Depth and percentage of penetration of endodontic sealers into dentinal tubules after root canal obturation using a lateral compaction technique: A confocal laser scanning microscopy study

Abstract

Although Sealapex displayed deeper penetration into the dentinal tubules there was no difference in the percentage of adaptation to the root canal walls among the 3 sealers evaluated.

Filling Effectiveness and Dentinal Penetration of Endodontic Sealers: A Stereo and Confocal Laser Scanning Microscopy Study

“…On the other hand, AH Plus and MTA Fillapex present high flowability, facilitating intratubular penetration (22,23) Although endodontic sealers have shown similar results in some analyses, they did not penetrate the whole extension of the dentinal tubules. The deepest penetration of the sealer in all experimental groups was observed at 6, 4 and 2 mm from the root apex, in this order, which agrees with other studies (9,15,24). These facts may be due to the greater diameter of the dentinal tubules or lesser density of the dentin (25).…”

“…2). Buccal, lingual, mesial and distal points were established in each image based on the proposed methodologies (13)(14)(15) and linear gauge (in µm) of each measurement was made by adding and calculating the mean value between them (Fig. 3).…”

The Influence of Humidity on Intra-tubular Penetration and Bond Strength of AH Plus and MTA Fillapex: An in Vitro Study

“…The adhesive properties and penetrability of some sealers into the dentinal tubules have also been analysed. LSCM has been used for detailed image acquisition, rendering the detection of the distribution of these materials inside the dentinal tubules of the root canal walls (18). As a result, LSCM is considered the ideal method for analysing the adaptation and penetrability of endodontic sealers (18).…”

The sealing ability of a new silicone-based root canal filling material (GuttaFlow): an in vitro study using the percentage of gutta-percha-filled area

“…However, there were no statistically significant differences in PGFA between Groups 3 and 4 at every sectioning level (p>0.05), indicating that accessory GP cones were not necessary when obturating root canals with GuttaFlow. Studies had been conducted to compare the sealing ability of GuttaFlow with other sealers, such as AH26 sealer (Dentsply Maillefer), AH Plus (Dentsply Maillefer), Epiphany (Pentron, Wallingford, CT, USA), and Sealapex (Sybron Endo, Orange, CA, USA) [16][17][18][19][20][21][22] . GuttaFlow was strictly regarded as a sealer in these studies [16][17][18][19][20][21][22] .…”

“…It flows easily into lateral canals and dentinal tubules, hence offering maximum sealing quality. On the assessment of the sealing ability of root fillings system such as GuttaFlow, several methods have been usedsuch as microbial leakage model 16,17) , fluid filtration technique [18][19][20][21] , and confocal laser scanning microscopy 22) . On investigating the sealing ability of different filling techniques, a method that examines the highmagnification micrographs of root canal cross-sections has been used [23][24][25] .…”
