RESUMEN
OBJECTIVE/BACKGROUND: Access to oral health care among older adults is a key issue in society, which has been exacerbated by social distancing measures and lockdowns during the COVID-19 pandemic. Older adults would greatly benefit from teledentistry, yet little information exists on the enablers and challenges of adopting this technology for use with this group. The aim of this scoping review is to summarise the applications and key factors associated with the adoption of teledentistry among older adults. MATERIALS AND METHODS: This scoping review was developed in accordance with Arksey and O'Malley's five-stage framework and the Joanna Briggs Institute scoping review protocol guidelines. Publications on teledentistry involving direct clinical services for older adults aged 60 and above were included. Publications that focused solely on teleeducation were excluded. A systematic search was carried out on major electronic databases until 25 August 2020. Out of 1084 articles screened, 25 articles were included. Facilitators and barriers were categorised using the socio-ecological model. RESULTS/DISCUSSION: Teleconsultation and telediagnosis were the most reported applications of teledentistry among older adults. Reported policy-level factors were data privacy issues (n = 7) and regulations (n = 17). Community-level facilitators and barriers included the availability of resources (n = 15) and support (n = 3). Familiar care settings (n = 2) and effective administration (n = 20) were key organisational-level factors. Staff attitudes and education (n = 23) and individual patient knowledge, attitudes and practices (n = 10) can influence teledentistry adoption while complex medical conditions (n = 8) may pose a challenge. CONCLUSION: Key factors in the uptake of teledentistry among older adults span across policy, community, organisational, interpersonal and individual factors. Commonly reported barriers included technical issues, lack of funding, consent issues and cognitive impairments.

PURPOSE: The primary objective of this study was to evaluate how the utilization of virtual surgical planning (VSP) and the epidemiological profile of patients undergoing orthognathic surgery (OGS) have changed in the past decade. METHODS: The records of patients who had undergone orthognathic surgery at a national dental hospital were reviewed. Trends in VSP, epidemiological data, presentation of dentofacial deformity, and management details were recorded. RESULTS: A total of 1184 patients were included in this study. The majority of the patients seeking treatment in this dental hospital were young Chinese adults with dentofacial deformities requiring bimaxillary surgeries. Most patients presented with a skeletal Class III pattern (79.0%), and asymmetry was diagnosed in 80.8% of all cases. CONCLUSION: There was an initial slow pick-up rate for VSP, but this rapidly increased to a high adoption rate of 98.7-100% between 2019 and 2021. Together with an increasing body of evidence suggesting greater accuracy in VSP, utilization in this technology can be enhanced with greater familiarity with the technology and improvements in the VSP services.
RESUMEN
OBJECTIVES: The primary aim of this study was to assess the linear and geometric accuracy of 3-dimensional (3D) printed tooth replicas when compared to the actual tooth. The secondary aims were to compare the accuracy of three different 3D printers and to evaluate dimensional changes of tooth replicas after sterilization. METHODS: A sample of 16 teeth were selected from recruited patients. Segmentation was carried out to generate files from the patient's cone beam computed tomography (CBCT) data, Tooth replicas were then printed using three printers making use of Polyjet, laser stereolithography (SLA) and digital light processing (DLP) technology respectively. These replicas, along with the actual tooth, were scanned by an optical scanner. Replicas were sent for sterilization and scanned again. Paired superimposition of the scans was performed. RESULTS: A mean length difference of 0.36 mm and mean geometric (root mean square [RMS]) difference of 0.56 mm was found. Qualitative analysis showed that the replicas were generally larger in size. Repeated ANOVA tests showed that the Polyjet printer had the highest accuracy (p<0.0001). After sterilization, there was an overall mean length difference of 0.10 mm and RMS deviation of 0.02 mm. CONCLUSION: This study found that there was a significant difference in linear and geometric measurements of the tooth replicas when compared to the actual tooth. This study also provides evidence that the printer which made use of Polyjet technology was able to produce more accurate models than SLA or DLP printers. Printed tooth models demonstrated clinically insignificant changes after heat sterilization. CLINICAL SIGNIFICANCE: 3D printed tooth replicas derived from the patient's CBCT data may be used in autotransplantation to increase predictability of the procedure. In order for this novel digital approach to realize its potential, it is critical to address questions as to how accurate the various printing technologies are in fabricating replicas.
