“…In several studies, different dentin bonding agents have been used as root canal sealers and their sealing abilities have been compared with common sealers. However, all bonding agent studies have had problems in working properties, radiopacity, and lack of removability when used for endodontic purposes (12,(19)(20)(21). This was expected because the materials studied were not manufactured with the intention of using them within the root canal system (22).…”

The aim of this study was to compare the apical leakage of roots obturated with gutta-percha using either an epoxy resin sealer (AH26) or a dual cure dentin binding agent (Excite DSC) as sealer in the presence or absence of smear layer with fluid filtration method. The canals of eighty-six, single-rooted premolars were instrumented until a #40 K-file fit at working length and then randomly divided into four groups (n = 20) with the remaining six used as controls. Groups 1 and 2 were filled with gutta-percha using AH26 as sealer; groups 3 and 4 were filled with guttapercha and Excite DSC as sealer. Groups 1 and 3 were smear layer-positive, while group 2 and 4 were designated as smear layer-negative. After 3 days and 3 months, the samples were connected to a fluid filtration system. Analysis of data with the paired t-test showed that microleakage in AH26 groups (with and without smear layer) decreased significantly at 3 months compared to 3 days; however, in the DBA groups, the amount of microleakage at 3 days and 3 months was not significantly different. According to the results of this study, DBA (Excite DSC) had better apical sealing ability and could be applied clinically. (J Oral Sci 51,

“…Also, AH Plus (an epoxy resin sealer) exhibited less leakage than Panavia F (a DBA) with dye penetration method (24), whereas Scotchbond (another type of DBA) had better sealing properties than Tubliseal (19). Researchers indicated that the use of Panavia F is contraindicated as root canal sealer.…”

“…Especially Tubuli-seal/wet (Group 9) group presented the highest leakage values and these results are in accordance with ZnO-eugenol based sealers that showed poor sealing and adhesive properties to dentin in some other investigations. 25,26 In an aqueous environment, ZOE based sealers exhibited continuous solubility. This response was interpreted as water hydrolyzed the zinc-eugenolate into ZnO or Zn(OH)2 and eugenol that were detected as a slow, continuous loss of mass.…”

Objectives: To compared the effect of different levels of moisture of root canal on the sealing ability after filling with four different types of sealer. Materials and Methods: Single-rooted teeth (n = 90) instrumented to and apical size of 0.06 / 45 were randomly assigned to 12 experimental groups (n = 7 per group), positive/negative control groups (n = 3 per group). The teeth of the experimental groups (a. DRY; b. PAPER POINT DRY; c. WET) were obturated with sealer (Group 1-3: Sealapex; Group 4-6: AH plus; Group 7-9: Tubuli-seal; Group 10-12: EndoRez) and warm vertical compaction method. After 7 days in 37℃, 100% humidity, the coronal-to-apical microleakage was evaluated quantitatively using a glucose leakage model. The leaked glucose concentration was measured with spectrophotometer at 1, 3, 7, 14, 21, and 30 days. Data were recorded ad mmol/L and statistically analysed with the two-way ANOVA and Duncan test (p = 0.05). Results: Throughout the experimental period Tubuli-seal/WET (Group 9) showed the highest mean cumulative glucose penetration (178.75 mmol/L), whereas AH plus/DRY (Group 4) had the least (20.78 mmol/L). Conclusions:The results of this study demonstrated that the moisture condition of root canals at the time of obturation and the type of sealer that was used had a significant effect on leakage and sealing ability. Thus drying procedure according to sealer types is a critical step and should not be missed in endodontic treatment.

“…Several studies 1,7,8,13) have evaluated the potential of using dentin bonding agents and resins as root canal filling materials. The penetration of the dentin adhesives into the prepared dentin creates a mechanical interlocking and chemical bonds to dentin to create bond strength.…”

“…Although many different filling techniques and materials have been used in order to obtain a adequate seal, a complete seal of the entire root canal is impossible 1) . The smear layer is a layer of sludge material formed over the surface of dentinal wall whenever dentin was cut.…”
