After the development of a two-paste chemical cure composite, evaluation of its physicochemical properties, toxicological evaluation and in-vivo experiments in dogs teeth with histopathological study of dental tissues, a clinical trial was carried out and commercial production recommended. As the shelf life of the material was not enough, a light cure composite was developed, its material characteristics, toxiclological study, in-vivo experiments in dogs with histopathological evaluation and clinical trials carried out. However, the material was radiolucent, and could not be seen in an x-ray and differentiated from a cavity after filling was done. This led to the development of radiopaque light cure composite. Compressive strength, diametral strength, and microhardness were tested with 200-250 phr range of incorporated radiopaque glass particle filler of the size 0.7 to 1.0 μm. this improved the properties when compared to conventional composites. The composite was non-toxic and suitable for animal studies. In vivo studies are underway in dogs with histopathological studied of the pulp and dentin. The material awaits clinical trials prior to commercial production.
