A Comparison of Primary Maxillary Incisor Zirconia and Composite Resin Strip Crowns: A One-year Feasibility Study.
Purpose: The purpose of this study was to compare one-year clinical outcomes of primary incisor strip crowns (SCs) and zirconia crowns (ZCs) and determine the frequency of pulp therapy associated with each technique.
Methods: Children aged 18 to 48 months were randomly assigned to a ZC group or SC group. Each incisor was rated as intact (I), damaged (D), or requiring treatment (TR) six and 12 months following placement.
Results: Seventy-six ZCs and 101 SCs were placed for 59 participants; ZCs were more likely to be rated I than SCs at six months (odds ratio [OR] equals 4.2; P=0.01) and 12 months (OR equals 4.0; P=0.02). There was no statistical difference in the frequency of pulp therapy between groups (OR equals 0.8; P=0.70). There were no deviations from treatment randomization in either group.
Conclusions: Zirconia crowns were more likely than strip crowns to be rated as intact at six or 12 months after treatment. The frequency of pulp therapy was not statistically different between groups.
