Evaluation of the Clinical Efficacy of a new Desensitizing Tooth Paste Containing Nano-crystalline Hydorxyapatite in Dentine Hypersensitivity Patients : A Double Blind Randomized Controlled Clinical Trial

Aim: Several dentifrices have been shown to be effective in reducing dentine hypersensitivity ® (DH). The aim of the present study was to evaluate the desensitizing efficacy of Aclaim toothpaste. Materials and Method: A double blind randomized controlled clinical trial was performed on 40 ® subjects in which 20 were asked to use Aclaim toothpaste (test group) and 20 were asked to use fluoridated foaming dentifrice available in market . All subjects were examined at baseline and after 3 weeks and 6 weeks; at each visit only the teeth identified as hypersensitive at baseline were re-evaluated. The hypersensitive teeth were assessed using the commonly used and validated stimuli tests: tactile tests, air blast test and ice stick test and subjective tests. Results: The results showed that both dentifrices were largely effective; the mean score reduction from baseline to 6 weeks was significant in all the parameters (air blast, tactile, ice stick and subjective test) in both the groups. But, the test group showed a statistically significant mean score reduction in all the parameters recorded. Conclusion: The results of the present study suggested that there is a significant reduction in
