pure titanium grinding tablets soaked with different concentrations of organosilicon quaternary ammonium salt solution. Methods: after 1 antibacterial experiments were finished, the 120 titanium slices were randomly divided into six groups, A, B, C, D, E, F, and each group of 20 pieces of.6 were randomly divided into four subgroups of 1,2,3,4, and were randomly divided into four subgroups of 1,2,3,4. Each group of 5 groups of.A groups were soaked in 1% concentration of silicone quaternary ammonium salt solution; group B: 5% concentration of silicone quaternary ammonium salt solution; group C: 10% concentration organosilicon quaternary ammonium salt solution; D group: 30% concentration organosilicon quaternary ammonium salt solution; E group: 60% concentration of silicon quaternary ammonium salt solution; F group: steeped distilled water soaked in sterilized water. The treatment time of the four subgroups was 30 min, 2 group 60 min, 3 group 120 min. 4 groups of 240min. were removed and rinsed into the sterile distilled water to rinse 10min, then put out, and then put into the sterile 24 hole cell culture plate after natural drying. The standard strain ATCC49619 of Streptococcus pneumoniae was resuscitation with 1640 liquid medium, and the turbidimeter adjusted the bacterial liquid. The concentration is 0.5M., the samples of different groups are soaked in 1ml bacteria suspension, and the specimens are incubated in the constant temperature box of 37 C, and the specimens are extracted by 24h., then the floating bacteria are cleaned by the sterilization distilled water. Then the specimens are put into the 3ml1640 liquid medium, and the oscillator oscillates 1min in the oscillator, and the Ye Tipei's foster group is transferred to the turbid special tube, and the mixture is used evenly after the use. The bacterial liquid concentration was counted by the turbidimeter. The aseptic 1640 liquid medium was used as the blank control. The results of the experiment were statistically analyzed. The results showed that 1% organosilicon quaternary ammonium salt soaked in 120min group was the lowest, and the best antibacterial performance group. This immersion method was used to test the antibacterial duration of the following experimental.2 for the selection of pure titanium specimen 30 G, H, I, J, K five groups, each group of 6 samples: G group after degreasing sterilization with 1% organosilicon quaternary ammonium salt soak 120min, immerse the specimen in 5 centigrade and 55 C in the constant temperature water bath respectively, respectively, after 0 times to take out, the H group after degreasing sterilization with 1% organosilicon quaternary ammonium salt soak 120min, immerse the test parts at 5 and 55 C constant temperature water The 30s was soaked in the bath for 2500 times, and the I group was soaked with 1% organosilicon quaternary ammonium salt for 120min after degreasing and sterilizing. The samples were soaked in 5 C and 55 C in the constant temperature water bath respectively for 30s, and then taken out for 5000 times. The j group was soaked with 1% organosilicon quaternary ammonium salt after degreasing and sterilizing, and the specimens were immersed in 5 and 55 degrees centigrade. 30s was soaked in the warm water bath and removed for 10000 times. The K group was treated with only degreasing sterilization and distilled water to soak. The treated samples were put into the 0.5m suspension of 1ml respectively. The incubators were incubated at 37 degrees centigrade for 24h, and the specimens were removed, and the floating bacteria were cleaned by sterilized distilled water, and then the specimens were put into the liquid medium of 3ml1640. The liquid medium was transferred to 1min, the liquid medium was transferred to the turbidimetric special tube, and the concentration of the bacteria was counted using the turbidimeter. The sterile 1640 liquid medium was still used as the blank control.3 data processing, and the data of this study were processed by the SPSS13.0 software, and the non parameter test of kruskal-wallish was selected. Analysis of antibacterial properties, LSD test for 22 comparison, P0.05 representative of statistical significance. Select the dunnett-t test for the antibacterial time experimental data processing, P0.05 representative of statistical significance. Results: 1 the main effect of different concentrations of antimicrobial determination, the main effect is different, P0.05; but for different treatment time There is no statistical significance between the main effect of P0.05 and the interaction between the two. The results of the analysis and comparison of the concentration factors of p0.05. show that there are no differences between the a group and the B group in the six groups of data of a, B, C, D, e and F, and there is no difference between the C group and the D group and the other two groups. The difference P0.05 shows that the treatment of a group 1% concentration can make pure titanium produce antibacterial.2 antibacterial duration determination result G group, H group and I group are lower than K group, the difference has statistical difference, P0.05, J group and K group have no statistical difference, p0.05. conclusion: 1 silicone quaternary ammonium salt solution after pure titanium, can make pure titanium. The optimum treatment concentration is 1%, the most suitable treatment time is 120min.2 after 1% organosilicon quaternary ammonium salt solution of pure titanium 120min, its antibacterial properties can be maintained for about 6 months.
