A case-control study was conducted to determine some risk factors associated with the dentin hypersensitivity in patients with dental prosthesis that attended the Oral Maxillofacial Rehabilitation Clinic of Santiago de Cuba from May 2009 to December 2010. Patients were divided into 2 groups: one of 60 patients (cases) and another of 120 (control) with ages ranging from 20 to 61 years. Chi square test was applied with 95% confidence, and basic association was determined between variables by calculating the odds ratio, whose predominant results were recession of the gums (3.62), erosion (3.20) and incorrect brushing (2.56); the first 2 variables also constituted the main risk factors in the study population (attributable risks of 2.62 and 2.20% respectively). Also, the need to instruct patients in the elements that favor the onset of this oral condition and the way to remove them was evaluated.
