Abstract

Objectives: To evaluate clinical characteristics of dentin hypersensitivity (DH) after tartar removal on Vietnam Military Medical University students at Military Hospital 103. Methods: A prospective, cross-sectional descriptive study on 96 students with 183 teeth diagnosed with DH. The research subjects are long-term military medical students from the 2^nd to 4^th year who came to the Department of Oral Surgery (B14), Military Hospital 103, from February to June 2023. Evaluation of the characteristics of sensitive stimulation, sensitive location, sensitive tooth group, sensitive cause, and degree of dentin sensitivity was done with the Yeaple probe. Results: The mean age was 22 ± 1.18, male/female ratio = 92/4. Cold stimulation was the patients' most common type of dentin sensitizer (81.3%). The group of dentin-sensitive teeth from 1 - 2 teeth accounted for the majority, with 82/96 patients accounting for 85.4%. The dentin hypersensitivity after tartar removal was most common in the incisors group, accounting for 53.6% and the neck position (77.6%). The most common cause of dentin hypersensitivity in the studied teeth was tooth abrasion, accounting for 27.3% and up to 43.7% of dentin hypersensitivity of unknown cause. According to the Yeaple score, the average dentin sensitivity was 38.75 ± 10.94g, mainly moderate and mild in the study group. Conclusion: After tartar removal, dentin hypersensitivity is usually caused by cold stimulation, usually in the incisors group, in the cervical region, and most of the patients have moderate and mild dentin hypersensitivity.
