Barbituric acid 개시계 레진의 치질 접착성에 미치는 가교제의 영향
나환욱,이은경,김교한,강인규 대한치과기재학회 2001 대한치과재료학회지 Vol.28 No.2
Degree of polymerization, surface hardness and tensile bond strength of the bonding resin were carried out to examine the effect of crosslinking agent, triethylene glycol dimethacrylate(TEGDMA), on the adhesion of barbituric acid-initiated resin to dentin. As the results, degree of conversion and surface hardness increased with increasing the concentration of TEGDMA. Tensile bond strength of the resin increased with increasing the concentration of TEGDMA up to 6 wt% and, thereafter, decreased.

Dentin adhesion was studied on sandblasted dentin with 4-META/MMA-TBB resin. The effect of change of air pressure, with or without pretreatment and primer on tensile bond strength, was mainly investigated. In the effect of air pressure at sandblast treatment, the higher pressure showed the increase of tensile bond strength. The pretreatment with 10-3 sloution after sandblast treatment increased tensile bond strength in the almost conditions. Application of primer also increased the tensile bond strength, confirmed the effect of primer application after sandblast treatment. Alumina particle was not found on the dentin surface in the SEM and EDAX examination.
