目的：本研究的目的是比较两种修复技术和材料对后恒牙龋坏的2年临床效果。方法和材料：在签署知情同意书后，30例年龄在7 - 16岁之间的患者接受了两种1级修复，根据制造商的说明，使用两种系统之一对恒牙第一或第二磨牙的洞进行修复：增量放置的传统后牙复合树脂（Herculite Ultra，Kerr）和超声树脂放置系统（SonicFill，Kerr）与单组分自酸蚀粘合系统（Kerr）。根据美国公共卫生服务修订的标准，两名盲法观察员在三个时间点（基线、1年和2年后）评价了缓解情况。使用Kruskal-Wallis检验和Mann-Whitney U检验比较修复系统的临床性能。结果：修复系统在2年时显示出相似的临床性能。在2年结束时，在两组中，一个修复体的边缘染色阿尔法评级下降。在同一时期，传统组中的两个置换和SonicFill组中的一个置换在颜色匹配和表面粗糙度评分方面获得了Bravo评级。结论：在临床成功率方面，超声树脂置入系统表现出与增量置入传统复合树脂相似的结果。考虑到在单层中提供高达5 mm的优势以及粘度的可调节性，整体填充复合材料置换似乎是后1类复合材料置换的良好替代方案。临床相关性：这项研究表明，一种用于整体填充技术的新型牙科材料表现出与增量放置复合树脂相似的临床成功。
Objective: The objective of this split-mouth randomized controlled study was to compare the 2-year clinical performance of two restorative techniques and materials for posterior permanent carious teeth. Method and Materials: After signing informed consent, 30 patients aged between 7 and 16 received two Class 1 restorations on cavities on permanent first or second molar teeth performed with one of two systems: incrementally placed conventional posterior composite resin (Herculite Ultra, Kerr), and sonic-resin placement system (SonicFill, Kerr) with single-component self-etch adhesive system (Kerr) according to the manufacturers' directions. Two blinded observers evaluated the restorations at three times (baseline, and after 1 and 2 years) according to the US Public Health Service modified criteria. Kruskal-Wallis test and Mann-Whitney U-test were used to compare the clinical performance of the restorative systems. Results: The restorative systems showed similar clinical performance at 2 years. At the end of 2 years in both groups, one restoration's marginal staining Alpha ratings decreased. In the same period, two restorations in the conventional group and one in the SonicFill group received Bravo ratings for color match and surface roughness scorings. Conclusion: The sonic-resin placement system demonstrated similar results to incrementally placed conventional composite resin in terms of clinical success. Considering the advantages of providing up to 5 mm in a single layer, and the adjustability of the viscosity, bulk-fill composite restorations seem to be a good alternative to posterior Class 1 composite restorations. Clinical Relevance: This study suggests that a new dental material for bulk-fill technology exhibits similar clinical success to incrementally placed composite resin.
