RESUMEN
Objective To investigate the situation of nurse job burnout and the occurrence of nursing adverse events in western area of Chongqing,and to analyse the correlation between them.Methods A total of 5 hospitals in different district of west area of Chongqing was randomly selected.Then the sample of nurses meeting the inclusion and exclusion criteria was selected by random number table method,200 nurses were selected in each hospital.Multivariate logistic regression analysis was used to analyze the factors influencing the adverse events of nursing,and the structural equation model was applied to analyze the relationship between nurses job burnout and nursing adverse events.Results A total of 1 000 nurses were surveyed,and 998 valid questionnaires were collected.The rate of nurse job burnout and the incidence of nursing adverse events in the survey year were 56.41％ and 54.21％,respectively.Among nurses with job burnout,85.08 ％ occurred nursing adverse events.The increased workload,night shift,no officially budgeted post and with occupational burnout were factors affecting the incidence of nursing adverse events (OR=1.250,1.445,1.615,1.991,P＜ 0.05).The emotional exhaustion dimension of job burnout had the greatest effect on nursing adverse events (the standard partial regression coefficient was 0.31,P＜0.05),followed by the disintegration of personality (the standard partial regression coefficient was 0.29,P＜0.05),while the reduction in the sense of accomplishment had no direct effect on nursing adverse events.Conclusion In hospitals of the western area of Chongqing,the prevalence of nurse job burnout is comparatively serious,and the incidence of nursing adverse events is relatively high.The nurse job burnout and nursing adverse events might be positively correlated.

RESUMEN
<p><b>OBJECTIVE</b>This study aims to analyze the angulation of the maxillary anterior teeth relative to the alveolus to provide reference data for clinicians on the best conditions for implant placement in the esthetic zone.</p><p><b>METHODS</b>Numerous cone beam computed tomography (CBCT) images were reviewed and screened. A total of 150 maxillary images were selected by strict adherence to the defined inclusive criteria, with 75 images each from male and female patients (between the ages of 19 and 48 years at the time of CBCT scan). The maxillary anterior teeth were gathered into the following three groups for males and females: upper canines, upper lateral incisors, and upper central incisors. Then, the long axis of each qualified tooth and its corresponding alveolar process were drawn, and the angles formed by these structures were measured. The resultant data were analyzed by SPSS 19.0.</p><p><b>RESULTS</b>The long axis of the maxillary anterior teeth all inclined to the palatal side of the alveolar process. The internal angle (α) formed by the long axis of the maxillary central incisors and the long axis of the alveolar bone presented a mean value of 16.22° (range: 2.50°-28.80°) for male subjects and 15.20° (range: 2.20°-27.20°) for female subjects. The internal angle (α) of the maxillary lateral incisors exhibited a mean value of 17.50° (range: 3.80°-29.50°) for male subjects and 15.99° (range: 4.10°-33.30°) for female subjects. Finally, the internal angle (α) of the maxillary canines presented a mean value of 16.27° (range: 1.00°-31.50°) for male subjects and 15.01° (range: 3.50°-27.40°) for female subjects.</p><p><b>CONCLUSIONS</b>The long axis of the maxillary anterior teeth all inclined to the palatal side of the alveolar process. For implant placement, careful preoperative analysis and evaluation with CBCT may be beneficial for avoiding the risk factors and achieving a high probability of success in the esthetic region.</p>
