“…Therefore, the choice of root canal filling materials and obturation technique is important. Thermoplastic obturation techniques have been reported to be advantageous for the management of irregular root canals (Çelikten et al, ), whereas the single‐cone technique (SC) has gained popularity due to its easy handling, short procedure time, and low cost (Cavenago et al, ; Tasdemir, Yesilyurt, Ceyhanli, Celik, & Er, ). The present study aimed to evaluate the canal filling quality performed with SC and warm vertical compaction technique (WVC) in mandibular molar teeth with band‐shaped isthmuses.…”

The present micro‐computed tomography (micro‐CT) study compared the presence of voids in the band‐shaped isthmuses obturated by warm vertical compaction (WVC) and single‐cone (SC) techniques. Twenty mesial roots from mandibular first molar teeth showing a band‐shaped isthmus were selected and assigned into two groups based on their preoperative anatomical dimensions (n = 10), according to the filling technique: WVC or SC. Post‐filling micro‐CT scanning was performed. The percentage volume of root canal filling materials and voids were calculated and data were analyzed using the Mann–Whitney U test with a significance level of 5 and 95% confidence interval. Mean percentage volumes of filling materials and voids were 86.88 ± 8.53 and 13.11 ± 8.53 for the WVC group, 84.39 ± 8.30 and 15.60 ± 8.30 for the SC group, respectively, with no significant difference between them (p > .05). Neither WVC nor SC produced void‐free root canal fillings in the band‐shaped isthmuses and both techniques resulted in a similar quality of root canal filling.

Micro-CT assessment of the sealing ability of three root canal filling techniques

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)

“…Using confocal laser scanning microscopy (CLSM), gap distribution was significantly higher, and gap thickness were significantly larger in canals that were obturated with the polyacaprolactone-based filling material and its accompanying sealers, when compared to roots obturated with gutta-percha and an epoxy resin-based sealer (Figure 3) [130]. Another CLSM study came to the same conclusion that obturation of root canals with gutta-percha using non-bonding techniques resulted in significantly more gap-free regions, when compared with the use of the polycaprolactone-based material and its accompanying self-etching sealer [131]. Unlike leakage, interfacial gaps are clinically relevant because as little as 1% shrinkage of root canal sealers can result in gaps that are large enough for bacteria penetration [132].…”

Ability of new obturation materials to improve the seal of the root canal system: A review

Objectives New obturation biomaterials have been introduced over the past decade to improve the seal of the root canal system. However, it is not clear whether they have really produced a three-dimensional impervious seal that is important for reducing diseases associated with root canal treatment. Methods A review of the literature was performed to identify models that have been employed for evaluating the seal of the root canal system. Results and Significance In-vitro and in-vivo models are not totally adept at quantifying the seal of root canals obturated with classic materials. Thus, one has to resort to clinical outcomes to examine whether there are real benefits associated with the use of recently-introduced materials for obturating root canals. However, there is no facile answer because endodontic treatment outcomes are influenced by a host of other predictors that are more likely to take precedence over the influence of obturation materials. From the perspective of clinical performance, classic root filling materials have stood the test of time. Because many of the recently-introduced materials are so new, there is not enough evidence yet to support their ability to improve clinical performance. This emphasizes the need to translate anecdotal information into clinically relevant research data on new biomaterials.
