The effect of fluoride pretreatment upon root resorption after delayed replantation was
studied in beagle dogs. Upper and lower incisors were extracted and bench dried for 45
minutes. 1% Stannous fluoride solution, 2% neutral sodium fluoride gel and 1.23%
acidulated phosphate fluoride gel were used for the pre-treatment of replanted root
surface in the experimental groups. Replantation was done with no treatment in control
group. After of an experimental periods 3 weeks, animals were sacrificed by perfusion
followed by sample preparation. A histomorphometric method was applied for evaluation
of tissue reactions observed in each group under light microscope. Scanning electron
microscopic observation was done to find out any different surface topography between
groups. The results were as follows :
1. Fluoride-treated groups showed in general the better healing patterns than untreated
control group.
2. Comparions between three experimental groups revealed the general superiority of
APF-treated group over the other groups in terms of tissue healing reaction by showing
the highest frequency in uncomplicated healing pattern and surface resorption and the
lowest in inflammatory resorption, but with no statistical significance(p<.05).
3. Scanning electron micrographs shows the irregular distribution of resorption cavities
and the attached bone of variable size and shape in all groups.
4. It can be concluded that the types of fluoride did not have significant impact on the
early tissue reactions after delayed replantation under the condition of the present
experiment.
