    Effect of Pal of filler particles on the physical properties of a dental composite
    (INDIAN JOURNAL OF ENGINEERING AND MATERIALS SCIENCES, 1998) Manu, S; Usha, K; Jyothi, S; Krishnan, VK; Pal, SN
    Use of silane treated fillers in chemical curing Bisphenol A-Glycidyl methacrylate (Bis-GMA) based dental composites has been found to improve the properties appreciably. The nature and concentration of the silane used is found to be critical in deciding the final properties. However, water sorption does not seem to be, considerably affected by varying silane concentration. Morphology of the fractured surface indicates that composites containing 3-(trimethoxysilyl) propyl methacrylate (TSPM) treated fillers provide, better filler-matrix compatibility resulting in better strength characteristics.

    Effect of tertiary amine accelerators on the physical properties of visible light cured dental composites
    (JOURNAL OF POLYMER MATERIALS, 1996) Manu, S; Krishnan, VK; Pal, SN
    The effect of changing the tertiary amine accelerator on the physical properties of visible light cured dental composites is described in this paper. Three aromatic and two aliphatic tertiary amines were used in this study. The diametral tensile strength and Vickers microhardness of the cured specimens were determined. The presence of highly active aromatic amines like dimethyl p-toluidine (DMPT) and dimethyl amino phenethyl alcohol (DMAPEA) gave better properties for the cured composite compared to diethanol p-toluidine (DEFT).
