[The Thermafil obturator in endodontics: preliminary study].

A clinical study involving 25 patients and a total number of 42 canals was carried out in the department of Endodontics at the Saint-Joseph University of Beirut and in private practice. The use of the Thermafil device seems to be safe due to the carrier manufactured with a stainless steel medical grade, covered with a layer of gutta-percha alpha phase. The clinical results are satisfactory, the technique is simple, fast and efficient, which confirms the results published in the literature. More investigations are necessary to a better evaluation of the system.
