Five-year clinical performance of two fluoride-releasing giomer resin materials in occlusal restorations.

Objective: To evaluate and compare the clinical performance of two nano-hybrid giomer restorative composite materials after 5 years.

Materials And Methods: Forty-four pairs of restorations (total n = 88) of a flowable giomer (Beautifil Flow Plus F00; Shofu Inc., Kyoto, Japan) and a conventional nano-hybrid giomer restorative material (Beautifil II; Shofu Inc.
