Oklahoma Pit and Fissure Sealants State Practice Exam

Which type of resin material is generally preferred for pit and fissure sealants?

1. Unfilled resin

2. Light cured resin

3. Glass ionomer resin

4. Self-curing resin

The correct answer is: Light cured resin

Light cured resin is generally preferred for pit and fissure sealants because it offers several advantages that enhance its effectiveness and utility in dental practice. Light cured resins allow for immediate handling and placement once the curing light is applied, which means the sealant can be cured in a controlled manner, ensuring optimal bonding to the tooth surface. This process provides a strong and durable seal against caries by effectively sealing deep grooves and fissures where plaque can accumulate. Additionally, light cured resins demonstrate excellent wear resistance and can be more aesthetically pleasing, blending well with the natural tooth color. In contrast, other resin options may have limitations. For example, while self-curing resins harden through a chemical reaction that occurs outside the tooth structure, they may not facilitate the same level of control over curing time and may have a longer working time, which can affect placement. Unfilled resins lack the structural reinforcement that light cured materials typically possess, which might result in inferior protective properties. Glass ionomer resins are valuable for their fluoride-releasing capabilities but may not provide the same degree of mechanical strength and durability as light cured resins, making them less favorable for sealing pits and fissures in high-stress areas. Overall, the properties of light
