Abstract

Objective: Describe the characteristics of dentin hypersensitive teeth in patients at the Department of Dentistry - Ha Dong General Hospital in 2023 - 2024. Research methodology: Cross-sectional descriptive study on 3351 teeth in 120 patients at the Department of Odontology, Ha Dong General Hospital, collecting data based on clinical examination forms. Results: The rate of dentin hypersensitivity was 12.5%. The premolars had the highest rate of dentin hypersensitivity (45.7%), followed by the anteriors and the molars with rates of 28.2% and 26.1%, respectively. Teeth with cervical wear, occlusal wear and gingival retraction had dentin sensitivity rates of 55.5%, 33.5% and 49.4%, respectively. The rate of dentin sensitivity increased in the groups with cervical erosion level 1, level 2, level 3, respectively, at 48.4%, 58.3% and 49.6%. The groups of teeth with occlusal abrasion of grade 1, grade 2, grade 3 had dentin hypersensitivity rates of 45.4%, 35.4% and 27.9% respectively. The dentin hypersensitivity rates in the gingival retraction groups of 1 mm, 2 mm, 3 mm were 50%, 52.9%, 38.5% respectively. Conclusion: Premolars were the group of teeth with the highest dentin hypersensitivity rate. Cervical erosion was a frequent cause of dentin hypersensitivity. The level of enamel wear and dentin exposure had a higher rate of dentin hypersensitivity than dentin wear
