Some dentists believe that a _____________ sealant is better because of a lower wear rate on occlusal surfaces.

Explanation:
Wear resistance on chewing surfaces comes from the filler content in the sealant. Fillers such as glass or silica strengthen the resin and resist abrasion, so a filled sealant tends to wear less under occlusal forces than an unfilled one. The way the sealant is cured (light-cured vs self-cured) affects setting and handling, not the fundamental wear resistance, and can be true for either filled or unfilled types. Therefore, the option with fillers is favored for durability in high-stress areas, since the added fillers reduce wear over time.
