In vitro evaluation of dentinal tubule occlusion by novamin (bioactive glass)
Aim–The aim of this study was to evaluate the dentinal tubule occluding ability of Novamin (bioactive glass) containing desensitizing dentifrices using scanning electron microscope. Materials and Methods – Forty-five 1mm thick dentine discs were obtained from orthodontically extracted human premolar teeth. Each disc was then split into two halves producing a total of 90 dentine specimens. One half of each disc was allotted to Group -1(Control group) and the other half was allotted to group-2 (Test group). GROUP 1: brushed without dentifrices.
