This research evaluated the periodontal conditions of teeth with restored and non-restored non-carious cervical lesions (NCCLs).
Thirty-seven patients presenting at least two contralateral teeth with NCCL (one restored and another non-restored) were selected. Non-restored NCCL teeth were classified as a control group, while the contralateral teeth restored within at least 3 months with a Class 5 restoration located near the gingival margin were classified as the test group. The periodontal parameters analyzed were visible plaque, probing depth, bleeding on probing, gingival recession, clinical attachment level, and width of keratinized tissue. Restorative parameters such as finishing/polishing, overhanging margins, and terminal restoration level were also examined. Statistical analysis included the comparison of periodontal and restoration parameters between groups as well as associations between these parameters. Data were statistically analyzed by the Wilcoxon, Fisher's exact, Chi-squared, and Mann-Whitney tests. The significance level was set at 5% (α < .05).
Statistically significant differences between test and control groups were observed for visible plaque (P = .002), bleeding on probing (P = .041), and width of keratinized tissue (P = .009). Other clinical parameters such as probing depth (P = .812), gingival recession (P = .571), and clinical attachment level (P = .484), as well their associations did not show any statistically significant differences (P > .05).
Restorative treatment (Class 5) of teeth with NCCL partially influenced the clinical parameters.
本研究评估了有修复和无修复的非龋性颈部病变(NCCL)牙齿的牙周状况。
选取了37例患者,其至少有两颗对侧牙齿患有NCCL(一颗有修复,另一颗无修复)。未修复的NCCL牙齿被归类为对照组,而在至少3个月内用位于龈缘附近的5类修复体修复的对侧牙齿被归类为试验组。分析的牙周参数包括可见菌斑、探诊深度、探诊出血、牙龈退缩、临床附着水平和角化组织宽度。还检查了诸如修整/抛光、悬突边缘和最终修复水平等修复参数。统计分析包括组间牙周和修复参数的比较以及这些参数之间的关联。数据通过Wilcoxon检验、Fisher精确检验、卡方检验和Mann-Whitney检验进行统计分析。显著性水平设定为5%(α <.05)。
试验组和对照组在可见菌斑(P =.002)、探诊出血(P =.041)和角化组织宽度(P =.009)方面存在统计学显著差异。其他临床参数,如探诊深度(P =.812)、牙龈退缩(P =.571)和临床附着水平(P =.484),以及它们之间的关联均未显示出任何统计学显著差异(P >.05)。
NCCL牙齿的修复治疗(5类)对临床参数有部分影响。
