    • 摘要: 目的评定重组牛碱性成纤维细胞生长因子(rbFGF)使用在脱位牙再植术患者中的再植意义。方法对2018年2月至2020年3月本院急诊综合科治疗的62例脱位牙患者实施指标项目计算,用随机数字表方法分为两组,各31例。观察组采取重组牛碱性成纤维细胞生长因子干预后再植术,对照组采取传统复位固定再植术,比较研究再植成功率和满意率。结果观察组再植成功率和满意率高于对照组,组间比较差异有统计学意义(P<0.05)。结论在脱位牙再植术患者中采用重组牛碱性成纤维细胞生长因子再植效果较好。

    • 摘要: 目的:通过体外细胞培养模拟牙脱位保存模型,研究不同保存介质和保存温度对人牙周膜细胞活性和增殖能力的影响.方法:选择3种易于获得的保存介质牛奶、唾液和纯净水,分别在室温和4°C条件下作用于人牙周膜成纤维细胞(hPDLFs)1 h,然后利用5-乙炔基-2'脱氧尿嘧啶核苷(EdU)和细胞增殖检测试剂盒(CCK-8)实验检测作用后hPDLFs细胞的活性和后期增殖能力.结果:EdU实验结果显示,在4°C保存温度下,牛奶处理hPDLFs细胞1h后,EdU阳性细胞(绿色)最多,约占总细胞的50.9%.CCK-8实验结果显示,4°C下牛奶、唾液、纯净水中hPDLFs活力依次约为62.8%、17.8%和3.3%,室温下则依次为56.2%、15.2%和0.7%.培养24、48、72 h后,细胞保存于4 °C牛奶中生长曲线最接近于正常对照,与保存于唾液和纯净水中的细胞相比,细胞增殖速率差异具有统计学意义.结论:hPDLFs在4°C牛奶中表现出了最佳的细胞活力和增殖能力,因此低温牛奶是外伤脱位牙首选的保存液.

    • 摘要: Objective:To evaluate the effect of four common in vitro dislocated teeth storage medium on the biological activity of periodontal ligament fibroblasts.Method:A total of 200 mandibular first premolars extracted from 200 cases of 14-22 year old adolescents in our hospital due to orthodontic treatment from January 2017 to January 2018 were selected as the research objects.They were randomly divided into four experimental groups (saline group, milk group, saliva group, tap water group) and control group, 40 teeth in each group.The periodontal ligament fibroblasts were cultured in the dislocation teeth.The experimental group were treated with saline, milk, saliva and tap water as storage medium respectively, while the control group was stored directly in air.The periodontal ligament cells were detected by CCK-8 method in the storage medium of four common in vitro dislocation teeth for 2, 6, 12 and 24 h respectively.The activity at different time points were compared with the control group.Result:The survival rate of periodontal ligament cells in each experimental group at different time points were significantly higher than those in the control group, the differences were statistically significant (P<0.05).The survival rate of periodontal ligament cells in the saline, milk and saliva groups at different time points were significantly higher than those in the tap water group, the differences were statistically significant (P<0.05).The survival rate of periodontal ligament cells in the milk and saliva groups at different time points were significantly higher than those in the saline group, and the survival rate of periodontal ligament cells in the milk group at 12 and 24 h was significantly higher than that in the saliva group, the differences were statistically significant (P<0.05).Conclusion:The periodontal ligament fibroblasts stored in milk and saliva have higher activity and can be used as effective temporary storage solution for dislocated teeth in vitro.The storage effect of saline is the second, while that of tap water is the worst, and it is not suitable for storage medium.%目的:评价比较四种常见离体脱位牙贮存介质对牙周膜成纤维细胞活性的影响.方法:选取2017年1月-2018年1月本院口腔临床14~22岁青少年200例因正畸需要拔除的下颌第一前磨牙200颗作为研究对象, 将其随机分为四组试验组 (生理盐水组、牛奶组、唾液组、自来水组) 和对照组, 各40颗.培养脱位牙中的牙周膜成纤维细胞, 其中试验分别采用生理盐水、牛奶、唾液、自来水作为贮存介质, 对照组则直接在空气中保存.采用CCK-8法分别检测牙周膜细胞在四种常见离体脱位牙贮存介质中2、6、12、24 h不同时间点的活性, 并与对照组进行比较.结果:各试验组不同时间点的牙周膜细胞存活率均明显高于对照组, 差异均有统计学意义 (P<0.05) .生理盐水、牛奶及唾液组不同时间点的牙周膜细胞存活率均明显高于自来水组, 差异均有统计学意义 (P<0.05) .牛奶、唾液组不同时间点的牙周膜细胞存活率均明显高于生理盐水, 且牛奶组12、24 h的牙周膜细胞存活率均明显高于唾液组, 差异均有统计学意义 (P<0.05) .结论:牛奶、唾液贮存的牙周膜成纤维细胞活性较高, 可作为有效的离体脱位牙临时贮存液, 而生理盐水的保存效果次之, 而自来水保存效果最差, 不适合作为贮存介质.

    • 摘要: Objective:To introduce a new material for the fixation of subluxated teeth and alveolar fractures. Methods:106 patients totally with 264 subluxated teeth during the five years of clinical treatment were assigned, and 13 patients were accompanied with alveolar fracture. The luxated teeth included 172 maxillary incisors, 84 mandibular incisors, and 9 premolars. The subluxation teeth were forced back into normal alignment and ligated with 0.2 mm nylon thread to the ad-joining teeth in a figure-of-eight fashion. More stability was gained by banding two teeth. Patients were followed up for 1-36 months. The definition of failure was periodontium swelling and overflow pus, or the X-ray showing alveolar bone and root absorption. Results: After the nylon thread appliance was removed, 246 teeth (93.2%) had become firm attached in position, and 18 diseased teeth failed to treatment. Conclusion: Nylon thread as a fixation material, is effective in the menagement of luxation of teeth.%目的:介绍1种新的外伤牙松动、脱位及牙槽突骨折复位固定方法.方法:通过正确的复位,应用0.2 mm尼龙线,将松动或脱位牙两边1~2个正常牙上与需固定的牙连续结扎在一起,反复结扎3道进行固定.结果:经尼龙线在外伤松动牙、脱位牙及牙槽突骨折复位固定方面5年的临床应用,共治疗患者106例,患牙265颗,上前牙172颗、下前牙84颗、前磨牙9颗,伴牙槽突骨折13例.牙周有红肿及溢脓、患牙疼痛不适、患牙松动度大于Ⅰ度以上、X片显示牙槽骨及牙根有吸收,均评价为失败病例.固定后通过1~36个月的随访,共失败10例18颗牙,成功率93.2%.结论:尼龙线固定外伤松动牙、脱位牙及伴有牙槽突骨折移位牙时,是一种行之有效的方法,在固位的稳定性、美观、舒适性方面均取得较好临床效果.

    • 摘要: Objective To provide fundamental data for understanding the difference between various treatment fluids and to investi-gate the best treatment fluid for teeth replantation. Methods 277 premolars extracted for orthodontics will be collected to simulate the avulsed teeth and then soaked in HBSS,milk and 2% NaF at different drying time. Trypan blue staining technique will be used to detect the viability of PDL cells,and then subjected to statistical analysis using analysis of variance. And the morphologic changes of PDL will be observed under the microscope. Results The viability of PDL cells soaked in HBSS showed higher viability(94. 60 ± 0. 72)% than that in 2%NaF(84. 37 ± 3. 98)% at 30 mins; At 60 mins and 120 mins,the viability of PDL cells soaked in HBSS (63. 03 ± 3. 05)%,(13. 38 ± 1. 04)% was higher than that in milk (48. 9 ± 3. 47)%,(5. 73 ± 1. 29)% and 2% NaF (51. 93 ± 1. 72)%, (8. 60 ± 0. 74)% respectively. Conclusions All the three solutions have repairing effect on viability of the PDL cells,and HBSS is the best one.%目的:观察比较Hanks′平衡盐溶液(简称HBSS)、牛奶及2%NaF这几种不同处理液对干燥放置的脱位牙牙周膜作用效果的差异,为临床选择适宜的处理液提供实验依据。方法收集因正畸治疗需要而拔除的前磨牙277颗模拟外伤脱位牙,在不同干燥放置时间点分别用HBSS、牛奶及2%NaF进行浸泡处理后,采用台盼蓝染色计数法及HE染色技术,观察比较各种条件下根面牙周膜细胞的存活状况及组织学表现。结果干燥时间为0.5 h时,HBSS组牙周膜细胞存活率(94.60±0.72)%,大于2%NaF组(84.37±3.98)%,差异有显著性(P <0.05);干燥时间为2、4 h 时,HBSS 组牙周膜细胞存活率(63.03±3.05)%、(13.38±1.04)%大于牛奶组(48.9±3.47)%、(5.73±1.29)%及2%NaF组(51.93±1.72)%、(8.60±0.74)%,有统计学意义(P<0.05)。结论不同处理液对于离体干燥保存的脱位牙的牙周膜的修复作用各有不同,HBSS的效果相对较好。
