| Abstract | ||||
| Background: Dentin Hypersensitivity is a common dental problem affecting a huge section of every population that doesn’t have a permanent treatment yet. Aim: The purpose of this study is to compare the effect of Diode laser (940nm) and Nano-desensitizing agent on the degree of tubular occlusion compared to the conventional fluoride varnish for the treatment of dentin hypersensitivity. Materials and methods: Twenty dentin specimens were prepared from extracted human premolars. Dentin specimens will be randomly allocated in 4 groups (n=5) according to desensitizing agent used: D1 (Diode Laser (940nm), D2 (Nano-hydroxyapatite), D3 (Diode Laser + Nano-hydroxyapatite) and D4 (Fluoride). The specimens will be treated with EDTA for 2 mins to open dentinal tubules simulating Dentin Hypersensitivity. Each specimen will be evaluated at 3 different times: T0 (before material application), T1 (after material application) and T2 (after acid attack) using Environmental Scanning Electron Microscope and Image Analysis software to detect degree of occlusion of dentinal tubules. Results: Group D3 showed statistically significant tubular occlusion percentage compared to group D1 and there was no statistically significant difference between other groups. After acid attack group D3 were the only group that showed non-statistically significant decrease in tubular occlusion percentage denoting the best resistance to acid attack, while other groups were drastically affected by the acid attack. Conclusion: Combining DL (940nm) and Nano-hydroxyapatite could be a successful treatment option for Dentin Hypersensitivity, due to its high degree of tubular occlusion effect and sustainability in the acidic environment.
