“…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.…”

Aim: To compare bacterial leakage in root canals obturated with the modified single-cone, lateral condensation, and continuous wave of condensation techniques. Methods: Distobuccal root canals of maxillary molars were shaped up to ProTaper F2 and obturated with modified singlecone, lateral condensation or continuous wave of condensation technique. Two-chamber bacterial model using Enterococcus faecalis was employed for bacterial leakage evaluation for 30 days. The chi-square test was applied to evaluate differences between turbid and non-turbid samples, and the Kruskal-Wallis test was used for evaluating the time necessary for microleakage. A significance level of 5% was set for all analyses. Results: The modified single-cone technique showed leakage in 73.3% of samples, lateral condensation in 66.6%, and continuous wave of condensation in 53.3%, but there were no significant differences among the groups (p>0.05). Conclusions: It can be concluded that the modified single-cone technique shows similar sealing efficacy to that of lateral condensation and continuous wave of condensation technique.

“…Voids along the canal walls are caused by the presence of a gap between the filling material and the dentinal walls and may jeopardize the outcome, because they are in contact with potentially infected canal walls; furthermore, they represent a gap that may promote the failure of the sealer and lead to leakage. 15 Clinically, voids in root fillings are difficult to detect. 16 Many methods (dye penetration, fluid transport and crosssection analyses, etc.)…”

Aim:The aim of this study is to evaluate the influence of final canal taper on the sealing ability of Thermafil by using microcomputed tomography (micro-CT). Materials and methods:Fifty-four single-rooted teeth were instrumented to apical size 40 taper 4, 6 and 8%. Teeth were divided into three groups. All teeth were filled with Thermafil (Dentsply,Tulsa Dental Products). Using micro-CT, roots were scanned and volume measurements of voids at 1, 3 and 5 mm from the apex were calculated using specialized CT software. Measurements were analyzed statistically with ANOVA followed by Bonferroni multiple comparison correction.Results: Data analysis showed that 0.08 preparations provided better results than 0.06 and 0.04% tapered samples especially at 1 mm from the apex. Mean percentage of voids were significantly higher with Thermafil taper 0.06% (p = 0.05). None of the root canals filled teeth were gap free. Root canal preparations with bigger taper exhibited less voids than smaller tapered preparations.Clinical significance: In our daily practice, enlarging the apical third (last 3 mm) of root canals to an 8% taper gives a better sealing ability and thus long-term success for our root canal obturations.

“…Although single-cone technique has been perceived to be less effective in sealing root canals than the gutta-percha warm vertical compaction technique [3], it has recently been revived with the introduction of greater taper master cones that closely match the geometry of nickel-titanium instrumentation systems [4]. Several studies reported that single-cone obturation technique had comparable results to the cold lateral compaction and the thermoplasticized gutta-percha techniques [5][6][7] whereas in other reports, single-cone obturation was found to result in inferior obturation [8][9][10]. The purpose of this study was to compare the long-term clinical and radiographic outcome of matched-taper single-cone filling technique versus gutta-percha warm vertical compaction technique.…”
