Laboratory Properties and Clinical Performance of Three Different Fluoride Releasing Restorative Materials

Abstract

To date, there are various types of restorative materials in the market that are suitable for use as filling materials for primary teeth. Among these materials were the newly introduced flowable colored PAM-CR. Owing to its flowable nature and color, it was suggested that these materials would be more accepted by children and would favor the needs of operator in terms of better adaptation to cavity walls, less incorporation of air voids, ease of application and acceleration of the filling process. Accordingly, this study was formulated in an attempt to test the flowable colored fluoride releasing polyacid-modified composite resin (PAM-CR) material and compare it to the most commonly used fluoride releasing filling materials in pediatric dentistry such as; resin-modified glass ionomer cement (GIC), tooth-colored PAM-CR and flowable resin composite. This study was divided into two parts; an in-vitro study and an in-vivo study in order to try to correlate some laboratory properties with the clinical performance of the tested materials. In-vitro study
