Bond strength and marginal adaptation of a novel root-end filling material
Tóm tắt
Apicoectomy with retrograde filling is considered as a tooth saver. Mineral trioxide aggregate (MTA) is mostly recommended as a root-end filling material as it is proved to have excellent sealing ability and hard tissue repair. Aside from these advantages, MTA has some disadvantages, such as weak handling properties, long setting time, and discoloration potential. Nanotechnology is now undergoing rapid development. Recently, experimental nano-white mineral trioxide aggregate (nano-WMTA) was prepared and introduced by NanoTech Egypt (Al Giza, Egypt) as a root-end filling material. The manufacturers claim that it has similar composition to white MTA, but with the reduction of its particle size to obtain a high specific powder surface area that may lead to a better and faster hydration process. It seems worthy to study the bond strength and marginal adaptation of the newly introduced nano root-end filling materials and compare it with the conventionally used MTA in root-end cavities. In push-out test, no statistically significant difference was found between nano-WMTA and MTA Angelus groups where p = 0.459. The nano-WMTA group recorded the highest mean value. For scanning electron microscope evaluation, there was a statistically significant difference between the nano-WMTA and MTA Angelus groups where p < 0.001. The MTA Angelus group recorded the highest mean value of gap distance. Nano-WMTA recorded a similar bond strength to MTA Angelus. The nano-WMTA showed significantly higher marginal adaptation to root-end cavity than MTA Angelus.
