Brief Summary

compare the effectiveness of Eggshell derived nano-Hydroxyapatite with and without fluoride and conventional fluoride containing tooth paste versus conventional desensitizing fluoride containing tooth paste on dentinal tubule occlusion and dentin mineral deposition.

Detailed Description

Recently advanced nanotechnology has taken a wide leap in improving the various measures in the treatment of hypersensitivity by its nanoparticles. Nanoparticles can easily penetrate into dentin tubules, which could act as mineralizing agents that block fluid movement within the dentin tubules when combined with various agents.

Hydroxyapatite (HAp) is the major inorganic component of natural teeth and bone. Nano-sized particles of hydroxyapatite are similar to the apatite crystals of tooth enamel in morphology and crystal structure and has been studied as a biomimetic material for the reconstruction of tooth enamel suffering from mineral loss because of its unique potential for remineralization. Nano-hydroxyapatite (n-HAp) was considered a promising active ingredient used for the treatment of DH due to high biocompatibility and bioactivity. In toothpastes, HAp was included in the form of nanocrystals because they dissolve easier in this form. Crystals of n-HAp included in dental products have a dimension of 50-1000 nm, which enables them to act like fillers. These products can penetrate and block the exposed dentinal tubules which are responsible for DH
