Abstract

Objectives: In parallel with the 36-month clinical evaluation of a universal adhesive, tooth-composite bond failure was assessed by tomography.

Methods: In 55 patients, three non-carious cervical lesions (NCCLs) each were restored with Filtek^TM Supreme XTE (3M) using the universal adhesive Scotchbond™ Universal Adhesive (SBU, 3M) in the self-etch (SE) or selective enamel-etch (SEE) mode or by OptiBond™ FL (OFL, Kerr, reference, randomization). Immediately after restoration placement (T0) and in parallel with the clinical assessments (FDI criteria) at 6, 12, 24, and 36 months (M), the restorations were imaged by optical coherence tomography (OCT) to quantify interfacial adhesive defects (ADs; 14 days, clinical only). Cumulative failure rates (CFRs) and means of ADs were statistically analyzed.

Results: From six to 36M, CFRs were lower in the SBU groups vs. OFL (p_i ≤ 0.004). Compared to SBU-SE or OFL, SBU-SEE resulted in reduced marginal staining (≥ 12M; p_i: 0.002 - 0.727) and increased marginal adaptation (≥ 12M; p_i: 0.001 - 0.629). Increased ADs appeared on the enamel with SBU-SE vs. SBU-SEE and OFL (T0 - 36M; p_i ≤ 0.001/0.048) and with OFL vs. SBU-SEE (≥ 6M; p_i ≤ 0.025). At dentin/cement less defects appeared using SBU-SEE vs. SBU-SE (≥ 6M) or OFL (≥ T0, p_i ≤ 0.0115), and fewer in the SBU-SE vs. OFL group (≥ T0, p_i ≤ 0.001). Before restoration loss, the adhesive defects on the dentin/cement were increased (p_i ≤ 0.05).

Conclusions: Clinical assessments and OCT-based analyses were consistent. In terms of bond failure, however, the groups already differed upon restoration placement, with reproducible substrate-specific differences becoming apparent.

Clinical significance: The universal adhesive Scotchbond™ Universal Adhesive in SEE mode performed most favorably. Interfacial adhesive defects detectable by OCT reliably predict the performance of a restoration system. #DRKS00011084, http://www.drks.de/DRKS00011084, 30.09.2016.

一项为期三年的临床试验用OCT评价一种通用粘接剂。

目的：在对通用粘接剂进行36个月的临床评估的同时，通过断层扫描评估牙齿-复合粘接剂的失效。方法：在55例患者中，使用FiltekTM Supreme XTE （3M）修复3个非龋齿宫颈病变（ncls），使用通用粘合剂Scotchbond™通用粘合剂（SBU, 3M）在自蚀刻（SE）或选择性搪瓷蚀刻（SEE）模式或OptiBond™FL （OFL, Kerr，参考，随机化）。在修复体放置（T0）后，并在6、12、24和36个月(M)进行临床评估（FDI标准）的同时，通过光学相干断层扫描（OCT）对修复体进行成像，以量化界面粘接剂缺陷（ADs； 14天，仅临床）。统计分析累积失效率（CFRs）和ADs平均值。结果：从6到36M， SBU组的CFRs低于OFL组（pi≤0.004）。与SBU-SE或OFL相比，SBU-SEE减少了边缘染色（≥12M, pi: 0.002 - 0.727），增加了边缘适应（≥12M, pi: 0.001 - 0.629）。SBU-SE组与SBU-SEE组、OFL组（T0 ~ 36M, pi≤0.001/0.048）、OFL组与SBU-SEE组（≥6M, pi≤0.025）牙釉质上ad增加。与SBU-SE（≥6M）或OFL（≥T0, pi≤0.0115）相比，SBU-SE组出现的牙本质/水泥缺陷较少（≥T0, pi≤0.001），SBU-SE组与OFL组出现的缺陷较少（≥T0, pi≤0.001）。修复丢失前，牙本质/骨水泥的粘接剂缺陷增加（pi≤0.05）。结论：临床评估和基于oct的分析是一致的。然而，在结合失败方面，两组在修复放置上已经有所不同，可重复的基质特异性差异变得明显。临床意义：万能粘合剂Scotchbond™万能粘合剂在SEE模式下表现最好。用OCT检测界面粘接剂缺陷可以可靠地预测修复系统的性能。#DRKS00011084, http://www.drks.de/DRKS00011084, 30.09.2016。

期刊介绍： The Journal of Dentistry has an open access mirror journal The Journal of Dentistry: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The Journal of Dentistry is the leading international dental journal within the field of Restorative Dentistry. Placing an emphasis on publishing novel and high-quality research papers, the Journal aims to influence the practice of dentistry at clinician, research, industry and policy-maker level on an international basis. Topics covered include the management of dental disease, periodontology, endodontology, operative dentistry, fixed and removable prosthodontics, dental biomaterials science, long-term clinical trials including epidemiology and oral health, technology transfer of new scientific instrumentation or procedures, as well as clinically relevant oral biology and translational research. The Journal of Dentistry will publish original scientific research papers including short communications. It is also interested in publishing review articles and leaders in themed areas which will be linked to new scientific research. Conference proceedings are also welcome and expressions of interest should be communicated to the Editor.
