Evaluation of Adaptability of Three Different Root Canal Sealers. (In Vitro Study)
Egyptian dental journal, 2021
Introduction: This study aimed to compare Guttaflow bioseal, MTA-Fillapex, and AH plus with regards to their adaptability on dentin surface. Methods: Thirty (n=30) single rooted human teeth were instrumented and divided into three groups according to the type of sealer used (each n=10). All root canals were obturated with lateral compaction technique. Roots were cut longitudinally and evaluated for adaptability using scanning electron microscope (SEM) at 1500x. Five readings were taken for the widest gap distances at the three thirds of the root for each specimen. Results: AH plus group showed less mean values of gap distances than the other groups at apical and middle two thirds, while GuttaFlow bioseal mean gap distance was less at the coronal one third. MTA-F group showed the higher mean values among the three thirds of the root with no significant difference. Conclusion: AH plus showed superior adaptability than GuttaFlow bioseal, while the worst was MTA-Fillapex.
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...
Quality of Root Canal Filling Using a Bioceramic Sealer in Oval Canals: A Three-Dimensional Analysis
European Journal of Dentistry, 2021
Objectives The oval canals may be associated with inadequate debridement, which can affect the quality of the root canal filling, thus the treatment outcome. The aim of the present work was to compare the quality of oval canals fillings using EndoSequence BC sealer with the single-cone technique or cold lateral compaction. Materials and Methods Thirty-eight human single-rooted premolars with oval canals were instrumented to 1 mm from the apical foramen with hand nickel–titanium files, followed by circumferential filing with Hedstrom files. Teeth were paired into two groups based on their micro-computed tomography (CT) morphological parameters. Both groups were filled using EndoSequence BC sealer. The first used a single cone and the other with the cold lateral compaction technique. The voids volume was evaluated by micro-CT and the percentage was calculated for the total length and for the apical 5 mm of each canal. The Mann–Whitney U test was used to assess whether the surface area...

To compare the push-out bond strength exhibited by root fillings performed with either C-Point and Endosequence(®) BC sealer(™) (BC Sealer) or gutta-percha and AH Plus(®) after the instrumentation of oval canals with either the Self-Adjusting File (SAF) System or WaveOne (WO) reciprocating file. Eighty extracted premolars were selected and divided randomly into the following four groups (n=20): Group 1, SAF instrumentation and filling using gutta-percha and AH Plus sealer; Group 2, SAF instrumentation and C-Point and BC sealer filling; Group 3, WO instrumentation and filling using gutta-percha and AH Plus sealer; and Group 4, WO instrumentation and filling with C-Point and BC sealer. Sodium hypochlorite (5.25%) and EDTA (17%) were used as irrigants for all groups. After the sealer was set completely, the teeth were prepared for micro push-out assessment using 1.0 mm-thick root slices. Loading was performed with a universal testing machine at a speed of 0.5 mm/min. Two-way ANOVA and ...

Insufficient apical seal is the significant reason for surgical endodontic disappointment. The root-end filling material utilized should avoid egress of potential contaminants into periapical tissue. The aim of this study was to compare the sealing ability of four root-end filling materials MTA, Portland cement, IRM, RMGIC in teeth with root apices resected at 0 and 45 angle using dye penetration method under fluorescent microscope. Hundred extracted human maxillary anterior teeth were sectioned horizontally at the cement-enamel junction. After cleaning, shaping and obturation with gutta-percha and AH Plus sealer, the tooth samples were randomly divided in two groups (the root apices resected at 0° and 45° to the long axis of the root). The root resections were carried out by removing 2 mm and 1 mm in both the groups. Following which 3 mm deep root-end cavities were prepared at the apices and the root were coated with nail varnish except the tip. The teeth in both the group were ran...
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.
