THE primary purpose of the masticatory process is to apply forces to the nutritional substances which are taken into the mouth, thereby causing a reduction in their size. The mechanism for this action includes the medium of tooth structure which not only applies these forces directly to the food masses, but is itself subject to the effects of these forces. In general, the effects of forces appl...

objectives: the purpose of this study was to evaluate the resistance to fatigue failure of five different nickel-titanium rotary files in three different curved trajectories. materials and methods: a total of 150 neoniti a1, race 25.06, mtwo 25.06, twisted file 25.06 and protaper next x2 files with the tip size of 25 were tested (n=30 for each group). three groove types simulating curved canals...

Dental caries and periodontal diseases, the two arch criminals of oral cavity, are essentially caused by the micro-organisms present in dental plaque [1]. In India, nearly 60-65% of the child population is affected by dental caries and 10% has periodontitis [2,3]. Dental plaque plays an important role in the development of dental caries and periodontal disease, which results in both dysfunction...

OBJECTIVES In an area of esthetic dentistry such as posterior composites, in which new materials and techniques are being devolved continuously, it is important to confirm that dental students have a clear understanding of the basic principles of clinical application of this knowledge. Considering that the preparation of dental graduates in Spain may be of interest to competent dental authoriti...

UNLABELLED The restoration of posterior teeth with directly placed resin-bonded composite requires meticulous operative technique in order to ensure success. Case and material selection; cavity preparation; matrix selection; isolation; bonding; management of polymerization shrinkage; placement; finishing and curing of posterior composites--all present a series of challenges that dentists must m...

The preparation and use of moulds and casts from cavities and organs has already been applied in several medical disciplines. It is a current method in stomatology in order to obtain an exact reproduction of the oral cavity for preparing dental prostheses. Plastic casts obtained from the filling of vessels, ducts, and cavities are of great interest for the anatomical knowledge of organs (Van de...

INTRODUCTION The conventional method of teaching endodontics has some drawbacks. Due to the small size of the oral cavity, students cannot closely observe the clinical procedure. Use of new teaching modalities such as the intraoral camera may obviate this problem. This study assessed the effect of video-assisted clinical instruction in dentistry (VACID) on dental student's knowledge and perform...
