“…At the apical end as well, the mean leakage associated with Densfil obturation was found to be comparable to that associated with lateral condensation. These results also agree with some previous studies (8,19,22,(26)(27)(28) but not with others (9,10,29,30). Thus, inconsistency in the results prohibits the drawing of meaningful conclusions regarding the performance of the solid core thermoplasticized gutta-percha technique.…”

“…Studies comparing india ink to methylene blue have indicated that methylene blue penetrates deeper than india ink along root canal fillings because of its lower molecular weight (21) and also that the end points of leakage are not as clear (22). Methylene blue particles may also dissolve during the decalcification and clearing processes (23).…”

8 Munksgaard, 1998. Abstract -This study assessed the sealing capacity of two endodontic gutta-percha filling techniques. Thirty-four single-rooted fully developed teeth were endodontically accessed, instrumented and randomly divided into two experimental groups (n=12) and two control groups (~5 ) .In Group A, root canals were obturated using a solid core thermoplastic technique (Densfil), in Group B and Group C (negative control) canals were obturated with laterally condensed gutta-percha, and in Group D (positive control) canals were left unobturated. AH-26 was used as the sealer. Two days later, the teeth were conventionally prepared for testing apical and coronal leakage, immersed in india ink for 5 days and subsequently cleared. The linear coronal and apical extent of dye penetration was measured under a light dissecting microscope. The mean apical leakage for Group A was 1.39 mm, and for Group B 2.76 mm, whereas the mean coronal leakage for Group A was 2.87 mm, and for Group B 4.03 mm. The differences between the groups were not statistically sigdicant (P'0.05).It has been established that endodontic treatment success depends on the root canal being well sealed by the endodontic filling, both apically (1) and coronally (2-6). Currently, there are several endodontic filling techniques available. The most accepted, and the standard with which all other techniques are compared, is lateral condensation of gutta-percha (7). One endodontic filling technique that has gained popularity is the application of thermoplasticized gutta-percha by means of a solid carrier. The sealing capacity of this filling technique has been investigated, however, with conAicting results (8-1 3). The majority of studies have assessed the sealing ability of this technique by testing apical leakage (1 1-13), but the seal at both the coronal and the apical levels has not been investigated.The aim of this in vitro study was to assess the coronal and apical seal provided by thermoplasticized

“…Numerous studies have attempted to assess in vitro leakage (4,11,(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23). However, there is a great deal of variability in the results and minimal consensus as to the most appropriate method to assess leakage (13,24,25).…”

“…In contrast, studies by Lares and ElDeeb 23) and Chohayeb 7) reported that leakage was significantly less with the lateral condensation technique than with Thermafil. In Scott' s study 33) , there was no significant difference between them.…”
