Undergraduate dental students' perceptions of dental pain in children - A grounded theory study.

Introduction: There is an underuse of pain management strategies in dental care for children, possibly owing to perceived stress and discomfort when treating children, which has also been reported by dental students. The aim of this study was to explore how undergraduate dental students experience and understand pain related to dental treatment in children.

Materials And Methods: Interviews were held with 21 Swedish dental students, from 3 dental schools, all in their final 2 years of education.

Effect of production method on surface roughness, marginal and internal fit, and retention of cobalt-chromium single crowns.

Statement Of Problem: New production methods have been developed for metal-ceramic restorations. Different production methods may show different surface roughness and fit, which may affect retention and long-term success.

Purpose: The purpose of this in vitro study was to examine 3 different production methods with regard to surface roughness, marginal and internal fit, and retention of cobalt-chromium alloy single-crown copings.
