A comparative study of the sealing ability of two root canal obturation techniques

“…Several techniques using gutta‐percha have been used in an attempt to achieve a homogenous well‐sealing filling. The cold lateral condensation (CLC) method is still one of the most frequently used techniques (4–6). In recent years, a number of plasticised gutta‐percha techniques have been introduced that have purported to seal the root canal better (5).…”

In recent years, a number of plasticised gutta‐percha techniques have been introduced that have purported to seal the root canal better (5). Obturation systems have been developed using heat‐softened gutta‐percha delivered via injection or with a carrier which delivers heat to cold gutta‐percha cones cemented in the canal (7).…”

Leakage evaluation of three different root canal obturation techniques using electrochemical evaluation and dye penetration evaluation methods

2007

The aim of this study was to compare the apical sealing ability of three different obturation techniques using an electrochemical evaluation and evaluating dye penetration. One hundred and thirty-two maxillary anterior teeth were randomly divided into six groups. There were 20 teeth in each group. The teeth were obturated as follows: Groups 1 and 4 with Thermafil, Groups 2 and 5 with System B, and Groups 3 and 6 with cold lateral condensation (CLC). The apical leakage in these groups was evaluated using an electrochemical method for Groups 1, 2, 3 and a dye penetration method for Groups 4, 5 and 6. In both methods, the lowest mean leakage values were observed for Thermafil and the highest were observed for the CLC groups. The difference between Thermafil and CLC was statistically significant (P < 0.05). In both groups, System B fillings showed moderate leakage and the difference was not significant with Thermafil and CLC groups.

“…Uma raiz, com um único forame apical, tem se mostrado uma exceção, em vez de uma regra 36 , e os canais laterais têm sido encontrados em cerca de 27% a 45% dos dentes 117 . As pesquisas, de um modo geral, também têm demonstrado a presença de múltiplas foraminas, deltas apicais e canais acessórios como componentes desse sistema 1, 24,36,48,49,110,117 . Como resultado, conseguir um selamento tridimensional torna-se bastante difícil 1,110 .…”
