Monoblocks in root canals: a hypothetical or a tangible goal.

Area of Science:

• Endodontics
• Dental Materials Science
• Adhesive Dentistry

Background:

• The concept of the 'monoblock' in endodontics, referring to a bonded interface between root canal filling materials and dentin, has gained attention with the rise of dentin adhesive technology.
• Controversy exists regarding whether endodontic monoblocks enhance root filling seal quality and root structural integrity.
• Previous applications of the monoblock concept in restorative dentistry and its subsequent adaptation to endodontics warrant a broader definitional understanding.

Purpose of the Study:

• To broaden the definition of the endodontic monoblock.
• To evaluate the application of this broader definition to past and present materials used for root canal space rehabilitation.
• To discuss the potential of current bondable materials in creating mechanically homogeneous units with root dentin.

Main Methods:

• Literature review of endodontic and restorative dentistry research.
• Analysis of dentin adhesive technology applications in endodontics.
• Discussion of material properties and their interaction with root dentin.

Main Results:

• The review provides an expanded definition of the endodontic monoblock.
• It examines how various materials, both historical and current, align with this broader concept.
• The potential for achieving mechanically homogeneous units with root dentin using contemporary bondable materials is assessed.

Conclusions:

• A comprehensive understanding of the endodontic monoblock concept is crucial for evaluating its clinical benefits.
• Current adhesive materials show promise in creating integrated root canal systems.
• Further research is needed to fully elucidate the long-term effects and clinical efficacy of endodontic monoblocks.
