HERNANDEZ VIGUERAS, S.; PINEIRO MIRANDA, S.; ARACENA ROJAS, S.  e  ALCANTARA DUFEU, R.. Comparison of the sealed quality of the root canals filled with a Flow System Technique versus lateral compactation technique. Av Odontoestomatol [online]. 2008, vol.24, n.4, pp.255-260. ISSN 2340-3152.

The aid of this study is compare the sealed quality of root canals filled with two obturations systems, GuttaFlow or Flow System Technique (GF) and Lateral Compactation Technique (LC). Methodology: Forty-four palatal roots of molar teeth were prepared and divided randomly in two groups to be obturated with the flow system technique and Lateral Compactation Technique. The samples were radiographed and cut cross-sectionally by roots thirds for its microscopic evaluation. The obturations quality parameters evaluated were extension obturation, adaptation to the walls of the root canal and presence of pores/fissures/vacuolas inside the obturation. Results: No statistical difference amongst the filling techniques except between adaptation to the walls of the root canal in medium and cervical thirds and absence of pores/fissures/vacuolas in cervical third in which LC displayed better results. Conclusions: The new flow material obturation it did not demostrated to improve the quality of root obturation to the being compared with the LC technique.
