Clinical Comparison of Three Tooth-colored Full-coronal Restorations in Primary Maxillary Incisors

Area of Science:

• Pediatric Dentistry
• Restorative Dentistry
• Dental Materials Science

Background:

• Evaluating the long-term clinical performance of full-coronal restorations in primary anterior teeth is crucial for maintaining oral health.
• This study compared strip crowns, zirconia crowns, and Luxa crowns in primary maxillary incisors over 9 months.

Discussion:

• Resin strip crowns exhibited more frequent marginal integrity loss and secondary caries compared to zirconia and Luxa crowns.
• Zirconia and Luxa crowns showed comparable and favorable outcomes in terms of surface texture, anatomical form, marginal integrity, discoloration, and secondary caries.

Key Insights:

• Zirconia crowns are the best performing full-coronal restoration for primary anterior teeth.
• Luxa crowns offer a cost-effective and esthetic alternative, performing similarly to zirconia.
• Resin strip crowns are associated with a higher incidence of marginal breakdown and secondary caries.

Outlook:

• Further research could explore longer-term outcomes and patient-reported esthetic satisfaction with these restorative materials.
• Investigating the cost-effectiveness of Luxa crowns compared to zirconia in diverse clinical settings is warranted.
