This study was described the structure and function of long junctional epithelium (LJE) formed on the root surfaces following periodontal surgery.1. Structural Changes of LJE After Plaque InfectionThe materials were premolars of 5 beagle dogs. Plaque accumulation was carried out to the LJE established on the denuded cementum surfaces. It was demonstrated that the findings of destructing LJE and deepening gingival sulcus were same as JE clinically, light and electron microscopycally following plaque infection. It was suggested that LJE was functioned effectively for barrier to the irritant as same as JE.2. Structural changes of LJE after application of irritantsThe materials were rats first molars. Application of PGE_2 (0.5mg/ml) and ET (0.2mg/ml, E. coli) were performed to the LJE established on the denuded dentin surfaces. It was recognized that the findings of destructing LJE and deepening gingival sulcus were as same as JE light and electron microscopycally after applications of PGE_2 and ET. These finding indicated that LJE was functioned effectively for barrier and tissue repair as same as JE.

这项研究被描述了牙周手术后的根表面上形成的长连接上皮（LJE）的结构和功能。1。牙菌斑感染后LJE的结构变化是材料是5只小狗狗的前磨牙。将牙菌斑的积累进行到在裸露的骨骼表面上建立的LJE。事实证明，破坏LJE和加深牙龈沟的发现与牙菌斑感染后的临床，光和电子显微镜相同。有人提出，LJE对与JE.2一样的刺激物的障碍有效起作用。施用刺激物后LJE的结构变化材料是大鼠的第一磨牙。对在裸露的牙本质表面上建立的LJE进行了PGE_2（0.5mg/mL）和ET（0.2mg/ml，大肠杆菌）的应用。人们认识到，在PGE_2和ET应用后，破坏LJE和加深牙龈沟的发现与JE光和电子显微镜一样。这些发现表明，LJE对屏障和组织修复有效起作用，与JE一样。
