目的：本研究测试了 2% 洗必太 (CHX) 不会影响两种牙本质粘合剂 XP Bond (XPB) 和 XENO V (XEN) 的 18 个月临床性能的假设。 材料和方法：共选择 120 例非龋性宫颈病变 (NCCL) 并分为 4 组：(1) XPB； (2)申请XPB之前的CHX； (3) XEN； (4)CHX先于XEN的应用。所有修复体均使用混合复合树脂 Esthet.X。两名评估员使用北卡罗来纳大学 (UNC) 修改的 USPHS 标准在 6 个月和 18 个月时对修复情况进行盲法评估。统计分析包括 Mann Whitney 和 McNemar 非参数检验 (p < 0.05)。结果：6 个月时，评估了 91 个 (75.2%) 修复体，18 个月时评估了 92 个 (76.7%) 修复体。 XPB 的 6 个月/18 个月总体保留率 (%) 为 100/100，CHX+XPB 为 96.0/95.0，XEN 为 100/91.3，CHX+XEN 为 100/95.8，每次回忆时任何组之间均无统计学差异。从术前条件到插入后 1 周、插入后 6 个月和 18 个月，XPB、XEN 和 CHX+XEN 组对空气的敏感性显着改善。对于 CHX+XPB 组，仅术前情况和插入后 1 周之间存在统计学显着差异。所有组的边缘适应均恶化，但未发现统计学上的显着差异。所有其他标准在统计学上保持相似。结论：在牙本质粘合剂之前应用 CHX 不会影响两种粘合剂的 6 个月/18 个月临床表现
Purpose: This study tested the hypothesis that 2% chlorhexidine (CHX) does not affect the 18-month clinical performance of two dentin adhesives, XP Bond (XPB) and XENO V (XEN).Materials and Methods: A total of 120 noncarious cervical lesions (NCCL) were selected and assigned to 4 groups: (1) XPB; (2) CHX prior to the application of XPB; (3) XEN; (4) CHX prior to the application of XEN. A hybrid composite resin, Esthet.X, was used for all restorations. Restorations were evaluated blindly at 6 and 18 months by two evaluators using the University of North Carolina (UNC)-modified USPHS criteria. Statistical analyses included the Mann Whitney and McNemar nonparametric tests (p < 0.05).Results: At 6 months, 91 (75.2%) restorations were evaluated, while 92 (76.7%) restorations were evaluated at 18 months. The 6-month/18-month overall retention rates (%) were 100/100 for XPB, 96.0/95.0 for CHX+XPB, 100/91.3 for XEN, and 100/95.8 for CHX+XEN with no statistical difference between any pair of groups at each recall. Sensitivity to air improved significantly for groups XPB, XEN, and CHX+XEN from pre-operative conditions to 1 week after insertion, to 6 and to 18 months after inserting. For group CHX+XPB, there was a statistically significant difference only between pre-operative conditions and 1 week after insertion. Marginal adaptation deteriorated for all groups, but no statistically significant differences were found. All other criteria remained statistically similar.Conclusion: The application of CHX prior to the dentin adhesive did not influence the 6-month/18-month clinical performance of the two adhesives
