Dentin Hypersensitivity(DH) is a commonly occurring condition in majority of population seeking dental treatment. Hence dentist need to pay a special attention for its treatment. Hence the present study aimed to evaluate and compare the desensitizing potential of novamin containing dentifrice and iontophoresis in the treatment of dentinal hypersensitivity. Forty Subjects with age group between 25-55 years with complaint of hypersensitivity to thermal, mechanical, sour stimulus were included in the study. DH was assessed using verbal rating scale. {VRS scores:0 - No discomfort, 1 - Mild discomfort, 2 - Moderate discomfort, 3 - Severe pain only during application of stimulus and 4 - Severe pain persisting after removal of stimulus}. Subjects who showed score of two or more were included. Subject with dental caries, broken teeth, any chronic systemic disease/cardiac pacemakers were excluded. Subjects were divided into Group1 (n-20) Novamin group, Group 2 (n-20) Iontophoresis group. DH was scored before initiating the treatment modalities, immediately after the treatment, one week and one month post operatively. Scores were subjected to Mann-Whitney and Wilcoxon Signed Ranks test. Iontophoresis was more effective in reducing dentinal hypersensitivity than novamin group at week 1. However the difference in mean score between Iontopheresis and Novamin was not statistically significant at Pre-Op and 1 Month. Both Novamin containing dentifrice and iontophoresis can be considered as effective treatment modality in DH.
