The aim of this clinical study is to evaluate the 2-year term results of gingival recession (GR) associated with non-carious cervical lesions (NCCLs) treated by connective tissue graft (CTG) alone or in combination with a resin-modified glass ionomer restoration (CTG+R).
Thirty-six patients with Miller Class I buccal GR associated with NCCLs completed the follow-up. The defects were randomly assigned to receive either CTG or CTG+R. Bleeding on probing (BOP), probing depth (PD), relative GR, clinical attachment level (CAL), and cervical lesion height coverage were measured at baseline, 6 months, 1 year, and 2 years after treatment.
Both groups showed statistically significant gains in CAL and soft-tissue coverage. The differences between groups were not statistically significant in BOP, PD, relative GR, or CAL after 2 years. Cervical lesion height coverage was 79.31% ± 18.51% for CTG and 71.95% ± 13.25% for CTG+R (P >0.05). Estimated root coverage was 91.56% ± 11.74% for CTG and 93.29% ± 7.97% for CTG+R (P >0.05).
Within the limits of the present study, it can be concluded that both procedures provide comparable soft tissue coverage after 2 years of follow-up.
本临床研究的目的是评估单独使用结缔组织移植物（CTG）或联合使用树脂改良型玻璃离子体修复剂（CTG+R）治疗非龋性颈缘病变（NCCLs）相关牙龈退缩（GR）的 2 年期限结果。
36 名患有 Miller 分级 I 型颊侧 GR 并伴有 NCCLs 的患者完成了随访。将缺损随机分为接受 CTG 或 CTG+R。在治疗后 6 个月、1 年和 2 年，测量探诊出血（BOP）、探诊深度（PD）、相对 GR、临床附着水平（CAL）和颈缘病变高度覆盖。
两组在 CAL 和软组织覆盖方面均显示出统计学上的显著改善。两组在 2 年后的 BOP、PD、相对 GR 或 CAL 方面差异无统计学意义。CTG 的颈缘病变高度覆盖为 79.31%±18.51%，CTG+R 为 71.95%±13.25%（P>0.05）。CTG 的估计根覆盖为 91.56%±11.74%，CTG+R 为 93.29%±7.97%（P>0.05）。
在本研究的限制范围内，可以得出结论，两种方法在 2 年随访后均可提供类似的软组织覆盖。
