Aim: The aim of this in vivo study was to evaluate the surface texture, anatomical form, marginal integrity, marginal discoloration, and secondary caries of three different types of crowns in primary anterior teeth at different time intervals of 3, 6, and 9 months.
Materials and methods: Total 45 primary maxillary incisors were randomly selected and divided into three groups of 15 each: group I—strip crowns (Pedoform strip crowns, 3M, United States), group II—zirconia crown (kids-e-crown, India), and group III—luxa crown (DMG, Germany). All the full-coronal restorations were evaluated at 3, 6, and 9 months. The modified USPHS criteria were used to evaluate different parameters. Data were collected and the nonparametric test (Chi-square) was used to analyze the intergroup data.
Results: Statistically nonsignificant difference was observed for most of the parameters except marginal integrity and secondary caries. Resin strip crowns showed maximum cases with distorted marginal integrity and secondary caries.
Conclusion: Zirconia crown performed best among the three full-coronal restorations. Luxa crown performed similar to zirconia crown. It can be used as an alternative economical esthetic full-coronal restoration for primary maxillary anterior incisors.
Clinical significance: This study illustrates the advantage of the temporization material as a full-coronal restoration option in primary maxillary anterior teeth.
