Findings: MagicFil is a new poly acid-modified resin-based composite (compomer.) The material polymerizes both by visible light activation and chemical resin curing. While other compomers undergo resin polymerization only by light exposure, the 2-component colored compomer is blended while being injected through the tip also activating chemical polymerization. The other unique side to this compomer is that the material is manufactured in four bright colors with “glitter” inclusions. The colors are blue, purple, yellow and universal. This material is specifically designed for restorations on primary teeth. The physical properties are that of any poly acid-modified resin-based composite and can be used in the same fashion ie: Class I, Class II and Class V restorations. The application of this material is also the same as any other compomer. The author recommends treating teeth that are expected to exfoliate within 3-5 years. They also state that the children ages 7-11 are the biggest enthusiasts for this new material.

Method: A single case and it’s preparation was discussed 1) Same cavity preparation as a composite, no need to include sharp angels or grooves. 2) GI base was used due to deep preparation 3) place matrix band and wedge 4) rough enamel surfaces with high speed diamond bur 5) L-pop or any self etching material can be used along with a bonding agent 6) small increment of material (PURPLE shade) 1-1.5 mm thick injected into preparation and light cured for 30 seconds 7) second layer applied and cured for 40 seconds 8) trim excess composite with high speed 9) etch a second time, rinse, add sealant to grooves and cure 10) check occlusion

Key Points: Great material for pediatric practice. Physical properties of material are that of any poly acid modified resin-based composite.

Assessment of the Article: Since one of the authors was head of our Pedo department at Temple I had already heard of the material. It seems like it would have use in a Pedo practice and would offer our pediatric patients another choice in their dental treatment. Also, who doesn’t like Glitter ....right Jessi?
