FTIR spectroscopy and microhardness measurements were employed to follow the degree of curing of visible light activated dental composites. The observed dependence of curing on grade and shade of the materials, exposure time and depth from the light exposed surface have been discussed. Immediately after curing, it was found that direct correlation of microhardness values with that of double bond conversion estimated by FTIR technique could not be established.

Steam sterilization is conventionally used for the sterilization of materials used in surgery and medicine. When subjected to repeated steam sterilization, oligomers of polyethylene terephthalate are produced on the surface of the polyester materials. The consequences of the production of such oligomers on the biocompatibility of the polyester material have been investigated. Growth inhibition of L929 fibroblast cells has been observed on the repeatedly sterilized materials in the
