Comparison of stem cells from human exfoliated deciduous posterior teeth with varying levels of root resorption.

Background: Stem cells from human exfoliated deciduous teeth (SHED) are regarded as an attractive cell source for tissue regeneration. However, the effect of different levels of root resorption on the characteristics of SHED remains less understood. Thus, the tooth source that is most suitable for the isolation of SHEDs needs to be determined.

Characterization of Stem Cells from Human Exfoliated Deciduous Anterior Teeth with Varying Levels of Root Resorption.

Background: Deciduous teeth undergo the physiologic process of resorption, during which the remnant pulp undergoes activation. However, the quality of stem cells obtained at various stages of root resorption has not been documented.

Objective: To isolate and characterize stem cells from deciduous teeth with varying levels of root resorption.
