Evaluation of adaptation of ceramic inlays using optical coherence tomography and replica technique

Brazilian Oral Research, 2018
Optical coherence tomography (OCT) has generally been used as a nondestructive technique to evaluate integrities of composite restorations. We investigated marginal and internal adaptations of ceramic inlay restorations with OCT and compared them to ...

Marginal adaptation of zirconia CAD-CAM copings with two cervical finish lines [PDF]

Journal of Dental Materials and Techniques, 2023
Introduction: Marginal adaptation is important for the long-term success of restorations. The finish line design can influence the marginal integrity. This study aimed to evaluate the effect of radial shoulder and deep chamfer finish line designs on the ...

Adaptively weighted large-margin angle-based classifiers [PDF]

Journal of Multivariate Analysis, 2018
Large-margin classifiers are powerful techniques for classification problems. Although binary large-margin classifiers are heavily studied, multicategory problems are more complicated and challenging. A common approach is to construct k different decision functions for a k-class problem with a sum-to-zero constraint.

In vitro analysis of the marginal adaptation and discrepancy of stainless steel crowns

Acta Biomaterialia Odontologica Scandinavica, 2018
Aim: The purpose of the study was to assess the marginal adaptation and discrepancy of SSC’s. Differences in adaptation and discrepancy between the four surfaces (mesial, lingual, distal, and buccal) were evaluated.

Comparative evaluation of effects of bleaching on color stability and marginal adaptation of discolored direct and indirect composite laminate veneers under in vivo conditions

The Journal of Indian Prosthodontic Society, 2015
Statement of Problem: Change in color and loss of marginal adaptation of tooth colored restorative materials is not acceptable. Bleaching is commonly used for treating discolored teeth.

On sharp bounds for marginal densities of product measures

, 2016
We discuss optimal constants in a recent result of Rudelson and Vershynin on marginal densities. We show that if $f$ is a probability density on $\R^n$ of the form $f(x)=\prod_{i=1}^n f_i(x_i)$, where each $f_i$ is a density on $\R$, say bounded by one ...

Root dentin surface activation to improve bioceramic bonding: Ascanning electron microscopic study [PDF]

Journal of Dental Research, Dental Clinics, Dental Prospects, 2020
Background. Bioceramics need to interact chemically with dentin to exhibit adequate bioactivity.Proper bonding of bioceramics with dentin is of considerable importance.

Intraspecfic variation in cold-temperature metabolic phenotypes of Arabidopsis lyrata ssp petraea [PDF]

, 2009
Atmospheric temperature is a key factor in determining the distribution of a plant species. Alongside this, plant populations growing at the margin of their range may exhibit traits that indicate genetic differentiation and adaptation to their local ...

Adherence to Protocol Recommendations for Children With Wilms Tumour in Two Consecutive Studies in the United Kingdom and Ireland—Does Variation Matter?

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background and Aims Wilms tumour (WT) has excellent event‐free and overall survival (OS). However, small differences exist between countries participating in the same international study. This led us to examine variation in adherence to protocol recommendations as a potential contributing factor.
