This study is a single-center, prospective, single-arm study to evaluate the efficacy and safety of pulp regeneration induced by SHED mixed with hyaluronic acid polymerization in patients with pulp necrosis of permanent teeth. This study plans to include 30 subjects from the Department of Stomatology of the Fifth Affiliated Hospital of Guangzhou Medical University. All participants in this study will receive stem cells from human exfoliated deciduous teeth (SHED) mixed with hyaluronic acid polymers after the preparation and disinfection of the root canal of the affected teeth. All participants will undergo screening and baseline visits. After surgery, the participants will be followed up for 2 years.
Dental pulp necrosis is one of the most common pathological conditions that results in tooth loss. However, regeneration of functional dental pulp has proved difficult. Therefore, the investigators conduct a single-arm study to evaluate the efficacy and safety of pulp regeneration induced by SHED mixed with hyaluronic acid polymerization in patients with pulp necrosis of permanent teeth.
