Updates on Effect of Radiopacifier in Portland Cement for Repairing Furcal Perforations
The Effect of Radiopacifier in Portland Cement for Repairing Furcal Perforations
This study was designed to evaluater adiopacity, interface micrographs, and leakage mediated by zirconium oxide (ZO) placed into white Portland cement (PC) as a furcal perforation sealing material. Perforations were created in the floors of pulp chambers in 56 freshly human maxillary and mandibular molars and randomly divided into four experimental groups, each containing 12 teeth, and a negative control group containing 8 teeth. The experimental groups were prepared using 20% ZO plus PC, PC, ProRoot mineral trioxide aggregate (MTA), and 20% bismuth oxideplus PC. First, radiopacity was assessed through X-ray. Second, the concentration of leaked glucose was measured at day 1, 2, 4, 7, 10, 15, and 21 using a glucose oxidase method. Third, using scanning electron microscopy (SEM), we showed the interface between each material and teeth. The data were evaluated using the Kruskal-Wallis test. The results suggest that three materials showed sufficient radiopacity, the only exception is the lower radiopacity of PC, and ZO could be considered as an alternative radiopacifier to be added in PC, without changing the ability of sealing the furcal perforations.
This study showed that the sealing ability promoted by all 4 materials was similar. ZO could be considered as an alternative radiopacifier to be added in PC, without changing the sealing ability at the furcal perforations. However, further research is needed to evaluate the behaviors of the radiopacifying agents associated with PC with respect to other physicochemical and biological properties and clinical applications of this type of materials.
