Gutta Percha and Updated Obturating Techniques

Abstract

Gutta-percha was first introduced as a restorative material and later developed into an indispensable endodontic filling material. It has become one of the most important materials in endodontics, in its development as a field. Over the years, numerous methods have been advocated to obturate the root canal with gutta-percha and sealer. Hence various forms of gutta-percha are available for usage and the current forms are solid core gutta-percha points, standardized, non-standardized, thermo mechanical compactible gutta-percha, thermo plasticized gutta-percha, solid core system, injectable form, and medicated guttapercha. This article describes its origin, its chemistry, its different phases and properties of gutta-percha in term of using in dentistry. The aim of this study was to elucidate the rheological properties of gutta-percha, and to discuss whether the method using guttapercha is proper for obturating the root canal.

Root‐end resection with or without retrograde obturation after orthograde filling with two techniques: A micro‐CT study

“…These results could be attributed to the physical properties of materials used as well as to technical features of obturation techniques. Unlike the SCT, orthograde obturation by means of MTA and thermoplasticized injectable gutta‐percha requires more increments and more clinical passages which could contribute to voids formation [28]. Moreover, the MTA viscosity and its grainy consistency could hinder the condensation of the MTA increments, particularly in the apical region [17, 29].…”

“…This phase of GP is more plastic in nature and thus can flow in small irregularities and dentinal tubules of the canals leading to a better seal of GP to the root canal walls. 23,[30][31][32] • Thermoplasticized GP which gets wedged into irregularities of dentin cannot be easily removed. • It has been reported that thermoplasticized GP technique resulted in an obturation with greater density.…”
