Abstract
Objectives: To evaluate the efficiency and stability of Nano seashell, Sodium Fluoride and Signal Complete 8 in treatment of dentine hypersensitivity.
Methods: Forty freshly extracted premolar teeth were collected, disinfected, and sliced into 1.0± 0.1mm thickness. The dentin discs were randomly divided into two main groups of 20 discs each. Group 1(n=20): Dentin discs subjected to treatment not followed by acid challenge. Group 2 (n=20): Dentin discs subjected to treatment followed by acid challenge. Each group was further subdivided into 4 subgroups of 5 discs each according to the treatment used; Subgroup A (Control group): discs received no treatment; Subgroup B: discs treated with Sodium Fluoride paste; Subgroup C: discs treated with Nano Seashell paste; Subgroup D: discs treated with Signal Complete 8 toothpaste. Evaluation of dentinal tubules obliteration was done under scanning electron microscope.
Results: There was a significant change in the diameter of tubules and percentage of occlusion for group 1. Group 2 (subjected to acid challenge after treatment) has shown high stability for subgroup B (Sodium Fluoride), followed by subgroup D (Signal Complete 8) then subgroup C (Nano seashell paste).
Conclusion: Nano seashell and Sodium Fluoride caused significant increase of occluded dentinal tubules than Signal complete 8 but the mineral deposits formed by Sodium Fluoride showed higher resistance to acidic environment than those formed by Nano seashell.
