CARVALHO, Monize Ferreira Figueiredo de et al. Assessment of sodium fluoride 2% as a new method of disinfecting extracted human teeth. RGO, Rev. gaúch. odontol. (Online) [online]. 2016, vol.64, n.4, pp. 432-433. ISSN 1981-8637.

Objective Investigate the action of sodium fluoride 2% as a new method of disinfecting/sterilizing extracted human teeth, using E. faecalis. Methods The survival rate of E. faecalis ATCC 29212 was assessed, in terms of absorbance from the culture media, using a spectrophotometer. The sterilization assessment was carried out in the following groups: Group I (GI) - control; GII - autoclave; GIII - sodium fluoride seven days; GIV - sodium fluoride 14 days. Results When using the autoclave and sodium fluoride solution (2%), the quantity of bacteria reduced significantly when compared to the control group (p <0.001). Statistically significant differences were also found when the experimental groups were compared with each other (p < 0.001). Conclusion The results of the present study suggest that sodium fluoride 2% solution can be considered a new disinfection method based on its capacity to reduce the load of E. faecalis.
