摘要

此研究乃探討五種複合玻璃離子體，以五種不同表面處理方式產生的鍵結強度。二種複合樹脂及一種傳統玻璃離子體作為對照組。
結果顯示，複合玻璃離子體比傳統玻璃離子體在琺瑯質上有更強的鍵結強度。所有經過酸蝕的複合玻璃離子體之鍵結強度均大於10MPa，其中二種複合玻璃離子體，Dyract及Aduance，經過酸蝕，其鍵結強度和複合樹脂相近。這顯示，Dyract和Aduance可被作為常規的矯正器黏著劑。
此研究亦顯示，除了一種例外，所有的複合玻璃離子體均需酸蝕以達到10MPa鍵結強度。這個例外，Aduance以底劑處理，可不須酸蝕而到達10MPa。由此結果可看出，將來某些矯正黏著劑可能不需酸蝕。

In this study, the shear bond strength of five hybrid glass ionomer materials to bovine enamel using five different enamel surface treatments was evaluated. Two composite resins and one conventional glass ionomer were used as control groups.
The results showed that hybrid glass ionomers bond much more strongly to enamel than do the conventional glass ionomers. All the acid etched hybrid glass ionomers had bond strengths higher than 10 Mpa. Two hybrid glass ionomers, Dyract and Advance, bonded using the acid etch technique had a similar bond strength as the composite resin bonding agent, Concise. The results suggested that Dyract and Advance could be used as a routine orthodontic bonding agent.
This investigation demonstrated that all but one of the hybrid glass ionomers required acid etching to reach 10 MPa. The exception, Advance treated with primer, had a bond strength higher than 10 MPa. This result suggested that in the future some materials may not require acid etching.
