Dental amalgam is widely used as a restorative material even though it is not esthetic and there has been extensive anti-amalgam rhetoric. Although other materials have improved greatly, amalgam has the proven safety record and best cost-to-benefit ratio. Clinical evidence indicates that, in the posterior permanent dentition--where esthetics is not a primary concern--the small, minimally prepar...

Multiple failures of transmission lines caused by climatic/atmospheric impact plague many electric power systems. Direct damage from such is quite huge, yet it marginal compared with the social reduction in supply electricity. As not economical to construct weatherproof lines, preventive actions should be employed most effective restoration, or reduce restoration time. A working group CIGRÉ (WG...

A bstract Restoration of the electroweak symmetry at temperatures around Higgs mass is linked to tight phenomenological constraints on many baryogenesis scenarios. potential remedy can be found in mechanisms non-restoration (SNR), which breaking extended higher due new states with couplings Standard Model. Here we show that, presence a second doublet, SNR realized only handful fermions identifi...

Aesthetic requirement of severely mutilated primary anterior teeth in the case of early childhood caries has been a challenge to pediatric dentist. Among restorative treatment options, prefabricated crown and biological and resin composite restoration either by means of direct or indirect technique are mentioned in the literature. This paper presents the clinical sequence of rehabilitation of m...

In this paper, the problem of how to better estimate spatially adaptive intensity bounds for image restoration is addressed. When the intensity bounds are estimated from a degraded image, blurring leads to underestimation of the bounds in the edge and texture regions. Therefore, an iterative implementation of the restoration algorithm has been proposed in which the intensity bounds are re-estim...

Minimally invasive restorative techniques can be applied with direct resin composites. However, the preparation for an indirect restoration tends to lead to over-treatment of the tooth structures. A resin-coating technique has been proposed in which both a hybrid layer and a tight sealing film are produced on the dentin surface with a dentin adhesive system and a low viscosity micro-filled resi...

OBJECTIVE This article presents a case report of restoration of anterior teeth using an indirect technique with composite veneers in order to restore the dental anatomy and to provide aesthetic and function of anterior teeth. MATERIALS AND METHODS A treatment of upper anterior teeth with indirect micro-hybrid composite restoration was proposed to a 40-year-old woman with old discolored and fr...

One of the most common methods dental treatment in a minimally invasive concept is direct restoration carious damaged teeth or with trauma. In this article represents clinical case old unsatisfactory restorations replacement 36, 37 followed by hard tissue class II defects using composite taking into account aesthetic and biomechanical aspects.

Most conventional image processors consider little the influence of human vision psychology. Weber’s Law in psychology and psychophysics claims that human’s perception and response to the intensity fluctuation of visual signals are weighted by the background stimulus , instead of being plainly uniform. This paper attempts to integrate this well known perceptual law into the classical total vari...

Aligning a displaced maxillary canine into the dental arch is one of the most complicated problems in orthodontics. In cases of extremely high displacement, the tooth is frequently removed surgically. Because of the upper canines' significance to dental esthetics and functional occlusion, such a decision is a very serious one. The purpose of this report is to illustrate an interdisciplinary app...
