Abstract

AIM: Assessment of the effectiveness of various pre-treatment techniques, i.e., Airborne particle abrasion (APA), Er, Cr: YSGG lasers (ECL), Rose Bengal (RB) activated via Low-level laser therapy (LLLT) on the repair bond strength (RBS) of resin matrix ceramics (RMC) bonded with different viscosity composites.

MATERIALS AND METHODS: RMC blocks were meticulously cut into 78 discs. All the discs were then randomly assigned to three separate groups based on the conditioning regime(n = 26): Group 1 (APA), Group 2 (ECL), and Group 3 (LLLT-RB). Five samples from each category were selected at random to assess Ra(n = 5). One prepared sample from each group underwent surface topography analysis and energy dispersive X-ray analysis (EDX) (n = 1). Each group was further categorized into two subgroups based on the type of composite resin used(n = 10). High viscosity micro-hybrid composite (A) and a low viscosity injectable composite (B) followed by artificial aging. RBS and failure mode were analyzed using a universal testing machine and stereomicroscope. The Ra and RBS data underwent comparison through a two-way ANOVA and post hoc Tukey test (p˂0.05).

RESULTS: The maximum Ra was exhibited by Group 2 (ECL) (1056.65 ± 0.029 µm) discs. Conversely, Group 3 (LLLT-RB) (753.31 ± 0.045 µm) conditioned samples demonstrated the minimum Ra. The highest bond strength score was recorded by Group 2B (ECL + Injectable) (10.63±0.19 MPa). In contrast, the lowest average bond strength value was noted in Group 3A (LLLT-RB + Microhybrid) (7.99±0.77 MPa).

CONCLUSION: ECL has the potential to serve as a hybrid ceramic surface conditioner, as it improves the surface roughness scores. Furthermore, low-viscosity injectable composites showed better performance than high-viscosity composites in achieving higher bond strength.

玫瑰孟加拉激活低能级激光预处理树脂基陶瓷及不同粘度复合材料粘接Er， Cr: YSGG修复强度和粗糙度

目的：评价空气颗粒磨损（APA）、Er、Cr: YSGG激光（ECL）、低水平激光治疗（LLLT）激活的Rose Bengal （RB）等预处理技术对树脂基陶瓷（RMC）与不同粘度复合材料结合后修复结合强度（RBS）的影响。材料和方法：RMC块被精心切割成78个圆盘。然后根据调理方案将所有椎间盘随机分为三组（n=26）： 1组（APA）， 2组（ECL）和3组（LLLT-RB）。每个类别随机抽取5个样本评估Ra（n=5）。每组各取1个制备样品进行表面形貌分析和能量色散x射线分析（n=1）。每组根据所使用的复合树脂类型进一步分为两个亚组（n=10）。高粘度微杂化复合材料(A)和低粘度可注射复合材料(B)，然后进行人工时效。采用万能试验机和体视显微镜对其进行分析。Ra和RBS数据通过双向方差分析和事后Tukey检验进行比较（p小于0.05）。结果：第二组（ECL）的Ra最大（1056.65±0.029µm）；相反，第3组（LLLT-RB）（753.31±0.045µm）条件样品的Ra最小。结合强度评分最高的是2B组（ECL + Injectable）（10.63±0.19 MPa）。相比之下，3A组（LLLT-RB + Microhybrid）的平均结合强度值最低（7.99±0.77 MPa）。结论：ECL具有作为混合陶瓷表面调理剂的潜力，因为它可以提高表面粗糙度评分。此外，低粘度可注射复合材料在获得更高的粘结强度方面表现出比高粘度复合材料更好的性能。
