This paper presents a method for implementing fully automatic timing on a personal electronic device. An initial firstpass is done through all of the video frames, finding the subtracted image between the video frames and the initial image of finish line to determine an estimated frame where the object first crosses the finish line. After this frame has been found, the SIFT and RANSAC algorithm...

The success of any fixed prosthesis depends on the accuracy of impressions. Finish line exposure has to be adequate during impression making. The goal of gingival retraction is to atraumatically displace gingival tissues to allow access for impression material to record the finish line and provide sufficient thickness of gingival sulcus so that the impression does not tear off during removal. N...

Few studies have examined the contribution of individual psychological factors to long-term indicators academic success.This study examines influence personality and difference in relation retention. In this study, 290 Canadian undergraduate students completed measures personality, resiliency, perfectionism, trait Emotional Intelligence first semester their year, enrolment status was collected ...

STATEMENT OF THE PROBLEM Although all-ceramic restorations are broadly used, there is a lack of information concerning how their fit is affected by fabrication procedure and marginal configuration. PURPOSE The purpose of this study was to evaluate the marginal fit of zirconia CAD/CAM ceramic crowns before and after porcelain firing. The influence of finish line configuration on the marginal f...

The aim of this study was to evaluate the vertical marginal gap of sintered gold copings and metal-ceramic crowns with different finish line preparations: a beveled round shoulder (BRS) and a beveled long chamfer (BLC), testing the null hypotheses that there are no differences in marginal gap regardless of finish line and phase of restoration (coping or crown). Stainless steel master models wer...

OBJECTIVES This in-vitro study investigated the marginal fit of two all-ceramic copings with 2 finish line designs. METHODS Forty machined stainless steel molar die models with two different margin designs (chamfer and rounded shoulder) were prepared. A total of 40 standardized copings were fabricated and divided into 4 groups (n=10 for each finish line-coping material). Coping materials test...

The primary purposes of this investigation were to evaluate sophomore dental student performance in the production of a chamfer finish line using two diamond bur types-a round-ended bur and a torpedo-shaped bur-and to gain student feedback about their preferences for bur type. Fifty students took part in the study, each of whom prepared the buccal surfaces of two mandibular molar typodont teeth...
