Abstract

Statement of problem: There is a reduction of dentin bonding strength when the bonding procedure is carried out immediately after bleaching with peroxides. Purpose: The aim of this study is to evaluate a proper time interval for in-office bleaching technique using 35% hydrogen peroxide. Material and methods: Fifty extracted non-caries human third molars were used in this study. Buccal enamel of each tooth was removed and polished by 600 grits silicone carbide paper. They were randomly divided into five groups and bleached 35% hydrogen peroxide except control group. All groups were bonded with Single Bond/Z 350 after each time intervals ; Group-A: control, no bleaching treatment. Group-B: resin bonding immediately after bleaching. Group-C: resin bonding 1day after bleaching. Group-D: resin bonding 2 days after bleaching. Group-E: resin bonding 7days after bleaching. Shear bond strengths were measured with a cross-head speed of 1.0 mm/min using an Instron machine. The data of results were statistically analyzed by analysis of variance(ANOVA) and Tukey multiple comparison test.(P=.05) Results: There were significant decreases in mean shear strength in immediately bonding group after bleaching. The reduction of bond strengths was 78% compared with the group of no bleaching treatment. Group C showed the recovery of 51%, and Group D showed recovery of 63%. Both of them have no statistical difference with non-bleaching group. Group E showed no statistical difference with no bleaching treatment group. Conclusion: Dentin bonding strength is significantly reduced when bonding is performed immediately after bleaching for in-office bleaching regimens using 35% hydrogen peroxide, and increases as time goes by. One week of elapsed time between bleaching and resin bonding significantly increases bonding strengths for the in-office bleaching technique.

연구목적: 본 연구에서는 35% 과산화수소를 사용하는 전문가 미백 술식에서 레진 접착제의 접착력 회복을 위한 유예 기간을 비교하고자 한다. 연구 재료 및 방법:3M사의 Single Bond와 Z350을 이용하여 미백 직 후, 1일후, 2일후, 일주일 후의 시간 차이를 두고 상아질에 접착된 복합 레진의 전단 결합 강도를 측정하여 다음과 같은 결과를 얻었다. 결과: 미백 처리 직 후의 상아질 전단 결합 강도는 다른 군에 비해 유의하게 낮았으며(P<.05), 미백 처리 전에 비해 약 78%의 결합력 감소를 보였다. 미백 처리 1일 후의 상아질 결합 강도는 미백 직 후 감소된 결합력의 51%에 이르는 회복을 보였으며, 2일 경과한 시편에서는 감소된 결합력의 63%가 회복되었다. 두 군은 미백 직 후에 비해 유의하게 큰 회복력을 보였으나, 두 군 간에는 유의한 차이가 없었다(P>.05). 미백 처리 후 결합력의 회복은 초기 24시간 이내에 급격히 일어나며 그 이후에는 서서히 일어나는 것으로 사료된다. 미백 일주일 후의 시편은 미백 처리 전에 비해97%에 이르는 결합력을 보이며 두 군 간에는 유의한 차이가 없었다(P>.05). 결론: 그러므로35% 과산화수소를 적용하는 전문가 미백 술식에서는 1주일간의 유예기간을 두고 복합 레진 접착술을 시행하는 것이 적절할 것으로 사료된다.
