Oklahoma Pit and Fissure Sealants State Exam Practice 2026 – Complete Preparation Guide

The correct answer highlights a crucial aspect of sealant application. Polishing pastes often contain glycerin, which can interfere with the bonding process of the sealant. Glycerin can create a barrier between the tooth surface and the sealant material, preventing proper adhesion. This can compromise the effectiveness of the sealant, leading to potential failure in protecting the pits and fissures of the teeth.

Understanding the role of polishing pastes in dental procedures is essential. While they are designed to enhance the finish of dental restorations and clean teeth, the presence of glycerin can mitigate the purpose of sealants, which is to provide a durable barrier against decay. Therefore, avoiding polishing pastes ensures that the application of sealants is more successful and long-lasting.
