Background:
Dentin hypersensitivity is the most prevalent condition among several factors which cause the patients discomfort and make them visit dental office frequently. Novamin and proargin are the newer technologies which are proposed to have a better sensitivity reduction efficacy. The main objective of this study was to compare the efficacy of commercially available desensitizing toothpastes containing Novamin and Pro-Argin in reducing dentin hypersensitivity. Materials and methods: This is a double blind trial in which simple randomization by using coin toss method was done.A total of 50 patients with a chief complaint of sensitivity of at least one tooth due to gingival recession were included in the study. Examination was carried out using tactile stimulation, air-blast stimulation and cold water stimulation at baseline. Each patient was then provided one of the test dentifrices and were instructed to massage gently with the dentifrice for 5 mins and then brush the teeth in the usual manner with a soft bristled toothbrush for 2 min, twice daily. Patients were recalled at 2 weeks, 4 weeks and 6 weeks and examinations were carried out. Statistical analysis used: Repeated measure analysis of variance, unpaired t test, post hoc analysis
Results: On comparing the efficacy of product A and B using all the 3 measurements, product A (VANTEJTM) showed greater reduction of sensitivity than product B (COLGATE SENSITIVE PRORELIEFTM), but statistically significant differences were observed only with cold water stimulation test.
Conclusion: Desensitizing toothpaste containing Novamin showed better reduction of sensitivity when compared to dentifrice containing Proargin technology.
