Abstract

Background: Research on the effects of Diode laser and Er,Cr:YSGG laser in the treatment of dentin hypersensitivity is still limited. Objectives: Describing the clinical characteristics and comparison of treatment outcomes for dentin hypersensitivity using Diode laser and Er,Cr:YSGG laser. Materials and methods: We conducted a randomized controlled clinical intervention study on 36 patients with 89 teeth affected by dentin hypersensitivity, who sought examination and treatment at the Department of Dentistry, Can Tho University of Medicine and Pharmacy Hospital from June 2023 to March 2024. Results: The majority of patients were over 46 years old, accounting for 55.5%, with male comprising 63.8%. Most sensitive teeth were incisors (48.5%) and premolars (31.4%), with the most common cause being gingival recession (57.4%). Most patients exhibited moderate to severe dentin hypersensitivity. All patients achieved good to very good treatment outcomes, with those treated with Er,Cr:YSGG laser showing significantly better improvement in dentin hypersensitivity compared to the Diode laser group at 30 minutes and 1 month post-treatment. At the three-month post-treatment mark, most patients no longer experienced dentin hypersensitivity. Conclusion: Patients treated with Er,Cr:YSGG laser showing better improvement in dentin hypersensitivity compared to the Diode laser group. At the three-month post-treatment mark, most patients no longer experienced dentin hypersensitivity.
