Abstract

OBJECTIVE

This study aimed to compare dentin bond durability under different degradation conditions between two etch-and-rinse (ER) systems and a universal adhesive in ER mode.

METHOD

This study used a universal adhesive [Scotchbond Universal (SU)], a three-step ER adhesive [Scotchbond Multi-Purpose Plus (SM)], and a two-step ER adhesive [Single Bond Plus (SB)]. A phosphoric acid-etching agent was applied to bovine dentin prior to the application of either a primer or the adhesive. After acid etching, bonding procedures were conducted. The specimens were divided into three group classes: (1) subjected to 10,000, 30,000, or 50,000 thermal cycles (TC); (2) stored in distilled water at 37 °C for 6 months or 1 year (WS); and (3) stored in distilled water for 24 h (baseline). Shear bond strength (SBS) tests were conducted.

RESULTS

SB showed a higher baseline SBS than the other adhesives. Defining the baseline SBS value for each adhesive system as 100%, TC groups ranged from 56.1 to 70.3% for SM, from 98.4 to 103.7% for SB, and from 120.3 to 126.7% for SU. WS groups ranged from 66.2 to 71.4% for SM, from 98.1 to 103.3% for SB, and from 102.5 to 118.1% for SU.

CONCLUSIONS

Although SB showed relatively stable dentin bond performance under all degradation conditions, SM showed decreased dentin SBS with prolonged degradation. SU did not show any significant decrease in SBS from the baseline under any degradation condition.

CLINICAL RELEVANCE

The universal adhesive showed comparable adhesive performance with the two-step ER adhesive.

摘要

目的

本研究旨在比较两种全酸蚀（ER）系统和一种通用型 ER 模式下的通用型胶粘剂在不同降解条件下的牙本质粘结耐久性。

方法

本研究使用一种通用型胶粘剂[Scotchbond Universal（SU）]、一种三步 ER 胶粘剂[Scotchbond Multi-Purpose Plus（SM）]和一种两步 ER 胶粘剂[Single Bond Plus（SB）]。在应用底漆或胶粘剂之前，将磷酸酸蚀剂应用于牛牙本质。酸蚀后进行粘结程序。将标本分为三组：（1）经受 10000、30000 或 50000 次热循环（TC）；（2）在 37°C 的蒸馏水中储存 6 个月或 1 年（WS）；和（3）在蒸馏水中储存 24 小时（基线）。进行剪切粘结强度（SBS）测试。

结果

SB 的基线 SBS 高于其他胶粘剂。将每种胶粘剂系统的基线 SBS 值定义为 100%，TC 组 SM 的范围为 56.1%至 70.3%，SB 的范围为 98.4%至 103.7%，SU 的范围为 120.3%至 126.7%。WS 组 SM 的范围为 66.2%至 71.4%，SB 的范围为 98.1%至 103.3%，SU 的范围为 102.5%至 118.1%。
