Recurrent decay is the silent killer of a lot of “good” composite work, especially at the gingival floor of a Class II box where patients simply cannot keep things clean. Dr. Michael Miyasaki lays out a practical, repeatable bioactive dentistry workflow designed to boost restoration longevity by improving isolation, controlling bleeding, and building a stronger seal where failures usually start. If you’ve been looking for a clearer clinical playbook for deep direct restorations, this is a step-by-step listen.

We start with field control that actually holds up under real conditions: rubber dam isolation, then predictable hemostasis using Quickstat-Free, a clear aluminum chloride solution that helps stop bleeding without discoloring esthetic areas. From there, we move into the exact sequence for cleaning and etching with Clean and Boost, plus how and when we add Desensimax in deeper preparations to support comfort, antimicrobial protection, fluoride delivery, and long-term bond durability.

The core of the technique is bioactive restorative materials built around bioglass, including Regen Universal Adhesive and a Regen flowable composite liner used as a reservoir. We talk through why this “universal” adhesive is not self-etching, how the liner supports adaptation and margin sealing, and how deep curing with the PinkWave curing light fits into polymerization confidence. You’ll also hear practical handling tips like warming composite (including Exquisite) for better adaptation and using a wetting resin like Seam-Free for cleaner sculpting and contour.

Finally, we get into the decision-making that matters chairside: open sandwich vs closed sandwich, and the remin open sandwich technique that intentionally brings bioactive flowable up to demineralized contact areas to help prevent the next cavity. If this helps you think differently about margins, deep dentin, and adjacent tooth risk, subscribe, share the episode with a colleague, and leave a review so more clinicians can find the workflow.
