The Research Says: Is Your Old Curing Light Sabotaging Your Fillings

🎓 Business Fundamentals for Dentists Learn how to run your practice like a business — systems, metrics, and execution 👉 https://ryansmithdds.com/business-fun... 📩 FREE Weekly Newsletter for Dentists Real-world dentistry, business insights, and no-BS advice 👉 https://grind.dental Under-curing is one of the most common and overlooked causes of composite failure—and most dentists don’t even realize it’s happening. Your curing light still turns on, still beeps, and still looks bright, but the research shows that output degradation over time can quietly sabotage your restorations. In this episode of The Research Says, Ryan breaks down what actually matters when it comes to curing composite. This isn’t about buying the newest gadget or chasing specs—it’s about understanding real failure thresholds and why “just curing longer” often doesn’t work. You’ll learn why irradiance matters more than time, how low-output curing lights affect degree of conversion, and why restorations can look perfect on the surface while failing underneath. The evidence is clear: once curing light output drops below critical levels, material strength, wear resistance, and longevity all suffer. If you want to stop guessing and start practicing with confidence, this is one of the simplest and most impactful upgrades you can make in your operatory. References: 1. Effect of Light Irradiance and Curing Duration on Degree of Conversion of Resin Composites Provides data showing that higher irradiance leads to higher degree of conversion, especially in deeper/narrower cavities — which underlines why low-powered lights may inadequately cure composite.

Review of Minimum Irradiance Recommendations & Distance Effects Summarizes research–supported guidelines for minimum irradiance levels (often ≥500–550 mW/cm²) and the impact of exposure distance, reinforcing why older or degraded lights below these thresholds are problematic.
