Periodontitis was not observed in adolescents with DM at an early stage. However, the rising levels of periodontal indices and CRP in GCF, might indicate that adolescents with DM have a higher risk of developing periodontal diseases in the future.

目的 研究牙科束缚治疗时低龄儿童及其家长的焦虑分布及不同告知方式对焦虑的缓解效果.方法 样本人群分为对照组与干预组:对照组常规口头告知束缚治疗的优缺点,干预组附加采用书面方式,告知低龄儿童牙科治疗行为管理及牙科焦虑知识.研究首次和再次治疗时患儿及家长的焦虑分布;分析此焦虑与家长自身牙科焦虑及患儿口腔相关生活指数的相关性;分组分析后续治疗过程中患儿及家长的焦虑与患儿治疗配合的改善状况,初步研究不同告知方式的焦虑缓解效果.结果 书面告知较常规口头告知对家长焦虑程度的降低有显著效果;束缚下牙科治疗患儿的焦虑与家长的焦虑及家长自身的牙科焦虑显著相关.结论 低龄儿童束缚牙科治疗时,与家长的沟通效果至关重要,应提倡书面告知,丰富告知的内容和方式,严重焦虑患儿应选择全麻等非常规行为管理方式.

目的 探寻2～6岁儿童牙科诊室行为的影响因素,建立简便易行的低龄儿童牙科诊室行为预测模型. 方法 对96例接受牙科治疗的2～6岁儿童的牙科诊室行为评估分为配合组与不配合组;问卷调查获取家长口腔健康意识、母亲牙科焦虑、儿童日常行为特点及情绪类型等资料;使用SPSS11.5软件分析组间各因素差异及与牙科诊室行为的相关程度. 结果 两组患儿年龄(4.35±0.83vs3.85±1.07)和情绪应激性(17.77±4.88vs23.23±4.76)之间差异有统计学意义(P＜0.05);治疗持续时间、幼儿园入园表现、家长对儿童口腔疾患的责任承担度与儿童口腔诊室行为均存在显著相关性(P＜0.05). 结论 通过治疗前与家长的针对性沟通可有效预测低龄儿童牙科诊室行为.

儿童的牙科行为管理问题给父母及牙医造成极大的困扰。牙科治疗过程中儿童的各种不合作表现与其特质、环境因素及牙医的操作密切相关,儿童的牙科行为管理问题涉及发展心理学、认知心理学及社会学等多学科知识。目前的相关研究较为分散,缺乏系统性的总结。现就儿童牙科行为管理问题的研究现状进行综述。

Objective To investigate the recurrence rate of the corrected crossbite in deciduous dentition and to explore the potential influencing factors. Methods Prospective controlled clinical trial was carried out in 109 patients whose deciduous crossbite had been corrected. The recurrence rate and the potential influencing factors were investigated. Results (1) The recurrence rate in the investigation was 46. 8%. (2) The potential influencing factors included occurrence of the negative ANB angle, the posterior crossbite, the improper oral habits, the retained primary teeth and the feeding method. (3) Feeding method and retained deciduous teeth might be the most powerful factors contributed to the recurrence of the crossbite in deciduous dentition. Conclusions The recurrence rate of the crossbite in deciduous dentition was high and the mechanism of recurrence was comprehensive.

PURPOSE:The aim of this study is to explore the relationship between familial oral hygiene behaviors and caries risk factors of children and to speculate the possible influential mechanism in order to predict the onset of caries accurately and thoroughly and guide the oral hygiene behaviors accordingly as well.METHODS:The behavioral variables were acquired through delivering questionnaires and then the children were grouped based on the outcome of questionnaires; the caries risk factors were made necessary transformation; the relationship between them were analyzed with SPSS 12.0 software package for independent t test, stepwise logistic analysis, correlation and regression analysis.RESULTS:(1) Familial oral hygiene behaviors did influence the caries risk factors statistically. (2) Each kind of oral hygiene behavior had its special target caries risk factor and hence speculating its mechanism was different. (3)The oral hygiene behavior of children might be the result of a complicated influence of many factors including the parents, the teachers and other facets such as the media.CONCLUSION:Besides the conventional caries risk factors, the behavioral variables should be considered to be incorporated into the caries predict model.

Objective:Explore the safety indexes of dental extraction prior to intensive chemotherapy or hemopoietic stem cell implantation in children with hematologic malignancies. Method:The study population included 65 pediatric inpatients with hematologic malignancies to be scheduled dental extraction before intensive chemotherapy or hemopoietic stem cell implantation. Examining the hemogram before extraction and the patients were monitored after extraction for bleeding,local or systemic infections, delayed wound healing and so on. Result:Of the 65 patients,all the 102 teeth were extracted successfully. Three patients suffered delayed wound heal which occurred 2 weeks later. No severe complication and deterioration occurred. Chemotherapy or stem cell transplantation was carried on successfully in 1or 2 weeks after the extraction. Conclusion:For children with hematologic malignancies,extraction is safe while the platelet count ranged from 60×109/L to 300×109/L and white blood cell count ranged from 3.0×109/L to 10.0×109/L. Transfusion of fresh blood platelet in advance is necessary if the platelet count is lower than 60×109/L and managing infection after extraction is of great importance if the white blood cell count is 1.5～3.0×109/L.
