Abstract

Objective: To describe the clinical characteristics of dentin hypersensitivity in patients treated for cervical dentin hypersensitivity at School of Dentistry, Hanoi Medical University. Subjects and Methods: A cross-sectional descriptive study was conducted on 124 teeth in 30 patients with cervical dentin hypersensitivity treated at School of Dentistry, Hanoi Medical University, from July 2024 to April 2025. Data were collected through questionnaires and clinical examinations, and processed using SPSS 20 software. Results: There was no significant difference in dentin hypersensitivity distribution among the three age groups. The proportion of female patients (70%) was higher than male patients (30%). Molars had the highest rate of dentin hypersensitivity (46.77%), followed by premolars (27.42%) and anterior teeth (25.81%). The main causes of hypersensitivity in molars and premolars were abrasion and abfraction lesions respectively. Gingival recession and a combination of factors were the primary causes in anterior teeth. Cold stimuli were the most common trigger for hypersensitivity symptoms (56.67%). Most teeth exhibited moderate sensitivity to air stimulus based on the VAS scale (67.7%) and tactile stimulus measured with the Yeaple electronic probe (57.3%). Conclusion: Molars showed the highest prevalence of dentin hypersensitivity. Cervical abrasion was the most common cause. Cold was the most frequent triggering factor. Teeth with moderate dentin hypersensitivity accounted for the highest proportion.
