Efficacy of Biodentine as an Apical Plug in Nonvital Permanent Teeth with Open Apices: An In Vitro Study

Abstract

The aim of this study was to evaluate the apical microleakage of Biodentine and MTA orthograde apical plugs and to compare the effect of thickness of these biomaterials on their sealing ability. A total of eighty maxillary anterior teeth were used. The apices were removed by cutting with a diamond disc (Jota, Germany) 2 mm from the apical root end in an attempt to standardize the working length of all specimens to 15 ± 1 mm. Both materials were placed in 1–4 mm thickness as apical plugs root canal. Root canal leakage was evaluated by the fluid filtration technique. One-way ANOVA was used in order to determine normality of dispersal distribution of parameters; thereafter, results were analyzed by Kolmogorov-Smirnov test. Overall, between microleakage values of MTA and Biodentine regardless of apical plug thickness, no difference was observed. In terms of plug thickness, a statistically significant difference was observed between the subgroups of MTA and Biodentine (p < 0.05). The apical sealing ability of Biodentine was comparable to MTA at any apical plug thickness.

Bacterial leakage and marginal adaptation of various bioceramics as apical plug in open apex model

“…24,25 One study compared the sealing ability and marginal adaptation of 4-mm thicknesses of several bioceramics used as apical plugs and found that the sealing ability of Biodentine was equal to ProRootMTA, as found in the present study. 26 In contrast to the present study, one study reported no significant microleakage of 3-mm ProRootMTA and Biodentine apical plugs. 26 Several related studies have shown a greater sealing ability of 3-mm ProRootMTA than TotalFill BC RRM putty, 27,28 and a similar adaptation of 3-mm ProRootMTA and TotalFill BC RRM putty.…”

“…Comparisons among ProRootMTA, TotalFill BC RRM paste and RetroMTA at 3‐mm thicknesses indicated inferior sealing ability and marginal adaptation in the present study, which is similar to results in other studies . One study compared the sealing ability and marginal adaptation of 4‐mm thicknesses of several bioceramics used as apical plugs and found that the sealing ability of Biodentine was equal to ProRootMTA, as found in the present study …”

Novel Bioceramic Root Repair Materials: Review of the Literature

“…Biodentine applied as an apical plug in immature teeth has been proven to be equally effective as MTA, regardless of the plug thickness [20]. In this study the fluid filtration technique was used.…”

“…Due to their proper biological and physical characteristics, they may be successfully used as root repair materials in procedures such as retrograde obturation after a root resection [5,24,35], open apices management with an apical plug [20,22] or root perforation repair [21,33]. Thanks to the excellent biocompatibility and bioactivity, they may also be used in vital pulp therapy in endodontic procedures, such as indirect pulp capping or pulpotomy.…”

Effect of ultrasonic activation on dentinal tubule penetration of calcium silicate‐based cements

“…Biodentine is a fast‐setting (~10–12 min) calcium silicate‐based material. Several in vitro studies and case reports have recommended the use of Biodentine as an alternative to MTA due to its similar sealing ability, biocompatibility, the formation of mineralized tissue, superior hydroxyapatite apposition when exposed to tissue fluids and stimulating healing ability of periapical tissue (Bani, Sungurtekin‐Ekçi, & Odabaş, ). However, it has low radiopacity (Kaup, Schäfer, & Dammaschke, ).…”
