evaluation of the shear bond strength and fluoride release of a new bioactive dental composite material.

Background: The aim of this study was (1) to determine and compare the shear bond strength (SBS) of a bioactive composite "Activa Bioactive Restorative" with and without bonding agent and a nanocomposite "Filtek Z350 XT/Z350" and (2) to measure and compare the amount of fluoride release from a bioactive composite "Activa Bioactive Restorative" and a glass ionomer "Equia forte".

Material And Methods: Forty two dentin surfaces from freshly extracted human molars were prepared for shear bond strength testing. The specimens were randomly divided into three equal groups.

The impact of a prospective 4-year longitudinal school intervention for improving oral health and oral health inequalities in primary schoolchildren in Flanders-Belgium.

Background: Oral diseases and socio-economic inequalities in children are a persisting problem.

Aim: To investigate the 4-year longitudinal impact of an oral health promotion programme on oral health, knowledge, and socio-economic inequalities in primary schoolchildren.

Design: The intervention was carried out between 2010 and 2014 within a random sample of Flemish primary schoolchildren (born in 2002).
