Clinical Evaluation of Giomer-Based and Nanohybrid Restorative Materials in Non-Carious Cervical Lesion Class V Restorations over 72 Months: A Randomized, Split-Mouth Clinical Trial

Background/Objectives: This randomized, split-mouth clinical trial compared the 72-month clinical performance of a giomer-based restorative material (BEAUTIFIL II LS) and a nanohybrid restorative composite (Filtek Supreme Universal) in Class V non-carious cervical lesions (NCCLs).

Methods

Forty-nine participants, each with two paired NCCLs, were enrolled (98 restorations) and received both materials under a standardized total-etch adhesive protocol. Clinical performance was assessed at 72 months using modified Hickel/FDI criteria across esthetic, functional, and biological domains, with between-material comparisons performed by paired nonparametric analysis (Wilcoxon signed-rank test) for complete paired observations.
