【摘要】：目的:随着人们生活条件的改善,人们对美的追求越来越高,因此,关注错颌畸形的人也日益增多,越来越多的患者选择接受固定正畸治疗。牙龈炎是固定矫治过程中常见的并发症之一,对患者进行常规口腔卫生宣教及牙周治疗效果往往不够尽善尽美。有研究表明,低强度激光(1ow level laser,LLL)具有生物调节作用,能够减轻组织炎症反应,促进伤口愈合。本研究通过临床实验,探讨低强度激光治疗(1ow level laser therapy,LLLT)对固定正畸牙龈炎的疗效,为口腔临床工作者对固定正畸牙龈炎的治疗提供参考,为LLL在正畸临床上的应用提供理论依据。方法:选取固定正畸牙龈炎患者20例,年龄12-18岁(男12例,女8例),平均年龄15.2岁。实验前对每位患者进行常规的口腔卫生宣教及牙周洁治,彻底清除牙石、软垢。牙周基础治疗一个周后,每位患者选择31、32、41、42四颗牙为指数牙,左、右侧随机分为实验组和对照组,测量两组的菌斑指数(Plaque index,PLI)、牙龈指数(Gingival index,GI)、出血指数(Blooding index,BI)、探诊深度(probing depth,PD)四个牙周临床指标,并检测两组龈沟液中IL-1β的浓度,其数据定为“治疗前”。实验组牙龈给予低强度激光治疗(650nm,25mw),1次/日,连照3天;对照组不作处理。一周后,再次测量实验组和对照组四种牙周临床指标及龈沟液中IL-1β的浓度,其数据定为“治疗后”。所有检查由同一医师完成。比较治疗前、后各项指标并进行统计学处理。结果:1.牙周临床指标的比较:实验组与对照组PLI、GI、BI、PD值治疗前比较差异均无统计学意义,治疗后四项指标,实验组均明显低于对照组,差异有统计学意义(p0.05)。2.龈沟液IL-1β浓度的比较:治疗前实验组与对照组龈沟液中IL-1β浓度比较无统计学差异,治疗后实验组龈沟液中IL-1β浓度明显低于对照组,差异有统计学意义(p0.05)。结论:LLLT对固定正畸患者牙龈炎有一定的防治作用。
[Abstract]:Objective: with the improvement of people's living conditions, people's pursuit of beauty is becoming higher and higher. Therefore, more and more people pay attention to malocclusion, and more patients choose to receive fixed orthodontic treatment. Gingivitis is one of the common complications in the process of fixation and correction. Some studies have shown that low intensity laser 1ow level laser LLL) has the biological regulation effect, can reduce the inflammation reaction of the tissue and promote wound healing. The purpose of this study was to investigate the efficacy of low intensity laser in the treatment of orthodontic gingivitis, to provide reference for the treatment of orthodontic gingivitis and to provide theoretical basis for the clinical application of LLL in orthodontic treatment. Methods: twenty patients with fixed orthodontic gingivitis aged 12 to 18 years (12 males and 8 females) with an average age of 15.2 years were selected. Every patient was given routine oral hygiene education and periodontal cleaning before the experiment. After a week of basic periodontal treatment, each patient was randomly divided into experimental group and control group. The plaque index (pli), gingival index (Gingival index), bleeding index (Blooding index) and probing depth probing (PDD) were measured. The concentration of IL-1 尾 in gingival crevicular fluid was determined as "before treatment". The gingiva of the experimental group was treated with low intensity laser therapy once a day, and the control group was not treated. One week later, four periodontal clinical indexes and the concentration of IL-1 尾 in gingival crevicular fluid were measured again in the experimental group and the control group. All examinations are performed by the same physician. The indexes before and after treatment were compared and statistically analyzed. The result is 1: 1. Comparison of periodontal clinical indexes: there was no significant difference between the experimental group and the control group before and after treatment. After treatment, the four indexes in the experimental group were significantly lower than those in the control group, and the difference was statistically significant (P 0.05 路2). Comparison of IL-1 尾 concentration in gingival crevicular fluid: there was no significant difference in IL-1 尾 concentration between experimental group and control group before treatment. After treatment, IL-1 尾 concentration in gingival crevicular fluid in experimental group was significantly lower than that in control group (P 0.05). Conclusion: WL LLLT can prevent and cure gingivitis in fixed orthodontic patients.
