Comparative Study for Microleakage in Three Retrograde Materials for Filling Root End—Biodentine, Mineral Trioxide Aggregate, and Portland Cement: An In Vitro Preliminary Study

Abstract Introduction Insufficient seal of apex is a significant reason for an endodontist’s disappointment. The materials for root-end filling utilized ought to forestall departure of possible pollutants into periapical areas. The objective of this analysis was to compare the fixing capacity of three materials: white mineral trioxide aggregate (MTA), white Portland cement (PC), and Biodentine. This was analyzed through a test checking for dye leakage. Materials and Methods Thirty human teeth having one root were subjected to instrumentation followed by gutta-percha obturation. An apical pit was readied for the material. The tooth samples were then grouped into three trial bunches: Group I, Biodentine; Group II, white MTA; and Group III, white PC. Root-end pits in the test bunches were loaded-up with the exploratory materials. The tooth samples were kept in India ink for a duration of 72 hours. The degree of color infiltration was estimated with the help of a stereomicroscope at 16× amplification. Color entrance was observed in the whole root in vitro. Results The sequelae of this inspection found that Biodentine shows least leakage compared to MTA and PC. Conclusion Biodentine shows less microleakage compared to MTA and PC.

The Difference

AbstractThe aim of this study was to evaluate and compare the sealing ability to obturate oval canals with three thermoplasticizedguttaperchaobturation techniques taking lateral condensation technique as the control. Ninety-five freshly extracted teeth were decoronated at 2mm coronal to CEJ. Biomechanical preparation was done using step back technique. The teeth were divided into three experimental groups of 30 teeth each and one control group of 5 teeth. The group I (control group) was obturated with lateral condensation technique, group II obturated with injectable thermoplasticizedguttapercha technique, group III obturated with thermoplasticizedguttapercha with downpack and backfill technique andgroup IV obturated with core carrier thermoplasticizedguttapercha technique. The sealability of each technique was assessed by a dye penetration method. The roots were given two full layers of nail polish varnish except apical 2mm. Specimens were then immersed in India ink for 48 hours. Robertson’s technique was used to clear the specimens. The linear dye penetration was measured from anatomic apex to the deepest extent of dye penetration in a coronal direction using triocular stereomicroscope at 10 × magnification. The mean dye leakage of group I was 2.6700mm;group II 0.1713mm;group III 3.3977mm; group IV 2.3210mm. When the means of all the four groups were compared using Kruskal Wallis test the difference was found to be very highly significant with the value<.001**, meaning there by that group II is significantly better than the other three groups as far as sealing ability is concerned.

Abstract Introduction Failure in surgical endodontic techniques can occur most commonly due to improper seal in the apical region. The root-end filling material used should not allow the contamination of the periapical tissue. The aim of the present study was to compare the ability of white mineral trioxide aggregate (MTA), white Portland cement (PC) and intermediate restorative material (IRM) for sealing root-end by dye leakage test. Materials and Methods 120 teeth with single root were prepared through instruments. Following obturation, the apex was cut, and a cavity was made. Then, the teeth were divided into four groups (Group I: MTA, Group II: white PC, Group III: IRM, Group IV: control). Cavities made at apex in the first three groups were then filled with the respective materials. Exposure to the dye, India Ink, was then done for a time period of 72 hours. The depth of penetration of dye inside the whole root was then evaluated with a magnification of 16X under stereomicroscope in vitro. Result MTA showed statistically significant difference in sealing ability (p < 0.05) as compared with other materials. Conclusion MTA cement showed better sealing ability. It is an ideal retrograde filling material, because it is a biocompatible material and has a good marginal adaptation as compared with PC which, in turn, showed better sealing ability than IRM.

Introduction: Coronal microleakage is one of the most important factors for the success and longevity of endodontically treated teeth. Aim: The aim of this study was to evaluate in vitro the coronal microleakage in carious and intact teeth obturated with lateral compaction of gutta-percha using the dye penetration method. Materials and Methods: Forty extracted human teeth were allocated to two groups: Group I consisted of 20 intact teeth (10 single-rooted and 10 multi-rooted) and Group II comprised 20 carious teeth (10 single-rooted and 10 multi-rooted). Root canal preparation was performed using the Step-back technique and copious irrigation with 2.5% NaOCl. All root canals were obturated using lateral compaction and AH Plus endodontic sealer. The teeth were coronally filled with either CAVIT only or the combination of GIC and CAVIT, coated with 2 layers of nail varnish and immersed in 50% AgNO3. Afterwards, the teeth were sectioned mesio-distally using a diamond disc and linear dye penetration was evaluated using a stereo loupe with a micrometer scale at x6 magnification. Results: The results showed dye penetration in 70% of teeth filled with CAVIT and in 10% of teeth filled with GIC+CAVIT. The difference was statistically significant (p<0.05). Conclusion: Based on the obtained results, it may be concluded that the least coronal microleakage was observed in intact teeth temporarily filled with the GIC+CAVIT combination.

The purpose of this study was to assess in vitro the efficacy of nickel-titanium K³ rotary files and hand files for removal of gutta-percha and sealer from obturated root canals using either chloroform or chlorhexidine as solvents. Sixty extracted single-rooted bovine teeth with straight, large canals were prepared, obtured and randomly assigned to 3 groups (n=20). The teeth were stored at 37ºC for 1 month and then the gutta-percha and sealer were removed using different techniques, as follows. Group I: size 3 Gates-Glidden drills plus size 30 hand K-files and Hedström files and chloroform; Group II: K³ NiTi rotary files and chloroform; and Group III: K³ NiTi rotary files and 2% chlorhexidine gel. Radiographs were taken and scanned and the images were digitized. The total area of the canal and the area with remaining obturation material were measured in millimeters using a computed image analysis system (ImageLab). Data were analyzed statistically by one-way ANOVA and Tukey test at 5% significance level. The groups differed statistically (p<0.05) with respect to the average percentage of remaining gutta-percha and sealer, presenting the following sequence of effectiveness (from most to least effective): Group I (15.48%), Group II (28.42%) and Group III (35.96%). The findings of this study showed that, despite the technique used for removal of filling material, none of the retreated canals were completely free of gutta-percha and sealer remnants. The use of stainless steel hand files resulted in a lesser amount of filling debris than the use of nickel-titanium rotary instruments.

This study evaluated the influence of time after application of oxalate solutions in reducing dentin hydraulic conductance. Fifty dentin discs were obtained from extracted human third molars and assigned to 5 groups (n=10), according to the desensitizing agent used: Group I: OxaGel; Group II: experimental agent DD-1: Group III: experimental agent DD-2. In Groups IV and V, a placebo gel and deionized water were used as control, respectively. The agents were applied for 3 min, washed out and the hydraulic conductance was measured immediately and at 5-, 15- and 30-min intervals, and after acid etching. Data were analyzed statistically by two-way ANOVA and Duncan's test at 5% significance level. Groups I, II and III did not differ significantly from each other in any of the time intervals (p>0.05). Likewise, Groups IV and V were statistically similar to each other (p>0.05). The active agents reduced significantly dentin permeability in comparison to control groups (p<0.05). Dentin permeability measured in vitro decreased significantly with time regardless of the agent applied (either active or control agents). The results of Group V, in which no dentin desensitizing agent was employed, indicates that the assessment of dentin permeability by this method must be interpreted with caution.

OBJECTIVE: This in vitro study was designed to evaluate the shear bond strength (SBS) of orthodontic metal brackets bonded by direct and indirect techniques. METHODS: Thirty healthy human maxillary premolar teeth were used. The teeth were divided into three groups of 10 teeth each: Group I - indirect bonding with SondhiTM Rapid-Set system (3M/Unitek), Group II - indirect bonding with TransbondTM XT adhesive system (3M/Unitek) and Group III - direct bonding with TransbondTM XT adhesive system (3M/Unitek). After bonding and obtaining the specimens for the study, the specimens were subjected to SBS testing in a universal testing machine (Emic, model DL-500). The Kolmogorov-Smirnov test was applied to ascertain that the data had a normal distribution and the Bartlett test to check whether there was homogeneity of variance. One-factor analysis of variance was performed and, subsequently, Tukey's test for paired means. A 5% significance level was adopted. RESULTS: The results of Group I were 67.6 (N) and 5.9 (MPa); Group II, 68.9 (N) and 6.1 (MPa) and Group III (control), 92.5 (N) and 8.1 (MPa). CONCLUSION: It can therefore be concluded that the means for Group III were significantly higher compared with Groups I and II in both Newton (N) and Megapascal (MPa) values. The means attained by the indirect bonding technique used in Groups I and II, however, exhibited no statistically significant differences.
