Introduced by Mc spadden
– This method uses heat to decrease G.P viscosity and increase its plasticity
– The heat is created by rotating a compacting instrument in a slow-speed hp at 8,000-10,000 r.p.m alongside G.P cones inside the canal.
According to Grossman
-Lateral condensation method
-Vertical condensation method
-Compaction method (mcSpadden)
-Stainless steel file method
-Chemically plasticized gutta-percha
-Injection techniques of obturating canals
-Thermo-plasticized gutta-percha method
-Obtura II, Ultrafil
The first visit to the dentist, the dentist will gives you local anaesthesia and remove all the pulp tissue. He will then put a temporary filling material to fill up the empty spaces. This process is called Access Opening. During the second visit, the temporary filling material is removed and root canal material like gutta percha is placed. A temporary filling material is placed again. This process is called Obturation. During your last visit, the temoporary filling material is removed and replaced by permanent filling material like composite/amalgam and a crown preparation is done.
