    • 摘要: 探究以聚乳酸-羟基乙酸共聚物(PLGA)凝胶为载体的成骨诱导剂(OI)缓释系统对拔牙创骨改建的影响.选取健康新西兰大白兔27只,随机分为PLGA+OI、PLGA和空白组各9只,拔除双侧下前牙后,各组拔牙窝内分别注入OI缓释系统,空载PLGA凝胶和不做处理.拔牙后2、4、8周每组各处死3只动物,取下颌牙槽骨标本行影像学检查和组织学检查.2、4、8周PLGA+OI组新生骨密度大于PLGA组与空白组,差异具有统计学意义(P<0.001);8周时PLGA+OI组牙槽骨宽度(ABW)与牙槽骨高度(ABH)吸收值均小于PLGA组和空白组(P<0.001);PLGA+OI组术后新生骨形成早于PLGA组和空白组.OI缓释系统能促进拔牙创骨改建,减少ABW和ABH的吸收,具有较好的应用前景.

    • 摘要: 拔除36只兔的双侧下颌第一磨牙,拔牙创处理分为4组(n=9),A组:PRF联合ADM组;B组:PRF组;C组:ADM组;D组:对照组.不同时间点牙槽骨高度与宽度比较各组间差异无显著性(P>0.05);骨计量学各参数比较:术后2、4周各组之间比较有统计学意义(P<0.01),A组最优;术后8周B组与C组差异无显著性(P>0.05),A组分别与另2组比较有统计学意义(P<0.01),A组最优.PRF联合ADM促进拔牙窝愈合效果最佳.%Bilateral mandibular first molars of 36 rabbits were extracted.The tooth extraction wounds were treated by:platelet-rich fibrin +acellular dermal matrix(group A),platelet-rich fibrin(group B),acellular dermal matrix (group C) and without treatment (group D,the control) (n =9) respectively.The measurments of alveolar bone height and width showed that there were no significant differences among groups at different times(P > 0.05).Bone histomorphometry showed that at the 2th and 4th week,the best result was found in group A(P<0.01).While,at the 8th week,the result of group A was still better than that of other 3 ones (P < 0.01),but group B and C showed no significant difference(P > 0.05).The combination of PRF and ADM shows the most significant effect.

    • 摘要: Objective To establish an experimental animal model of tooth extraction wounds in ovariectomized osteoporotic rats.Methods Twenty-four female SD rats aged 3 months old were randomly divided into two study groups as follows:the model group and the control group.2 months after ovariectomy,both groups accepted left maxillary first molar extraction.The rats were sacrificed 2 months after ovariectomy and 2,4,8 weeks after tooth extraction respectively.Body weight,serum levels of biochemical indices,Micro-computed tomography (Micro-CT) and histological examination were assessed.Results Before ovariectomy,there was no significant difference between the model group((300.52±5.94) g) and the control group((298.88±6.21) g) in body weight.Compared with the control group((328.30± 10.03)g),the body weight increased significantly (P<0.05) in the model group((355.64± 12.09)g) 2 months after ovariectomy.Estradiol was significantly lower (P< 0.05) in the model group ((10.21 ± 4.35) pg/mL) compared with the control group((22.49±2.94) pg/mL) and the femurs trabecular was thinner in the model group 2 months after ovariectomy.The Micro-CT scanning demonstrated that the trabecular thickness in the model group (4-week (0.113 8 ± 0.009 9) mm,8-week (0.122 7 ±0.019 7)mm) was significantly lower than in the control group(4-week (0.142 3±0.010 6)mm,8-week (0.201 3±0.052 7)mm) 4,8 weeks after tooth extraction.Histology showed less and thinner trabeculae arranged in disorder,less bone mass and lower quality of new bone healing in the model group compared with the control group.Conclusions Experimental tooth extraction socket model in ovariectomized osteoporotic rats can be established by ovariectomy plus left maxillary first molar extraction.This model offers a good method to study the relationship between the healing of tooth extraction wounds and postmenopausal osteoporosis.%目的 通过卵巢切除术及大鼠左侧上颌第一磨牙拔除术建立去卵巢骨质疏松大鼠拔牙创模型.方法 选用3个月龄雌性SD大鼠24只,随机分为模型组、对照组,每组12只,卵巢切除术2个月后对两组大鼠行左侧上颌第一磨牙拔除术,于卵巢切除术后2个月及拔牙术后第2、4、8周分4批处死大鼠,通过体质量、血清生化检测、Micro-CT检测及组织学观察对动物模型进行评价.结果 卵巢切除术前模型组体质量((300.52±5.94)g)与对照组((298.88±6.21)g)相比无显著差异;术后2个月,模型组((355.64±12.09)g)相比于对照组((328.30±10.03)g)体质量明显增加(P<0.05).卵巢切除术后2个月模型组雌二醇水平((10.21±4.35) pg/mL)较对照组((22.49±2.94) pg/mL)明显降低(P<0.05),同时模型组大鼠股骨远端骨小梁较为稀疏不连续.Micro-CT示拔牙术后(4周(0.113 8±0.009 9)mm,8周(0.122 7±0.019 7)mm)模型组骨小梁厚度均明显低于对照组(4周(0.142 3±0.010 6)mm,8周(0.201 3±0.052 7)mm) (P<0.05).组织学观察显示拔牙术后模型组拔牙创骨小梁纤细,稀疏,不规则,骨量少,新骨愈合质量降低.结论 采用卵巢切除术结合大鼠左侧上颌第一磨牙拔除术可建立去卵巢骨质疏松大鼠拔牙创模型,为探讨绝经后骨质疏松对拔牙创愈合的影响及其机制提供了有效的手段.

    • 摘要: 目的 探讨骨皮质钉在犬拔牙位点保存中的应用.方法 以四只成年雄性杂种犬建立动物实验模型,以每只犬双侧下颌第二、三小臼齿远中根的拔牙窝为实验位点,分别即刻植入Bio-Oss骨粉、明胶海绵、骨皮质钉或自然愈合.术后三个月取标本,进行标本固定.采用标本大体观察;骨性标本测量牙槽骨高度改变值及CT断层片测量牙槽骨宽度值行统计学分析对比.结果 骨皮质钉组标本软组织外观丰满、保留了较宽的角化组织带、软组织顶端外形平坦;经骨皮质钉植入的犬拔牙后位点保存均优于其他组(P<0.05),经Bio-Oss植入组均优于明胶海绵植入组和自然愈合组(P<0.05);余两组无明显统计学差异(P>0.05).结论 骨皮质钉植入对犬拔牙后位点保存有显著作用.

    • 摘要: Objective To observe the difference between the self-repair of gingival tissue in retained dental root and the soft tissue healing after tooth extraction in the area of the anterior teeth of the canines. Methods Residual roots models were made in the three dogs' maxillary anterior teeth areas ( right maxillary lateral incisor and left max-illary central incisor) . Moreover, the three dogs' left mandibular lateral incisors were extracted. Then, the degrees of growth under the two different gingiva healing conditions were observed in the 1st, 3rd, 4th and 5th week after surgery. Besides, the gingival hyperplasia tissue in the left maxillary central incisor and soft tissue hyperplasia in the left mandibular lateral incisor tooth were obtained at 3rd, 4th and 5th week after surgery respectively for histo-logical observation. Results We found that the new soft tissue around residual root was overgrown on cross-section in the 4th week after surgery by the unaided eye, and the texture and color of the new soft tissue in the 5th week af-ter surgery was similar to that of the normal gingiva. Meanwhile, soft tissue which was harder in texture and lighter in color compared with the normal gingiva was fully covered on wound 3 weeks after tooth extractions. Histological observation found that the new born soft tissue hyperplasia around the residual roots mainly was squamous cell hy-perplasia, and the inflammatory cells infiltration was not obvious. On the contrary, histological observation on the soft tissue around the tooth extraction wound demonstrated obvious inflammatory cells infiltration and mild squamous cell hyperplasia. Conclusion The hyperplasia and healing of gingival tissue in reserving residual roots are slower than those in soft tissue after extracting a tooth, but it is more similar to the normal gingiva.%目的:观察残根保留情况下牙龈软组织的自我修复与拔牙后软组织愈合在犬前牙区软组织愈合中的不同。方法在A、B、C3只犬的上颌前牙区(右上颌侧切牙,左上颌中切牙)制造残根模型,将牙冠磨至龈缘下,勿损伤牙龈(将此设为残根组);拔除3只犬的左下颌侧切牙(将此设为拔牙组);术后第1、3、4、5周观察两种不同牙龈愈合生长的情况,并在术后第3、4、5周按照A、B、C顺序取左上颌中切牙牙龈增生组织、左下颌侧切牙拔牙创增生软组织进行组织学观察。结果术后第4周时肉眼观察到残根周围新生软组织基本长满断面,第5周时新生软组织的质地及颜色与正常牙龈基本一致;拔牙术后第3周时软组织已基本长满创面,但肉眼观察其颜色较浅,质地较硬;组织学观察残根周围新增生的软组织以增生的鳞状上皮为主,炎细胞浸润不明显;而拔牙创周围软组织则表现为明显的炎细胞浸润,鳞状上皮轻度增生。结论采用保留残根后新增生的牙龈软组织较拔牙后软组织愈合慢,但是更接近于正常牙龈组织。
