Efficacy of NovaMin- and Pro-Argin-containing desensitizing dentifrices on occlusion of dentinal tubules

Dentin hypersensitivity is a commonly occurring condition characterized by short, sharp pain arising from the exposed dentine in response to stimuli.
Seventy extracted human permanent molars were selected and divided into four groups. The photomicrographs of the surface from the center of each dentinal block were obtained using a scanning electron microscope. The objective of this study was to evaluate the ability of three desensitizing dentifrices − SHY-NM (NovaMin), Sensitive Pro-Relief (8% arginine and calcium carbonate) and Thermoseal (10% strontium chloride) − for dentinal tubule occlusion using a scanning electron microscope.
All of the desensitizing dentifrices evaluated, SHY-NM showed the highest percentage of tubular occlusion (95.58%) followed by Sensitive Pro-Relief (89.90%). The least amount of tubular occlusion was shown by Thermoseal (86.12%).
NovaMin-containing toothpaste, SHY-NM, showed maximum tubular occlusion and it appears to be a promising desensitizing dentifrice.
