Due to changes in the physical and chemical properties of primary teeth stored in HTB, storage time of not more than 9 weeks is recommended for primary teeth to be stored in artificial saliva in an HTB.
A highly significant decrease in enamel hardness is observed when these teeth are subjected to autoclaving thus increasing their brittleness which does not allow them to be used for their clinical use. Hence further research could throw light on the effects of autoclaving teeth stored for a lesser time in HTB.
Moreover, shade matching is an important criterion which was highly variable before and after sonication. Hence, a longitudinal study on the color stability of HTB stored teeth when used clinically in-vivo is
