| 摘要: | Abstract
Background/Purpose
Mineral trioxide aggregate (MTA) was widely used in endodontic therapy as bioceramic material. Although MTA has high biocompatibility, it may lead to tooth discoloration. The aim of this study was to investigate the discoloration of two different bioceramic materials and the effects of internal bleaching.
Methods
Thirty single-canal mandibular premolars were extracted and randomly assigned to three groups (n?=?10), white ProRoot? MTA, SavDen? MTA and a control group. Endodontic access opening, cleaning and shaping were performed, then the teeth were obturated using the two bioceramic materials. Tooth color was recorded at baseline, day 1, and 1, 2, 4, 6, 8, 12, 16, and 24 weeks after treatment. At the end of 24 weeks, sodium perborate was used to perform internal bleaching. Tooth color was recorded at 1, 2, and 6 weeks subsequently. Teeth were measured using a DeguDent? spectrophotometer, and data were transformed into Commission Internationale de l'Eclairage (CIE) L?a?b? system.
Results
Teeth treated with white ProRoot? MTA showed significant color change and decrease in L? value. Internal bleaching leaded to decrease of the ΔE? value for all three groups and?increase in the L? value. There was no difference in tooth discoloration between SavDen? MTA and the control group after obturation and internal bleaching.
Conclusion
In terms of visual perception, white ProRoot? MTA tends to cause black and blue discoloration. SavDen? MTA, formulated with calcium lactate gluconate, could be used to reduce tooth discoloration in endodontic treatment. |
