Discussion

Pre-clinical study reveals enhanced bone regeneration with PDLSCs and biphasic scaffold, suggesting improved osseointegration.

PDLSC + scaffold group showed significantly higher bone volume/total volume compared to control and scaffold groups.
Bone-to-implant contact and new bone formation were notably increased in the PDLSC + scaffold group with values of 68.2% and 75.6%, respectively.
Histological analysis confirmed robust new bone formation and intimate integration in the PDLSC + scaffold group versus control and scaffold groups.
Implanting PDLSCs with a scaffold may enhance therapeutic strategies for bone restoration around dental implants.

Parihar et al. (2025) studied this question.
