Evaluation of Marginal Adaptation of MTA, Biodentine, and MTA Plus as Root-End Filling Materials—An SEM Study

Abstract

Objective This study aimed to evaluate adaptation of mineral trioxide aggregate (MTA), Biodentine, and MTA Plus when used as root-end restorative materials using scanning electron microscope. Materials and Methods Forty-five extracted teeth with one root canal were cleaned and sectioned at cementoenamel junction, maintaining a standardized length of 15 mm. Chemomechanical preparation and obturation was done in all the samples, and access was restored with glass ionomer cement (GIC). Root-end cavities were prepared in all the samples after 3-mm apical root end was resected. Forty-five samples were divided into three groups with 15 samples each. Root apices were filled with ProRoot MTA in group I, Biodentine in group II, and MTA Plus in group III. The sample teeth were sectioned for examination of gaps at the margins using scanning electron microscope. The data collected were put to statistical analysis by one-way ANOVA (analysis of variance) and post hoc tests. Results The minimum margin gap score of 2.44 μm was observed in group II (Biodentine), whereas maximum gap score of 5.63 μm was observed in group I (ProRoot MTA); 4.92 μm mean margin gap score was observed in group III (MTA Plus). Conclusion Biodentine showed least margin gap at the interface, so it can be considered as the best root-end filling material, whereas, MTA Plus can be considered as a substitute to ProRoot MTA as a root-end filling material.

Effect of Injectable-Platelet Rich Fibrin on marginal adaptation of Bioactive Materials Used as Direct Pulp Capping; An Experimental Animal Study

“…In addition, MTA pH changes from 10.2 to pH 12.5 in 3 h, result in high alkalinity during setting, also, due to the interaction between MTA and the dentin organic phase, resulting in the deterioration of collagen type 1, and changing the micro-hardness of dentin (25) . These findings are completely in keeping with other studies (26)(27)(28)(29)(30) . Conversely, in some experiments, after MTA capping, a homogeneous zone of crystalline structures was initially found along the pulp-MTA interface (31)(32)(33)(34)(35)(36) , limited samples number in other studies, may be the cause for this difference.…”

Effect of blood contamination on marginal adaptation of cold ceramic and MTA angelus: a scanning electron microscopic study

“…After 24 h, the gap size was significantly smaller in MTA Flow, indicating significantly superior marginal adaptation of MTA Flow compared with other tested materials. Bansal et al [ 29 ] compared the marginal adaptation of MTA, Biodentine, and MTA Plus as root-end filling materials by measuring the gap size using SEM. The gap size was significantly smaller in Biodentine, indicating its significantly superior seal ability and marginal adaptation, compared with the other two materials.…”

Sealing Ability of Different Bioceramic Materials Used to Repair Furcal Perforation: An in-Vitro Spectrophotometer Analysis

“…8 In the present study, a new method for analysis of endodontic microleakage based on filtration rate of glucose was employed as described by Xu et al 7 , a glucose filtration test, where glucose is used as a tracer. 9 A glucose leakage model was chosen for this study because it was possible to quantify endodontic microleakage continuously over time. The total amount of microleakage was the cumulative value of leaked glucose.…”

“…According to Bansal et al 9 MTA Plus had finer particle size and had an advantage of the presence of an anti-washout gel that increases its washout resistance as compared to ProRoot MTA. The result of their study is in accordance to our study where MTA Plus had increased sealing ability as compared to ProRoot MTA.…”
