Retention of Flowable Composites Versus Pit and Fissure Sealants in Permanent Teeth. A Narrative Review.

Abstract

Retention of dental materials is a critical determinant of the success and longevity of restorative procedures. This review compares the retention properties of flowable composites and pit and fissure sealants in permanent teeth, two materials commonly employed in preventive and restorative dentistry. Flowable composites, characterized by their low viscosity and strong bonding capabilities, are frequently used for restorative procedures in posterior teeth. Pit and fissure sealants, primarily used to prevent caries, are also widely utilized in dental practice, particularly in young adults and children. This article synthesizes findings from clinical trials, laboratory studies, and systematic reviews to evaluate the retention performance of both materials, considering factors such as bonding strength, material composition, and clinical techniques. The results indicate that flowable composites generally demonstrate superior retention compared to pit and fissure sealants due to their enhanced adhesive properties, better adaptation to tooth structure, and long-term durability.
