“…Ideally they should specify whether the teeth included have the effect, and if so measurements should be limited to the bucco‐lingual direction. This may explain the reported wide range of penetration depths (23–2000 μm) of sealers in some previous studies .…”

“…Rhodamine B has been used successfully in many studies as an indicator for sealer penetration . However, the preferential use of Fluro‐6 over rhodamine B to label calcium‐silicate based sealers has been suggested as rhodamine B is said to have a low affinity for calcium in such sealers . Although the use of rhodamine B did not seem to affect the fluorescence of any of the sealers investigated, Fluor‐6 could be used in future studies to label Fillapex MTA and ProRoot MTA.…”

Sealer penetration and adaptation in root canals with the butterfly effect

2017

The butterfly effect is a phenomenon seen in some roots and is related to density of dentinal tubules. The aim was to investigate penetration depth and adaptation quality of root canal sealers and ProRoot MTA into bucco-lingual and mesio-distal aspects of roots with and without the effect. One hundred and twenty teeth were decoronated at the cemento-enamel junction. Canals were prepared and assigned to obturation groups: gutta-percha with a sealer (AH Plus, EndoREZ, Kerr Pulp Canal Sealer, MTA Fillapex) or ProRoot MTA alone (each containing 10 butterfly and 10 non-butterfly roots). Root sectioning yielded coronal and middle samples. Confocal laser scanning and scanning electron microscopy were used to assess penetration and adaptation. Teeth with the effect had greater mean penetration bucco-lingually (766 μm) than mesio-distally (184 μm, P = 0.003). Coronal sections had greater penetration (430 μm) compared with middle (247 μm, P = 0.006). In conclusion, greater penetration in roots with the effect may improve treatment outcomes.

“…Calcium silicate-based sealers (CSBSs) have been recommended owing to their setting ability in a humid environment and their biomineralization activity. CSBSs have similar physical, chemical and biological properties compared to resin-based sealers (Zhang et al 2009, Ersahan & Aydin 2010, Jeong et al 2017, Silva Almeida et al 2017. The application of CSBSs with a single-cone technique can provide homogeneous root fillings.…”

Aim To compare the removal of root fillings in extracted teeth using the ProTaper Universal Retreatment system (PTUR) followed by a supplementary preparation with the XP‐Endo Finisher file. Methodology The mesiobuccal root canals of 30 extracted mandibular first molars were instrumented with ProTaper Universal NiTi files up to F2 and filled with one of the following sealers using a single‐cone technique (n = 10): AH Plus, NeoMTA Plus and EndoSequence BC. The root fillings were removed using the PTUR system with additional apical preparation using ProTaper F2 and F3 files. Then, an additional preparation with an XP‐Endo Finisher file was performed. The samples were scanned using micro‐CT before and after retreatment and again after the use of the XP‐Endo Finisher to assess the volume of remaining filling material. Data were analysed by Kruskal–Wallis and Friedman's two‐way analysis of variance tests with Bonferroni correction. Results No significant difference in the initial filling volume was observed amongst the groups (P > 0.05). The amount of filling materials in each group decreased significantly after retreatment with rotary files (P < 0.05). After initial retreatment, the volume of the remaining filling amongst the groups was similar (P > 0.05). Additional preparation with the XP‐Endo Finisher improved the removal of filling materials regardless of the sealer type (P < 0.05). Conclusions In the mesiobuccal root canals of extracted mandibular first molars, additional preparation using an XP‐Endo Finisher file, after using the PTUR system and F3 ProTaper instruments, enhanced the removal of filling materials from root canals.

“…Due to lack of similar studies, findings of this study were compared with in vitro studies that investigated the dentinal tubule penetration of sealers in the absence of a separated instrument (Kuci et al, ; Ravindranath et al (); Jeong, DeGraft‐Johnson, Dorn, & Di Fiore, ; Weis et al, ) or those studied the sealing properties of different obturation systems applied over apically separated instrument (Altundasar, ; Taneja, Chadha, Gupta, & Gupta, ). The results of this study showed that at the 3 mm level, the sealer penetration depth into the dentinal tubules was not affected by the obturation technique.…”

The effects of different obturation techniques on calcium silicate-based sealer penetration in the presence of apically separated rotary files were evaluated. Forty-eight extracted mandibular incisors were used. ProTaper F2 rotary files were separated at the apical thirds. Samples were divided into four groups (n = 12) according to obturation technique used: (a) cold lateral compaction (CLC); (b) single cone; (c) bulk-fill (BF) without a core material; and (d) thermoplastic injection (TI). Specimens were sectioned horizontally at 1 and 3 mm from the apex and studied using a confocal scanning laser microscope. The maximum tubule penetration depth and percentage of penetration were measured. Data were statistically analyzed using parametric and nonparametric tests with a significance level of 5%. Regarding penetration depth, a significant difference was found at 1 mm (p < .05), while no significant difference was found at 3 mm (p > .05). At the 3 mm level, all of the obturation techniques showed similar penetration depths. Regarding penetration percentage, the values of the CLC and TI groups were statistically less when compared with the BF group at 1 and 3 mm levels, respectively (p < .05). Under the limitations of this in vitro study, results suggest that the obturation technique may present a significant effect on sealer penetration.
