RESUMO
PURPOSEï¼To explore the clinical effect of continuous oral health education on elderly patients with chronic periodontitis treated with dual wavelength lasers. METHODS: The clinical data of 150 elderly patients with chronic periodontitis treated with dual-wavelength laser in Shanghai Ninth People's Hospital between March 2016 and March 2018 were analyzed and divided into 2 groups according to the different intervention plans applied. Seventy-five cases receiving routine oral hygiene education were taken as the control group, and the other 75 patients receiving continuous oral health education were set as the experimental group. Oral behavior, gingival index and dental plaque index in the two groups were analyzed and compared using SPSS 21.0 software package. RESULTS: The proportions of patients with correct brushing, taking regular oral examination and maintenance, and keeping good oral habits in the experimental were 97.33%, 93.33% and 92.00%, respectively, which were significantly higher than those in the control group (P<0.05). The gingival index and dental plaque index 3 and 6 months after intervention were (1.24±0.14) and (1.08±0.10), (1.50±0.10) and (1.69±0.26), respectively in the experimental group, which were significantly lower than those in the control group (P<0.05). CONCLUSIONS: For elderly patients with chronic periodontitis treated with dual-wavelength laser therapy, application of continuous oral health education can improve their oral behavior and periodontal status, therefore is worthwhile to be popularized in clinical application.

PURPOSE: To investigate the effects of psychological nursing on anxiety of patients during extraction of impacted teeth. METHODS: Seventy patients who required impacted tooth extraction were randomly divided into intervention group (n=35) and control group (n=35). In the intervention group, psychological nursing was performed by special nurses before, during and after the surgical procedure; In the control group, patients were informed the general knowledge of the routine treatment and care. Anxiety was evaluate with anxiety scale at the end of surgical procedure. The data was analyzed with SPSS 13.0 software package for X2 test. RESULTS: The number of patients with anxiety in the intervention group was significantly reduced compared with the control. The difference was statistically significant (P<0.05). CONCLUSIONS: Psychological nursing assists to relieve anxiety of patients during impacted teeth removal.

INTRODUCTION: In previous studies, we found that hypoxia promoted the mineralization of dental pulp cells (DPCs). However, the clinical application of hypoxia as a therapy is questionable or unfeasible. Deferoxamine (DFO), a medication for iron overload, has also been shown to induce hypoxia. The purpose of this study was to investigate the effects of DFO on the repair ability of DPCs. METHODS: DPCs were obtained by using a tissue explant technique in vitro and were treated with different concentrations of DFO or hypoxia culture for 2 days. The viability, proliferation, migration, and odontogenic differentiation of DPCs were assayed and analyzed. The expression of hypoxia-inducible factor 1-alpha (HIF-1α) was assessed through Western blotting. RESULTS: Ten micromolars of DFO enhanced the expression of HIF-1α similarly to hypoxia and did not affect the viability of DPCs for 2 days. Furthermore, the proliferation, migration, and odontogenic differentiation of DPCs were promoted by DFO. CONCLUSIONS: These results suggest that DFO might improve the repair ability of DPCs by HIF-1α.
