The Effect of Cavity Preparation on Substance P Expression in Human Dental Pulp
Journal of Endodontics, 2005Substance P (SP) plays an important role during neurogenic inflammation of dental pulp. The purpose of this study was to use a radioimmunoassay for determining the effect of cavity preparation on SP expression in healthy human dental pulp. Ten pulp samples were obtained from healthy premolars where extraction was indicated for orthodontic reasons. Deep

Adaptation of eight modern dental amalgams to walls of Class I cavity preparations
Journal of Oral Rehabilitation, 1987SummaryAn in vitro study was conducted in which a range of amalgam alloys was condensed into Class I cavity preparations. The force of condensation and increment size were varied to determine the effect of these operator variables on the adaptation, of the alloys investigated, to the prepared cavity walls.

Adaptation of dental amalgam to the cavosurface margin of Class I cavity preparations
Journal of Oral Rehabilitation, 1987SummaryThe adaptation of a range of amalgam alloys to the cavosurface margin of Class I cavity preparations was examined for two condensation techniques. The marginal contour of amalgam condensed into the cavity preparation and packed approximately 1 mm past the cavosurface margin was compared with amalgam margins of restorations which were packed to ...
