Outcome of Calcium Silicate Sealer‐Based Obturation in Root Canal Retreatment: A CBCT‐Based Prospective Cohort Study

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Background Calcium silicate sealers (CSS) have become the dominant approach to root canal obturation in many specialist practices, yet evidence on their performance in nonsurgical retreatment is sparse and CBCT‐based assessment remains uncommon.

Rethinking Reciprocity

open access: yesAnnual Review of Economics, 2014
Reciprocal behavioral has been found to play a significant role in many economic domains, including labor supply, tax compliance, voting behavior, and fund-raising. What explains individuals’ tendency to respond to the kindness of others? Existing theories posit internal preferences for the welfare of others, inequality aversion, or utility from ...

Predictive evolutionary genomics: principles, validation, and practice

open access: yesNew Phytologist, EarlyView.
Summary Climate change and habitat loss are driving rapid evolutionary responses in populations world‐wide, which creates an urgent need for evolutionary forecasting in conservation and agriculture. Such forecasting can be categorized into three time scales: trait‐based models that use multivariate quantitative genetic equations to project correlated ...

The (Un)deserving Parent: Exploring Parental Argumentation and Sole‐Custody Decisions in Swedish Courts

open access: yesSocial Policy &Administration, EarlyView.
ABSTRACT Across the Western world, joint legal and physical custody is increasingly becoming the default post‐separation arrangement. While family policy and law encourage such arrangements, they may not suit every situation. In child‐custody court disputes, courts must consider whether sole legal custody is the best alternative for the child in each ...

Comparative Assessment of Canal Transportation and Centering Ability of Reciproc and One Shape File Systems Using CBCT-An In Vitro Study [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2017
Introduction: Root canal preparation leads to deviation of the canal anatomy causing canal transportation which affects the success of the treatment. Cone Beam Computed Tomography (CBCT) is a non invasive imaging technique to analyse the shape of the
