[2025-09-29T19:09:50.086970] [PI reasoning] **Exploring acid etching benefits**

I need to address the topic of acid etching, specifically for enamel in resin composite. The key advantage is that it reduces microleakage by creating micromechanical retention, which forms resin tags and lessens marginal leakage. I should note that while polymerization shrinkage and thermal expansion remain unchanged, porosity in the restorative material isn't influenced either. Overall, the primary benefit is a decrease in microleakage. I'll need to find credible sources for this information.
