To perform a clinical and radiographic evaluation comparing Filtek Bulk Fill high viscosity bulk-fill resins with Filtek Z350 XT nanoparticulate for 1 year.
58 restorations were performed for each material (bulk-fill and nanoparticulate), for a total of 116 restorations. Among these, 42 Class I and 16 Class II restorations were performed for each group, in molars and premolars. Clinical evaluation was performed 7 days (baseline), 6 months and 1 year after restorations, using the World Dental Federation (FDI) criteria. Radiographs were obtained at 7 days and 1 year after the restoration was placed and the radiopacity was measured using Image J software at the same time interval.
Of the 70 restorations available for evaluation at 1 year, the Mann-Whitney and Friedman tests showed no statistically significant difference for the FDI criteria analyzed. Greater radiopacity was observed for bulk-fill resin compared to nanoparticulate (two-way ANOVA, P= 0.022). This same test showed no difference in radiopacity between the groups in the two evaluation periods (P= 0.062). The high viscosity bulk-fill resin composite presented similar clinical performance to nanoparticulate resin in this evaluation period and higher radiopacity was observed for this material when compared to nanoparticulate resin, in both time periods.
The high viscosity bulk-fill resin composite showed similar performance to the nanoparticulate resin during the evaluation period of 1 year. Radiopacity showed high values for the bulk-fill resin when compared to nanoparticulate resin. The bulk-fill resin has potential to be used in posterior teeth.
对Filtek Bulk Fill高粘度大块充填树脂与Filtek Z350 XT纳米复合树脂进行为期1年的临床和影像学评估比较。
每种材料（大块充填和纳米复合）均进行58次修复，共116次修复。其中，每组在磨牙和前磨牙中分别进行42次I类和16次II类修复。修复后7天（基线）、6个月和1年时，采用世界牙科联盟（FDI）标准进行临床评估。在修复后7天和1年时拍摄X线片，并在相同时间间隔使用Image J软件测量不透射线性。
在1年时可用于评估的70次修复中，Mann-Whitney检验和Friedman检验显示，所分析的FDI标准无统计学显著差异。与纳米复合树脂相比，大块充填树脂的不透射线性更高（双向方差分析，P = 0.022）。同一检验显示，两组在两个评估期的不透射线性无差异（P = 0.062）。在该评估期内，高粘度大块充填树脂复合材料的临床表现与纳米复合树脂相似，且在两个时间段内，该材料与纳米复合树脂相比均观察到更高的不透射线性。
在1年的评估期内，高粘度大块充填树脂复合材料的性能与纳米复合树脂相似。与纳米复合树脂相比，大块充填树脂的不透射线性较高。大块充填树脂有用于后牙的潜力。
