SDI’s Tints and Masking Agents simulate a life like, natural tooth. The natural tooth color is derived from the color saturated dentin in conjunction with light penetrating the translucent enamel and undergoing reflection, transmission and absorption. The SDI Shade Modification system simply and quickly achieves optimum esthetics with paint on, single component, light cured liquid Tints and Masking Agents.

Low Viscosity

The ideal low viscosity allows for quick, easy and direct paint on application. The low viscosity resin eliminates the appearance of brush strokes and micron thin layers permit fine veneers.

Direct Application

The SDI Shade Modification system’s syringe and bent tip delivery system facilitates controlled direct extrusion for faster procedures.

Masking Agents

SDI Masking Agents hide enamel anomalies and discolorations to achieve natural looking restorations.

Multiple Uses

Nine Tints and four Masking Agents ensure life like restorations are possible for even the most difficult restorative situations.

Tooth Shades

The selection of the appropriate Masking Agent, Tint and restorative material is  controlled by the multichromatic nature of the tooth which consists of four color zones:
1. Cervical zone – Red, Yellow, Orange or Brown
2. Body zone – Grey, Yellow, Universal
3. Interproximal zone – Differing between patients
4. Incisal zone – Grey, Blue
Darker colors in gingival areas become lighter towards the incisal edge.
