Abstract:
BACKGROUND:NovaMin is a kind of bioactive glass, and its active ingredients react with saliva to form hydroxyapatite crystals, which deposit on the surface of the teeth and can close the exposed dentinal tubules. It can be used for the treatment of dentin hypersensitivity.
OBJECTIVE:To study the effect of toothpaste containing NovaMin on tooth hypersensitivity patients after subgingival scaling and root planing surgery.
METHODS:According to inclusion and exclusion criteria, 96 patients were picked out from 543 patients to participate in the experiment. In compliance with the principle of randomized, double-blind, comparison, 98 subjects were randomly divided into two groups:experiment group in which the toothpaste containing NovaMin was used, and control group in which the toothpaste without NovaMin was used. Visual analog scale scoring was used to evaluate the degree of sensitivity to air stimulus respectively before and 4 weeks after al ergy experiment.
RESULTS AND CONCLUSION:Total y 88 patients completed the experiment. After treatment with toothpaste for 4 weeks, visual analog scale scores in the experiment group decreased from 4.25±1.87 at baseline to 2.53±1.22 by air stimulus, and visual analog scale scores in the control group decreased from 4.03±1.92 at baseline to 3.63±1.45. The visual analog scale scores in the experiment group and control group both reduced, and the difference was with statistics significance (P<0.05). Compared with the control group, visual analog scale scores in the experiment group decreased more significantly. It showed that the toothpaste containing NovaMin has significant effect on dentin hypersensitivity after subgingival scaling and root planing surgery.
