PURPOSE
To assess periodontal parameters of noncarious cervical lesions (NCCLs) restored with glass-ionomer cement (RM-GIC) and composite resin at baseline, three and six months.
MATERIALS AND METHODS
Eighteen patients with bilateral lesions were included in the study. Lesions (1 mm in depth) were randomly restored with each type of restorative material. Probing depth (PD), relative gingival recession (rGR), relative clinical attachment level (rCAL), visible plaque index (VPI) and gingival bleeding index (GBI) were measured.
RESULTS
No statistically significant differences were found when comparing within groups (p > 0.05). However, the intergroup analysis demonstrated a decrease in GR and rCAL gain for teeth restored with the resin-modified glass-ionomer cement (RM-GIC).
CONCLUSION
Both materials behaved similarly when in close contact with periodontal tissues and did not influence periodontal parameters.
目的
评估在基线、3个月和6个月时，用玻璃离子水门汀（树脂改良型玻璃离子水门汀，RM-GIC）和复合树脂修复的非龋性颈部病变（NCCLs）的牙周参数。
材料与方法
18例双侧病变患者纳入本研究。将深度为1毫米的病变随机用每种修复材料进行修复。测量探诊深度（PD）、相对牙龈退缩（rGR）、相对临床附着水平（rCAL）、可见菌斑指数（VPI）和牙龈出血指数（GBI）。
结果
组内比较未发现统计学显著差异（p>0.05）。然而，组间分析表明，用树脂改良型玻璃离子水门汀（RM-GIC）修复的牙齿，牙龈退缩（GR）减少，临床附着水平（rCAL）增加。
结论
两种材料在与牙周组织密切接触时表现相似，且不影响牙周参数。
