Human and animal skeletal remains can provide information about the food chain of inhabitant’s nutrition of archaeologicalsites. The food chain which at it minerals and organic materials transferred from soil to the plants, from plants to theanimals, and from herbivores animals to the carnivores, is the benchmark system in ancient diet. Although Chemicalinteractions between soils, animal and hu...
Background: Avian rotaviruses are one of the important agents of enteritis in birds and have a worldwide distribution. These viruses have an important role in runting and stunting syndrome in chickens. Objectives: The aim of this study was detection and molecular characterization of avian rotaviruses in broiler farms in Guilan province. Methods: In this study, 100 samples were collected on diff...
Introduction: Simultaneous etching of enamel and dentin using the novel generation of adhesive systems with contracted operational steps, has shown a good clinical efficacy. The aim of this study was to evaluate the microleakage of composite restorations using the V and VII generations of adhesive systems on primary teeth. Methods: This study was performed on 45 human intact extracted primar...
The purpose of this study is to assess the microleakage in CL V Amalgam restoration lined with and without varnishes and dentine bonding agents. In this study, two varishes (Kimia and Copalite) and two dentin bonding agents (Syntac and Excite) were used. 70 fresh human premolars were selected for this study. These samples were randomly divided to five groups (four group of 15 teeth and one grou...
Background and Aims: The main cause of erosion is acid exposure . Side effects of erosion necessitate therapeutic agents’ uses. The aim of this study was to investigate the effects of nano- hydroxy apatite in tooth remineralization following exposure to soft beer. Materials and Methods: This in vitro experimental study was conducted on 18 human impacted third molars that had been surgically...
This study aimed to determine the validity of the digital photocolorimetric (PCM) method in matching the color of human teeth. First, two Vitapan Classical shade guides, each containing 16 shade guide teeth, were visually shade matched, and digital photographs of each three pair of shade guide teeth were taken in a color matching booth. Secondly, visual shade matching of the upper central incis...
