“…14,15 The Biodentine group showed the highest pushout strength among the groups, followed by MTA and CN, and the least pushout strength was seen in CEM cement. These results are in accordance with the study conducted by Guneser et al, 30 Tomer et al, 31 and Aggarwal et al 32 The biomineralization capacity of Biodentine can be attributed to the small particle size of Biodentine that can improve the cement penetration and the formation of tags that enhances the dislodgment resistance. [30][31][32] All the factors mentioned above justify the results of this study, which shows the excellent sealing property and pushout strength of Biodentine compared to MTA, CEM cement, and CN.…”

The present study was performed under in vitro conditions, although the best simulation of intraoral conditions was created with available resources, but the oral cavity is a complex structure, thus exact simulation of conditions could not be reproduced, which might have affected the results.…”

Introduction:In endodontic practice, technical accidents are commonly encountered such as furcation perforation. For everlasting success, furcation perforations shall be corrected rapidly with an ideal perforation sealing material. For an ideal perforation sealing material, the desirable properties include an adequate seal, minimal microleakage, good biocompatibility, high pushout strength, stability in blood-contaminated areas, bactericidal, induction of mineralization, osteogenesis, and cementogenesis, radio-opacity and ease of clinical manipulation. Mineral trioxide aggregate (MTA) is the commonly used furcation repair material, but it presents sundry clinical shortfalls for instance prolonged setting time, difficulty in handling, and tooth discoloration. To remodel the attributions of MTA, new materials have been introduced which include Biodentine, calcium-enriched material (CEM) cement, and Cention N (CN). Biodentine is used as a dentin substitute because of its excellent sealing potential, high compressive strength, high pushout strength, less setting time, good biocompatibility, and biomineralization properties. Calcium-enriched material cement is a water-based tooth-colored material that yields a biological glue, is biocompatible, and ability to induce osteogenesis and cementogenesis. Cention N is an "alkasite" restorative material, like compomer or ormocer materials. It is radiopaque and releases ions such as fluoride, calcium, and hydroxyl. Objectives: To evaluate and equate the sealing capability and pushout strength of ProRoot MTA, CEM cement, CN, and Biodentine as furcation perforation repair materials. Materials and methods: A total of 60 extracted permanent mandibular molars were collected, and furcation perforations were made between the roots in a standardized manner. Based on kind of perforation repair material, samples were arbitrarily categorized into four discrete groups having 15 teeth each. In group I, samples were restored with ProRoot MTA. In group II, samples were restored with CEM Cement. In group III, samples were repaired with CN, and in group IV, samples were revived with Biodentine. After which, five samples from each group were selected for sealing ability testing using the dye extraction method by spectrophotometer, five samples from each group were selected for microleakage testing using the dye infiltration method followed by sectioning and evaluation of the sectioned samples by stereomicroscope, and five samples from each group were selected for Pushout strength evaluation by embedding them in acrylic using polyvinyl chloride (PVC) molds and subjecting them to universal testing machine. The data collected was statistically analyzed. Results: The mean spectrophotometric dye absorbance was significantly higher in CN followed by CEM cement and dye absorbance was least in ProRoot MTA and Biodentine. Infiltration loss was significantly higher among ProRoot MTA and Biodentine compared to CEM cement and CN. The mean pushout strength was significantly higher in Biodentine followed by ...

Introduction Treatment of an immature permanent tooth required a special disinfection protocol due to the presence of thin radicular walls, which are prone to fracture. Mineral Trioxide Aggregate (MTA) has been proposed as a root repair material for root canal treatment. The aim of this in vitro study was to compare the push-out bond strength of conventional White MTA cements and second generation NeoMTA 2 in imitated immature roots treated with different disinfection protocols, which are 5.25% sodium hypochlorite (NaOCl), followed by 17% ethylenediaminetetraacetic acid (EDTA), and NaOCl, followed by 20% etidronic acid (HEBP). Methods The root canals of freshly extracted single-root teeth were manually prepared until 90 K-file to imitate immature roots. Roots were randomly divided into four groups (G) according to the disinfection protocol (n = 15 per group). where G1 (NaOCl + EDTA + White MTA) and G2 (NaOCl + EDTA + NeoMTA 2) While G3 (NaOCl + HEBP + White MTA) and G4 (NaOCl + HEBP + NeoMTA 2) All groups were activated with manual agitation. All specimens were incubated for 48 h. The apical third of each root was perpendicularly sectioned to attain a slice of 3 mm thickness. Push-out bond strength values were assessed using a two-way ANOVA and a Student’s t test. Results G3 and G4 that were treated with HEPB showed higher significant push-out bond strength mean values than G1 and G2 treated with an EDTA chelating agent. Irrespective of the chelating agent used, it was found that both NeoMTA 2 and White MTA had no significant influence on push-out bond strength mean values (p ≤ 0.05). Conclusion The combined use of 5.25% NaOCl and 20% HEBP increased the push-out strength values of both NeoMTA 2 and White MTA, rendering them suitable to be used as an alternative chelating agent to EDTA.
