目的 观察Listerine(R) 漱口水对固定矫治患者牙周及牙菌斑的影响.方法 选择30例固定矫治患者,年龄12～25岁,随机分成实验组和对照组,实验组使用Listerine(R) 漱口水漱口,对照组不使用漱口水.分别测量治疗初,3个月,6个月时的菌斑指数(PLI),牙龈指数(GI),出血指数(BI).应用SPSS10.0统计软件,采用Student-newman-Keuls比较不同时间各指数间的差异.采用t检验比较同一时间同一指数实验组和对照组间的差异.以P≤0.05为有统计学意义.结果 实验组在3个月,6个月时BI,PLI,GI升高缓慢,无统计学意义.实验组在3个月和6个月时的PLI,GI,BI值明显低于对照组,且有统计学差异,PLI:(P<0.01),GI:(P<0.01),BI:(P<0.001).6个月时对照组同实验组间的PLI,GI,BI也有明显的统计学差异(P<0.001).结论 使用Listerine(R) 漱口水可以明显减少固定矫治患者的牙菌斑及牙龈炎的发生发展,有利于患者保持口腔卫生.     

Listerine~漱口水抑制牙菌斑再生效果的临床研究

目的:观察Listerine~漱口水体内抗菌斑的效果。方法:按纳入标准在武汉大学学生志愿者中随机抽取20人(20～25岁)。实验期间,依据双盲、自身对照的原则,每一个受试者分别随机先后含漱Listerine~漱口水(试验组)、安慰剂(阴性对照组)、0.12%氯已定含漱液(阳性对照组)。每种漱口水使用4d,期间停止一切口腔清洁措施。4d后,采用改良Qiugley-Hein菌斑指数记录法,记录PLI值。中间间隔10d,再使用另一种漱口水。应用SPSS14.0统计软件,采用单因素方差分析各组PLI值,非参数检验分析各组漱口水副反应差异。结果:在抑制牙菌斑形成方面Listerine~漱口水与安慰剂相比较,有显著性统计学差异(P<0.001),但不及氯已定漱口水(P<0.05)。氯已定含漱液易引起味觉的改变,口味满意程度也差于Listerine~漱口水(P<0.05)。结论:Listerine~漱口水在抑制牙菌斑形成方面有一定的效果,且副反应小。

A practice-based randomised controlled trial of the efficacy of an electric and a manual toothbrush on gingival health in patients with fixed orthodontic appliances

Objectives. The aim of the present study was to evaluate the efficacy of an electric toothbrush with a specially designed orthodontic brush head compared with a manual toothbrush in controlling plaque and gingivitis in patients with fixed orthodontic appliances over an 8-week period in a dental practice setting.

Methods. This was a randomised controlled, single blind, stratified, parallel group trial conducted in two specialist orthodontic dental practices by a specialist orthodontist. Group 1 comprised 41 subjects who used the electric toothbrush and Group 2 consisted of 43 subjects who brushed with a manual toothbrush around the orthodontic appliance for a timed 2 minutes twice daily for 8 weeks.

Plaque around the fixed appliance attachments was measured using an orthodontic modification to the Silness and Loe plaque index, while gingival condition was scored using the gingival index and Eastman interdental bleeding index.

Results. There was baseline balance for all clinical variables (p>0.05). Both groups had significantly less plaque after 8 weeks than at baseline (p<0.001) but the group using the electric brush also had significantly less interdental gingival bleeding, as determined by the Eastman interdental bleeding index both at week 4 (p<0.001) and week 8 (p=0.004). The majority of subjects (n=54, 64.3%) preferred the electric toothbrush.

Conclusions. In conclusion, the results from this study would suggest that use of an electric toothbrush with an orthodontic brush head may be of benefit in promoting gingival health in fixed orthodontic appliance patients; however, the long-term effects (over at least 6 months) need to be evaluated.     

Quantifying plaque during orthodontic treatment:: A systematic review

Objective:To evaluate the literature on different methods of scoring plaque in patients with fixed orthodontic appliances.Materials and Methods:A systematic electronic and hand search using MEDLINE and PubMed was conducted.Results:Most orthodontic trials have used the original Silness and Löe plaque index. Indices vary in several potentially important aspects. Only two papers have reported reproducibility of methods of plaque scoring in orthodontic patients.Conclusion:Some plaque indices are inappropriate for orthodontic patients. Newer digital planimetric methods are promising if more complex. There is a need to further assess the reproducibility and practicability of the advocated methods.     

固定矫治器粘结前后牙齿颊面菌斑pH值和变形链球菌附着的改变

目的对固定矫治器粘结前后牙颊面菌斑pH值和变形链球菌附着量、比例进行研究,初步探讨固定矫治中菌斑微生态的变化。方法应用离子选择性微电极测定菌斑提取液的pH值,对变形链球菌和总厌氧菌进行培养,记数。结果固定矫治器粘结后牙面菌斑pH值有极显著的下降(p<0.001),粘结一周后下降了0.5,三周后下降了0.7。菌斑湿重在粘结后三周有显著增多(p<0.05)。变形链球菌附着量、比例有极显著的升高(p<0.001)。粘结后一周,变形链球菌的数目平均上升了8.85×1011CFU/g;粘结后三周,平均上升了4.20×1011CFU/g,比例增加了1.10％。结论固定矫治器粘结后颊面菌斑的致龋性增强,但并未转化为致龋性菌斑。固定正畸与龋易感性的关系有待进一步研究。     

固定矫治患者菌斑指数、牙龈指数、龈沟出血指数的临床分析

目的:观察正畸患者在固定矫治治疗中的菌斑指数(PLI)、牙龈指数(GI)和龈沟出血指数(SBI)的分布及变化。方法:实验组为331例采用固定矫治器治疗半年以上的正畸患者,其中男101例,女230例,年龄12～15岁,均居住城市,无开口呼吸的不良习惯。另以12～15岁初中生375例作为对照组,其中男196例,女179例,无正畸治疗史;检查4个上切牙和4个下切牙的PLI、GI和SBI值,采用SPSS10.0统计软件包对相关组间数据进行t检验。结果:正畸患者的PLI、GI和SBI值均显著高于对照组(P<0.01),对照组中男性的PLI值显著高于女性(P<0.01);在正畸患者中,PLI值无性别间差异(P>0.05),但男性的GI和SBI值显著高于女性(P<0.01),男性下切牙的PLI、GI值显著高于上切牙(P<0.01),女性上、下切牙的PLI、GI和SBI值均无差异(P>0.05),说明戴固定矫治器使口腔卫生难以实施,在矫治期间男性的口腔卫生情况较女性差,而下切牙的卫生情况较上切牙差。结论:为维护牙周健康,对接受固定矫治的患者进行口腔卫生宣教十分重要,特别需注意对下切牙菌斑的控制。     

Efficacy of Listerine antiseptic in inhibiting the development of plaque and gingivitis

A 9-month double-blind controlled clinical study was conducted on adult subjects using either Listerine antiseptic, its vehicle control, or a water control in order to determine the efficacy of the antiseptic mouthrinse in inhibiting the development of plaque and gingivitis. Following screening examinations for minimal entry levels of plaque and gingivitis, all subjects received a complete prophylaxis. Subjects then continued their usual oral hygiene habits for a 3-week normalization period and were examined for soft tissue abnormalities and baseline measurements of plaque, gingivitis, and tooth stain. 2 additional prophylaxes were then performed, followed by a second baseline gingival examination. Zero plaque was re-established by rubber cup polishing and twice daily rinsing was begun. Soft tissue, plaque, gingivitis, and extrinsic tooth stain were evaluated after 1, 3, 6 and 9 months of rinsing with the randomly assigned mouthrinses. Results demonstrated that Listerine antiseptic significantly reduced the development of plaque at 1, 3, 6 and 9 months and the development of gingivitis at 9 months, as compared to its vehicle control or water control.     

Effects of orthodontic treatment with aligners and fixed appliances on speech:: A randomized clinical trial

ObjectivesTo evaluate effects of orthodontic treatment with aligners and conventional fixed appliances on production of speech.Materials and MethodsThis was a parallel, randomized clinical trial. Patients with Angle Class I malocclusion, moderate crowding, and no speech impairment were randomly allocated to two groups: patients with orthodontic aligners (OAs; n = 20; mean age = 23.60 ± 5.65 years) and those with conventional fixed appliances (n = 20; mean age = 20.56 ± 4.51 years) and treated at the University of North Parana''s clinic in Londrina, Brazil. Evaluation of speech production was performed semiobjectively by a speech therapist (myofunctional orofacial examination) and subjectively (self-assessment) at five time points: baseline, immediately after insertion of appliances, and subsequently at 3, 30, and 180 days after insertion. For intergroup comparison, independent t, χ², Fisher exact, and Mann-Whitney tests were used; for intragroup comparison, the Friedman test was applied (α = 5%).ResultsIn the semiobjective evaluation, patients with OAs exhibited a change in production of speech production, compared with patients with fixed appliances, immediately and 3 days after insertion of appliances (P < .001). Thirty days after insertion, the groups were similar (P = .487), an outcome that was unchanged at 180 days. However, in the self-assessments, patients in both groups reported significant speech difficulties immediately and 3 days after insertion of appliances, but such impairment was no longer perceived at 30 days or 180 days.ConclusionsAlthough the speech therapist identified changes in speech production at the start of treatment in the OA group only, patient self-assessments demonstrated that orthodontic treatment, regardless of the type of appliance used, interfered with their perception of speech.
