A COMPREHENSIVE REVIEW OF VARIOUS LASER-BASED SYSTEMS USED IN EARLY DETECTION OF DENTAL CARIES Fawad Javed DDS, DMD, PhD, Research Associate Division of General Dentistry, Eastman Institute for Oral Health University of Rochester, NY, USA CV Dr. Fawad Javed completed his doctoral education and post-doctoral training at the Department of Dental Medicine, Karolinska Institutet, Stockholm, Sweden. Dr. Javed has published over 90 articles in ISI-indexed medical and dental journals. Presently, Dr. Javed is a postdoctoral fellow and Research Associate at the Division of General Dentistry, Eastman Institute for Oral Health, University of Rochester, NY, USA. Dr. Javed’s research interests include oral oncology research, the connection between oral inflammatory disorders and systemic conditions particularly diabetes mellitus, the impact of smoking and use of smokeless tobacco on oral health, the cytokine profile in serum and oral fluids in patients with and without systemic conditions, implant dentistry, bone regeneration research and saliva research. Dr. Javed is a member of the Editorial board and also a member of peer-review panels of various indexed medical and dental journals. Questions Dental caries are caused by the action of cariogenic bacteria on: q a. q b. q c. q d. Soluble proteins; Fermentable carbohydrates; Lactose; Teeth. Traditionally, caries are diagnosed by: q a. q b. q c. q d. X-rays; Computed tomography; Lasers; Visual examination. One factor that makes light-emitting-diode and light fluorescence beneficial in the early detection of dental caries is: q a. q b. q c. q d. Both are inexpensive; Both produce good reproducibility; Both are technique sensitive; Both are surgical lasers. The DIAGNOdent system uses______ for caries detection: q a. q b. q c. q d. Digital imaging fiber-optic transillumination; Digital imaging xrays; Ultrasonic waves; None of the above. 113
