Introduction: Extension of denture borders beyond the border line can lead to abnormal movement of the denture and therefore possible loss of retention. Soreness or sore spots that appear in the day(s) after insertion may also result from the overextended borders. Objectives: This article presents a simple technique to evaluate denture border extensions using silicone impression material. Mater...

The purpose of this study was to determine the different reasons for root canal failure in the department of dentistry at Pakistan Institute of Medical Sciences. It was a cross sectional study which was based on collection and interpretation of data. Seventy patients of both genders were selected from dental out patient department of PIMS. All patients selected, presented with post endodontic c...

This paper describes an unusual clinical report of local argyrosis due to corrosion of endodontic silver point within the buccal root canal of an upper left second premolar. Localized oral pigmentation of the periapical mucosa was observed during routine dental check-up. The X-ray examination revealed endodonticaly treated tooth with overextended silver point and periapical resorption. Removal ...

This research explored overextension in the early vocabularies of six children, followed in a language diary study from I; 0 to I; 8. , Results indicated that only one-third of the first 75 words acquired by each child were ever overextended. A small set of high-frequency, early acquired words accounted for a disproportionate number of overextensions. Overextensions were classified into three t...

In this brief, the margin of stability of two-dimensional (2D) discrete systems is considered. A new method to compute the stability margin of 2-D continuous systems is provided. Illustrative examples are also included.

Typical bounds on generalization of Support Vector Machines are based on the minimum distance between training examples and the separating hyperplane. There has been some debate as to whether a more robust function of the margin distribution could provide generalization bounds. Freund and Schapire (1998) have shown how a diierent function of the margin distribution can be used to bound the numb...

Certain members of society are disproportionately affected by the COVID-19 crisis and added strain being placed on already overextended health care systems. In this article, we focus refugee newcomers. We outline vulnerabilities newcomers face in context COVID-19, including barriers to accessing services, disproportionate rates mental concerns, financial constraints, racism, higher likelihoods ...

This brief presents a new contribution in the problem of computing the stability margin of two-dimensional (2-D) discrete systems. The method, using the “resultant technique” instead of a typical minimization procedure , is actually an improvement of the method of .
