The gingival recession is commonly associated to cervical dentinal hypersensitivity. However, there are no conclusive studies which determine such relationship. The prevalence between these two clinical conditions is usually originated in cervical dentinal hypersensitivity, associated with gingival recession and it justifies the importance of understanding the relationship of these clinical conditions. The objective of this clinical study is to evaluate patients with vestibular gingival recession and the relationship of such condition with the cervical dentin hypersensitivity. Sixtyone patients were submitted to treatment at the Dental Clinic of the UFES School of Dentistry with gingival recession. Subjects were examined in search for the presence of gingival recession and evaluated in order to identify the relationship of each lesion with the cervical dentinal hypersensitivity. Age, gender and teeth type were taken into consideration. The following parameters were recorded through clinical examination: presence or absence of bleeding, visible presence of plaque/biofilm, gingival recession and cervical dentin hypersensitivity. The sensitivity factor (UCHIDA) was applied for sensitivity measurement. The association between the teeth with gingival recession and the presence of cervical dentin hypersensitivity showed statistical significance p<0.001, where the sum of the sensitivity factors were: 69.5% with index 3 in 39.6% of subjects, followed by index 2 featuring 29.9. It was observed, within the studied group, that gingival recession and cervical dentine hypersensitivity are more common on the left side than on the right side of the dentin with arch gingival recession on the left 56.4% (87 teeth) than the right side of 43.6% (67 teeth), bleeding on probing and visible biofilm index were not statistically significant at 5% (p=0.227 and p=0.687). It was concluded that there is a relationship between cervical dentin hypersensitivity and gingival recession.
