Objective: To generate teledentistry protocols for urgent and priority dental care for the elderly population through a technological web platform and mobile application in the context of the COVID-19 pandemic. Material and Methods: Teledentistry protocols were developed in five sequential steps: Staff training, Patient recruitment, Patient admission, Patient reception and Patient care. Reasons for admission were categorized in urgencies and priority dental treatment. Results: The most prevalent reasons for consultation were prosthesis mismatch (18.37%), dental pain (16.33%) and fractured teeth (14.29%). In urgencies by need for treatment: due to infection or pain (24.44%) or to avoid pulp involvement (26.67%). The rest of the care did not require immediate attention. Regarding the OHIP-14Sp survey prior to care, in which patients were consulted for problems with their teeth, mouth or prosthesis, two questions were answered per dimension, for each dimension the following values were obtained: functional limitation (71.30% and 50.44%), physical pain (68.97% and 70.18%), psychological discomfort (75.00% and 74.14%), physical disability (57.39% and 46.09%), psychological disability (37.72% and 53.91%), social disability (33.91% and 30.97%) and handicap (27.83% and 25.86%). Conclusion: A teledentistry protocol for urgent and priority dental care of the elderly in the context of the COVID-19 pandemic with a focus on a general dentist remotely supported specialists was a useful tool to effectively systematize the care of elderly patients, reducing risk of exposure to COVID-19 and solving dental urgencies in this population

The aim of this study was to determine the morphogeometric patterns of the interforaminal region from cone beam computed tomography (CBCT) scans of individuals with total mandibular edentulism. CBCT images were obtained from 40 patients with total edentulism who are older (12 men and 28 women; average age of 69.5 ± 9.4 years) and who wore a non-implant-supported, lower, removable, total prosthesis. We conducted a two-dimensional (2D) morphogeometric analysis of the Digital Imaging and Communication in Medicine (DICOM) files from the CBCT scans, and five equidistant cross sections were planned. For the three-dimensional (3D) morphogeometric analysis, standard triangular language (STL) files were obtained after segmentation of the interforaminal mandibular region, and four anatomical landmarks and their respective curves were digitized. The patterns among the shapes were determined using principal component analysis (PCA) on MorphoJ software (version 1.07a). The results of the 2D morphogeometric analyses for PCA of the interforaminal mandibular paramedian region were PC1 or elongated drop shape, 54.78%; PC2 or wineskin shape, 17.65%; PC3 or pear shape, 11.77%; and PC4 or eggplant shape, 5.71%, and those for PCA of the symphyseal region were PC1 or elongated drop shape, 62.13%; PC2 or ovoid shape, 11.64%; PC3 or triangular shape, 9.71%; and PC4 or tuber shape, 4.96%. The results of the 3D morphogeometric analyses for the interforaminal hemimandibular region were PC1, 59.83%; PC2, 10.39%; PC3, 7.67%; and PC4, 5.09%. This study provides relevant information for future clinical guidelines on prosthetics and implants, in addition to proposing the use of new technologies that support diagnosis and treatment in patients with edentulism.
