Oklahoma Pit and Fissure Sealants State Practice Exam

In terms of sealing properties, what is the main feature of self-adjusting unfilled resin?

1. Increased adhesion

2. Minimal occlusal interference

3. Enhanced color matching

4. Superior strength

The correct answer is: Minimal occlusal interference

The main feature of self-adjusting unfilled resin is that it allows for minimal occlusal interference. This characteristic is crucial because, during the application of pit and fissure sealants, ensuring that the sealant does not disrupt the normal bite or occlusion is essential for patient comfort and functionality. Self-adjusting properties mean that the material can adapt or conform to the contours of the tooth surface, thereby minimizing the potential for any high points that could lead to discomfort or issues with chewing. This feature is particularly important for maintaining the integrity of the sealant while ensuring that the patient’s occlusion remains intact and comfortable after placement. The other attributes, while beneficial, do not specifically focus on the primary sealing quality related to occlusal interference. For example, increased adhesion improves the bond between the sealant and the tooth, but it does not directly pertain to how the sealant interacts with occlusal surfaces. Enhanced color matching is about aesthetic considerations rather than functional performance, and superior strength relates to the durability of the sealant but doesn't address the fitting within the occlusal scheme directly. Thus, the focus on minimizing occlusal interference captures the essential functional aspect of self-adjusting unfilled resin sealants.
