Stain of four composite by the phytotherapic Punica granatum L.

The Punica granatum Linn (pomegranate), which is used in popular medicine, is considered to have good antibiotic and anti-inflammatory properties. It seems to have a control effect as a mouthrinse, although, until now, there has been no report on its staining when in contact with resin-based composites.

Objectives: To evaluate the stain of 4 resin-based composites (Estheth-X A1, Estheth-X YE, TPH, and Quixfil [Dentsply – Brasil]), with pomegranate extract, in 5 different time periods (24 hrs, 7, 14, 21, and 28 days).

Methods: The analysis was carried out spectrophotometrically We recorded reflectance and transmittance measurements in the wavelength band of the visible spectra (380-760 nm). The geometry used for the reading had an 8-degree angle of incidence, and the device was calibrated (D65) before and after the stain measurement (according to ISO 7491).

Results: ANOVA analysis among the different groups showed that the stain of the pomegranate extract was significant in all experimental time periods for all 4 resin-based composites. The Esthet-X YE presented the greatest stain, followed by Quixfil, Esthet-X A1, and THP.

Conclusions: This phytotherapic, in extract form, can interfere with resin-based color (supported by CAPES).
