Background/purpose: Traditional restorative composites require time-consuming incremental layering techniques which poses challenges in pediatric dentistry. SonicFill bulk resin allows for thicker layers to be placed efficiently, reducing treatment time and enhancing filling quality. This prospective, parallel, randomized, controlled clinical study aimed to compare the operative time and outcomes between SonicFill bulk resin and conventional restorative composite for deep proximal restorations in primary molars. Materials and methods: A total of 129 primary molars in patients with proximal deep caries were randomly assigned to two groups. The experimental group (n = 66) received SonicFill bulk resin treatment, while the control group (n = 63) underwent restoration using traditional composite. The operative time was documented, and all teeth were evaluated at 6, 12, 18, and 24 -months post-treatment based on the modified criteria from the United States Public Health Service and radiographic examination score. Results: The operative time for SonicFill resin (137.5 ± 5.2 s) revealed a significant reduction compared to traditional composite (193.5 ± 14.4 s), (t = 29.64, P < 0.05). No significant differences were observed between the two groups in terms of colour match, marginal adaptation and so on. Success rates were 95.2% for the control group and 89.4% for the experimental group (χ2 = 1.44, P>0.05). Conclusion: The SonicFill resin technique has proven to be a viable and time-efficient option for the restoration of primary molars with deep proximal caries. Trial registration: This study was registered in the Chinese Clinical Trial Registry (ChiCTR2200055570) on the date of 13/01/2022. [ABSTRACT FROM AUTHOR] |
