Exclusion criteria:

1. Those with severe periodontal disease (alveolar bone resorption exceeding two-thirds of the tooth root length) or whose occlusal trauma affects the interpretation of the research results; 2. Those with a distance from the lowest point of the periodontal pocket beneath the tooth to the root apex <= 3mm, or with combined periodontal-pulp lesions, or who have undergone implantable periodontal surgery with artificial materials within 1 year; 3. Those with untreated acute infections, root apex lesions, root fractures, severe root deformities, non-erodible dental bone/ enamel protrusions, enamel-dental cement junctions or untreated caries on the root surface, or non-matching edges of the restoration below the gum and/or at the enamel-dental cement junction or beneath it for the tooth and adjacent teeth; 4. Those with malignant tumors, abnormal immune system (autoimmune diseases, etc.), blood diseases, heart system diseases, systemic diseases that may cause oral problems (Behcet's disease, etc.), or a history of mental and cognitive disorders; 5. Those with positive results for any of the following tests during screening: hepatitis B core antigen (HBcAg), hepatitis C virus antibody (HCV-Ab), human immunodeficiency virus antibody (HIV-Ab), or Treponema pallidum antibody (TP-Ab); 6. Those with a glycated hemoglobin level > 7.0% within 3 months before screening; 7. Smokers (smoking >= 10 cigarettes per day within 6 months before screening); 8.
