We discuss recent advances in photo-responsive theranostic nanoplatforms for dental disease management and evaluate their mechanisms, performance and future design principles.

Oral implantology is a discipline that combines theory and practice, and its research involves many fields such as ecology, psychology, and genetics. In view of the clinical application of this subject, this article will discuss the practice of combined PBL (problem-based learning) teaching method, introduce the background and significance of this topic in detail, and analyze the current status and development trends of related research at home and abroad. Next, this article combines PBL teaching method to design a model for oral implantology teaching at the postgraduate level, and discovers problems through experimental results and actual situations. The experimental results showed that the average score of the experimental class was 89.3 points, while the average score of the control class was 74.3 points; the participation rate of the experimental class ranged from 93% to 96%, while the participation rate of students in the control group ranged from 82% to 88%. The overall performance of students in the experimental group who have been trained by PBL teaching method is better than that of students who have not been trained, which shows that this method is feasible and can improve the effect of oral implantology teaching.

Implant-associated infections (IAIs) persist as a critical complication in biomaterial transplantation, driven by rapid microbial colonization, biofilm encapsulation, and escalating antibiotic resistance. Conventional antibiotic-based treatments and passive antimicrobial coatings often fail to achieve long-term infection control due to limited biofilm penetration, localized cytotoxicity, and active agent depletion. To overcome these limitations, piezoelectric nanocomposite coatings utilize a dynamic, stimulus-responsive framework that converts physiological mechanical forces or external ultrasound into localized electrical signals. These surface-bound electric fields systematically mitigate bacterial adhesion, eradicate mature biofilms via targeted reactive oxygen species (ROS) generation, disrupt microbial metabolic pathways, and favorably modulate the peri-implant immune microenvironment while supporting host tissue repair. This review evaluates the material design principles and classifications of inorganic, organic, and hybrid piezoelectric nanocoatings. We detail their multifaceted antibacterial mechanisms and trace their therapeutic potential in orthopedic and dental implants, as well as wound management. Lastly, we analyze current engineering bottlenecks to chart a clear trajectory for their clinical translation.
