Abstract

Aim: To evaluate the shear bond strength of pure tricalcium silicate-based cement (Biodentine) to Cention N between two maturation times of Biodentine, namely 12 minutes and 2 weeks. Materials and Methods: 30 acrylic blocks with a hole (3 mm in diameter and 1.5 mm in height) were prepared. Biodentine was mixed according to the manufacturer’s instructions and placed into the holes. The Samples were randomly divided into two groups. In group 1, Cention N was bonded to the Biodentine after 12 mins; in group 2, Cention N was bonded to Biodentine after 2 weeks. A plastic cylinder of height and diameter 2 mm was used to place Cention N over the Biodentine. A universal testing machine was used to measure the shear bond strength of the specimen. Data was analysed using SPSS V15.0. South Asia, Bangalore. Independent sample t-test was applied to compare the mean of the maximum compressive stress of the two groups. Result: Group 2 demonstrated significantly higher shear bond strength values compared to group 1. Lower shear bond strength testing values were observed when Cention N was bonded to an initially set Biodentine. Conclusion: The maturation period of Biodentine has a significant impact on its shear bond strength to Cention N. It is advisable to place the final overlying restoration after waiting for a duration of two weeks to allow the Biodentine maturation to take place.
成熟时间对碱土修复材料与纯硅酸三钙基水泥剪切结合强度的影响:体外实验研究
目的:评价纯硅酸三钙基水泥(Biodentine)在两个成熟时间(即12分钟和2周)与Cention N的剪切结合强度。材料和方法:30块带孔丙烯酸块(3 直径mm,1.5 高度为mm)。根据制造商的说明混合生物牙本质,并将其放入孔中。将样本随机分为两组。在第1组中,Cention N在12分钟后与生物牙本质结合;在第2组中,Cention N在2周后与Biodentine结合。高度和直径为2的塑料圆柱体 mm将Cention N放置在Biodentine上。使用万能试验机测量试样的剪切结合强度。使用SPSS V15.0对数据进行分析。南亚,班加罗尔。采用独立样本t检验来比较两组的最大压缩应力平均值。结果:与第1组相比,第2组表现出显著更高的剪切结合强度值。当Cention N结合到初始设置的Biodentine时,观察到较低的剪切结合强度测试值。结论:生物牙本质的成熟期对其与Cention N的剪切结合强度有显著影响。建议在等待两周后放置最后的上覆修复体,以使生物牙本质成熟。

期刊介绍: It is a journal aimed for research, scientific facts and details covering all specialties of dentistry with a good determination for exploring and sharing the knowledge in the medical and dental fraternity. The scope is therefore huge covering almost all streams of dentistry - starting from original studies, systematic reviews, narrative reviews, very unique case reports. Our journal appreciates research articles pertaining with advancement of dentistry. Journal scope is not limited to these subjects and is more wider covering all specialities of dentistry follows: Preventive and Community Dentistry (Dental Public Health) Endodontics Oral and Maxillofacial Pathology Oral and Maxillofacial Radiology Oral and Maxillofacial Surgery (also called Oral Surgery) Orthodontics and Dentofacial Orthopaedics Periodontology (also called Periodontics) Pediatric Dentistry (also called Pedodontics) Prosthodontics (also called Prosthetic Dentistry) Oral Medicine Special Needs Dentistry (also called Special Care Dentistry) Oral Biology Forensic Odontology Geriatric Dentistry or Geriodontics Implantology Laser and Aesthetic Dentistry.
