The important step for securingdeep penetration into the fissures of thesealant may be achieved by selecting oflow-viscous epoxy-resin as raw ma-terial, since the viscosity of the self-curing sealant affects its properties toa large extent. In this study the CGY-331 and E-51 epoxy resins were usedto synthesize the EM resins.All of themcontain about 25 percent MMA. It isfound that the viscosity of the formeris 120-260 centipoise at 25℃, and thelatter 400 centipoise at 25℃.Thus EMresin synthesized by CGY-331...

The important step for securingdeep penetration into the fissures of thesealant may be achieved by selecting oflow-viscous epoxy-resin as raw ma-terial, since the viscosity of the self-curing sealant affects its properties toa large extent. In this study the CGY-331 and E-51 epoxy resins were usedto synthesize the EM resins.All of themcontain about 25 percent MMA. It isfound that the viscosity of the formeris 120-260 centipoise at 25℃, and thelatter 400 centipoise at 25℃.Thus EMresin synthesized by CGY-331 epoxy isselected as the main component of thesealant.The tags of the resin penetratedinto the etched enamel are measuredunder SEM and found to be as long as13μm. The sealing effect on the fis-sures is excellent .The structure is similarto Bis-GMA by infra-red spectrographyanalysis. The resin can be cured within1-1~(1/2) min. The adhesive strength onetched enamel of the resin after curingis 100-170 kg/cm~2. The solubilities ofthe sealant in distilled water, 0.1NNaOH, 0.1N lactic acid and 5% aceticacid are 0.02-0.05mg/cm~2. It containsvolatile materials in less than 3%.After acetone extraction the sampleretains more than 95% of its weight.All these show a high degree of curing.The chemical and physical propertiesare stable. The other related clinical.tests comply with the requirements ofclinical practice. Acute toxic effects was tested bytubing of the mixture of sealant powderand tween in a dosage of 10g/kg bodyweight into the stomach of healthysmall rats. No toxic effect or death wasobseryed. A subacute intoxication testwas carried out on white rats. Aftercontinuous feeding of the same mixture in dosages of 2g/kg body weight perday for 45 days, no apparent differencebetween the experimental and controlswas observed in the activities, bodyweight growth, routine blood examina-tions, hepatic and renal functions andthe histopathologic pictures. Clinically, the sealant was appliedon 968 non-carious first permanentmolars of 7-9 year-old children. Theintact retention rate after 1, 2, 3 yearswas 83.78%, 66.93%, 55.37% and cari-es incidence was reduced up to 92.31%,93.10%, 83.47% respectively. No sig-nificant difference was shown betweenthe retention rates of different teeth,but the caries was reduced to 86.36%for lower teeth and 75.76% for theuppers (P<0.01). This is probablyrelated to the higher incidence for thelowers. Caries occur more frequentlyin pits than in fissures.The most fre-quent occurrence is in the central pit,for example, in the upper teeth thepercentage of occurrence is 66.67, andin the lower teeth 46.15. This showsthat the pits are the most susceptibleareas to caries, and it is worthy ofnotice for the sake of preventivemeasures.

作者选用CGY-331环氧树脂为原料,合成EM树脂,经筛选配制成EM自凝防龋剂。该剂具有粘度低,易渗透,固化速度快,固化程度高,耐介质性能良好,临床应用较方便等特点。经动物毒性实验证明,对机体基本无毒害。试用于7~9岁1039名小学生作连续观察,三年后复查到的968颗经涂布的无龋第一恒磨牙,其龋齿降低率为83.47%。

In this paper two sealants were made refer to the composition of Concise (Light-cured and autopolymerised, 3M Dental Products, U. S. A). The Laboratory characteristics test results indicated that , there were no differences in bonding characteristics and water sorption and abrasion between the self-made and Consise sealants. As for physical characteristics, the surface hardness values of the self-made sealants (P<0. 01). The self-madeautopolymerised sealants were not as good as the Concise...

In this paper two sealants were made refer to the composition of Concise (Light-cured and autopolymerised, 3M Dental Products, U. S. A). The Laboratory characteristics test results indicated that , there were no differences in bonding characteristics and water sorption and abrasion between the self-made and Consise sealants. As for physical characteristics, the surface hardness values of the self-made sealants (P<0. 01). The self-madeautopolymerised sealants were not as good as the Concise in compressive strength. In diam-eteral tensile strength, the self-made light-cured better than the Concise autopolymerised. On the whole, the self-made and Concise sealants were similar in their properties.

参照美国封闭剂Concise配方组成,自制了可见光固化和自凝两种封闭剂.实验室研究结果表明,在粘结性能、吸水性和磨耗率方面,自制封闭剂和Concise无差异.在表面硬度值方面,两种自制封闭剂均极显著低于相应固化方式的Concise(P<0.01).在抗压强度方面,自制光固化封闭剂与光固化Concise无差异;自制自凝封闭剂则显著低于自凝Concise.在径向抗张强度方面,自制光固化封闭剂显著高于光固化Concise;而自制自凝封闭剂极显著低于自凝Concise.总体评价是:自制封闭剂的性能和Concise大体相似.

Two kinds of diluent were used:3G(triethyleneglycol dimethacrylate) and EDMA(ethyleneglycol dimethacrylate). 12 sealants were designed using each diluent with different ratios of 40%,50%, 55%, 60%, 70% and 80% of the weights of the sealants respectively. The characteristics test results indicated that, 3G is a better diluent than EDMA and that different ratios of diluent(ranging from 40% to 60% by the weight of the sealants) did not significantly affect the characteristics of the sealants....

On the whole, the sealants with the ratios of diluent ranging from 40-50% are the best.

选用3G(二甲基丙烯酸二缩三乙二醇酯)、EDMA(甲基丙烯酸乙二醇酯)两种稀释剂,并设计40%、50%、55%、60%、70%、80%6种不同重量比例封闭剂配方,测定粘结性能(包括粘度值、渗透性、抗剪粘结强度)、机械性能(包括表面硬度、抗压强度、径向抗张强度)、吸水性和耐磨性。结果表明:3G作稀释剂优于EDMA,不同稀释剂比例(在40%~60%范围内)对封闭剂性能影响不大,总体评价,以40%~50%配方比例为最好。
