Fourteen root perforations were performed for microscopic evaluation of the repair of interradicular tissue in dogs' teeth. These perforations were accomplished at low-speed with a STP 58 bur at the cervical third of the mesial root toward the furcation under irrigation with saline solution, followed by immediate sealing with ProRoot MTA, MTA-Angelus and white Portland cement. The dogs were kil...

introduction: adequate seal of iatrogenically perforated area within the root canal system can improve the long term treatment prognosis. this in vitro study evaluated the sealing ability of mineral trioxide aggregate (mta), calcium-enriched mixture (cem) cement and biodentine in repair of furcation perforation in primary molars. methods and materials: a total of 61 freshly extracted primary ma...

In this paper, a system for P2P networks with discrete time delay based on game theory presented. This system is proposed to describe evolution procedure of the credibility of various members in the P2P network. Through analyzing the stability of the system model based on the Lyapunov stability theory, the conditions for Hopf bi furcation and stability are obtained. Finally, some numerical exam...

Tissue engineering in the orofacial region with bioactive components by activation of immune complexes or other proteins is current focus biomaterials research. Consequently, natural ground materials and tissue are being created. Bioactive glass one most promising has properties making it suited for a range different clinical dental applications, including regeneration hard tissues craniofacial...
