Apicoectomy by retrograde guttapercha filling.

In-vitro Sealing Ability of Calcium Enriched Mixture Cement Versus Amalgam as Retrograde Filling Materials

Introduction: Sealing ability of a retrograde filling material is an important factor for a successful endodontic apicoectomy. The purpose of this in-vitro study was to compare the sealing ability of calcium enriched mixture (CEM) cement versus amalgam as root-end filling materials. Methods: A total of 36 canals of extracted maxillary central incisors were instrumented and obturated using later...

Secure FPGA Design by Filling Unused Spaces

Nowadays there are different kinds of attacks on Field Programmable Gate Array (FPGA). As FPGAs are used in many different applications, its security becomes an important concern, especially in Internet of Things (IoT) applications. Hardware Trojan Horse (HTH) insertion is one of the major security threats that can be implemented in unused space of the FPGA. This unused space is unavoidable to ...
