目标.已开发出美学桩以最大化美学矫正的基础。本研究旨在评价硅烷对三种纤维增强树脂桩（纤维桩）粘结强度的影响。对54颗离体上颌中切牙和尖牙进行根管治疗。D.T.使用相应制造商提供的树脂粘合剂系统插入Light Post（DT，Bisco）、FRC Postec（FR，Ivoclar Vivadent）和ParaPost Fiber白色（PP，Coltene/Whaledent）。对于每组中的一半样本，使用硅烷溶液（Monobond S，Ivoclar Vivadent）处理纤维桩。对每个牙根的三个不同部分进行推出试验，以测量粘结强度。统计分析采用方差分析和Bonferroni事后检验，P <0.05。硅烷的使用没有导致任何统计学上的显着差异，在任何水平的根。硅烷不会导致每个立柱的粘结强度（MPa）有任何显著差异。当合并数据时，使用硅烷不会导致统计学显著性差异（P > 0.403）：无硅烷= 12.7 +/- 8.4;硅烷= 14.1 +/- 7.0。根冠1/3（17.5 +/- 6.7）的粘结强度在统计学上分别大于中1/3（12.9 +/- 6.8）和根尖1/3（9.8 +/- 7.3），P < 0.002和P < 0.0001。中三分之一和顶端三分之一的粘结强度在P > 0.07时没有统计学显著差异。在P > 0.417时，桩的类型没有导致统计学上显著的粘结强度差异：DT = 14.7 +/- 6.8 MPa; FR = 13.3 +/- 6.6 MPa; PP = 12.2 +/- 6.6 MPa。显著性。使用硅烷偶联剂并没有增加本研究中使用的三种纤维桩的推出粘结强度。所有桩均以相同的强度与根面牙本质粘结。在牙根的最冠状水平处，粘结更可预测。(C)2005年，牙科材料学院。由爱思唯尔有限公司出版。保留所有权利。
Objectives. Esthetic posts have been developed to maximize the foundation of esthetic restorations. The purpose of this study was to evaluate the effect of silane on the bond strength of three fiber-reinforced resin posts (fiber posts).Methods. Fifty-four extracted human maxillary central incisors and canines were endodontically treated. D.T. Light Post (DT, Bisco), FRC Postec (FR, Ivoclar Vivadent), and ParaPost Fiber White (PP, Coltene/Whaledent) were inserted using the resin adhesive system provided by the respective manufacturer. For half of the specimens in each group, the fiber posts were treated with a silane solution (Monobond S, Ivoclar Vivadent). A push-out test was performed on three different sections of each root to measure bond strengths. Data were analyzed with ANOVA and Bonferroni's post hoc test at P < 0.05.Results. The use of silane did not result in any statistically significant difference at any level of the root. Silane did not result in any significant different bond strengths (MPa) for each of the posts. When the data were pooled, the use of silane did not result in statistically significant different bond strengths at P > 0.403: No silane = 12.7 +/- 8.4; Silane = 14.1 +/- 7.0. The coronal third of the root (17.5 +/- 6.7) resulted in statistically greater bond strengths than the medium third (12.9 +/- 6.8) and than the apical third (9.8 +/- 7.3) at P < 0.002 and P < 0.0001, respectively. The medium third and the apical third resulted in no statistically significant different bond strengths from each other at P > 0.07. The type of post did not result in statistically significant different bond strengths at P > 0.417: DT = 14.7 +/- 6.8 MPa; FR = 13.3 +/- 6.6 MPa; PP = 12.2 +/- 6.6 MPa.Significance. The use of a silane coupling agent did not increase the push-out bond strengths of the three fiber posts used in this study. All posts bonded to root dentin at the same magnitude. Bonding is more predictable at the most coronal level of the root. (C) 2005 Academy of Dental Materials. Published by Elsevier Ltd. All rights reserved.
