Previous studies have shown that lateral condensation of gutta-percha and sealer can provide an adequate apical seal. The purpose of this study was to compare the level of apical dye penetration when different sealers were used. One-hundred twentyfive teeth with single root canals were biomechanically prepared using the step-back technique and irrigation with EDTAC and 1% NaOCI solutions. The teeth were divided into five groups of 25 teeth each. The control group root canals were filled with laterally condensed gutta-percha and no sealer and the other four groups were filled with laterally condensed gutta-percha and either Apexit, Sealapex, Tubli-Seal, or AH26 sealer. After storage in 100% humidity at 37~ for 48 h, the root surfaces were coated with nail varnish (except at the apex) and placed in 2% methylene blue dye solution and centrifuged at 3 x g for 3 min. The roots were sectioned transversely at 1-mm intervals to determine the following mean levels of dye penetrations: Apexit, 1.67 mm; Sealapex, 2.28 mm; Tubli-Seal, 1.95 mm; AH26, 0.82 mm; and gutta-percha alone, 8.37 mm. This study demonstrated that a root canal sealer should be used in conjunction with laterally condensed gutta-percha and that AH26 sealer provides a significantly better apical seal than the other sealers.
Coronal Leakage of Teeth Root-Filled With Gutta-Percha or Resilon Root Canal Filling Material
Journal of Endodontics
This study compared the micro-leakage of a root canal filled with Resilon or gutta-percha (GP), utilizing either cold lateral condensation or System B. Four experimental groups were used. Group one was obturated with GP using cold lateral condensation, group two with GP using System B, group three with Resilon using cold lateral condensation, and group four with Resilon using System B. Micro-leakage was tested using a two-chamber bacterial method as well as a dye penetration test. Data was subjected to statistical analysis using an ANOVA. A p-value <0.05 was considered as significant. The bacterial micro-leakage test showed no significant difference between GP and Resilon when using Cold Lateral condensation (p = 0.2695) or System B (p = 0.5602). The dye penetration test also showed no significant difference between GP and Resilon using either the Cold Lateral condensation (p = 0.2713) or the System B techniques (p = 0.0767). The ability of GP and Resilon to seal a root canal is ...

Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 2007
Objective. The aim of this study was to measure leakage of 4 resin-based sealers. Study design. Four groups of premolars (n ϭ 60) were prepared using GT Rotary files and the crown-down technique and filled by the single-cone technique with AH26, AHPlus, EndoREZ, and an experimental MBP as sealer. Leakage was measured using the fluid filtration method after 15, 30, and 60 days and determined as L/min -1 .10 psi. Results. Statistical analysis by ANOVA and Tukey HSD test indicated that root fillings with AH Plus and the MBP showed lower leakage values after 15 days (P Ͻ .05). At 30 days, AH26 presented higher leakage values when compared to other sealers (P Ͻ .05). At 60 days, MBP and AH Plus presented the lower leakage values, differing significantly from EndoREZ (P Ͻ .05). Conclusion. It was observed that AH Plus and the experimental MBP showed lower leakage after 60 days than AH 26 and
Apical leakage of epiphany root canal sealer combined with different master cones
European journal of dentistry, 2008
The aim of this study was to assess the apical sealing ability of different core materials used with Epiphany(TM) sealer and to evaluate the effect of Resilon/Epiphany(TM) system on creating an apical mono-block seal. Fifty-five extracted human teeth were used. Forty-five were selected and randomly divided into three groups and ten teeth were used as positive and negative control groups. In Group 1, roots were obturated using Resilon and Epiphany, In Group 2, roots were obturated using tapered single-cone gutta-percha and Epiphany and in Group 3, roots were obturated using Thermafil obturators and Epiphany sealer. The apical leakage was measured using the dye penetration methodology. The teeth were cleared, and the linear extent of dye penetration was measured with a stereomicroscope. Data were analyzed by the one-way ANOVA and Tukey HSD tests. The teeth filled with Thermafil obturators and Epiphany sealer displayed the most apical leakage. The least apical leakage was shown with Re...
Coronal sealing ability of a new root canal filling material
Journal of the Canadian Dental Association, 2007
To date, many different materials have been proposed for root canal fillings, but gutta-percha (used with various types of sealers) has remained the material of choice for over a century. A new root canal obturation system, the Epiphany endodontic obturation system, has been developed to replace gutta-percha and traditional sealers for root canal obturation. The purpose of this study was to evaluate the coronal sealing ability of the new endodontic obturation system. Seventy-two maxillary and mandibular single-rooted human teeth extracted for periodontal reasons were used. The root canals were instrumented using the step-back technique and were irrigated with 5.25% sodium hypochlorite. The smear layer was removed by washing in 10 mL of 17% ethylenediamine tetra-acetic acid (EDTA). The specimens were randomly divided into 3 groups (group 1 to be filled with gutta-percha and AH 26 sealer, group 2 with gutta-percha and AH plus sealer, and group 3 with Epiphany self-etch sealer and Resi...
Evaluation of Apical Sealing Ability of Three Different Root Canal Sealers
Aim: Evaluation of apical sealing ability of Resilon with Epiphany sealer, gutta-percha with AH plus sealerand gutta-percha with MTA fillapex sealer using dye penetration method. Introduction – Success of root canal treatment highly depends of three dimensional obturation of the root canal system. Solid core gutta percha and sealers is preferred method of obturation of the root canal system. None of the available method are capable of providing a fluid tight seal. Material and Methods: Thirty freshly extracted single rooted premolars were taken and randomly divided into three groups. These teeth were then obturated using following methods. Group I-gutta-percha with AH plus sealer, Group II-gutta-percha with MTA fillapex sealer, Group III-Resilon with Epiphany sealer. All specimens were stored in 100% relative humidity for 48hrs. The teeth were then stored in Rhodamine-B dye for 24hrs and then were sectioned and observed under stereomicroscope. Results: Data obtained was analysed using Mann whiteny 'u' test.There was statistically significant difference among the groups. Group III showed minimum dye leakage and group II showed maximum dye leakage. Conclusion: Resilon Epiphany system showed better apical sealing of the root canal as compared to AH plus and MTA fillapex sealer.
Long-term sealing ability of resin-based root canal fillings
International Endodontic Journal, 2010
Aim To evaluate the ability of two resin-based filling materials to provide immediate and long-term sealing of the root canal. Methodology A total of eighty-two human roots were instrumented and filled with AH Plus/gutta-percha or Epiphany/Resilon. Root filled teeth were sealed coronally either with Coltosol or Clearfil SE Bond/Filtek Z250 or were left unsealed. The quality of root canal sealing was assessed by a fluid filtration method performed at immediate and 180-day time intervals. Mean fluid filtration rates were analyzed by three-way repeated measures anova and Tukey post hoc test. Results Specimens filled with Epiphany/Resilon exhibited higher leakage than specimens filled with AH Plus/gutta-percha (P < 0.05), regardless of the coronal sealing condition and period of evaluation. No difference was detected between coronal restorative materials (P > 0.05), whilst leakage in teeth without any coronal restoration was significantly higher (P < 0.05). After storage, a significant decrease in leakage (P < 0.05) was observed in all experimental groups. Conclusions AH Plus/gutta-percha provided superior root canal sealing at both immediate and 180-day time periods. The presence of a coronal seal reduced leakage significantly. Storage of root filled specimens did not disturb the sealing ability of the tested materials.

The purpose of this study was to compare the level of apical leakage between canals filled with gutta-percha/AH-Plus (GP) and the Resilon/Epiphany System (RES), when submitted to two filling techniques. Seventy extracted teeth were instrumented and randomly divided into four experimental groups in accordance with the material and techniques used [lateral condensation and Hybrid technique (HT)] and two control groups. After 7 days in an oven (37 degrees C, 100% humidity), the teeth were immersed in India ink and cleared. Leakage was measured by the NIH imageJ program. With respect to the presence of leakage, there was no difference between the filling techniques (p > 0.05), but there was a statistically significant difference when RES was compared with GP (p < 0.05), which leaked more than RES. With RES, leakage was confined to the apical third and HT could be used to thermoplasticize RES with satisfactory results.
