“…Agreeing with the findings of this investigation, its adequate radio-opacity has been demonstrated in several studies that have used the standard method. [10][11][12][13][14]17,20 By contrast, for the two MTA-based filling materials tested (MTA Fillapex and Endo CPM), which were introduced to the market with the promise of improving clinical performance, the findings demonstrated herein should be confirmed in future investigations.…”

“…However, more recently, proposals to simplify this method have been presented, both to reduce the number of steps with the aluminium stepwedge 18 and to use digital radiographs and software to replace optical densitometry. [7][8][9][10][11][12][13][14][15][16][17]19,20 These changes have occurred not only for endodontic sealers but also for other categories of dental materials. 22 Additionally, further progress towards the improvement of in vitro testing is expected to simulate clinical conditions more closely.…”

“…[3][4][5][6] By contrast, the advantages of digital radiography systems have motivated researchers, and a number of studies have compared the radio-opacity of restorative materials measured from conventional and digital radiographic images. [7][8][9][10][11][12][13][14][15][16][17][18][19][20] Furthermore, in the standard method, the samples are radiographed with no tissue association. The absence of tooth, bone and soft-tissue constitutes an important differential compared with clinical situations in which radio-opacity is investigated, and it could alter the perception of radio-opacity of dental materials.…”

Objectives: To evaluate a new method for assessing the radio-opacity of endodontic sealers and to compare radio-opacity values with a well-established standard method. Methods: The sealers evaluated in this study were AH Plus ® (Dentsply DeTrey GmbH, Konstanz, Germany), Endo CPM Sealer (EGEO SRL, Buenos Aires, Argentina) and MTA Fillapex ® (Angelus Dental Products Industry S/A, Londrina, Parana, Brazil). Two methods were used to evaluate radio-opacity: (D) standard discs and (S) a tissue simulator. For (D), ten standard discs were prepared for each sealer and were radiographed using Digora ® phosphor storage plates (Soredex; Orion Corporation, Helsinki, Finland), alongside an aluminium stepwedge. For (S), polyethylene tubes filled with sealer (n 5 10 for each) were radiographed inside the simulator as described. The digital images were analysed using Adobe Photoshop ® software v. 10.0 (Adobe Systems, San Jose, CA). To compare the radio-opacity among the sealers, the data were analysed by ANOVA and Tukey's test, and to compare methods, they were analysed by the Mann-Whitney U test. To compare the data obtained from dentin and sealers in method (S), Student's paired t-test was used (50.05). Results: In both methods, the sealers showed significant differences, according to the following decreasing order: AH Plus, MTA Fillapex and Endo CPM. In (D), MTA Fillapex and Endo CPM showed less radio-opacity than aluminium. For all of the materials, the radio-opacity was higher in (S) than in (D). Compared with dentin, all of the materials were more radio-opaque. Conclusions: The comparison of the two assessment methods for sealer radio-opacity testing validated the use of a tissue simulator block.

A Comparative Study of the Antibacterial Efficacy of two Natural Irrigating Solutions with Two Different Root Canal Sealers on E-feacalis

et al. 2017

This study aimed to: evaluate the antibacterial efficacy of two natural irrigating solutions (Green Tea, and Propolis) with two different root canal sealers (AH Plus sealer, and Total Fill BC Sealer) against E. faecalis. Methods: One hundred single rooted teeth were selected. All root canals were prepared manually to #50 file. Finally the teeth were sterilized by gamma rays. Each root canal was inoculated with 0.5 ml of E.faecalis. Specimens were divided randomly into two main groups (50 specimens each) according to the irrigating solution; A1 (Green Tea), and A2 (Propolis). Each main group was divided into two subgroups with (25 specimens each) according to the type of sealer used B1 (AH Plus sealer), and B2 (TotalFill BC Sealer). The bacterial sampling counting process was done three times throughout the study. Five specimens from each subgroup were examined by SEM for presence or absence of E. faecalis. Results:The highest mean value of bacterial count was found in (Green tea) (6.50x10x10 ± 1.29x10x10) while the least mean value of bacterial count was found in (Propolis) (with less antibacterial effect 2x10x10 ± 1.33x10x10) with higher antibacterial effect. The highest mean value of bacterial count was found in (AH Plus Sealer) (5.40x10x10 ± 2.44x10x10) with less antibacterial effect while the least mean value of bacterial count was found in (TotalFill BC Sealer) (3.10x10x10 ± 1.54 x10x10) with higher antibacterial effect. Conclusions: Propolis is an effective intracanal irrigant in eradicating E.faecalis. On other hand TotalFill BC Sealer is more effective in reducing E. faecalis.

“…These have been gaining attention because they have greater advantages over the cements considered to be gold standard. 8,9,10 They are biocompatible, atoxic, do not undergo volumetric shrinkage, are chemically stable, have bioactive potential, and are less cytotoxic and genotoxic, 8,9,10,11 and have adequate bonding to root dentin. 12 These sealers require a certain amount of dentin moisture to set and achieve their best bond strength results.…”

To evaluate the influence of rewetting solutions on bond strength to root dentin of conventional gutta-percha (GP) or niobium phosphate glass-based gutta-percha (GNb) associated with a bioceramic sealer. The root canals of 80 human mandibular premolars were prepared using nickel-titanium instruments and irrigation with sodium hypochlorite and EDTA. The teeth were randomly divided into four groups according to the gutta-percha used: GNb or GP associated with EndoSequence BC Sealer (BC) and the solution for rewetting dentin before filling (distilled water; phosphate buffer saline solution -PBS; simulated body fluid -SBF; or no solution). The root canals were filled with a single cone using warm vertical condensation. Micropush-out bond strengths associated with the filling materials in slices from middle root thirds was determined 30 days after root filling. The failure mode was analyzed with stereoscopic lens. The data were statistically analyzed by two-way ANOVA and Holm-Sidak test (p < 0.05). There was significant difference in the types of gutta-percha (p < 0.001) and in the different rewetting solutions (p = 0.003). The interaction between gutta-percha and rewetting solutions was not significant (p = 0.53). The SBF solution provided an increase in bond strength for both gutta-percha solutions. The GNb+BC (3.42 MPa) association increased bond strength when compared with GP+BC (2.0 MPa). The use of SBF as a dentin rewetting solution increased bond strength in the groups studied. Association of GNb with bioceramic sealer was beneficial, increasing the bond strength to dentin when compared with the association with GP.
