Nanodevices based circuit design will be based on the acceptance that a high percentage of devices in the design will be defective. In this work, we investigate a defect tolerant technique that adds redundancy at the transistor level and provides built-in immunity to permanent defects (stuck-open, stuck-short and bridges). The proposed technique is based on(More)
AIM To compare pregnant and non-pregnant females for vitamin D level and periodontal status and to determine if there is any association between the periodontal health and hypovitaminosis D in pregnant women. MATERIALS AND METHODS A cross-sectional study was conducted in Jhelum, Pakistan. Participants were pregnant females at ~ 12 weeks of gestation (n =(More)
AIM To compare the difference in microleakage values using conventional and new low-shrink Silorane composites using the dye penetration method. BACKGROUND With improvement in adhesive technology, problems associated with composites have been largely overcome. However, microleakage due to polymerization shrinkage still remains a challenge. New(More)
INTRODUCTION The mesiobuccal root of the maxillary first molar has generated more research and clinical investigation than any root. An inability to detect and treat a second mesiobuccal (MB2) canal is a reason for endodontic failure in maxillary first molars. Modifications in the endodontic access and detection techniques, along with advancements in(More)
Invasive cervical resorption is a condition that affects the root surface area below the epithelial attachment. Multiple treatment modalities are advocated, involving exposure of the invasive defect, removal of the granulation tissue and sealing with various restorative materials. This report demonstrates conservative treatment of a patient presenting with(More)
OBJECTIVE To determine the accuracy of extra oral periapical radiography in obtaining root length by comparing it with the radiographs obtained from standard intraoral approach and extended distance intraoral approach. MATERIALS AND METHODS It was an in vitro, comparative study conducted at the dental clinics of Aga Khan University Hospital. ERC exemption(More)
Eelgrass (Zostera marina L.) is an important organism in coastal marine waters and is highly likely to encounter exposure to multiple stressors, both anthropogenic contaminants and natural stressors. Here, we exposed eelgrass to a range of Cu concentrations and salinities, and also varied exposure route between sediment and water. Measured endpoints were Cu(More)
The mesiobuccal root of the maxillary first molar has generated more research and clinical investigation than any other root. An inability to detect and treat a second mesiobuccal canal (MB2) is a reason for end-odontic failure in maxillary first molars (1). Modifications in endodontic access and detection techniques, along with advancements in illumination(More)
