“…This behavior is probably because of the high solubility (22) and no presence of hydrophilic characteristics (26). However, with regards to physicalchemical properties, this sealer presented satisfactory results compared to other sealers (7,27).…”

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

et al. 2015

The aim of this study was to evaluate the filling effectiveness and dentinal penetration of the sealers AH Plus, Pulp Canal Sealer EWT, Sealapex and MTA Fillapex applied according to the vertical condensation technique using thermoplastic gutta-percha. Forty singlerooted teeth were selected. After chemical-mechanical preparation and root-canal filling, sections of the root (2, 4 and 6 mm from the apex) were obtained and analyzed by stereo microscopy and confocal laser scanning microscopy. Data were tabulated and statistically analyzed. With regard to the assessment of void spaces in the filling material at 2 mm from the apex, the sealers showed similar results, but at 4 and 6 mm from the apex, MTA Fillapex had inferior performance compared to AH Plus (at 4 mm), Pulp Canal Sealer EWT (at 4 and 6 mm) and Sealapex (at 6 mm) (p<0.05). With regard to the penetration into dentinal tubules at 2 mm from the apex, the sealers also showed similar results, but at 4 and 6 mm Pulp Canal Sealer EWT had an inferior performance compared to MTA Fillapex and AH Plus, respectively (p<0.05). All four sealers were found to be similar regarding adaptation of the filling material to the root canal walls, except the MTA Fillapex, which showed failures at 4 and 6 mm from the root apex. With regard to the ability to penetrate into the dentinal tubules, the sealers were found to be equivalent, except for the Pulp Canal Sealer EWT as it had poorer results at 4 and 6 mm compared to MTA Fillapex and AH Plus, respectively.

“…Thus, considering MTA Fillapex, a paste-topaste sealer, two chemical reactions have been identified as being responsible for the setting and physical-mechanical properties of this material: the progressive hydration of orthosilicate ions occurs followed by a reaction between MTA and salicylate resin (21,27). This allows the formation of an ionic polymer containing calcium silicate particles, which reacts with water (7,29). The final reaction leads to the formation of calcium hydroxide and a nanoporous amorphous calcium silicate hydrate gel that polymerises and creates a solid network (29).…”

“…This type of treatment should be taken into consideration because of the biological advantages it provides, such as reported good long-term prognosis in patients during the early stages of maxillary development as well as in adults with prosthetic and/or orthodontic needs (6)(7)(8).…”

“…Due to their biological properties, this type of root sealer is capable to release calcium ions and hydroxyls that increase the pH (4)(5)(6)(7)(8) and induces the repair of the affected area through the neo-tissue formation (9). Although calcium-based sealers present excellent biological properties, several studies have reported their high solubility (8,10) and weak or no adhesion to dental tissues (11), factors that determine the outcome of root canal treatment. In attempt to overcome these drawbacks, low solubility calcium alternative sources, such as mineral trioxide aggregate (MTA) have been tested as components of new endodontic sealers (7,8,12).…”

The advantage of replacing the calcium hydroxide by MTA is the possibility to control or, at least, to reduce the excessive solubility of currents sealers without loss the desirable biological properties (13).…”

The aim of this study was to synthesize and evaluate physicochemical properties of a new salicylate derivative in experimental calcium-based root canal sealers. Two salicylate derivatives were synthesized for the transesterification reaction of methyl salicylate with two different alcohols (1,3-butylenoglicol disalicylate-BD and pentaerythritol tetrasalicylate -PT) in molar ratio 1:3 and 1:6, respectively. The products (BD and PT), were characterized by Fourier Transform Infrared Spectroscopy (FTIR) and Nuclear Magnetic Resonance spectroscopy (RMN). Calcium-based experimental sealers were prepared with the same catalyst paste (60% of MTA, 39% of n-ethyl-o-toluenesulfonamide, and 1% titanium dioxide) and four different concentrations of BD and PT in the base pastes
