Dentin hypersensitivity: Etiology, prevalence and treatment modalities

Dentin hypersensitivity is a very common clinical symptom, which consists of sharp pain arising from exposed dentin in response to various types of stimuli and thus can cause considerable concern for patients. This condition is frequently encountered by periodontists, dentists and hygienists. The management of this condition requires good understanding of the complexity of the problem, as well as knowledge of the variety of treatment options available. Clinical trials on dentin hypersensitivity have been numerous and protocols varied. However, the entire body of clinical research literature is far from being unequivocal in suggesting one superior strategy. This paper reviews the etiology, prevalence and treatment modalities of dentinal hypersensitivity and describes a new approach to in-office treatment of dentin hypersensitivity using new biocompatible materials. Future treatment modalities for dentin hypersensitivity are currently under development that might combine the benefits of being both non-invasive and permanent, yet cost effective for both dentist and patients.
