Abstract

Perforation of the root canal system is the second large cause of root canal failure. Failure to seal the perforation defect permits rapid break-down of the periodontium and tooth loss. Hence sealing the defect is paramount. Aims: This study was conducted to evaluate the sealing ability of a new material, self-setting dentine substitute (Biodentine) in furcation perforations and compare it with Mineral trioxide aggregate and glass ionomer cement. Materials and Methods: Fifty five (55) recently extracted permanent lower molars with non-fused well developed roots were collected and intentional perforations were made in the furcation area with a bur. The perforations were repaired with Biodentine for group( A) ,mineral trioxide aggregate (MTA) for group (B) and glass ionomer cement(GIC) for group (C). The specimens were then immersed in 2% methylene blue dye for 48 hour. After their removal, they were sectioned and examined under stereo microscope to evaluate dye penetration. Results: demonstrated that furcation perforation repaired with Biodentine showed least microleakage. Conclusion Biodentine demonstrated better results than MTA and GIC.

Abstract

The aim of This study was to evaluate the effect of some endodontic irrigants on the push-out bond strength Biodentine in comparison with Mineral trioxide aggregate (MTA) and Glass ionomer cement (GIC).Materials and Methods: Mid root dentine of single rooted teeth was horizontally sectioned into 1-mm-thick slices. The canal space of each dentine slice was enlarged with a diamond bur to 1.4 mm in diameter. The samples were divided into 3 groups (n=21)for each, and the following materials were placed, respectively: Biodentine( Septodont, Saint Maur des Foss'es, France),MTA(Dentsply, TulsaDental, Tulsa, OK),and GIC(Medifil, PROMEDICA, Germany).The samples were wrapped in wet gauze for 30 minutes to ensure setting of the materials and then divided into 3 subgroups (n=7)for each, to be immersed into QMix ((Dentsply Tulsa Dental, Tulsa, OK, USA), Bio Pure MTAD (Dentsply Tulsa Dental),and saline solutions for 30 minutes. No irrigant was placed over any test material in the other three subgroups. After incubation for 48 hours, the dislodgement resistance of the samples was measured (with and with exposure to the irrigant solutions) using a universal testing machine. Then the samples were examined under stereomicroscope to determine the nature of the bond failures. Results: The lowest push-out bond strength was observed in the MTA group. Biodentine displayed a significantly higher resistance to displacement than the MTA group. Exposure to QMix, MTAD, and saline solutions did not affect the resistance to displacement of the Biodentine and GIC groups, whereas MTA lost strength after exposure to the irrigant solutions ,but the difference was not significant. Conclusions: The PBS of Biodentine and GIC was not affected by the irrigant solutions. Contact with the irrigant solutions did not have a significant effect on the failure modes of the tested materials

Abstract

Background: This in vitro study was carried out to evaluate the effect of various endodontic irrigants (sodiumhypochlorite, ethylene diaminetetracetic acid and normal saline) on sealing ability of (Biodentine, mineral trioxideaggregate, and amalgam) used to repair furcal perforations.Material and methods: One hundred and twenty extracted human molars with divergent roots were used in thisstudy. A standard root canal access cavity was prepared in each tooth and furcal perforation was made and wasstandardized by using k file size 100 instrument to get a perforation of (1.32mm) in diameter .The teeth were randomlydivided in to three groups of 40 teeth according to the type of material used to repair the perforations (Group A: Thefurcal perforations were repaired with Biodentine, Group B: The furcal perforations were repaired with MTA ,GroupC: The furcal perforations were repaired with Amalgam). Each group was then subdivided into 4 subgroupsaccording to irrigation regimens applied over the repair site (Subgroup 1: without irrigation, Subgroup 2: the pulpchamber was gently irrigated with 10 mL 5.25% Sodium hypochlorite for 10 minutes, Subgroup 3: Pulp chamber wasgently irrigated with 10 mL 17% Ethylene Diaminetetracetic acid for 10 minutes, Subgroup 4: pulp chamber wasgently irrigated with 10 mL normal saline for 10 minutes. Each tooth was coated with two layers of nail varnish andthen sticky wax except 1 to 2 mm around the perforation site. Each tooth was placed in glass vial containing 3 ml ofbuffered Methylene blue dye at (37°C, pH 7) and kept in an incubator for 72 hour at 100% humidity. After dyeapplication, the teeth were washed in running water for 5 min. Each tooth was sectioned longitudinally in abuccolingual direction.Results: The results showed that group A has least mean of dye penetration and the difference was highly significantwith group C and non-significant with group B.Saline and NaOCl increase the sealing of all groups while EDTAsignificantly increased the dye penetration of Biodentine and MTA respectively.Conclusions: Biodentine has the best sealing ability of the tested materials while amalgam showed the highest dyepenetration of all tested materials. Saline and NaOCl increase the sealing ability of Biodentine and MTA where asEDTA decreased the sealing efficacy of MTA and Biodentine

Abstract

Background: Mineral Trioxide Aggregate (MTA) and BiodentineTM cements are new materials with numerous excitingclinical applications. Both have appreciable properties which include good physical properties and the ability tostimulate tissue regeneration as well as good antibacterial effects. The aim of this study was to investigate andcompare the antibacterial effects of MTA and BiodentineTM, when they were mixed with different concentrations ofaqueous solutions of Black Seed extract, against Enterococcus faecalis.Materials and methods: MTA and BiodentineTMwere prepared according to the manufacturer’s instructions. Themethod of Mawlood was followed to prepare the Black Seed aqueous solution. Agar diffusion method on Brain HeartInfusion agar was employed.Twenty, 9 cm diameter, petri-plates with 25 ml of Muller Hinton agar media wereprepared. A sterile spreader was used to inoculate the microorganisms. With a micropipette 0.1 ml of theEnterococcus faecalis suspension was added to the surface of the plates. Within 15 minutes, after inoculation of theplates, 4 cavities, each one measuring 5 mm in diameter and 4 mm in depth, were made in each agar plate. A totalof 20 agar plates were divided into 2 groups consisted of 10 plates each; Group A: each plate contained 4 wellsfilled with MTA alone and MTA mixed with 10%, 30% and 50% of Black Seed aqueous solutions respectively.Group B:each plate contained 4 wells filled with BiodentineTMalone and BiodentineTMmixed with 10%, 30% and 50% of BlackSeed aqueous solutionsrespectively. Next day after incubation, the agar plates were examined for bacterialinhibition zones. With a scientific ruler the diameter of the antibacterial inhibition zones were measured. The datawere recorded and statistically analyzed, by the ANOVA and the Student's t-test.Results: Both cements had antibacterial effects, which were increased with the addition of the aqueous solutions ofBlack Seed extract. The increase in the diameter of Enterococcus faecalis inhibition zones was directly proportionalwith the increase in the concentration of the added Black Seed aqueous extract.Conclusion: Adding aqueous solutions of Black Seed extract to both MTA and Biodentine™ increased their potentialto inhibit the growth of Enterococcus faecalis

Abstract

Aim: Inadequate apical seal is the major cause of endodontic failure, the root end filling material used should prevent ingress of potential contaminants from periapical tissue. Aims: The purpose of this in vitro study was to evaluate the sealing ability of Biodentine (Septodent) when used as a root-end filling material and to compared the result with that of White Mineral Trioxide Aggregate ( MTA) and Glass Ionomer Cement (GIC). Materials and Methods: The root canals of (34) extracted human teeth were instrumented and obturated with gatta percha. Apexes were resected and cavities were prepared to 3mm depth. Teeth were divided randomly into three groups(n=10): first group was retrofilled with Biodentine, second with MTA, third group with GIC, and positive (n=2) and negative (n=2) control groups. Nail varnish was applied to all root surfaces except the tip of the root. Following immersion in basic fuchsine 1% , the roots were sectioned longitudinally and depth of dye penetration was evaluated by stereomicro-scope at 40X magnification. Data were analyzed using one way ANOVA and Duncan›s multiple range test at P< 0.05. Results: In this study, biodentine was determined to be superior than MTA and GIC prevention apical microleakage when used as root-end filling. No statistical significant difference was observed between MTA and GIC. Conclusions: under the conditions of this in vitro study, despite some variation, Biodentine provides a better seal than MTA and GIC when used as retro filling, but along term in vivo study is required to prove it

Abstract

Background: Radiographic discrimination of root end filling materials fromsurrounding tooth structure is clinically relevant for assessing the quality ofretrograde treatment. The present study aimed at evaluating the radiopacity ofBiodentine™ and Pro Root MTA as root end filling materials using a digitalradiography technique.Materials and Methods: Specimens of BiodentineTM and Pro Root MTA testmaterials with 1mm thick and 10 mm internal diameter were prepared for digitalradiographic analysis using an aluminum washer. The radiopacity of theBiodentine™ and Pro Root MTA was assessed using dental radiographyequipment in combination with a phosphor plate digital system and a grey scalevalue aluminum step wedge with thicknesses varying from 1 mm to 10 mm insteps of 1 mm each. The degree of radiopacity of the test materials wereradiographed and compared together with the aluminum step wedge on acomputer screen using image J software. Radiopacity was expressed in mm ofequivalent aluminum step wedge. The radiopacity values of Biodentine™ and ProRoot MTA were statistically analyzed using the one way analysis of variance(ANOVA) and post-hoc test (Bonferroni test), the level of significance was set at0.05 (P<0.05). Results: The radiographic data showed that the degree ofradiopacity of Pro root MTA is significantly higher than that of Biodentine™(P<0.001). The current study reported that the ProRoot MTA showed requisiteradiopacity around 5.86 mm when compared with aluminum step wedge steps,whereas the radiopacity of Biodentine™ determined around 2.46 mm ofequivalent aluminum.Conclusion: The radiopacity of Pro Root MTA is clinically relevant that allows forclear distinction between the material and the surrounding tooth structure enablingit to be used as root end filling material. However, Biodentine showed reducedradiopacity that needs further improvement.
