Abstract
in English, Chinese

Objectives: This study aimed to evaluate and analyze the current situation of dentists in Guangdong pro-vince regarding the management of avulsed incisors, thereby providing a reference for making treatment strategies for avulsed incisors in the future.

Methods: A total of 712 dentists with different educational backgrounds and working conditions in Guangdong province were randomly selected to conduct an online questionnaire survey on the cognition of children with avulsed incisors from April 2022 to May 2022. The data were recorded by Excel software and statistics were analyzed on Stata/SE 15.1.

Results: A total of 712 dentists were investigated and 701 questionnaires were collected (98.46%). In addition, 65.9% of investigators came from the Department of Stomatology in a First-class Hospital or Stomatological Hospital. The results showed that the average number of avulsed teeth consulted by dentists was less than 20 per year. Although 99.7% of respondents considered normal saline as a suitable storage medium, 3.1% and 23.8% of them had a misunderstanding that the tap/alcohol could be used for root cleaning. Moreover, 93.4% was the correct selection rate of the treatment plan for processing on root surfaces before replanting by investigators. The correct selection rate of the duration using elastic fixation was only 10.7%. Meanwhile, 42.9% of investigators refused to inoculate tetanus immunoglobulin after teeth replanting. Emergency management of dental avulsion (EM) and clinical management of dental avulsion (CM) answered correctly with average scores of 14.60±11.85 and 14.48±2.67, respectively. Multivariate linear regression analysis revealed that working years were negatively correlated with EM and CM scores (P<0.05). There was a positive correlation between CM and EM scores with the number of avulsion cases treated by physicians each year (P<0.05). In terms of the EM score of dentists' learning attitude, investigators who had received enough knowledge were higher than those who had not and insufficient knowledge reserved, and the difference was statistically significant (P<0.05). The scores of investigators who thought they had a certain degree of knowledge about dental trauma were higher than those who thought they "did not understand", and the difference was statistically significant (P<0.05). In terms of CM scores, investigators who thought the knowledge of dental trauma was "very helpful" had higher scores than those who thought it was "not helpful", and the difference was statistically significant (P<0.05). The scores of the investigators who thought they had "relatively sufficient knowledge" of dental trauma were higher than those who thought they had "no knowledge" or "insufficient know-ledge", and the difference was statistically significant (P<0.05).

Conclusions: The overall accuracy of the management of avulsed incisors among dentists was low in Guangdong province. Dentists were more likely to have a higher rate of accuracy choice in treatment options for luxation injury and avulsion to enhance the prognosis of replanted teeth.

目的: 了解口腔医生关于牙齿全脱出认知的现状，并对现状进行分析，以便为今后制定全脱出牙处理策略提供参考依据。方法: 随机抽取2022年4—5月广东省内不同地区、不同学历以及工作情况的712名口腔医生对儿童牙齿全脱出的认知进行网络问卷调查，Excel软件录入数据，Stata/SE 15.1对数据进行统计分析。结果: 共发放问卷712份，回收有效问卷701份（98.46%）。65.9%受访医生来自公立三级医院口腔科或者口腔专科医院。医生平均每年接诊的牙齿全脱出病例总数少于20例。99.7%受访者知晓生理盐水是可使用的清洁介质，但仍分别有3.1%和23.8%受访者错误地认为酒精或自来水可以用来清洁根面；93.4%受访者在再植前牙根表面处理方面作出正确选择；只有10.7%的医生认为全脱出牙齿需弹性固定2~4周；42.9%受访者不同意全脱出牙齿再植后使用破伤风免疫球蛋白。牙齿全脱出应急处理（EM）回答正确的平均得分是14.60±11.85，牙齿全脱出临床处理（CM）回答正确的平均得分是14.48±2.67。多因素线性回归分析结果显示，工作年限与EM、CM得分呈负相关（P<0.05）。医师每年接诊的全脱出病例数越多，CM、EM得分越高，呈正相关（P<0.05）。在医生学习态度的EM得分方面，“接受过足够知识”的医生比“没有接受过足够知识”及“知识储备不足”的医生高，认为自己对牙外伤知识有“一定掌握程度”的医生比认为自己“不懂”的分值高，差异均有统计学意义（P<0.05）。在CM得分方面，认为牙外伤知识对日常工作“帮助很大”的医生比认为“帮助不大”的医生得分高，认为自己对牙外伤知识“掌握比较充分”的医生得分高于认为自己“不懂”或“掌握不够充分”的医生，差异均有统计学意义（P<0.05）。结论: 部分口腔医生对牙外伤应急处理方法知识储备存在不足，应提高口腔医生对完全脱出牙的应急处理理论知识和实践技能，促进脱出牙再植的预后效果。.
