Abstract : Introduction Due to harmful lifestyles and unhealthy diets, the number of adults with dentin hypersensitivity (DH) is increasing. DH is defined as sharp pain arising from exposed dentin in response stimulant. This study aimed to assess the prevalence of DH, the relative importance of risk factors, patient habits, and oral health behaviors, and the role of dental practices in DH. Methods In the outpatient department of Khamis Mushait General Hospital in Saudi Arabia, a cross-sectional analytical study using a questionnaire and a clinical examination was conducted using systematic random sampling. 220 eligible participants agreed to participate and provided written informed consent. They were interviewed and then underwent clinical examinations to identify those with DH. The second examination was performed to exclude confounders. The outcome variable “Dentin hypersensitivity” was assessed with both the Schiff scale and air blast tolerance evaluations to determine the outcome, and sensitivity parameters were measured. Results There were 220 participants with 55% males and 45% females. The mean age was 39 years of age. The crude prevalence of DH was 38.5%, and after excluding other factors, it was 15% for sound teeth. According to the Schiff scale, 3.2% had a score of 3, 14.1% had a score of 2, 10.9% had a score of 1, and 71.8% had a score of 0. The most common hard tissue factors associated with DH were dental caries (12%), fractured restorations (10%), and sound restorations (10%), while the most common soft tissue factor was gingival recession (11.4%). The most frequent medical conditions were heartburn (28%) and one chronic disease (22%). According to stepwise regression, there was a significant association between DH and gingival recession (P < 0.05) and between DH and sound restorations (P < 0.05). Conclusions The crude prevalence of DH was 38% in total, but only 15% after hard tissue factors were excluded. This demonstrates the importance of clinical examinations to obtain the best estimation of prevalence. This study also shows that gingival and periodontal health is important for the prevention of DH.
