Introduction. Restoring primary teeth with extensive decay remains a pressing issue in pediatric dentistry. Modern restoration methods must ensure durability, functional effectiveness, and aesthetic appeal. Therefore, a comparative clinical evaluation of various approaches to restoring primary teeth is of significant scientific and practical interest.
The aim of the study was to conduct a comparative clinical evaluation of the effectiveness of crowns and direct composite restorations in the restoration of primary teeth in children aged 2.5–6 years.
Study materials and methods. The study included 98 children divided into three groups: the study group—tooth restoration with zirconium crowns; the control group—using NuSmile metal crowns; and the comparison group—restorations with Filtek Z250 composite material. Evaluation of clinical outcomes was carried out at periods of 1, 3, 6 and 12 months according to the criteria of preservation of restorations, condition of surrounding tissues, hygienic indicators and aesthetic satisfaction.
Results and discussion. According to the observations, zirconium crowns demonstrated the best performance across all key parameters: high strength and durability, minimal signs of peripheral tissue inflammation, good hygienic properties, and a high level of aesthetic perception by patients and their parents. Metal crowns demonstrated satisfactory functional results but were inferior in aesthetics. Composite restorations demonstrated the least durability and a higher complication rate.
Conclusion. The obtained data confirm the high clinical efficacy and aesthetic appeal of zirconium crowns, making them a suitable choice for widespread use in pediatric dentistry.
