Mobile application as a learning tool for improving dental students' knowledge regarding dental trauma.

Introduction: Current evidence suggests an important knowledge gain of health sciences' students and professionals with mobile devices (m-learning). This study aimed to verify whether different strategies of teaching (traditional lecture classroom, m-learning and association of both methods) would present greater efficacy in knowledge improvement regarding dental trauma in primary dentition.

Materials And Methods: An action research study using a participatory approach was conducted with 36 undergraduate Brazilian dental students.

A new "silver-bullet" to treat caries in children--nano silver fluoride: a randomised clinical trial.

Background: Untreated dental caries in children remains a public health challenge in poor communities.

Objectives: This prospective controlled clinical trial investigated the effectiveness of a new anti-caries agent, Nano Silver Fluoride (NSF), applied once a year to arrest caries in children.
