The recent advances in molecular biology have revolutionized all aspects of dentistry. DNA, the language of life yields information beyond our imagination, both in health or disease. DNA fingerprinting is a tool used to unravel all the mysteries associated with the oral cavity and its manifestations during diseased conditions. It is being increasingly used in analyzing various scenarios related...
In paleo-anthropology the fragility of fossil pieces (teeth and supporting bones) reduces their possible manipulation when studying the interarch relations. Two original impression methods of the jaw pieces are proposed, both adapted from those currently practiced in odontology. The plaster replicas of the dental occlusal parts are prepared according to the manufacturing procedures used in pros...
Laser technologies are widely used in various areas of contemporary practice not only in engineering but also in medicine. Owing to them, more accurate and precise results are achieved in making objects of unique shape and size for various purposes. In recent years, these technologies have entered rapidly into dental prosthetics. Several processes are mainly used: laser cutting, laser welding, ...
Time Compression Technologies (TCT) are strongly widening their application fields, particularly in not traditional sectors, such as archaeology, jewellery, architecture and so on. The biomedical domain, especially orthodontics, is one of the most interesting. The design and positioning processes of corrective dental appliances consist of phases which can strongly benefit from Reverse Engineeri...

BACKGROUND/AIMS Currently available techniques for fluoride analysis are not standardized. Therefore, this study was designed to develop standardized methods for analyzing fluoride in biological and nonbiological samples used for dental research. METHODS A group of nine laboratories analyzed a set of standardized samples for fluoride concentration using their own methods. The group then revie...
Maxillofacial deformities that result from trauma, developmental abnormalities, destructive cancer surgeries, surgically operated mucormycosis can be difficult for a person to deal with as it affects the esthetics and functions further degrades their quality of life. Hence, maxillofacial prosthesis not only corrects deformity but also boost self-confidence so patient live his/ her life fullest....
OBJECTIVES The aim of this survey was to determine how a sample of dentists working in general dental practice in the UK sought to restore the mouths of patients who had shortened dental arches (SDAs). STUDY DESIGN A survey was conducted over a period of six months on four commercial dental laboratories. Cases of SDAs comprising the anterior teeth and 2 to 4 premolars were examined; dental pr...
CONTEXT In dental practical classes, the acoustic environment is characterized by high noise levels in relation to other teaching areas, due to the exaggerated noise produced by some of these devices and use of dental equipment by many users at the same time. AIMS To measure, analyze and compare noise levels of equipments among dental learning areas under different working conditions and also...
