Concerning the relation between the fixation of the demineralized collagen layr of the dentin and the HEMA solution, the maintenance and fixation of the collagen fibers were possible with the use of water as solvent. When ethanol, benzene and 100% HEMA was used, the fixation did not occur. Applying the apatite included bonding agent to the surface pretreated with the above described HEMA/water produced primer, the infiltration and polymerization of the apatite included monomer among the collagen fibers (about 0.05-0.2 mum) could be evident in the SEM images. The adhesive strength between the 40% phosphoric acid, 30% HEMA treated dentin and apatite added bonding agent after 24 hours was 16.2 <plus-minus> 3.5 Mpa, and after the 20000 cycles heat stress was 15.9 <plus-minus> 4.2 Mpa. The control group (bonding agent without apatite) presented 14.6 <plus-minus> 3.8 Mpa and 9.8 <plus-minus> 2.4 Mpa, respe

关于牙本质脱矿胶原层的固定与HEMA溶液之间的关系，使用水作为溶剂可以维持和固定胶原纤维。当使用乙醇、苯和100% HEMA时，没有发生固定。将包含磷灰石的粘合剂施加到用上述HEMA/水产生的底漆预处理的表面上，包含磷灰石的单体在胶原纤维(约0.05-0.2μm)之间的渗透和聚合在SEM图像中可以是明显的。 40%磷酸、30%HEMA处理的牙本质和添加磷灰石的粘结剂24小时后的粘结强度为16.2±3.5Mpa，20000次循环后热应力为15.9±4.2Mpa。对照组（不含磷灰石的粘结剂）分别呈现 14.6 <正负> 3.8 Mpa 和 9.8 <正负> 2.4 Mpa
