“…Moreover, the present study showed a greater number of filled lateral or accessory root canals in the "Combined system" group (Table 1). These results are also consistent with previous findings (16,17). Heating and plugging the gutta-percha allows realization of a mould of the canal that increases apical adjustment and propels the sealer cement into the anatomical variations.…”

Forty two single-rooted teeth, preparedwith the Mtwo system, were divided into three groups based on the filling method: control, "Single-cone" (n = 20) (Mtwo gutta-percha single-cone tapered according to the diameter, length and conicity of the preparation) and "Combined system" (n = 20) (BeeFill 2in1). The parameters studied were apical leakage, gutta-percha adjustment, number of voids, presence/absence of sealer, root canal morphology, residual fragments, and filling of lateral/accessory canals. A dye penetration test was carried out (methylene blue). The teeth were embedded in resin, cut transversally and observed. The data were analyzed with non-parametric Mann-Whitney and Spearman tests. Comparative tests between the two groups showed that the "Combined system" was superior in terms of apical leakage (P < 0.01), gutta-percha adjustment (P < 0.05) and filling of lateral/accessory canals (P < 0.05). There were statistically significant correlations between master cone adjustment and root canal morphology (P < 0.01) in the "Single-cone" group. In the "Combined system" group, a relation was observed between the voids and root canal morphology (P < 0.05) and between voids and residual fragments (P < 0.05). The quality of obturation with warm gutta-percha was better than that of the tapered single-cone technique. Root canal morphology influences gutta-percha adjustment. Residual fragments on the root canal reduce sealing ability. (J Oral Sci 54, 99-104, 2012)

“…These studies used whether natural teeth with simulated lateral canals (7,8,9) or resin blocks with artificial lateral canals in attempt to standardize the experimental groups (6,11,12). Resin blocks provide a standardized sample of sufficient size and eliminate the variable effects of instrumentation (11).…”

“…Lateral canals may be obturated primarily with the sealer after vertical and lateral condensation techniques (6,25). Almedia et al (16) investigated filling ability of different sealers (AH plus, Epiphany, Endomethasone, Pulp Canal Sealer, Sealapex) in lateral canals and found that all sealers flowed into 0.1mm artificial canals by using lateral condensation technique.…”

“…Lateral compaction of guttapercha is one of the most accepted root canal obturation techniques. However, its ability to conform to the internal surface of the root canal has been questioned (6). Studies have shown that plasticized guttapercha can easily be moved into the canal irregularities, replicating the irregularities of the root canal system (5, 7).…”

“…These include warm lateral condensation, warm vertical condensation, coated carrier systems, injection systems and thermomechanical compaction. There are only a few studies comparing the effectiveness of all kinds of warmed guttapercha techniques to fill the lateral canals (6,8).…”

Lateral canals establish connection between the main root canal and periodontal ligament. The necrotic tissues and bacteria residing in the lateral canals are difficult to remove by mechanical and chemical cleaning and this influences filling the root canal efficiently and the outcome of the root canal therapy. The aim of this study was to evaluate the filling of artificially prepared lateral canals using six different gutta-percha obturation techniques. For this study, sixty extracted human single rooted teeth were used. Root canals were cleaned and shaped by step back technique. Six lateral canals were prepared in the coronal, middle and apical thirds in each root using #15 engine driven reamer. The teeth were randomly divided into six groups of 10

This in vitro study evaluated the ability of a warm gutta-percha obturation system Thermafil to fill lateral channels in presence/absence of smear layer. Forty single-rooted extracted human teeth were randomly divided into two groups for which different irrigation regimens were used: group A, 5 ml of 5% NaOCl + 2.5 ml of 3.6% H(2)O(2); group B, 5 ml of 5% NaOCl 5% + 2.5 ml of 17% ethylenediamine tetraacetic acid. A conventional crown-down preparation technique was employed. Obturation was performed using epoxy resin-based cement (AH Plus) and a warm gutta-percha plastic carrier system (Thermafil). Specimens were cleared in methyl salicylate and analyzed under a stereomicroscope to evaluate the number, length, and diameter of lateral channels. Lateral channels were identified in both groups at medium and apical thirds. Additional samples were prepared for scanning electron microscopy inspection to confirm the presence of smear layer in group A, and the absence of smear layer in group B. All lateral channels resulted filled in both groups. No statistically significant differences regarding number, length, and diameter were observed between the two groups. Smear layer did not prevent the sealing of lateral channels.
