Dentine sensitivity risk factors: A case–control study

Abstract

Objective:To identify the clinical and psychological risk factors associated with dentine hypersensitivity (DH) in order to provide an early diagnosis and preventive therapy.Materials and Methods:A nested case–control study was design between 2011 and 2012. A total of 61 DH cases and 122 controls participated in this investigation. Cases and controls were matched for sex, group of age and socioeconomic status in a ratio of 1:2. DH to different stimuli such as cold, heat, acid, and sweet was asked in patient interviews, and dental examinations were used to detect DH. Clinical and psychological risk factors such as dental hygiene, periodontal disease, acid diet, alcohol consumption, psychological stress, and psychopathological symptoms were inquired. Psychological stress was measured through the PSS-10 and psychopathological symptoms were evaluated by SCL-90-R in Spanish. Descriptive and univariate binary logistic regression analysis were performed to estimate the association between clinical and psychological risk factors and the presence of DH.Results:Toothpaste abrasivity (odds ratio [OR] 1.881, 95% confidence interval [CI] 1.010–3.502, P = 0.045), gingival recession (OR 2.196, 95% CI 1.020–4.728, P = 0.041), and periodontal therapy (OR 5.357, 95% CI 2.051–13.993, P < 0.001) were associated with DH. Subjects with perceived stress (OR 1.211, 95%, CI 0.518–2.833, P = 0.658), obsessive-compulsive (OR 1.266, 95%, CI 0.494–3.240, P = 0.623) and hostility (OR 1.235, 95%, CI 0.507–3.007, P = 0.642) symptoms had a clinical greater odd of DH.Conclusion:Oral hygiene products and periodontal conditions are important risk factors for DH. Individuals with perceived stress, obsessive-compulsive, and hostility symptoms may increase a clinical risk for this entity. Targeting to dental counseling focused on oral hygiene products, periodontal therapy and a psychological evaluation may be promising in DH prevention.

“…2,3 More worrisome is that the excessive demineralization of the tooth surface due to erosion has been reported to initiate the onset of dentine hypersensitivity (DH). [4][5][6] According to the Canadian Advisory Board on DH, 7 DH is characterized by distinctive short, sharp pain arising from exposed dentinal tubules particularly in response to external stimuli that are typically thermal, evaporative, tactile, electrical, osmotic, or chemical changes which cannot be ascribed to any other form of dental defects or pathology. As reported in the literature, DH is one of the most clinically encountered problems in dentistry affecting between 10 to 30% of people worldwide.…”

Dentine Hypersensitivity and Its Associated Factors: A Cross-Sectional Study Conducted on Patients Visiting Dental Hospital of Karachi, Pakistan

“…1 It can be defined as a sharp pain of short duration initiating from dentine which occurs when exposed to the external stimuli such as heat, cold, touch or chemical. 2 The occurrence of dentine hypersensitivity increases from 30-40 years of age. Additionally, females are more commonly affected as compare to males.…”

The relationship between dentine hypersensitivity, dietary acid intake and erosive tooth wear

“…Dentine tubules must be patent for dentine hypersensitivity to occur [2] and it has been observed in vitro that dietary acids can remove the smear layer exposing dentinal tubules [3]. Dietary acid intake has been associated with dentine hypersensitivity [1,4,5], with one clinical trial reporting a relationship between dietary acid intake in the previous hour and a positive response to clinical dentine hypersensitivity testing [6].…”
