This in vivo study was to examine the historical changes of implanted novel chitosan/collagen composite barrier for confirming the clinical feasibility. Four other commercial GTR membranes were chosen for comparison. Among the resorbable GTR membranes, BioMend Extend and Peri-Aid are collagen base, and GORE-TEX OSSEOQUEST is synthesized membrane, while GORE-TEX e-PTFE (Expanded polytetrafluoroethylene) is synthesized but non-resorbable. Beagle dogs were used as animal model. Buccal mucoperiosteal flaps were reflected in the bilateral mandibular premolar and molar areas. Buccal alveolar bone was reduced on 1st、2nd premolar and molar to a level 5 mm apical to the cemento-enemel junction. Root surface was denuded of periodontal ligament and cementum, and notches were placed at the bone level of each root. The tested GTR barriers were implanted in critical bone defect areas. Flaps were coronally positioned and sutured. Two beagle dogs were sacrificed each time as the designed time period after surgery. Histological and histometirc evaluation at 7 days、14 days、28 days、3 months were performed post-operatively to determine the healing response of each treatment modality.

本研究之目的在评估与工研院生医中心合作发展出可吸收性去乙醯几丁聚醣/胶原蛋白复合之组织导引再生膜片，并选择与可吸收性之BioMend Extend 及Peri-Aid 胶原蛋白膜片，和GORE-TEX OSSEOQUEST 合成高分子膜片，及不可吸收之GORE-TEX e-PTFE合成高分子膜片，等其他四种市售商品材料共同对照评估，应用8只年龄为12个月的雄性小猎犬，均分4组(分别为7天、14天、28天、3个月)，为动物活体评估模式，在实验犬之左、右下颚第一、二小臼齿及大臼齿的颊侧区制造骨缺损后，分别植入组织导引再生膜片，依实验设定时间将小猎犬牺牲，取下缺损区骨头，以光学显微镜观察量测其牙垩质再生高度与齿槽骨再生高度之变化，以探讨其组织再生模式及评估新膜片在临床应用之适用性。

But in the cold morning hour, crouching in the corner of the wall, the poor

直到寒冷的早晨，人们发现一个可怜的小姑娘蜷缩在墙角里，她双颊通红，嘴唇上带着

M. Paer, the author of Agnese, a good sort of fellow, with a square face and a wart on his cheek, directed the little private concerts of the Marquise de Sasenaye in the Rue Ville l'Eveque

As Francisca and I said our farewells at the airport, I caressed her cheek.

法兰西丝卡在机场和我道别的时候，我摸摸她的双颊。

This indicated that geniohyoid paralleling with the direction of distraction presents adaptive changes such as muscular hypertrophy and muscle fiber type transformation.

这说明与牵张方向平行的颊舌骨肌在牵张过程中出现了肌肉增生与肌纤维类型转变等适应性变化，而与牵张方向垂直的嚼肌受其影响不大。

The colour mantled in her delicate sunburnt cheeks.

她那被太阳晒黑了的娇嫩的双颊泛起了红晕。

A great predominance of two very close canals in the mesiobuccal root of maxillary molars has been demo...

根管治疗目前的成功率虽然已很高，但是在上腭第一恒磨牙有近中颊侧第二根管案例，假使无法找到或者充填好，那么失败的可能性就增加了。

MB1 root canals of the mesiobuccal root canals in maxillary molars were found obvious curve out by the rate of 82.5% in mesiodistal direction,77.5% in buccoling

上颌第一恒磨牙四个根管在近远中方向、颊舌方向均有不同程度的弯曲，其第二弯曲出现的情况也各不相同。

本研究通过对80例离体上颌第一磨牙行近远中方向，颊舌方向x 线投照，旨在近一步了结其根管的弯曲走向，弯曲程度，弯曲位置。X线片只能反应根管在一个平面上的走向、形态。

Physical examination disclosed anontender mass in the right maxillary mucobuccal fold and the magnetic resonance imaging revealed asolid mass occupied in the right maxillary sinus.Enucleation combined with peripheral ostectomy was performed.

就诊的两个月前患者口腔及鼻腔内开始有出血的情形，其理学检查发现右侧上颚颊前庭出现一无痛性肿胀，而磁振造影检查显示一实质性肿瘤充满于右侧上颚窦内。
