STATEMENT OF PROBLEM The penetration of oral fluids and bacteria at the interface between the preparation walls and amalgam restorations, known as marginal microleakage, continues to be a problem in restorative dentistry. Microleakage may result in secondary caries and the irritation of the pulp. PURPOSE This study evaluated the effect of amalgam type,(More)
The local Young modulus of dry dentin viewed as a hierarchical composite was measured by nano-indentation using two types of experiments, both in a continuous stiffness measurement mode. First, tests were performed radially along straight lines running across highly mineralized peritubular dentin sections and through less mineralized intertubular dentin(More)
This article describes the principles of laser operation and the clinical application of laser technology in the different fields of dentistry. It discusses the use of the Er:YAG laser in restorative dentistry, pediatric dentistry, and periodontics, as well as the introduction of a new side-firing spiral tip for efficient cleaning of the root canal system(More)
Many over-the-counter microbicidal contraceptive methods reduce the risk of acquiring sexually transmitted diseases. This pilot project compared the use of female controlled barrier methods in an extremely high-risk population of low-income drug abusing women following an intervention designed to promote HIV risk reduction and barrier use. An HIV(More)
STATEMENT OF PROBLEM Forced eruption is a prosthodontic procedure that enables the treatment of otherwise problematic restorative conditions. During the vertical orthodontic movement, the root may be moved laterally, affecting the position of a tooth in the arch. PURPOSE This study quantified the degree of lateral movement possible during the eruptive(More)
Lingual forced eruption is a treatment modality that minimizes esthetic impairment during orthodontic treatment. Use of this technique can enhance the acceptance of orthodontic treatment by adult patients and minimize unnecessary compromises in the treatment planning of submerged roots. In this clinical report, a treatment modality for forced eruption(More)
OBJECTIVES We present a novel way to create high-resolution three-dimensional images of tooth dentin by harmonic generation scanning laser microscopy. METHODS The images were taken using a pulsed infrared laser. Three-dimensional reconstruction enables the visualization of individual tubules and the collagen fibrils mesh around them with an optical(More)
OBJECTIVES The small volume of human dentin available for sample preparation and the local variations in its microstructure present a real challenge in the determination of their mechanical properties. The main purpose of the present study was to develop a new procedure for the preparation and mechanical testing of small-scale specimens of biomaterials such(More)
