BACKGROUND One method used to disinfect a dental cast is immersion in a disinfecting solution. Repeated immersion of a cast in disinfectant may affect its physical properties. PURPOSE The purpose of this study was to evaluate the changes in dimensional accuracy and hardness of the dental casts as a result of repeated disinfection in 0.525% sodium(More)
Dental Implants have become the standard care of rehabilitation of missing teeth. This article intends to review the success criteria for implants from 1979 till date. Earlier days implant success was evaluated by immobility and peri-implant radiolucency. But currently, the width of the attached gingiva, co-existing medical conditions, smoking, and width of(More)
OBJECTIVE This study was performed to assess the resin tag length penetration in enamel surface after bonding of brackets to identify which system was most efficient. METHODOLOGY Our study was based on a more robust confocal microscopy for visualizing the resin tags in enamel. Totally, 100 extracted human first and second premolars have been selected for(More)
Two-way relaying (TWR) reduces the spectral-efficiency loss caused in conventional half-duplex relaying. TWR is possible when two nodes exchange data simultaneously through a relay. In cellular systems, data exchange between base station (BS) and users is usually not simultaneous e.g., a user (TUE) has uplink data to transmit during multiple access (MAC)(More)
— This paper proposes a novel energy harvesting system model based on combined electromechanical and electromagnetic transduction technique. A cantilever substrate (beam) with piezoelectric (PZT) patch and a mass at the tip is considered for electromechanical transductions. A magnet is hanged through a spring at the tip of the composite beam over a printed(More)
Guidelines to prevent cross contamination with infectious agents have been instituted for dental clinical and laboratory procedures. However, compliance by dental offices and clinics in disinfecting impression material has not been universal. Techniques for disinfecting impression materials are spraying or immersing impression materials. These techniques(More)
