【摘要】：研究背景:正畸治疗过程中,如患者不注意口腔卫生,会使口腔卫生下降,引起龋白斑及牙周炎。正畸治疗过程中口腔卫生的保持一直是医生与患者面对的难题,也是导致患者对正畸疗效不满意的重要因素。因此,如何促进患者在矫治过程中保持健康的口腔卫生环境显得尤为重要。在以往对正畸患者的口腔卫生宣教中,要求患者刷牙时间在3min以上,但对于具体时长下的刷牙效果未见相关研究报道。本研究探讨在系统化口腔卫生引导下,刷牙时长对青少年正畸患者口腔卫生状况的影响。目的:统计青少年正畸患者的刷牙时长,检测不同刷牙时长下各项口腔健康指数的变化,探讨正畸患者最适刷牙时长,为正畸医师临床口腔卫生宣教提供依据。方法:实验共纳入123例吉林大学口腔医院正畸科的青少年正畸患者,每月复诊时对其进行口腔卫生健康教育并发放为期一个月的《正畸矫治期间刷牙时间记录回执》要求患者记录早、中、晚三次刷牙时长,并于下个月复诊时回收进行统计。将患者的刷牙时长按其刷牙时长的众数分为1~3min、3~5min、5~7min、7~10min四组,在实验开始后的1个月、3个月和6个月复诊时,检测不同刷牙时长组患者的龈沟出血指数(sulcus bleeding index,SBI)、牙菌斑指数(plaque index,PLI)、软垢指数(debris index-simplified,DI-S)、牙釉质脱矿发病率以及釉质脱矿指数(enamel demineralization index,EDI)进行记录。进行正态性检验后,同一月份不同刷牙时长下同一指数的组间比较利用单因素方差分析,以α=0.05为检验水准。探讨不同刷牙时长对正畸患者的各项口腔卫生指标的影响。结果:1.实验开始后1、3和6个月对应不同刷牙时长的人数分布有刷牙时间逐渐增加的趋势。2.在SBI 1个月、6个月与PLI数1个月、3个月、6个月以及DI~S 3个月时,刷牙时长5~10min与1~5min相比显著降低(P0.05)。3.DI~S 1个月时,5~10min与1~3min间差异有代表性(P0.05)。4.SBI 3个月、DI~S 6个月的结果显示:刷牙时长1~3min、3~5min与5~10min各组间的指数值差异均有意义(P0.05)。5.患者在1、3、6个月复诊时,经检测刷牙时长1~3min、3~5min、5~7min、7~10min各组患者的发生釉质脱矿的比率随月份的延长出现增多趋势。6.EDI 6个月时,刷牙时长3~5min、5~7min和7~10min组与刷牙时长1~3min组间差异有统计学意义(P0.05)。结论:刷牙时长的增加可以有效改善口腔卫生状况。当刷牙时长增加到7~10min时,SBI、PLI及DI~S的结果与5~7min组比较出现减小趋势,但差异无统计学意义。提示对正畸患者进行口腔卫生宣教时,应建议刷牙时长达到5min以上,以5~7min为最佳时间。
[Abstract]:Background: during orthodontic treatment, if patients do not pay attention to oral hygiene, oral hygiene will be reduced, resulting in leukoplakia and periodontitis.The maintenance of oral hygiene in orthodontic treatment is always a difficult problem for doctors and patients and an important factor leading to patients' dissatisfaction with orthodontic effect.Therefore, how to promote the patient to maintain a healthy oral hygiene environment is particularly important.In the past oral hygiene education for orthodontic patients, patients were required to brush their teeth longer than 3min, but the effect of brushing was not reported.The purpose of this study was to investigate the effects of long time of brushing teeth on the oral hygiene status of adolescent orthodontic patients under the guidance of systematic oral hygiene.Objective: to analyze the length of tooth brushing in juvenile orthodontic patients, and to detect the changes of oral health index under different brushing periods, and to explore the optimal time of brushing teeth in orthodontic patients, so as to provide the basis for clinical oral hygiene education of orthodontists.Methods: 123 cases of juvenile orthodontic patients in Department of Orthodontics, Department of Stomatology, Jilin University, were enrolled in the experiment.The oral health education was carried out during the monthly visit and the record receipt of brushing time during orthodontic treatment was issued for one month, which required the patient to record the time of brushing early, middle and late three times, and to collect the statistics when he returned to the hospital next month.The patients were divided into four groups according to the mode of tooth brushing time: one minute, three minutes, three minutes, five minutes, five minutes, seven minutes, seven minutes and ten minutes. At the first month, three months and six months after the beginning of the experiment, the patients were visited again.The gingival sulcus bleeding index (SBI), plaque index (plaque index), soft scaling index (DI-S), enamel demineralization index (EDI), and enamel demineralization index (DAE) were measured in patients with long tooth brushing.After normality test, univariate ANOVA was used to compare the two groups with the same index at different brushing times in January, and the test level was 伪 -0. 05.To investigate the effects of different length of brushing time on the oral health indexes of orthodontic patients.The result is 1: 1.At the beginning of the experiment, the distribution of the number of teeth brushing time increased gradually at the 3rd and 6th month after brushing.At 1 month, 6 months and 1 month, 3 months, 6 months of SBI and 3 months of DI~S,Compared with 1~5min, the length of 5~10min in brushing time was significantly lower than that in 1~5min. 3. There was a significant difference between P0.05 and 1~3min at 510 minutes after 1 month of brushing. The results showed that there was significant difference in index values between the three groups of 5~10min and that of 1 3 min, 3 min, 3 min, 5 min after brushing and the difference of index values between the groups of 5~10min and P0.05 (P 0.05).The rate of enamel demineralization in each group showed an increasing trend with the extension of month. 6. There was a significant difference between 7~10min group and 1~3min group in brushing teeth for 3 minutes and 5 minutes after 6 months, and between the 7~10min group and the long 1~3min group when brushing teeth. 6. There was a significant difference between the two groups (P0.05N, P 0.05), and there was a significant difference between 7~10min group and 1~3min group (P 0.05). 6. At 6 months after brushing, the rate of enamel demineralization in each group was increased with the prolongation of month. There was a significant difference between the 7~10min group and the 1~3min group in brushing teeth.Conclusion: the increase of brushing time can effectively improve oral hygiene.When the length of brushing time increased to 7~10min, the results of SBI and DI~S decreased compared with those of 5~7min group, but the difference was not statistically significant.It is suggested that the oral health education of orthodontic patients should take longer brushing time than 5min, and 5~7min is the best time.
