Non-carious cervical lesions (NCCLs) pose a clinical challenge due to multifactorial aetiology and varied clinical presentations, making it essential to understand their characteristics and treatment modalities to improve treatment outcomes.
To study multifactorial aetiology, clinical characteristics and management using tooth-coloured materials.
Patient's case history was noted to determine aetiology and characteristics of NCCL. Study included 180 teeth, divided in two main groups based on shape of the lesion- Group 1(=90): Saucer/round-shaped NCCL and Group 2(=90): Wedge-shaped NCCL. Groups were further divided in three subgroups as per restorative materials used -Group1a & Group 2a: RMGIC, Group 1b & Group 2b: Flowable Bulk-fill Composite, and Group 1c & 2c: Packable Composite. Assessment was done using Revised FDI Criteria at baseline, 3, 6 and 12 months. Statistics was performed using SPSS version 26.0. Intragroup comparison was done using repeated measures ANOVA followed by Bonferroni post-hoc test. Intergroup analysis was done using independent t-test and one-way ANOVA followed by Bonferroni post-hoc test.
RMGIC demonstrated least postoperative sensitivity in wedge-shaped lesions compared to bulk-fill-flowable and packable composites. All materials showed similar performance in wedge-shaped lesions, but RMGIC exhibited higher surface roughness in saucer-shaped lesions. Packable composites showed more marginal staining in wedge-shaped lesions, while RMGIC had the least staining in saucer-shaped lesions.
Understanding the interplay between abrasion, biocorrosion, and abfraction is crucial for long-term treatment outcomes. The overall performance of RMGIC was better for wedge shaped, and bulk-fill flowable performed better in saucer shaped lesions.
非龋性颈部病变(NCCLs)由于病因多因素且临床表现多样,给临床带来了挑战,因此了解其特征和治疗方式对于改善治疗效果至关重要。
研究多因素病因、临床特征以及使用牙齿颜色材料的管理方法。
记录患者病史以确定NCCL的病因和特征。研究包括180颗牙齿,根据病变形状分为两个主要组——第1组(=90颗):碟形/圆形NCCL和第2组(=90颗):楔形NCCL。每组再根据使用的修复材料进一步分为三个亚组——第1a组和第2a组:树脂改性玻璃离子水门汀(RMGIC);第1b组和第2b组:可流动大块充填复合树脂;第1c组和第2c组:可压实复合树脂。在基线、3个月、6个月和12个月时使用修订的FDI标准进行评估。使用SPSS 26.0版进行统计分析。组内比较采用重复测量方差分析,随后进行Bonferroni事后检验。组间分析采用独立样本t检验和单因素方差分析,随后进行Bonferroni事后检验。
与大块充填可流动复合树脂和可压实复合树脂相比,RMGIC在楔形病变中术后敏感性最低。所有材料在楔形病变中表现相似,但RMGIC在碟形病变中表面粗糙度更高。可压实复合树脂在楔形病变中边缘染色更多,而RMGIC在碟形病变中染色最少。
了解磨损、生物腐蚀和牙齿硬组织折裂之间的相互作用对于长期治疗效果至关重要。RMGIC在楔形病变中的总体性能更好,而大块充填可流动复合树脂在碟形病变中表现更好。
