In vitro evaluation of a newly produced resin-based endodontic sealer

Abstract

ObjectivesA variety of root canal sealers were recently launched to the market. This study evaluated physicochemical properties, biocompatibility, and sealing ability of a newly launched resin-based sealer (Dia-Proseal, Diadent) compared to the existing root canal sealers (AHplus, Dentsply DeTrey and ADseal, Metabiomed).Materials and MethodsThe physicochemical properties of the tested sealers including pH, solubility, dimensional change, and radiopacity were evaluated. Biocompatibility was measured using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. For microleakage test, single-rooted teeth were instrumented, and obturated with gutta-percha and one of the sealers (n = 10). After immersion in 1% methylene blue solution for 2 weeks, the specimens were split longitudinally. Then, the maximum length of staining was measured. Statistical analysis was performed by one-way analysis of variance followed by Tukey test (p = 0.05).ResultsDia-Proseal showed the highest pH value among the tested sealers (p < 0.05). ADseal showed higher dimensional change compared to AHplus and Dia-Proseal (p < 0.05). The solubility values of AHplus and Dia-Proseal were similar, whereas ADseal had the lowest solubility value (p < 0.05). The flow values of sealer in increasing order were AHplus, DiaProseal, and ADseal (p < 0.05). The radiopacity of AHplus was higher than those of ADseal and Dia-Proseal (p < 0.05). The cell viability of the tested materials was statistically similar throughout the experimental period. There were no significant differences in microleakage values among the tested samples.ConclusionsThe present study indicates that Dia-Proseal has acceptable physicochemical properties, biocompatibility, and sealing ability.

Physicochemical Properties of Epoxy Resin-Based and Bioceramic-Based Root Canal Sealers

“…AH-Plus (Dentsply DeTrey, Konstanz, Germany) is the most popular hydrophobic epoxy resin-based sealer that has been used as the gold standard material [ 3 ]. AD Seal (Meta Biomed, Cheongju, Korea) and Radic-Sealer (KM, Seoul, Korea) are the epoxy resin-based sealers with few reports in literature [ 15 , 16 ].…”

In vitro Study of Different Physicochemical Properties of Root Canal Sealers

“…The increase in the mass of Adseal samples is also supported by the results of the present study. Other researchers also significantly show that Adseal is increasing in weight and volume and has the lowest solubility among the substances they studied [2].…”

“…The ideal root filling must be insoluble, biocompatible, and must remain dimensionally stable after being inserted into the canal. By dimensional change of the sealers we mean shrinkage or expansion of the material after setting, expressed as a percentage [2].…”

Radiopacity of endodontic materials using two models for conversion to millimeters of aluminum

“…It has been reported that the radiopacity of the AH Plus is approximately 7.8 mm Al when measured with the scanner, PSP and digital sensor, 7 9.8 mm Al, with the scanner, 4 10.41 mm Al, with the CCD digital sensor 26 and 14 mm Al, with the photodensitometer. 27 The divergent information on AH Plus radiopacity 4,7,27 could be attributed to the use of different devices used and methodologies applied.…”
