As dentistry shifts toward a paradigm focused on preserving tooth structure rather than restoring longevity at its expense, minimally invasive treatment options have become essential.  Although these approaches were once considered unpredictable due to concerns about retention, advances in adhesive science and long-term clinical data now support their reliability. Immediate Dentin Sealing has emerged as a critical component in achieving predictable, biologically sound, and clinically successful outcomes while preserving maximum tooth structure.
