Abstract

Clinical Evaluation of a Dentifrice Containing Nhap for the Reduction of Dentin Hypersensitivity

Highlights

The percent reduction in sensitivity at 4 weeks for the test group was 69.6% for Sensitive White and 66.7% for Sensitive Ultra. These results demonstrate that the nHAP-containing dentifrices were effective at reducing sensitivity
Dentin hypersensitivity (DH) has been defined as a “short, sharp pain arising from exposed dentin in response to stimuli, typically thermal, evaporative, tactile, osmotic or chemical, and that cannot be ascribed to any other form of dental defect or pathology” [1]
A wide range of estimates of prevalence of dentine hypersensitivity was observed in 56 studies, from as low as 1.8% to as high as 84%, and this heterogeneity could not be completely explained by study characteristics

Summary

Introduction

Dentin hypersensitivity (DH) has been defined as a “short, sharp pain arising from exposed dentin in response to stimuli, typically thermal, evaporative, tactile, osmotic or chemical, and that cannot be ascribed to any other form of dental defect or pathology” [1]. Dentine hypersensitivity is a significant burden for patients and practitioners. A wide range of estimates of prevalence of dentine hypersensitivity was observed in 56 studies, from as low as 1.8% to as high as 84%, and this heterogeneity could not be completely explained by study characteristics. One of the most frequent patient complaints is related to cold stimuli, pain may occur when consuming acidic foods (mainly fruit), sweets and salty foods. Tactile stimulus provocation frequently occurs when patients brush their teeth or rub the sensitive area with a finger nail [4]. The most accepted one is Brannstrom’s hydrodynamic theory [5]. According to this theory, DH is caused by shifts in the fluid located inside the open dentin tubules.
