Abstract

Background: Tooth sensitivity or dentin hypersensitivity is a common oral issue that is easily diagnosed but difficult to treat thoroughly. Currently, there have been many methods to treat dentin hypersensitivity, in which using low-level laser therapy is a new method with many advantages and needs to be studied more. Objectives: This study aims to determine clinical features, relative risk factors and evaluate the treatment effectiveness of low-level laser therapy for patients with tooth sensitivity on premolar and molar teeth. Materials and methods: A sample 101 patients >= 18 years old with 236 premolars and molars were divided into 2 treatment groups (n=118 each): group I (810nm diode laser, 0.5W) and group II (GC Tooth Mousse cream) from January 2021 to June 2022 at Can Tho University of Medicine and Pharmacy Hospital, sensitivity was assessed by evaporative stimulus. Results: The mean age was 33.35±13.5 years old. The prevalence of female was 57.4%, male was 42.6%, most sensitive position was in the cervical (98.3%), the most common triggering factor for tooth sensitivity was cold stimulation (88.1%), horizontal brushing (81.2%) was the main risk factor associated with tooth sensitivity. In both groups, there were effective reductions in tooth sensitivity at the immediate time and 3 months after treatment (p<0.001). There was no statistically significant difference in the effectiveness of reducing tooth sensitivity of group I and group II at 3 months after treatment (VAS score: 2.72± 2.31 and 3± 2.1, p=0.14). The treatment success rate of group I was 70.4% immediately and 78% after 3 months. Conclusion: Adults who have a habit of brushing their teeth horizontally are more prone to tooth sensitivity, especially in the cervical. Low-level laser therapy (810nm, 0.5W) effectively reduces tooth sensitivity immediately and after 3 months.
