Postoperative complications of the two groups were observed after treatment. Results Dry socket incidence rate in group 1 and group 2 were 1.3% and 8.7% (P<0.01), hemorrhage incidence rate were 0.7% and 6% (P<0.05), Swelling incidence rate were 8% and 10% (P>0.05).
ResultsThe rate of the lost brackets and bands in group was 10.93%,26.67% respectively. The rate of the losted brackets and bans was 10.61%,26.05% respectively. There was no significant difference between the two groups(P>0.05).
Results There was a statistically significant difference between the groups(P<0.01). Group A showed a significantly higher retention which was 3.04 and 2.88 times as high as group B and C respectively(P<0.01). There was no significant difference between adhering and composite resin core(P>0.05).
Results After 8 weeks of arch expansion, the average width of U4-U4 and U5-U5 in removable lingual arch group was enlarged by 2.2 mm and 3.0 mm, and that in Quad-helix group by 2.3 mm and 3.5 mm, respectively, showing no significant differences between the two groups (P>0.05).
Results: Two-way ANOVA was revealed that the group of sandblasting +silica coating attained the highest shear bonding strength: 34.7±3.44 MPa (after 24 hours), 31.5±3.34 MPa (after 30 days), which was significantly different from other groups (P<0.01). While the differences among the other three groups showed no statistical significance (P>0.05).
There was no notable difference in displacement among the groups. However, displacement for group A implant with screw thread with symmetrical shape and 30 degree angle was the lowest with the value of 3.84×10-4mm and 85.61×10-4mm when loaded axially and obliquely, respectively.
Methods A randomized,stratified and clustering sampling procedure was used in 2793 of children and adolescents at the age groups of 1 to 12,15,and 18 years old in two rural communities at the township level of two provinces.
The results showed that, of 19 cases of ameloblastomas, 14 were positive (73.6%), the major positive cells were squamous epithelium cells, which suggesed that they might be precancer cell groups with tumor proliferating ability. But positive intensity was higer in a few primary embryonoid cells than in spuamous epithelium cells, it proved that some primary embrynoid cells played an important role in biologic behavor of this kind of tumor.
Considering the variability of isolates it is recommended that diagnostic PCR primers should be re-examined to ensure coverage of all BVDV-1 groups.
Interestingly, a mixed infection of two GLRaV-1 groups in the same plant was frequently detected together with a high intra-group variability in some isolates.
Bicyclo[2.2.1]heptane derivatives containing two vicinal CFC1 groups.
For the Ti-6Al-4V alloy, the control and T1 groups revealed statistically higher tensile strengths when compared to the T2 group, with no significant difference between the control and T1 groups.
Generalization of this concept toSU(2) andSU(2) × U(1) groups is carried out in such a way that the monopoles with quantized charges appear naturally and that the symmetry between the electric and magnetic phenomena is preserved.
