Pearl is a self-cured, filled permanent cement designed for cementing conventional cast restorations on most vital and non-vital teeth. It also cements bonded bridges of both cast and etched (Maryland) and perforated base (Rochette) types. It is also suitable for cementing prefabricated laminate veneers, ceramic crowns, inlays, onlays, pins, posts and periodontal splinting. Auto-mix system. Versatile. Predictable, controllable and reproducible working time. Excellent biological and chemical resistance to oral environment. Excellent adhesion to both the tooth and metal surfaces. High compressive and diametral tensile strength. Simplicity in application. Physical Data: Compressive Strength-215 MPa, Diametral Tensile Strength-42 MPa.
