[Research progress and application prospect of stem cells in inflamed dental tissues on periodontal bone regeneration].

ABSTRACT

Tissue engineering has become a research hotspot regarding periodontal bone regeneration in recent years. Generally, stem cells used in periodontal tissue engineering are derived from healthy dental tissues, while restricted due to the strict indication of tooth extraction and limited sources. Stem cells in inflamed dental tissues mainly derive from inflamed pulp, periapical and periodontal tissues. Stem cells in inflamed dental tissues are abundant and retain most of the basic characteristics of stem cell compared with the ones derived from healthy dental tissues, which can be a promising source of stem cells for periodontal bone regeneration. In this review, we summarize the current application and prospect of stem cells in inflamed dental tissues on periodontal bone regeneration, and then discuss their feasibility as seed cells, in order to provide a reference for future research and clinical application of stem cells in inflamed dental tissues.
