| 1 | 渗透树脂对正畸后牙齿白垩斑的疗效及牙面微硬度和颜色稳定性的影响显示文摘目的:探讨渗透树脂对正畸后牙齿白垩斑及牙面微硬度、颜色稳定性的影响。方法:选择2016年1月至2016年12月笔者医院就诊的牙齿正畸患者64例,每人取1颗因正畸治疗需拔掉的牙齿为研究对象,共64颗。按随机数表法分为观察组和对照组,每组32颗。将所有牙齿人工制造脱矿病损面模拟正畸后牙齿发生白垩斑,给予观察组ICON渗透树脂治疗,对照组采用多乐氟进行治疗。治疗1个月后,比较两组牙齿治疗前后的病损面积比、治疗有效率、患牙表面显微硬度(surface microhardness,SMH)、L*值及患牙白垩斑评分。结果:经治疗,观察组病损面积比低于对照组,有效率明显高于对照组[(5.79±9.62)%vs(14.65±10.28)%,(85.77±18.76)%vs(58.56±21.48)%](P<0.05);观察组患牙表面显微硬度及L*值均明显高于对照组[(198.44±31.42)vs(130.28±22.47),(82.04±3.37)vs(78.79±4.06)](P<0.05);观察组计算机软件评分及专业医师评分均高于对照组[(44.89±1.42)分vs(39.57±1.76)分,(45.36±1.78)分vs(40.04±2.06)分](P<0.05)。结论:正畸后牙齿白垩斑采用ICON渗透树脂治疗,可有效减少病损面积,提高牙釉质表面的显微硬度,同时还可改善正畸后白垩斑病损的美观效果。 | 邹毅军 罗琴 张靖江 杨智勇 | 2018 | 中国美容医学2018，27，3： | 6 |
| 2 | 渗透树脂对正畸后牙齿白垩斑的疗效及牙面粗糙程度和颜色的影响分析显示文摘目的:探讨渗透树脂对正畸后牙齿白垩斑的疗效,以及对牙齿表面的粗糙程度和牙齿颜色的影响因素。方法:收集笔者医院口腔科就诊的牙齿正畸后出现白垩斑的80例患者,每位患者选取1颗因正畸治疗而需要拔掉的牙齿作为研究对象,共计80颗患牙。将80颗患牙随机分为实验组和对照组,每组40颗。将所有患牙行人工脱矿制造病损面,以模拟正畸后牙齿所发生的白垩斑。实验组采取ICON渗透树脂治疗,对照组采用多乐氟治疗。所有患者治疗1个月后,分别比较两组患者牙齿治疗前后的病损面积、有效率、牙面粗糙程度,国际照明委员会(Commission Internationaled’Eclairage, CIE) L*a*b*值以及牙齿的白垩斑评分。结果:经过1个月治疗,实验组患牙的病损面积比治疗前明显缩小(P<0.05),而且实验组的病损面积明显低于对照组,差异有统计学意义(P<0.05);实验组患牙的治疗有效率为85.8%,明显高于对照组的58.6%,差异有统计学意义(P<0.05);实验组患牙的牙面粗糙程度(1.8±0.5)μm,而对照组患牙(2.0±0.5)μm,两组间差异显著,具有统计学意义(P<0.05);实验组患牙的L*a*b*值明显高于对照组,分别为82.0±3.4、78.8±4.1,组间比较有显著性差异,具有统计学意义(P<0.05);实验组患牙的白垩斑计算机评分与专业医师评分分别为44.9±1.4、45.3±1.8,而对照组患牙的评分为39.4±4.1、40.0±2.2,具有统计学意义(P<0.05)。结论:渗透树脂对于正畸后牙齿白垩斑的治疗有效,可以减少病损面积,同时渗透树脂治疗白垩斑后牙面粗糙程度疗效较高,可有效改善白垩斑病损的美观程度。 | 刘梦蕾 刘静雅 韩晶 桂艳丽 甘郑宁 | 2019 | 中国美容医学2019，28，6： | 5 |
| 3 | 渗透树脂于早期龋中的应用新进展显示文摘渗透树脂可以有效阻止早期龋的进展,同时其微创的优点给临床工作带来更多可能性,目前渗透树脂应用于早期龋及正畸治疗后出现的白色斑点病损可取得较好效果,但其适应证需要严格把握,材料的发展也与其应用范围息息相关。近年来有不少关于渗透树脂性能及应用进一步发展的国内外研究,本文就上述研究进展进行综述。 | 吴景溢 赵月萍 | 2019 | 广东化工2019，46，23： | 1 |
| 4 | Ionic liquid-loaded microcapsules doped into dental resin infiltrants显示文摘Resin infiltrants have been effectively applied in dentistry to manage non-cavitated carious lesions in proximal dental surfaces.However,the common formulations are composed of inert methacrylate monomers.In this study,we developed a novel resin infiltrant with microcapsules loaded with an ionic liquid(MC-IL),and analyzed the physical properties and cytotoxicity of the dental resin.First,the ionic liquid 1-n-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide(BMI.NTf2)was synthesized.BMI.NTf2 has previously shown antibacterial activity in a dental resin.Then,MC-IL were synthesized by the deposition of a preformed polymer.The MC-IL were analyzed for particle size and de-agglomeration effect via laser diffraction analysis and shape via scanning electron microscopy(SEM).The infiltrants were formulated,and the MC-IL were incorporated at 2.5%,5%,and 10 wt%.A group without MC-IL was used as a control.The infiltrants were evaluated for ultimate tensile strength(UTS),contact angle,surface free energy(SFE),and cytotoxicity.The MC-IL showed a mean particle size of 1.64(±0.08)μm,shriveled aspect,and a de-agglomeration profile suggestive of nanoparticles’presence in the synthesized powder.There were no differences in UTS among groups(p>0.05).The incorporation of 10 wt%of MC-IL increased the contact angle(p<0.05),while the addition from 5 wt%reduced the SFE in comparison to the control group(p<0.05).The human cell viability was above 90%for all groups(p>0.05).The incorporation of microcapsules as a drug-delivery system for ionic liquids may be a promising strategy to improve dental restorative materials. | Marla Cuppini Isadora Martini Garcia Virgínia Serra de Souza Kelly Cristine Zatta Fernanda Visioli Vicente Castelo Branco Leitune Sílvia Stanisçuazki Guterres Jackson Damiani Scholten Fabrício Mezzomo Collares | 2021 | Bioactive Materials2021，6，9： | 0 |
