They shuffled the deck between the study group and a control group.
The difference between the study group and the control subjects was also small.
There were no differences between the study group after propranolol administration and the control subjects.
Mast cell counts were not significantly different between the study group and the control group on day 14.
The Mann–Whitney U test was applied for comparisons between the study group and the control subjects.
Analysis of the data through the Fisher F test showed that these differences between the study group and the control group were statistically significant.
In the present study, sample size was calculated by considering a mean difference of mast cell counts between the study group and the control group.
The greatest differences between the study group and the control group were seen for the measurements between the CEJ and the base of the defect and in the width of the defect.
There are statistically significant differences between the study group and the control group in the degree of root resorption, even though the resorption seen in the study group remained within clinically acceptable limits.
Together with, there were no differences between the study group after propranolol administration and the control subjects; it is concluded that an effect on the FDG distribution in patients with a strong BAT uptake by can be disregarded in clinical praxis.
The statistically significant differences found between the study group and the control group for each site analysed appear to support the hypothesis that the bone corresponding to the extraction site undergoes remodelling and that extractive orthodontic treatment influences bone resorption to a greater extent than non-extractive orthodontic treatment.
