Objective To assess the effectiveness of combining problem-based learning (PBL), team-based learning (TBL), and clinical pathway (CP) in standardized training of periodontology residents. Methods A total of 48 residents who were transferred to the Department of Periodontology at the Fourth Affiliated Hospital of Harbin Medical University from January to October 2023 were randomly assigned to either the traditional teaching group or the PBL, TBL, and CP combined teaching group, with 24 participants in each group. The traditional teaching group followed conventional teaching methods, while the PBL, TBL, and CP combined teaching group utilized a combination of these three methods. Prior to completing their rotation, both groups underwent professional assessments as well as surveys on satisfaction with standardized training and self-evaluation. Results The professional examination scores ofcombined teaching group were significantly higher than those of the traditional teaching method group (P0.05). However, compared to the traditional teaching group, students in the PBL, TBL, and CP combined teaching group showed significant improvements in doctor-patient communication skills, active information retrieval abilities, learning interest levels, team discussions, and clinical logical thinking abilities (P

Sonodynamic therapy (SDT) is a cutting-edge method for the biological effects of ultrasound combined with sound-sensitive agents. In recent years, SDT has been a concern of experts and scholars in the oral field, and a series of experimental studies has been carried out. We will introduce the progress of SDT in the field of stomatology from three aspects: the therapeutic mechanism of SDT, the application of SDT in the oral field, and the current situation and future of SDT in the treatment of oral diseases. It is currently believed that singlet oxygen theory, cavitation effects, and induction of apoptosis are the main therapeutic mechanisms. The research of SDT on oral disease prevention mainly focuses on oral tumors (especially squamous cell carcinoma and osteosarcoma) and infectious diseases (such as periodontitis, maxillofacial infection, and oral mucosal disease). Although the current research is still in the experimental stage, with the continuous exploration of sonosensitizers and nanotechnology, SDT will provide great help for the clinical prevention and treatment of oral diseases in the future.
