Assessment of a Thermoplasticized Gutta-Percha Delivery System to Effectively Obturate Canals with Varying Preparation Dimensions

Comparison of three obturation techniques with regard to bacterial leakage

“…Lateral condensation is the oldest and still used technique, but it requires professional expertise and demands more time and material for its execution 2 . The thermoplasticized gutta-percha root canal obturation technique is one the most indicated because it is associated with better anatomic filling [3][4] and less quantity of sealer used [5][6][7] , but it lacks longitudinal control and needs special equipment 3 . In this way, the improvement of older and conventional techniques is aimed at enhancing practicality, rapidity and simplicity, which benefit both the patient and the dentist.…”

A comparison of two gutta-percha master points consisting of different phases in filling of artificial lateral canals and depressions in the apical region of root canals when using a warm vertical compaction technique

“…A split-tooth model as described previously was used. (Smith et al 2000, Bowman & Baumgartner 2002, Villegas et al 2005, Collins et al 2006, Karr et al 2007, Yelton et al 2007, Zielinski et al 2008. Two extracted human maxillary central incisors were used to produce two different models for canal filling: the first was the lateral canal split-tooth model; the second was the depression split-tooth model (Fig.…”

Comparação do selamento das técnicas de cone único modificada, condensação lateral e termoplastificada por onda contínua de condensação

“…praticamente como um grupo controle que permitirá compreender os resultados, estabelecendo referências positivas ou negativas na comparação com os demais grupos avaliados. A técnica termoplastificada foi selecionada por ser considerada atualmente como uma das mais indicadas na obturação do sistema de canais radiculares devido à sua propriedade de plastificação da guta-percha (Beatty et al, 1989;Budd et al, 1991;Michailesco et al, 1996;Pommel e Camps, 2001;Jacobson et al, 2002;Epley et al, 2006;Monticelli et al, 2007a;Monticelli et al, 2007b;Yelton et al, 2007;Marciano et al, 2011), e consequentemente melhor preenchimento anatômico, penetração em canais secundários e redução da quantidade de cimento obturador.…”
