Traditionally, dental-shade-guide standards are designated in terms of Munsell hue (H), value (V), and chroma (C). However, delta E color differences proposed as ADA tolerances for shade guides are in the CIE L*a*b* system. The purpose of this study was to evaluate a new color-difference equation, delta EM = C delta H/5 + 7 delta V + 4 delta C for estimation of small color differences by Munsel...

Paul Erdős liked fruit salad. I mixed this one for him from ingredients obtained while working on some of his problems. He was pleased by it and carried it to several places to offer to others as well. It is very sad that I have to add to the manuscript: dedicated to his memory. 1. Nearly bipartite graphs. Szentendre, 1994. Although we are in the shade, the summer afternoon is very hot, the wat...

We examine a stylized version of EPA auctions when agents know the list of values of sellers and buyers. Sellers and buyers behave strategically. We show that there are two types of equilibria: inefficient equilibria where no goods are traded and efficient equilibria where alI exchange occurs at a uniform price. We also provide examples of the EPA auction game under incomplete information when ...

Color is one of the integral parts of esthetic dentistry that affects the satisfaction of patients with their restorations. Because of the complexity of the optical properties of the natural teeth, color reproduction is one of the most challenging issues which the clinicians encounter with [1] Ceramic restorations are applicable in situations with high esthetic demands. They can mimic the appea...

INTRODUCTION Smile is one of the most important interactive communication skills of a person. A smile is the key factor for an aesthetic appearance. Hence aesthetics is one of the motivating factor for the patients to seek dental care. Correction of unaesthetic appearance gives a positive effect to the self esteem of the patient. AIM The aim of this study was to compare the difference in the ...

The clinical study aimed to evaluate the repeatability of Intraoral Scanner (IOS) in terms dental shade selection comparison visual method and find if difference between these two methods is clinically acceptable. As well as assess impact tooth position on IOS selection. Two experienced raters have selected shades 38 right maxillary incisors, canines, molars patients different days under same c...

Last minute bidding on internet auctions is not compatible with standard private value (PV) settings. However, it can be rationalized by adding (at least) another identical auction. In the sequential ebay auction model, it can be proved that the last minute bidding equilibrium, in which bidders only bid at the last minute, is the unique symmetric perfect Bayesian equilibrium in (weakly) undomin...
