“…These results are in concordance with those of previous studies [20,22,23]. This may be a result of better removal of the smear layer in the coronal thirds than in the apical thirds of root canals, which may, in turn, be because of the fact that there are more dentinal tubules in the coronal area, and the diameters of the tubules in the coronal area are larger than the diameters of those in the apical area [24].…”

Objective: The influence of four root canal filling techniques on the penetration of an endodontic sealer into dentinal tubules and the gutta percha/ sealer ratio (GP/SR) in root canals was evaluated using confocal laser scanning microscopy (CLSM). Material and Methods: Roots of the maxillary central incisors (n=40) were prepared with ProTaper Universal files up to file F5 and assigned to five groups: continuous wave condensation, lateral condensation, single cone, Thermafill®, and negative control group. After root canal filling with gutta-percha and AH26, along with the addition of 0.01% fluorescein, the roots were cut into 2-mm slices. Using CLSM, the specimens were transversely sectioned at 3, 6, and 10 mm from the apex. Results: Sealer penetration was deeper and more frequent at 10 mm than at the 6mm and 3mm for all obturation technique. Penetration was not significantly affected by obturation techniques except single master cone tecnique. Single cone technique demonstrated the lowest sealer penetration at all levels. However, sealer thickness was strongly dependent on obturation technique. Termafill® demostrated superior GP ratio followed by continuous wave condensation, lateral condensation and single cone. Conclusion: In conclusion, the single cone technique resulted in lower sealer penetration than the other techniques, which did not differ significantly from each other. However, sealer thickness was strongly dependent on obturation technique. Termafill® demostrated superior GP ratio followed by continuous wave condensation, lateral condensation and single cone.KeywordsObturation techniques; Dentinal tubule penetration; Gutta percha, sealer ratio; Confocal laser scanning microscopy.

“…The main advantage of Resilon over gutta-percha is that Resilon bonds to the sealer, which in turn bonds to the intraradicular dentin walls, thus creating a monoblock of material which has excellent apical seal and is more resistant to fracture. [ 7 12 13 ] Resilon bonds through the complete length of the root canal[ 8 ] through micromechanical retention by forming a thin hybrid layer to the self-etching primer-treated root dentin.…”

Aims and Objectives:Endodontic treatment is directed to eliminate microbial challenges from the root canal system and to create a complete seal. The aim of this study was to assess the apical sealing ability of resin-based Epiphany-Resilon root canal filling system and to compare it with the sealing abilities of different combinations of AH Plus, gutta-percha, Epiphany, and Resilon.Materials and Methods:One hundred extracted human maxillary incisor roots were treated endodontically. The samples were divided into groups A, B, C, and D, with each group containing 25 samples. Group A: Canals obturated with gutta-percha and AH Plus sealer; Group B: Canals obturated with Resilon and Epiphany; Group C: Canals obturated with gutta-percha and Epiphany; Group D: Control group canals obturated with gutta-percha without a sealer. The sealing ability of each of the obturation techniques was tested using the dye penetration method followed by the clearing method using alcohol. Stereo microscope was used to measure the extent of dye penetration. Statistical data analysis was performed using analysis of variance and Tukey tests.Results:Microleakage was found in all the four groups. Apical extent of mean microleakage was maximum for gutta-percha, followed by Gutta-percha + AH-plus and Gutta-percha + Epiphany, and the least with Resilon + Epiphany. Statistically significant difference (P < 0.01) was seen in the apical leakage.Conclusion:All the samples tested showed microleakage. The “Epiphany soft resin endodontic obturation system” showed a superior result compared to other obturation materials.

“…These findings are in agreement with those of previous studies and can be explained by the differences in numbers and diameters of dentinal tubules. 19,20,21 Sealer penetration may be influenced by dentin permeability, 22 filling technique, 23 and the physical-chemical properties of the sealer. 22 The type of sealer may influence its ability to penetrate dentinal tubules.…”

The aim of this study was to evaluate, by confocal laser scanning microscopy (CLSM), the effect of Ca(OH) 2 dressing on the depth of dentinal tubule sealer penetration and the percentage of sealer-dentin adaptation in the coronal, middle, and apical thirds of teeth filled with methacrylate-based resin sealer (Epiphany). Methods: A total of 30 extracted single-rooted human mandibular incisors were instrumented up to file #40.04 (ProFile), with 1.0% NaOCl as irrigating solution. The teeth were randomly divided into three groups (n = 10): GI = no Ca(OH) 2 dressing (control group); GII = Ca(OH) 2 for 14 days + removal with saline solution and #40 K-file; and GIII = similar to Group II plus 17% EDTA for dressing removal. The Epiphany sealer was labeled with Rhodamine B dye, and all canals were filled with the Epiphany system. Three sections of each tooth were sectioned and viewed under 5X and 40X magnifications. Results: ANOVA and Tukey tests showed significantly lower values of sealer penetration depth in the apical third compared to the middle and coronal thirds (p < 0.05). The deepest sealer penetration was observed in the coronal and middle thirds of Group II. Groups II (93%) and III (86%) had the highest percentage of adaptation compared with Group I (78%) (p < 0.05). Conclusions: Ca(OH) 2 favors the depth of methacrylate-based sealer penetration and the percentage of sealer-dentin adaptation in teeth filled with the Epiphany system.
