ABSTRACT
@#Objective To understand the human resource status of the community rehabilitation management in Shanghai and provide evidence for the construction of this human resource. Methods Census institutions of community rehabilitation management in Shanghai were investigated with self-questionnaire. Results Shanghai has initially established personnel of community rehabilitation management,which contains rehabilitation coordinators and street community administrator. However, the structure and number of the personnel has yet to be improved. Conclusion Personnel building must focused on optimizing the personnel structure of rehabilitation coordinator, moderately expanding the street community administrators, filling the community rehabilitation service gap between city and urban in next stage.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effect of removing EDTA-soluble phosphate protein in dentin on the later remineralization for the purpose of better understanding of mechanism of dentin phosphate proteins on dentin mineralization.</p><p><b>METHODS</b>To remove soluble phosphate protein by EDTA dissolution, then the remineralization rate was monitored by a constant composition crystal growth technique. The results were compared with those from the normal dentin and the dentin partially demineralized by acetic acid.</p><p><b>RESULTS</b>Faster remineralization rates were found with dentin demineralized by EDTA (0.5 and 2 h) compared with normal dentin powder, while a slower rate was found with dentin demineralized by acetic acid. The increase of remineralization rate by removing phosphate protein from dentin was 100% more at 200 min after the start of the reaction.</p><p><b>CONCLUSION</b>EDTA-soluble phosphate protein in dentin has a great potential to inhibit remineralization.</p>
