“…They are injectable, premixed, radiopaque, zero-shrinkage, insoluble, hydrophilic, and aluminum-free (7). Several techniques may be used to evaluate the quality of root canal fillings, such as radiographic visualization and computed tomography (CT) images (8)(9)(10). Recently, micro-CT (µ-CT) imaging has been used to scan and reconstruct three-dimensional (3D) images that allow accurate assessment of root filling outcomes (2,11).…”

This study used micro-CT to compare three obturation techniques with respect to void occurrence in canals filled with bioceramic sealer. Thirty extracted first mandibular premolars were prepared with a ProTaper Universal system and randomly allocated to three groups. Canals were obturated with gutta-percha and bioceramic root canal sealer, using either single-cone, lateral compaction, or Thermafil filling technique. Each tooth was then scanned with micro-CT. Voids in 2D cross-sectional images and void volumes in 3D images of all root thirds were assessed in relation to obturation technique. There was no significant difference between obturation techniques in the proportion of sections with voids (P > 0.05). However, the results of the obturation techniques significantly differed in relation to root region (P < 0.05). In conclusion, no root filling technique resulted in void-free specimens. Void volumes were highest for the single-cone technique and lowest for Thermafil, in all regions (P < 0.05). (J Oral Sci 57, 361-366, 2015)

“…The success of root canal treatment based on the results of tight filling in the apical and orifice by comparing various root canal filling techniques has been widely reported. 5,24,25 Root canal filling techniques that are commonly used, namely lateral condensation and other relatively new techniques in Indonesia still cause differences of opinion regarding the quality of root canal closure. This may be due to the non-homogeneous gutta perca mass of the lateral condensation technique so that the adaptation that occurs on the root canal wall is not good so that it can increase ink penetration, while the thermal technique using heated gutta perca filler has better adaptation to the root canal wall and can fill the entire space of additional root canals.…”

The Thermafil obturation technique is relatively new. The working time and materials used in this technique are more efficient so that the thermafil obturation technique is more environmental-friendly. The objective of this study was to determine the differences of the root canal leakage between the techniques of thermafil and the lateral condensation root canal fillings. Seventy extracted single teeth straight roots were prepared with step back techniques. The diameter of the apical foramen were standardized by using number 15 file and the length of the teeth were reduced by 1 mm. The root canals were prepared until no.40 as MAC and the last file was no.55. The teeth were randomized and filled with the guttaperca thermafil and lateral condensation technique. The calculation of the leakage was measure by microscope with 30 times enlargement, and statistically analized using the Chi Square test of P<0.05. The study showed that the leakage of the guttapercha lateral condensation technique was not better than guttapercha thermafill technique. The thermafill had more leakage distance than lateral condensation technique.

“…The gold standard for comparison between several obturation procedures is the LC technique (Chokkalingam et al,2011; Goldberg et al,2001; Gordon et al,2005; Xu et al,2007). This technique is applied with GP master cone coated by sealer led to the main root canal, until it reaches the apical stop.…”

“…Although there are different obturation techniques, there is no generally accepted a unique method for all endodontic cases (Yilmaz et al,2009). Cold lateral compaction (LC) technique remains the most commonly used and is the standard technique by which other methods are compared (Anantula and Ganta,2011; Chokkalingam et al,2011). However, there are drawbacks of this technique, as the presence of gaps, excessive amount of sealer, lack of adaptation of the filling material on the surface of the root canal, excessive material consumption, and high time spent (Brayton et al,1973; Eguchi et al,1985; Jarrett et al,2004; Mazotti et al,2008).…”

The aim of this study was to compare the percentage of gutta-percha (PGP) in mesial root canals of mandibular molars obturated with LC (Lateral Compaction) or SC (Single Cone) ProTaper Universal System techniques at different levels of the root. Mesial root canals of 20 human permanent molars with similar anatomical characteristics were instrumented using the ProTaper Universal rotary system technique until the F2 instrument, with 20 canals filled by SC ProTaper Universal technique and 20 canals by the LC technique. The mesial roots were sectioned transversely to 3, 5, and 7 mm from the root apex. Digital images of specimens were obtained at MIC-D digital microscope in increases of 30 to 35X. The gutta-percha area was measured using ImageTool software. Data were analyzed using two-way ANOVA and Bonferroni test (α = 0.05). The SC technique provided greater PGP than the LC technique in the apical third (3 mm) (P < 0.001). In the other thirds (5 and 7 mm) there was no statistical difference between the two techniques regarding the PGP (P > 0.05). There was no statistically significant difference between thirds of the root canal for both techniques (P > 0.05). It was concluded that SC technique provided greater PGP than the LC technique in the apical third of mesial root canals of mandibular molars. There was no difference between the two techniques regarding the PGP in the cervical and middle thirds.
