Dvelopment of Adhesive Bonding Agents for Tooth Substance : Dentinal Adhesive System without Acid Etching

在本研究中， 151种淀粉引物：A级引物（60重量%羟基甲基丙烯酸酯和40重量%分散的水）， 50种B级引物（50种0.5摩尔%氨基酸添加在A级引物中。相应地）， 50种C-primer（10wt%尖晶石二羟基二甲基丙烯酸酯被添加到50种B-primer中）和50种D-primer中（10wt%4-丙烯酸三甲基酸被添加到50种B-primer中），2种试验牙科结合剂被准备好。SEM观察、红外光谱和对A-、B-、C-和D-引物和试验和商业绑定代理进行了测试，并得出了以下结果。在SEM观察和对牙科表面的红外光谱治疗，对151种不同的引物而言，他们的表面找到了带有涂片帽和暴露的渗透性牙齿的牙科导管，以及所有的治疗都不存在于牙科中的去分化和去饱和的有机成分。作为使用A-、B-和C-引物进行试验性牙科绑定剂（含有10%的吡酸二氢二甲酸二甲酸酯）的粘合强度，A-、B-和C-引物分别使用2.5、2.5-6.0和6.4-10.8兆帕。在另一方，在使用C-primer和一个商业绑定代理人的情况下，以及D-primer和一个新的绑定代理人的情况下。C-和D-primers具有10.3-13.6和9.5- 30.2兆帕等效性。在使用D-引物和一种新的牙科绑定剂的案例中，发现了这种粘合剂机制，其粘合剂界面形成了一层具有高亲和力的牙科树脂粘合剂界面，并确定了与高亲和力相关的微标签，其结果表明，它们在牙科粘合剂上获得了高强度的价值。

In this study, 151 kinds of detin primers : A-primer (60wt% hydroxyethyl methacrylate・40wt% distillled water), 50 kinds of B-primers (50 kinds of 0.5mole% amino acids were added in A-primer. respectively), 50 kinds of C-primers (10wt% pynomellitic dianhydride dimethacrylate was added in 50 kinds of B-primers respectively) and 50 kinds of D-primers (10wt% 4-acryloxyethyl trimellitic acid was added in 50 kinds of B-primers respectively), and 2 kinds of trial dentinal bonding agents were prepared. SEM observations, Infrared spectrometry and shearing adhesive test of detinusing A-, B-, C- and D-primers and trial and commercial bonding agents were examined, and the following results were obtained.1. In SEM observations and IR spectra of dentin surfaces treated with151 kinds of primers respectively, their surfaces were found dentinal tubules with smear-capping and exposed peritubular dentins, and all treatments were not occured demineralization and denaturation inorganic components in dentin.2. As for adhesive strength of detin using A-, B- and C-primers a trial dentinal bonding agent (containing 10% pynomellitic dianhydride dimethacrylate), A-, B- and C-primers had 2.5,2.5-6.0 and 6.4-10.8 MPa respectively. On the other hand, in cases of using C-primers and a commercial bonding agent, and D-primers and a new bonding agent. C- and D-primers had 10.3-13.6 and 9.5-30.2MPa respectively.3. In cases of using D-primers and a new dentinal bondig agent, this adhesive mechanism was found that their adhesive interfaces had formed the layrs of dentin-resin adhesive interfaces consisting microtags with high affinity, their results were obtained values of high strength on dentinal adhesion.
