Objective To study the differences in the inclination of lower incisors among the female patients with beautiful profiles in different vertical skeletal types so as to provide the clinical treatment design for a certain guiding. Methods 137 cephalometric films of female patients with beautiful profiles were selected and divided into three groups based on the vertical facial types(∠SNMP):small degree(n = 31),average degree(n = 89) and larger degree groups(n=17). The angles of∠L1/MP and∠L1/A-Pog were measured and treated with covari-ance analysis for detecting the differences between the groups. Results The index of L1-MP(°)was the smallest in the larger degree group,the largest in the small degree group and average in the average group,with significant differences between the three groups(F = 17.38,P < 0.001). There was no significant differences in ∠L1/A-Pog (°)(F=2.61,P>0.05). Conclusion Lower incisors have compensatory inclined lingually in the group of higher mandible angle,but labially in the group of lower mandible angle.

Objective: This study aims to explore the effect of practice on the triage and acuity scale in the emergency department of Stomatological Hospital. Methods : 150 emergency patients admitted to the emergency department from April 2016 to July 2016 were randomly selected as the control group before the implementation of graded district diagnosis and treatment, and 150 emergency patients admitted from August 2016 to November 2016 were selected as the observation group after the implementation of graded diagnosis and treatment. The control group was treated with the traditional nursing treatment mode, and the observation group adopted the triage and acuity scale mode. The efficiency of treatment for the patients and the degree of satisfaction of the patients in terms of the nursing work was compared between the two groups (waiting time, checkup time, start treatment time). Results: A comparison of the patients in the observation group and control group showed that the waiting time (min)(25.63 ± 8.75 vs. 35.57 ± 10.60, t = -8.52, P < 0.001), the time of accepting examination (min)(24.80 ± 7.90 vs. 39.23 ± 12.42, t = -12.01, P < 0.001) and the starting time of treatment （min）(28.67 ± 9.37 vs. 40.47 ± 10.86, t = -10.08, P < 0.001) were significantly lower in the observation group than the control group (P < 0.05). The degree of satisfaction with the nursing work for the patients in the observation group (96.67%) was higher than that of the control group (85.33%), and this difference was statistically significant (χ2=17.647, P=0.001). Conclusion The application of a triage and acuity scale in the diagnosis and treatment of stomatological emergency patients according to the severity and urgency of disease can ensure the priority of treatment in critically ill patients, the safe and efficient performance of emergency work, and improvements to the efficiency and quality of emergency medical services.
