【摘要】：研究背景:正畸治療過程中,如患者不注意口腔衛(wèi)生,會使口腔衛(wèi)生下降,引起齲白斑及牙周炎。正畸治療過程中口腔衛(wèi)生的保持一直是醫(yī)生與患者面對的難題,也是導(dǎo)致患者對正畸療效不滿意的重要因素。因此,如何促進(jìn)患者在矯治過程中保持健康的口腔衛(wèi)生環(huán)境顯得尤為重要。在以往對正畸患者的口腔衛(wèi)生宣教中,要求患者刷牙時間在3min以上,但對于具體時長下的刷牙效果未見相關(guān)研究報道。本研究探討在系統(tǒng)化口腔衛(wèi)生引導(dǎo)下,刷牙時長對青少年正畸患者口腔衛(wèi)生狀況的影響。目的:統(tǒng)計(jì)青少年正畸患者的刷牙時長,檢測不同刷牙時長下各項(xiàng)口腔健康指數(shù)的變化,探討正畸患者最適刷牙時長,為正畸醫(yī)師臨床口腔衛(wèi)生宣教提供依據(jù)。方法:實(shí)驗(yàn)共納入123例吉林大學(xué)口腔醫(yī)院正畸科的青少年正畸患者,每月復(fù)診時對其進(jìn)行口腔衛(wèi)生健康教育并發(fā)放為期一個月的《正畸矯治期間刷牙時間記錄回執(zhí)》要求患者記錄早、中、晚三次刷牙時長,并于下個月復(fù)診時回收進(jìn)行統(tǒng)計(jì)。將患者的刷牙時長按其刷牙時長的眾數(shù)分為1~3min、3~5min、5~7min、7~10min四組,在實(shí)驗(yàn)開始后的1個月、3個月和6個月復(fù)診時,檢測不同刷牙時長組患者的齦溝出血指數(shù)(sulcus bleeding index,SBI)、牙菌斑指數(shù)(plaque index,PLI)、軟垢指數(shù)(debris index-simplified,DI-S)、牙釉質(zhì)脫礦發(fā)病率以及釉質(zhì)脫礦指數(shù)(enamel demineralization index,EDI)進(jìn)行記錄。進(jìn)行正態(tài)性檢驗(yàn)后,同一月份不同刷牙時長下同一指數(shù)的組間比較利用單因素方差分析,以α=0.05為檢驗(yàn)水準(zhǔn)。探討不同刷牙時長對正畸患者的各項(xiàng)口腔衛(wèi)生指標(biāo)的影響。結(jié)果:1.實(shí)驗(yàn)開始后1、3和6個月對應(yīng)不同刷牙時長的人數(shù)分布有刷牙時間逐漸增加的趨勢。2.在SBI 1個月、6個月與PLI數(shù)1個月、3個月、6個月以及DI~S 3個月時,刷牙時長5~10min與1~5min相比顯著降低(P0.05)。3.DI~S 1個月時,5~10min與1~3min間差異有代表性(P0.05)。4.SBI 3個月、DI~S 6個月的結(jié)果顯示:刷牙時長1~3min、3~5min與5~10min各組間的指數(shù)值差異均有意義(P0.05)。5.患者在1、3、6個月復(fù)診時,經(jīng)檢測刷牙時長1~3min、3~5min、5~7min、7~10min各組患者的發(fā)生釉質(zhì)脫礦的比率隨月份的延長出現(xiàn)增多趨勢。6.EDI 6個月時,刷牙時長3~5min、5~7min和7~10min組與刷牙時長1~3min組間差異有統(tǒng)計(jì)學(xué)意義(P0.05)。結(jié)論:刷牙時長的增加可以有效改善口腔衛(wèi)生狀況。當(dāng)刷牙時長增加到7~10min時,SBI、PLI及DI~S的結(jié)果與5~7min組比較出現(xiàn)減小趨勢,但差異無統(tǒng)計(jì)學(xué)意義。提示對正畸患者進(jìn)行口腔衛(wèi)生宣教時,應(yīng)建議刷牙時長達(dá)到5min以上,以5~7min為最佳時間。
[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 偽 -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.
