27 patients who reported dentin hypersensitivity were randomly selected. (dentaladvisor.com)
Dentin hypersensitivity and gingival recession: Breaking the cycle. (colgateprofessional.com)
Gingival recession is a strong risk factor for dentin hypersensitivity. (colgateprofessional.com)
While gingival recession does not cause dentin hypersensitivity, the loss of gingival tissue predisposes a patient to hypersensitivity and often occurs alongside it . (colgateprofessional.com)
However, dentin exposure leaves these plugs and the smear layer vulnerable to removal, at which point the patient may start to experience dentin hypersensitivity. (colgateprofessional.com)
Inadequate biofilm control can in turn cause the advancement of periodontal disease and gingival tissue loss, which can then increase the risk or severity of dentin hypersensitivity. (colgateprofessional.com)
In order to reduce the burden of both gingival recession and dentin hypersensitivity, dental professionals must implement prevention and management strategies in five key areas. (colgateprofessional.com)
The prevalence of dentin hypersensitivity is estimated to be as high as up to 85%, but the number of patients actually reporting symptoms to you will no doubt be significantly lower. (colgateprofessional.com)
Despite the negative impact on their wellbeing and quality of life, many patients view dentin hypersensitivity as an unavoidable fact of life, rather than a treatable condition. (colgateprofessional.com)
For those reasons, it is important that dental professionals proactively incorporate dentin hypersensitivity screening into their routine oral health care. (colgateprofessional.com)
