introduction: multiple myeloma is a neoplasm of monoclonal plasmacells which may cause oral manifestations. we report a 50-year-old man with a mass burned out of a post extraction socket. he had recived an eight month period of chemotherapy and was supposed to be ready for hematopoetic stem cell transplantation. after clinical and histopathological examinations, the mass was diagnosed as a plas...

BACKGROUND Determination of acute toxicity, expressed as median lethal dose (LD50), is one of the most important steps in drug discovery pipeline. Because in vivo assays for oral acute toxicity in mammals are time-consuming and costly, there is thus an urgent need to develop in silico prediction models of oral acute toxicity. RESULTS In this study, based on a comprehensive data set containing...

background and aims. occlusal rims are used to determine the jaw relationships in the transverse and vertical dimensions and estimate the inter-occlusal distance in edentulous patients. it is important to find ways to determine the height and shape of the occlusal rims correctly. the aim of the present study was to determine the exact distance between the oral cavity floor and the incisal edges...

Background and Aim: Secondary caries are a common challenge for dentists. Many researchers have evaluated the accuracy of digital radiographic systems in the detection of secondary caries and have reported controversial results. Therefore, the aim of this in vivo study was to determine the diagnostic accuracy of digital radiography in the detection of secondary caries in anterior teeth. Mate...

The current study aimed to examine the effects of strategic planning, online planning, strategic planning and online planning combined (joint planning), and no planning on the complexity, accuracy, and fluency of oral productions in two simple and complex narrative tasks. Eighty advanced EFL learners performed one simple narrative task and a complex narrative task with 20 minutes in between. Th...

If emergent genomic and proteomic approaches to early oral cancer detection are to be successful, a means of reliably and comprehensively identifying high-risk tissue sampling sites constitutes an essential step in the oral cancer screening process. Recent studies have determined that in vivo Optical Coherence Tomography (OCT) is a quick and user-friendly tool for detecting and mapping oral les...
