Objective: To evaluate the wound healing of recipient and donor sites following keratinized mucosa augmentation (KMA) around implants in reconstructed jaw areas and to compare these outcomes with gingival grafts in native jawbone, so as to provide clinical guidance for postoperative maintenance, and to investigate the impact of clinical experience on the evaluation of KMA postoperative healing through subgroup comparisons.
Methods: This study included patients who underwent resection of maxillofacial tumors, fibular or iliac flap reconstruction, and implant placement at Peking University Dental Hospital from October 2020 to April 2023. Three months post-implant placement, the patients were referred for KMA procedures.
Comparative Histological Assessment of Zinc Oxide Nanoparticles and Low-Power Laser Treatment at 810nm Wavelength on the Recovery of Second-Degree Burn Wounds in Rat Models.

The utilization of zinc oxide nanoparticles is thought to augment wound healing because of their antibacterial characteristics and capacity to stimulate cellular regeneration, especially in instances of minor burn injuries. On the other hand, it has been shown that tissue regeneration is aided by low-power laser therapy via photobiomodulation. Zinc oxide nanoparticles and low-power laser therapy are the two therapeutic modalities that will be compared in this study in order to assess how well they promote healing after burn injury and provide important new information on improved wound care techniques.

Soft tissue deficiency around dental implants can negatively impact outcomes in terms of esthetics and long-term stability. While autogenous connective tissue grafting is still considered the gold standard treatment, alternative approaches are being proposed primarily to enhance patient comfort and avoid invasive procedures such as two-sites surgeries using xenogeneic collagen matrices. Despite the advantages, the quality of the regenerated tissues remains unpredictable and, in many cases, questionable, highlighting the need for alternative and innovative approaches.

adnexal tumors are recently named tumors of the female adnexal region, associated with Peutz-Jeghers syndrome (PJS). There is a lack of studies on the clinical phenotypes of PJS concerning the pathology and molecular characteristics of adnexal tumors. We searched for 781 relevant studies through PubMed and Web of Science, and preliminary statistical and grouping comparisons were made using the screened study data combined with our patient.

Aim: To investigate additional factors contributing to the pathophysiology of chemotherapy-induced oral mucositis and periodontitis beyond the systemic immune suppression caused by the chemotherapeutic agent 5-Fluorouracil (5-FU).
Methods: 5-Fluorouracil was topically delivered to the non-keratinized, rapidly proliferating junctional epithelium (JE) surrounding the dentition, and acts as an immunologic and functional barrier to bacterial ingression. Various techniques, including EdU incorporation, quantitative immunohistochemistry (qIHC), histology, enzymatic activity assays, and micro-computed tomographic (μCT) imaging, were employed to analyze the JE at multiple time points following topical 5-FU treatment.
