Terezhalmy, DDS, MA This article provides a comprehensive review of squamous cell carcinoma of the oral tissues and familiarizes healthcare professionals with the availability and application of diagnostic modalities beyond conventional visual inspection and palpation of oral soft tissues.
	Effect of Placement Techniques on the Marginal Adaptation of Class V Composite Restorations Luis Guilherme Sensi, DDS, MS, PhD; Fabiano Carlos Marson, DDS, MS, PhD; Luiz Narciso Baratieri, DDS, MS, PhD; Sylvio Monteiro Junior, DDS, MS, PhD This study evaluates the effect of different techniques of composite increment placement on the marginal adaptation of Class V restorations.
	The Significance of Marginal Gap and Overextension Measurement in the Evaluation of the Fit of Complete Crowns Arne F. Boeckler, DDS; Anke Stadler, DDS; Jürgen M. Setz, DDS, PhD An important criterion for the success of a crown is marginal fit. However, in the patient’s mouth fit can only be evaluated by subjective methods.  This study describes the correlation between objective marginal fit and its subjective evaluation by dentists and dental technicians.
	The Color Differences Between Different Thicknesses of Resin Veneered Over Amalgam Yousra Hussain Al-Jazairy, BDS, Msc; Ahmed A. El-Hejazi, BDS, MSc, PhD Composites and compomers are popular in dental practice.  However, little is known about their esthetic appearance as veneering restorative materials over amalgam restorations.  This in vitro study evaluates the color differences of composite and compomer restorative materials, placed in thicknesses of 1 mm and 2 mm over amalgam.
	Alteration of Cyclic Nucleotides Levels and Oxidative Stress in Saliva of Human Subjects with Periodontitis Fereshteh Mashayekhi, PharmD; Farzaneh Agha-hosseini, DDS; Ali Rezaie, MD; Mohammad J. Zamani, PharmD; Reza Khorasani, BSc; Mohammad Abdollahi, PharmD, PhD The presence of oxidative stress and lower levels of salivary cGMP and cAMP in periodontitis are in association with disease severity.  Oxidative stress is a major contributor to the pathogenesis of inflammatory diseases.  This study was conducted to evaluate salivary oxidative stress along with the cGMP and cAMP secondary messenger levels in periodontitis subjects.
	Load-to-fracture Value of Different All-ceramic Crown Systems Mark David Snyder, DDS; Kyle Douglas Hogg, DDS This study investigates the potential difference in the load-to-fracture values of several all-ceramic crown systems.
	Perceived Sources of Stress within a Dental Educational Environment Wael Mousa Al-Omari, PhD The aim of this study was to identify the perceived sources of stress among dental students, dental hygiene students, and dental technology students enrolled at the Jordan University of Science and Technology (JUST).
	Oral Health Status in a Population of Nigerian Diabetics Eyitope Ogunbodede, DDPH, RCS; Olawunmi Fatusi, FMCDS; Anthony Akintomide, FWACP; Kikelomo Kolawole, BChD; Adesuyi Ajayi, FWACP While the oral manifestations of diabetes mellitus have been well documented, the effect of glycemic control on the oral tissues has not.  This article reports the oral health status of metabolically controlled adult diabetic patients assessed over six months compared with non-diabetics acting as controls.
	Assessment of DMFT and Enamel Hypoplasia Among Junior High School Children in Iran A. R. Daneshkazemi, DDS, MS; A. Davari, DDS, MS This study examines the prevalence and distribution of decayed, missing, and filled teeth (DMFT) and enamel hypoplasia in 12-year old students in junior high school in Iran.
	Physical Properties of Four Acrylic Denture Base Resins Thomas R. Meng, Jr, DDS; Mark A. Latta, DMD, MS Resistance to impact fracture and high flexural strength are desirable properties of denture base acrylics.  The purpose of this laboratory study was to determine the Izod impact strength, the flexural strength, the flexural modulus, and the yield distance for four premium denture resins.
	Fetal Alcohol Syndrome:  Anthropometric and Oral Health Status Sudeshni Naidoo, BDS, LDS.RCS, MDPH, DDPH.RCS, MChD, PhD; Usuf Chikte, BChD, MSc, DHSM, MDent; Ria Laubscher, BComm; Carl Lombard, PhD The purpose of this study was to analyze the anthropometric measures and oral health status of children with fetal alcohol syndrome (FAS) and compare them to matched controls.
	Effects of Nd:  YAG Laser Irradiation on the Adaptation of Composite Resins to Root Dentin Güliz Görgül, BDS, PhD; Bagdagül H. Kivanç, BDS; Murat Maden, DDS, PhD; Özgür Ilke Atasoy Ulusoy, BDS; A. Cemal Tinaz, BDS, PhD One of the most important goals in the restoration of endodontically treated teeth with a composite resin post system is to achieve good adaptation of the composite material to dentin walls to prevent microleakage apically and coronally.  In post core systems, to avoid microleakage between the dentin wall and resin material, laser irradiation may seem to be an alternative therapy for increasing adaptation quality.  This study investigated the adaptation of a packable composite resin to lased root canal dentin when it was used as post material.
	The Prevalence of Dental Caries among International Students at U.S. Universities Karl F. Woodmansey, DDS This paper discusses the known prevalence and causative factors of dental disease among international students, reported global variations in oral health, and barriers to receiving care faced by international students while in the U.S.
	Failures Related to Crowns and Fixed Partial Dentures Fabricated in a Nigerian Dental School Adeleke Oke Oginni, BChD, FMCDS This article documents the failure rate and length of service of crowns and fixed partial dentures (FPDs) fabricated in a Nigerian dental school.
