The reverse engineering process for VLSI chips is a complex operation that can cost from $10,000 for the simplest chips to hundreds of thousands of dollars for complex chips. In this study, we present an overview of the process of reverse engineering VLSI chips. The study outlines the steps involved in the process of reverse engineering chips as well as the different techniques used to extract ...

The root canal system is colonised with microorganisms in cases of apical periodontitis. Currently, it is impossible to totally eliminate these microbes purely with mechanical instrumentation. Therefore, irrigants are required to eradicate intraradicular infection. In this article, the different actions and interactions of the most commonly used irrigants are discussed and a clinical protocol s...

Purpose: To evaluate the efficacy of immediate loading versus early loading at 6 weeks of bar-retained mandibular overdentures supported by two implants placed with a flapless technique. Materials and methods: Sixty patients were randomised: 30 to the immediately loaded group and 30 to the early loaded group. To be immediately loaded, implants had to be inserted with a minimum torque > 48 Ncm. ...

This report describes a rare palato-radicular groove in a maxillary lateral incisor with an accessory root and an atypical root canal. Failure to identify the presence of the palatal groove allowed infection to persist, which led to palatal swelling and labial fistula. During endodontic retreatment of the infected root canal, an accessory root with a second root canal was detected. Owing to the...

61 The Chinese Journal of Dental Research implants (MDIs) may offer an additional option to fix the prosthesis, even though they are not yet widely used and tested. Facial defects including nasal mucous tissues show high sensitivity to minor irritations. Irritation of this tissue can occur when in intimate contact with the prosthetic material. The purpose of this case report is to demonstrate t...

The impact factor mania, also called impactitis, continues to play an improper role in the choices made by most investigators as to which journals to submit their research articles in the biomedical fields, and still worse, in the decisions taken by governing bodies and research grant allocators, as highlighted in a recent mBio editorial (1). Other factors, however, are threatening the scientif...
