Periodontal Regeneration of Chronic Periodontal Disease Patients Receiving Stem Cells Injection Therapy

Phase 1

• Conditions: Periodontal Diseases

• Registration Number: NCT02523651
• Lead Sponsor: Songlin Wang

Brief Summary

The purpose of this study is to evaluate the safety of clinical injection of allogeneic human dental pulp stem cell(DPSC) in local infected periodontal tissue and determine whether injection of allogeneic DPSC is a effective way in the treatment of chronic periodontal disease.

Detailed Description

This study will involve 40 patients who were diagnosed as chronic periodontitis will receive periodontal scaling and root planing. Patients will randomly be divided at the base line into two groups.In test group, 20 chronic periodontitis patients will be treated using local DPSC injection. Whereas, a control group will contain 20 patients who will be treated using placebo. Clinical examination including Quigley-Hein plaque index (QHI), bleeding on probing (BoP), probing depth (PD), clinical attachment level (CAL), and gingival recession (GR) will be perform in different time points during the study. Radiographic and clinical examination will be carried out during the late healing phase up to 12 months post operation.
