ContextDentinal hypersensitivity (DH) is a commonly encountered problem. Several products are used in management of DH with varying results. Need is felt in dentistry for a material that chemically reacts, physically occludes and adheres intimately to dentinal tubules to reduce the possibility of its recurrence. One such material is calcium sodium phosphosilicate-Novamin.AimTo evaluate an efficacy of a 5% calcium sodium phosphosilicate (Novamin SHY NM) containing dentifrice compared to placebo for the relief of DH.Settings And DesignOutpatients visiting Dept of Periodontics, Yenepoya Dental College with DH were deemed eligible for this case-control clinical trial after an informed consent.Materials And Methods30 patients having at least 2 sensitive teeth with a VAS (Visual Analogue Scale) of >3 cm after air blast stimulation, qualified to participate in the study. Test (SHY NM toothpaste containing 5% calcium sodium phosphosilicate) and control (Pepsodent toothpaste without a desensitizing agent) groups, each containing 15 participants, were subjected to cold water and air blast stimulation for an assessment of DH at baseline, 6 th and 8 th week using VAS.Statistical Analysis UsedUnpaired t-test and repeated measures ANOVA.Results5% Novamin containing dentifrice significantly reduced DH within 6 th and 8 th week of usage when compared to a placebo dentifrice.ConclusionsA Novamin containing dentifrice significantly reduced DH when compared to a placebo dentifrice.
