COVID-19 Adaptations for Biomedical Teaching and Assessment Within the Undergraduate Dental Curriculum.

The COVID-19 pandemic has profoundly affected the provision of teaching and assessment on the undergraduate dental programme in many institutions worldwide, and for a prolonged period resulted in the cessation of face-to-face teaching. This resulted in significant changes in the way that didactic and preclinical skills have been taught and required novel thinking to overcome the issues that COVID-19 restrictions presented.Dentistry is a very practical subject and at this institution, the University of Glasgow Dental Hospital and School, we had to quickly develop new ways of teaching that allowed us to cover teaching and assessment of the required Intended Learning Outcomes. This chapter highlights some specific case studies of how adaptations were made to the undergraduate dental teaching program within our institution utilising technology and visualisation to promote this during this turbulent time. These included teaching of head and neck anatomy, teaching of pre-clinical skills in placement of local anaesthetic and dental extraction forceps, communication skills as well as describing a raft of modifications to our assessment programme.Many of these innovations, utilising blended learning methodologies with the use of visualisation, have been transferred into other areas of teaching within the curriculum and will replace older material as we transition out of the pandemic, undoubtedly significantly improving the student experience.

Nanoimprinting of biomedical polymers reduces candidal physical adhesion.

Management of fungal biofilms represents a significant challenge to healthcare. As a preventive approach, minimizing adhesion between indwelling medical devices and microorganisms would be an important step forward. This study investigated the anti-fouling capacity of engineered nanoscale topographies to the pathogenic yeast Candida albicans. Highly ordered arrays of nano-pit topographies were shown to significantly reduce the physical adherence capacity of C. albicans. This study shows a potential of nanoscale patterns to inhibit and prevent pathogenic biofilm formation on biomedical substrates.

Developments in autotransplantation of teeth.

Transplantation of teeth has been done for hundreds of years. In the late 18th and early 19th century transplants of teeth between individuals were relatively common at specialist dental practices in London. Surprisingly tooth allotransplants have been found to last 6 years on average. In Scandinavia during the 1950 and 1960's autotransplantation of teeth began to be carried out under increasingly controlled conditions. These have proved to be very successful in long term studies with autotransplants surviving up to 45 years post-surgery. Recent developments in cone beam CT and rapid 3D prototyping have enabled the fabrication of accurate surgical templates which can be used to prepare the recipient site immediately prior to transplantation. This has resulted in a drastically reduced extra-oral time for the transplant teeth which can be expected to improve success rates further. Autotransplants provide significant advantages compared to single tooth implants and should be considered the treatment of choice in the growing child.

Autotransplantation of an immature premolar, with the aid of cone beam CT and computer-aided prototyping: a case report.

UNLABELLED: Autotransplantation of immature teeth has good survival rates, and has benefits over ossointegrated implants in the growing child, but is very technique sensitive. Spiral CT imaging has been previously used in adult patients to enable computer-aided prototyping to produce a surgical template of the donor tooth, further increasing success rates. CASE REPORT: The case presented describes management of a 9-year-old girl with the combination of hypodontia affecting the upper lateral incisors as well as a severely ectopic maxillary canine. Cone beam CT was used in combination with computer-aided prototyping to produce a surgical template of an immature mandibular second premolar. The surgical template was used to prepare the transplant site before the donor tooth was extracted, greatly reducing the time from extraction to implantation. By 6 months posttransplant the tooth was clinically sound, and continued root development and laying down of dentine was visible radiographically. DISCUSSION: This paper demonstrates the use of a novel technique to aid the surgical procedure of autotransplantation of immature premolar teeth. The use of autotransplantation in this case allowed the difficult situation of two missing units in the upper left quadrant to be reduced to one unit, while retaining symmetry in the upper arch. Compared to previous studies, the use of cone beam CT to create a 3D prototype reduced radiation dose compared to spiral CT and drastically reduced the extra-oral time of the donor tooth from extraction to transplantation.
