In the past, many interesting techniques and materials attempted to fill the canal space. Gutta percha was the favorite dating back 180 years. Why gutta percha? Inert gutta-percha and a thin layer of sealer was to compensate for sealer shrinkage on setting. To achieve this aim, two techniques were introduced, lateral and warm vertical condensation. Recent attempts have been made to improve the seal of the filling, including a resin bonding approach and a new bioceramic sealer used as the main filler with a cold hydraulic technique. Does the evidence show improved outcomes? This talk will discuss and evaluate if our approach to root filling and to hypothesise on how additional improvements may be made.

Learning Objectives:

Recount in general, the historical evolution of obturation materials and techniques
Describe the current status of obturation and describe the experimental evidence of effectiveness
Explain the prediction of what new materials and/or techniques that are likely to evolve
