Out of all the materials advocated over the last 150 years for root canal obturation, gutta percha has proven to be material of choice for successful filling of canal from its coronal to apical extent.Though not ideal filling material does not overshadow its advantages so, to minimize its disadvantages there has been continuous improvements in its chemistry,chemical composition and techniques.Chemically gutta percha exists in two distinct crystalline forms alpha and beta .These phases are interchangeable with changing temperature .Traditionally, beta phase gutta percha was used to manufacture endodontic gutta percha points to achieve improved stability ,hardness and reduced stickiness. Recently alpha phase is preferred due to :
* Low Viscosity :GP can flow with less pressure or stress
* Increased Flow : Creating a homogeneous flow
The newer heated thermoplastic gutta percha obturators simplify the whole procedure of obturation . ThermaFlo by equinox is a simple ,fast and effective carrier based heated Gutta Percha Obturation System. The Smooth insertion of single heated obturator assures a predictable three dimensional hermetic seal in the apical ,middle and coronal third of even the most complex canal anatomies.
