  • Objectives: This study was performed to determine whether the combined use of one-bottle self-etch adhesives and composite resins from same manufacturers have better bond strengths than combinations of adhesive and resins from different manufacturers. Materials and Methods: 25 experimental micro-shear bond test groups were made from combinations of five dentin adhesives and five composite resins with extracted human molars stored in saline for 24 hr. Testing was performed using the wire-loop method and a universal testing machine. Bond strength data was statistically analyzed using two way analysis of variance (ANOVA) and Tukey's post hoc test. Results: Two way ANOVA revealed significant differences for the factors of dentin adhesives and composite resins, and significant interaction effect (p < 0.001). All combinations with Xeno V (Dentsply De Trey) and Clearfil $S^3$ Bond (Kuraray Dental) adhesives showed no significant differences in micro-shear bond strength, but other adhesives showed significant differences depending on the composite resin (p < 0.05). Contrary to the other adhesives, Xeno V and BondForce (Tokuyama Dental) had higher bond strengths with the same manufacturer's composite resin than other manufacturer's composite resin. Conclusions: Not all combinations of adhesive and composite resin by same manufacturers failed to show significantly higher bond strengths than mixed manufacturer combinations.

  • To evaluate the micro-shear bond strength of current adhesive systems to cervical and mid-coronal enamel. Materials and Two commercially available resin adhesives were investigated; a self-etching primer system(Clearfil SE Bond, Kyraray) and a one-bottle adhesive system(Single Bond, 3M) intended for use with the total-etch wet-bonding technique were employed. Two regions of enamel, cervical and mid-coronal regions, were chosen from the buccal surface of extracted molars and were then bonded with each adhesive system and submitted to the micro-shear bond test.(중략)

  • 본 연구는 자가부식 접착제의 치질로의 침투와 레진 tag 형성을 알아보고 부가적인 산부식이 레진 tag 형성에 미치는 효과를 관찰하기 위하여 계획되었다. 3종의 자가부식 접착제(SE bond, AQ bond and L Pop)와 one bottle adhesive(Single bond)를 사용하였고 발거한 구치로 교합면 법랑질과 상아질 시편을 제작하였으며 각 군당 5개씩 네 개의 군으로 나눈 총 20개의 시편을 양분하여 각각 접착제를 적용하기 전 35% 인산으로 산부식하거나 산부식처리하지 않았으며 이후 레진을 적용시키고 중합하였다. 시편은 Silverstone microtome으로 절단한 후 HCl 용액과 NaOCl 용액으로 처리하고 건조시킨 후 이온으로 피복하였으며 주사전자현미경으로 관찰하여 다음과 같은 결과를 얻었다. 1. 부가적 산부식 처리한 상아질은 모든 자가부식 접착제군에서 산부식하지 않은 상아질보다 resin tag의 길이와 두께가 증가하는 것이 관찰되었다. 2. 법랑질에서는 L Pop을 제외하고 부가적 산부식한 군에서 레진 tag의 두께가 산부식하지 않은 군보다 컸고 보다 명확한 부식양상을 관찰할 수 있었다. L Pop에서는 부식법랑질과 비부식법랑질간의 차이가 없었다. 본 연구의 결과는 자가부식형 접착제가 법랑질을 부식시키지 않고 상아세관으로 침투하는 정도가 산부식군에 미치지 못하다는 것을 의미한다. 이와 관련하여 접착강도와 미세누출 및 레진 tag 형태에 대한 부가적 연구가 필요할 것이다.

  • The bond strength is one of the most important factor in establishing long-term success of esthetic restorative dentistry. So, various restorative materials have been introduced to improve the esthetic and physical properties. Ormocer (organically modified ceramic) was developed as a result of such efforts. This study was performed to compare the shear bond strength of ormocer based adhesive with that of existing dentin adhesive. In this study $Admira^{(R)}$ and $Admira^{(R)}$ bond of the ormocer system are grouped together for ADM, Single $Bond^{(R)}$ which is an one-bottle adhesive and Z-250TM which is hybrid composite resin of BIS-GMA system for SIN, and $Definite^{(R)}$ of ormocer and Etch & $Prime^{(R)}$ 3.0 which is a self etching priming/ bonding agent for ETC. The results of this study were as follows. : (1) In the comparison of shear bond strength according to different adhesive system, shear bond strength was increased in the order of ETC group, SIN group, ADM group. There was no significant difference between ADM group and SIN group. However, there was a significant level of difference between ADM and ETC groups as well as SIN and ETC groups( p<0.05). (2) Examination by a scanning electron microscope showed a well established hybrid layer and resin tag in both ADM group and SIN group, while ETC group showed a minimal formation of the hybrid layer when compared with ADM and SIN groups. From the above results, it may be reasonable to start the clinical application of ormocer system, and it is recommended that ormocer system should be used along with an ormocer based adhesive because ormocer system showed the lower shear bond strength when it used with other existing self etching priming/bonding agent. The self etching priming/bonding agent showed relatively low shear bond strength, and it is considered that the further study should be needed.
