A comparative evaluation of sealing ability of four root end filling materials using fluid filtration method: An in vitro study

Abstract

Aim of the Study:The aim of this study was to compare and evaluate the sealing ability of four root end filling materials mineral trioxide aggregate (MTA)-Plus, Biodentine, MTA (MTA Angelus) and glass ionomer cement (GIC) using fluid filtration method.Materials and Methods:Forty-four extracted, human single-rooted teeth were collected. The crown of each tooth was decoronated 2 mm above the cementoenamel junction. Canals were negotiated, instrumented, obturated using lateral compaction method. The access cavities were sealed with Cavit. Root end resection and apical root end cavity preparations of 4 mm were made in each specimen. The selected roots were then randomly divided into four groups (n = 11) and restored as follows. Group 1 – GIC, Group 2 – MTA (MTA Angelus), Group 3 – Biodentine, and Group 4 – MTA Plus. The apical microleakage of each specimen was assessed using fluid filtration method at 72 h, 1 month and 3 months. Microleakage in each specimen was recorded in mm (millimeter) and converted to μl/min/cm H2O.Results:MTA Angelus showed least microleakage followed by Biodentine and MTA Plus. Least sealing ability was seen with GIC. There was statistically significant difference between all the materials at various time intervals.Conclusion:MTA Angelus showed superior sealing ability as a retrograde filling material followed by Biodentine and MTA Plus.

Efficacy of Mineral Trioxide Aggregate and Biodentine as Apical Barriers in Immature Permanent Teeth: A Microbiological Study

“…Shetty et al 8 evaluated the sealing ability of MTA-Angelus, MTA Plus, biodentine, and glass ionomer cement at 72 hours, 1 month, and 3 months using fluid filtration technique. This study stated that MTA-Angelus had the least microleakage followed by biodentine and MTA Plus.…”

“…2 ). Ten microliters of a culture containing 9 × 10 8 CFU/mL of E. faecalis (ATCC 29212) diluted in 1 mL of brain heart infusion broth solution was placed into each tooth ( Fig. 3 ).…”

“…Biodentine has prominent clinical features as improved sealing ability, enhanced compressive strength, reduced porosity, greater density, bioactivity, rapid formation of calcium hydroxide, biomineralization capability, biointeractivity, and color stability compared to mineral trioxide aggregate. 5 , 7 , 8 The endodontic implications of biodentine are similar to MTA. They thus can be used as a root-end filling material.…”

“…Various techniques for assessing microleakage include the utilization of dyes, irradiated isotopes, air under pressure, fluid filtration, bacteria, neutron activation analysis, artificial caries, scanning electron microscopy, and other methods. 8 …”
