Tricalcium silicate cements can be used for pulp capping, pulpotomies, apical barrier formation in teeth with open apices, repair of root perforations, regenerative endodontics, and root canal filling. The aim of this study was to evaluate and compare the discoloration potential of 3 different tricalcium cements using a bovine tooth model.
Forty bovine anterior teeth have been used for the study. Crowns separated from the roots were randomly divided into 4 groups: the BioAggregate (IBC, Vancouver, Canada) group, the Biodentine (Septodont, Saint Maur des Fosses, France) group, the mineral trioxide aggregate Angelus (Angelus, Londrina, PR, Brazil) group, and the only blood group. Materials have been placed to the standardized cavities on the lingual surfaces of the crowns, and their contact with blood has been provided. The color values of the samples were measured with a digital tooth shade determinator (VITA Easyshade; VITA Zahnfabrik, Bad Sackingen, Germany) before the placement of the materials, after the placement of the materials, in the 24th hour, in the first week, in the first month, in the third month, and in the first year. The mean value of all groups was compared using the Tukey multiple comparison test (α = 0.05).
All groups displayed increasing discoloration during a period of the first year. The "only blood group" showed the highest color change values, and it was followed as BioAggregate, mineral trioxide aggregate Angelus, and Biodentine, respectively. Statistically significant differences were found for Biodentine when compared with the only blood and BioAggregate groups (P < .05).
Considering the results of the study, Biodentine is found to have the least discoloration potential among the tested materials.
硅酸三钙水门汀可用于盖髓术、活髓切断术、根尖未发育完成牙齿的根尖屏障形成、根管穿孔修复、再生性牙髓治疗以及根管充填。本研究的目的是使用牛牙模型评估和比较3种不同硅酸三钙水门汀的变色潜能。
本研究使用了40颗牛前牙。将牙冠与牙根分离后随机分为4组：BioAggregate（IBC，加拿大温哥华）组、Biodentine（Septodont，法国圣莫尔代福塞）组、矿物三氧化物凝聚体Angelus（Angelus，巴西隆德里纳）组和单纯血液组。将材料放置在牙冠舌面的标准化窝洞中，并使其与血液接触。在材料放置前、放置后、第24小时、第一周、第一个月、第三个月和第一年，使用数字牙齿比色仪（VITA Easyshade；VITA齿科材料有限公司，德国巴特萨克根）测量样本的颜色值。使用Tukey多重比较检验（α = 0.05）比较所有组的平均值。
在第一年期间，所有组的变色情况均有所增加。“单纯血液组”的颜色变化值最高，其次分别是BioAggregate、矿物三氧化物凝聚体Angelus和Biodentine。与单纯血液组和BioAggregate组相比，Biodentine有统计学显著差异（P < 0.05）。
考虑到研究结果，发现Biodentine在所测试的材料中变色潜能最小。
