Bikini Cut Treatment for Childhood Developmental Dislocation of Hip / 实用儿科临床杂志

0.05).But in Bikini cut group,there was no intraoperative lateral femoral cutaneous nerve injury,and operation cut was so hidden and so parents were willing to accept the operation.If it was hecessary to carry out femur rotation osteotomy and internal fixation of femur,the steel plate accords with the principle of tension band,so the fixation could be stable and the fracture can easily heal up.Conclusions In the treatment of DDH,Salter pelvic osteotomy through Bikini cut has exact clinical efficacy comparing with S-P cut,and its operation cut is safe,hidden,and there is rare injury to joint function after operation.

Adhesion of oral microorganisms on dental porcelain polished and glazed / 中华口腔医学杂志

<p><b>OBJECTIVE</b>This study compared the roughness of porcelain polished or glazed surfaces and the adhesion of oral streptococcus mutans to them in vitro.</p><p><b>METHODS</b>30 porcelain samples were made. Porcelain samples in group A were polished with diamond paste. Porcelain samples were glazed in group B and were polished with Al2O3 (240#) bur in group C. Their roughness values were measured by profilometer. Standardized cell suspensions were incubated with test samples for one hour at 37 degrees C, then retained cells were counted by image analysis (percentage area of a microscopic field covered by cells).</p><p><b>RESULTS</b>Roughness values of group A, B, C were respectively (0.1987 +/- 0.057) microm, (0.1990 +/- 0.091) microm, (0.4260 +/- 0.174) microm. There was no significantly difference between group A and group B. The roughness samples in group C were significantly rougher than that in the other groups. The amount of retained cells in group A, group B, group C was respectively (15.92 +/- 4.37)%, (16.39 +/- 6.31)% and (41.48 +/- 12.1)%. There was no significant difference between the cell adhesion on porcelain surface glazed and polished, but more bacteria adhered on the porcelain surface in group C.</p><p><b>CONCLUSIONS</b>Porcelain surface polished treatment was clinically acceptable compared with its glazed. They all exhibited the least amount of bacteria adhesion. The more porcelain surface was rough, the more bacteria adhered on it.</p>
