Clinical Trial NuSmile Crowns

Stainless steel crowns have been the most common treatment for large cavities in baby teeth until recently. These crowns are silver in color, and aesthetically are not a good option for restoring front teeth. Several tooth colored options have been developed to meet the growing demand for more aesthetics on front teeth. With the variety of new options for restoring anterior primary teeth, the investigators would like to evaluate the long-term success of three tooth-colored restoration options: NuSmile Signature crowns, NuSmile ZR crowns, and composite crowns. The investigators are interested in looking at the outcomes of these three restoration types, in terms of durability, aesthetics and cost effectiveness for the treatment of front baby teeth. The purpose of this pilot study is to evaluate the clinical performance of two types of NuSmile crowns compared to composite crowns in treating large multi-surfaced cavities on front baby teeth.
