 PREVALENCE OF DENTIN HYPERSENSITIVITY

 

Dentin hypersensitivity is a condition that affects a wide spectrum of patients. The statistics below demonstrate the pervasiveness of this common condition. Varying data exist regarding the worldwide occurrence of dentin hypersensitivity. Clinical findings demonstrate, however, that approximately 1 in 5 people in the United States suffer from the condition.² Although sensitivity affects people of all ages, those between the ages of 25 and 50 are more commonly affected,³ and the condition is slightly more prevalent in women.⁴ In the United States, periodontal patients experience sensitivity at very high rates,⁵ and patients undergoing professional tooth whitening also are especially prone to tooth sensitivity. In fact, 55% to 75% of patients suffer from whitening-related sensitivity.⁶

Clearly, dentin hypersensitivity is more prevalent than dental professionals may realize. Data show that 42% of patients do not report consulting their dentist about their condition, and only 27% of those suffering report using a desensitizing dentifrice to help manage the condition.⁷ Instead, many patients modify everyday behaviors to avoid sensitivity, and may not even be aware they are doing so. For example, some patients avoid hot or cold foods or beverages. Others may avoid brushing sensitive areas, placing them at risk for plaque buildup, calculus formation, and even gingivitis.

DIAGNOSING DENTIN HYPERSENSITIVITY

 

Making the proper diagnosis is the first step in assisting your patients suffering from dentin hypersensitivity. Identifying patients who are sufferers can be achieved through close examination of existing conditions and by careful analysis of patient behaviors.

In addition to periodontal patients and those undergoing professional tooth-whitening procedures, other groups at risk for dentin hypersensitivity include those who exhibit gingival recession due to aggressive oral hygiene habits, consumers of high-acid food and drink, patients with parafunctional habits, and patients suffering from xerostomia.

In addition to paying special attention to these circumstances, a comprehensive and thorough examination is necessary to diagnose dentin hypersensitivity. Care must be taken to exclude other conditions such as  dental caries, pulpitis, cracked tooth syndrome, marginal leakage, fractured restoration, and restoration polymerization shrinkage.
