To evaluate the clinical performance of self versus light-cured universal adhesive in non-carious cervical lesions (NCCLs) after 18 months.
Sixty-eight NCCLs in 28 patients were divided into two equal groups; G1: self-cured universal adhesive (Palfique,Tokuyama,Japan) and G2: light-cured universal adhesive (Single Bond Universal,3 M ESPE,USA). Nanohybrid resin composite (Z350XT, 3 M ESPE, USA) was used as a final restoration. Evaluation for fracture, loss of retention, marginal adaptation and discoloration were done after 1 week, 6,12, and 18 months using FDI criteria. Postoperative sensitivity was assessed after 1 week. Chi-Square and Mann-Whitney tests with statistical significance at (P ≤ 0.05) were used for intergroup comparison,while the intragroup one was performed using the Cochran's Q and Friedman's tests. Survival rate was analyzed using Kaplan-meier and Log-rank test.
Both groups exhibited fracture and retention loss, however, there was statistically significant difference favoring the control group at 6 months (p = 0.0114,0.0016). For secondary outcomes, marginal adaptation and discoloration revealed no significant differences. For postoperative sensitivity, there was a significant difference favoring the control group (p = 0.0007, 0.0011). Palfique had 1.5 Relative-Risk (RR) after 6 months (95% CI 0.5659-4.2617; P = 0.3928) and 20% less risk of failure after 18 months (RR 0.8) (95% CI 0.4618-1.3858; P = 0.4260). Tested adhesives showed equal survival rate (P = 0.5685).
Both adhesives revealed similar clinical performance in restoring the NCCLs after 18 m, however, the early failure was more frequent in the self-cured universal adhesive.
评估自固化通用型粘结剂与光固化通用型粘结剂在非龋性颈部病变（NCCLs）修复18个月后的临床性能。
将28例患者的68个NCCLs平均分为两组；G1组：自固化通用型粘结剂（Palfique，日本德山）；G2组：光固化通用型粘结剂（Single Bond Universal，美国3M ESPE）。最终修复材料采用纳米混合树脂复合材料（Z350XT，美国3M ESPE）。术后1周、6个月、12个月和18个月时，依据国际牙科联盟（FDI）标准对修复体的断裂、固位丧失、边缘适应性和变色情况进行评估。术后1周评估术后敏感性。组间比较采用卡方检验和曼-惠特尼检验，显著性水平为（P≤0.05），组内比较采用 Cochr an's Q检验和Friedman检验。采用Kaplan-meier法和对数秩检验分析生存率。
两组均出现了修复体断裂和固位丧失的情况，然而，在6个月时，对照组的差异具有统计学意义（p = 0.0114，0.0016）。对于次要观察指标，边缘适应性和变色情况未显示出显著差异。对于术后敏感性，对照组的差异具有统计学意义（p = 0.0007，0.0011）。Palfique在6个月后的相对风险（RR）为1.5（95%可信区间0.5659 - 4.2617；P = 0.3928），18个月后的失败风险降低20%（RR 0.8）（95%可信区间0.4618 - 1.3858；P = 0.4260）。所测试的粘结剂显示出相同的生存率（P = 0.5685）。
两种粘结剂在修复NCCLs 18个月后显示出相似的临床性能，然而，自固化通用型粘结剂早期失败更为频繁。
