Development, characterization and comparison of two strontium doped nano hydroxyapatite molecules for enamel repair/regeneration

Highlights • Newly developed Sr doped nHAp particles for a better choice for treating white spot lesions and incipient carious lesions. • Sr doped nHAp showed increased agglomeration and cluster formation. • 25% Sr-nHAp is found to be of better choice considering the diffusion and crystallinity it e...

Description
Summary:Highlights • Newly developed Sr doped nHAp particles for a better choice for treating white spot lesions and incipient carious lesions. • Sr doped nHAp showed increased agglomeration and cluster formation. • 25% Sr-nHAp is found to be of better choice considering the diffusion and crystallinity it exhibits. • Sr doped specimens showed less cytotoxic effects compared to pure nHAp. • Complete obliteration of pores was evident with Sr doped materials comparison to the currently used ACP-CPP and nHAP based dentifrices.
