TPH Spectra LV Compules. TPH Spectra is the only composite that is available with both a Low Viscosity (Creamy) and High Viscosity (Sculptable & Packable) handling option to meet the preference of both the clinical indication and the clinician. The chameleon effect of TPH Spectra means it has a simplified shading system, and TPH Spectra also provides stain resistance and has high radiopacity. UOM: 20/pk.
