To compare coronal tooth discoloration obtained by different endodontic materials-MTA Plus, Bio MTA+, Biodentine.
Pulps in 30 caries-free mandibular and maxillary intact human premolars and molars scheduled for extraction for periodontally compromised reasons were mechanically exposed and allocated to each of the three groups, MTA Plus, Biodentine and Bio MTA+. After the pulpotomy procedure, the base of resin-modified GIC was given and the teeth were filled with composite resin. After extraction, the teeth were stored in artificial saliva and spectrophotometer analysis done eventually at 1, 7, 30, and 60 days later. Images of all teeth were recorded at each interval using a digital camera and the ∆ values for all specimen at interval were recorded and compared.
Majority of the specimens showed discoloration after placement of MTA Plus, Biodentine, and Bio MTA+. The statistical analysis showed significant differences between the MTA Plus, Bio MTA+, and Biodentine experimental groups during the observation period.
Under the states of this study, compared to Bio MTA+ and MTA Plus, Biodentine created significantly less discoloration.
Mineral trioxide aggregate materials lead to higher amount of discoloration on the tooth surface than Biodentine. Hence, Biodentine should be the material of choice for use in esthetic area to avoid chances of tooth discoloration.

比较不同根管治疗材料(MTA Plus、Bio MTA+、Biodentine)导致的牙冠变色情况。
选取30颗因牙周问题而计划拔除的无龋坏的下颌和上颌完整人类前磨牙及磨牙,机械暴露牙髓后将其分为三组,即MTA Plus组、Biodentine组和Bio MTA+组。在进行牙髓切断术后,放置树脂改性玻璃离子粘固剂垫底,并用复合树脂充填牙齿。拔牙后,将牙齿保存在人工唾液中,最终在1天、7天、30天和60天后进行分光光度计分析。在每个时间间隔使用数码相机记录所有牙齿的图像,并记录和比较所有标本在各时间间隔的∆值。
大多数标本在放置MTA Plus、Biodentine和Bio MTA+后出现变色。统计分析显示,在观察期内,MTA Plus组、Bio MTA+组和Biodentine实验组之间存在显著差异。
在本研究条件下,与Bio MTA+和MTA Plus相比,Biodentine导致的变色明显较少。
三氧化矿物凝聚体材料比Biodentine在牙齿表面导致更多的变色。因此,在美学区域使用时,Biodentine应作为首选材料以避免牙齿变色。
