- Abstract
Background and purpose: Dentin hypersensitivity (DH) is a sharp, short dental pain which originates from exposed dentin surfaces in response to thermal, evaporative, tactile, osmotic, chemical or electrical stimuli. Research showed that dentin tubule occlusion can lead to pain remission. Our goal was to evaluate the dentinal tubules in the cervical area of root teeth that are occluded by fluoride varnish, diode laser irradiation, and erbium laser irradiation. Materials and methods: This is an in vitro single-blind study. Twenty-four samples of extracted third molars were divided into four groups: control (A), fluoride varnish (B), fluoride varnish and diode laser (C) and fluoride varnish and Er,Cr:YSGG laser (D). After applying varnish and different lasers, the tubule diameter and number of open tubules were examined by SEM. Data were analyzed by SPSS 23 software. Results: In this research, there was no significant difference between groups C and D (ρ=0.999), although there were substantially more open tubules in the control group than groups C (ρ=0.004) and D (ρ=0.003). The mean diameter of tubules in the four groups was statistically different (ρ <0.001), and the descending order of tubule diameter was A > B > C > D. Conclusion: Using diode and erbium laser in combination with sodium fluoride varnish had a significant effect on the reduction of dentinal tubule diameter and their occlusion; thus, these therapies can be used to treat dentin hypersensitivity.
