The main purpose of this study is to present a systematically assessment of wear characteristics of hybrid dental composites. Lanthanum oxide (La 2 O 3 ) nanofillers are an imperative part of fillers in hybrid dental composites to increase their cosmetic features and radiopacity that are added as a second filler along with quartz microfillers. In this research, hybrid nanocomposite samples are synthesized by different content of La 2 O 3 nanofillers to study their effect on surface behaviour, friction coefficient and wear resistance that further discussed using scanning electron microscopy (SEM) images of the wear track and debris. The results provide a significant influence of nanofillers on wear resistance with samples having higher nanofillers showing lower wear resistance; however, coefficient of friction reaches an optimum and increase with higher content. The wear behaviour is also related to micro‐hardness of specimens to find a detailed understanding of wear mechanism.
