Background:
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.
Aim And Objectives:
To study multifactorial aetiology, clinical characteristics and management using tooth-coloured materials.
Materials And Methods:
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(n=90): Saucer/round-shaped NCCL and Group 2(n=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.
Results:
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.
Conclusion:
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.
