摘要
目的:探讨在儿童固定正畸治疗中使用氟保护漆的效果。方法:选取2019年8月至2020年12月无锡儿童医院收治的80例需要进行固定正畸治疗的患儿,按随机数表法将其分为对照组(40例)和观察组(40例)。在两组患儿接受固定正畸治疗期间,对对照组患儿进行常规的口腔处理及护理,为观察组患儿采用氟保护漆处理牙面,然后对比两组患儿的正畸效果、咀嚼功能和临床视诊指数。结果:1)在矫正后半年、1年,两组患儿的EDI值、DD值均较矫正前显著改善,且观察组患儿的EDI值、DD值均优于对照组患儿,P<0.05。在正畸结束时,观察组患儿中存在牙釉质脱矿情况患儿的占比低于对照组患儿,P<0.05。2)矫正后,两组患儿的咬合力、咀嚼效率均较矫正前显著改善,且观察组患儿的咬合力、咀嚼效率均优于对照组患儿,P<0.05;观察组患儿的上中切牙凸距差、尖牙间宽度、上中切牙倾角、下齿槽座角均优于对照组患儿,P<0.05。3)矫正后,观察组患儿牙龈沟内细菌分布的情况优于对照组患儿,P<0.05。正畸结束时,观察组患儿的临床视诊指数优于对照组患儿,P<0.05。结论:采用氟保护漆对行固定正畸儿童的牙面进行处理,能够进一步提升其正畸效果,并可改善其口腔内部环境,提高其咀嚼功能,避免其发生牙釉质脱矿。
Objective:To investigate the effect of fluoride protector in children’s fixed orthodontic treatment.Methods:A total of 80 children who needed fixed orthodontic treatment in Wuxi Children’s Hospital from August 2019 to December 2020 were selected and divided into control group(40 cases)and observation group(40 cases)according to random number table method.During fixed orthodontic treatment,children in the control group received routine oral treatment and nursing,children in the observation group were treated with fluoroprotective paint on the tooth surface,and then compared the orthodontic effect,masticatory function and clinical visual index of children in the two groups.Results:1)In half a year and one year after correction,EDI value and DD value in the two groups were significantly improved compared with those before correction,and EDI value and DD value in the observation group were better tha n those in the control group,P<0.05.At the end of orthodont ics,the proportion of enamel demineralization in the observation group was lower than that in the control group,P<0.05.2)After correction,the bite force and chewing efficiency of the two groups were significantly improved,and the bite force and chewing efficiency of the observation group were better than those of the control group,P<0.05;In the observation group,the difference of the upper and middle incisor pitch,the width between the cusps,the Angle of the upper and middle incisor and the Angle of the lower alveolar seat were better than those in the control group,P<0.05.3)After correction,the distribution of bacteria in the gingival sulcus in the observation group was better than that in the control group,P<0.05.At the end of orthodontic,the clinical visual index of the observation group was better than that of the control group,P<0.05.Conclusion:The treatment of dental surface of children undergoing fixed orthodontic treatment with fluoride protective paint can further improve the orthodontic effect,improve the oral internal environment,improve the chewing function,and avoid enamel demineralization.
