[Retrograde root filling utilizing resin and a dentin bonding agent: indication and applications]

Area of Science:

• Dental Materials Science
• Endodontic Therapy

Context:

• Traditional retrograde root fillings often require box-like preparations, limiting application in certain anatomical areas.
• Amalgam's limitations in complex root anatomy necessitate alternative restorative materials.

Purpose:

• To introduce and evaluate retroplast, a resin-based material (Gluma and resin), for retrograde root fillings.
• To demonstrate the versatility of retroplast in various challenging endodontic scenarios.

Summary:

• Gluma, a methacrylate-based resin, achieves strong chemical bonding to dentin, enabling its use in retrograde root fillings.
• Retroplast can be applied to slightly concave root surfaces, unlike amalgam, allowing access to previously inaccessible areas.
• Applications include molar roots, root perforations, resorptions, cracks, grooves, defects, lateral canals, thin roots, and covering posts, with potential for satisfactory healing.

Impact:

• Expands restorative options for complex endodontic cases, improving treatment outcomes.
• Offers a minimally invasive alternative for retrograde fillings in challenging root anatomies.
• Facilitates reattachment procedures through dentin/root-cement transplantation.
