Delayed Cutaneous Adverse Reaction of the AstraZeneca COVID-19 Vaccine in a Bre...
Diogo, Patrícia; Correia, Gil; Martins, João B.; Soares, Rui; Palma, Paulo J.; Santos, João Miguel; Gonçalves, TeresaThe ChAdOx1 nCoV-19 vector vaccine (Vaxzevria, AstraZeneca, Cambridge, UK) was developed at Oxford University and is considered safe for the administration in lactating mothers. Nevertheless, as a novel vaccine, there are gaps in the knowledge regarding possible adverse events in breastfeeding infants of vaccinated mothers. This case report provides first-time data on a possible delayed, cutaneous, adverse reac...
IoT lysimeter system with enhanced data security
Almeida, Carlos; Santos, João Miguel; Caeiro, José; Martins, JoãoDiverse sources of data related to precision agriculture may be acquired with devices using an IoT architecture. Lysimeters are used to measure the amount of actual evapotranspiration released by plants, which is an important parameter for agriculture. New proposals of lysimeters extend the capabilities of these devices taking advantage of modern electronics, sensors, Internet, and computing devices. The paper ...
Smart Lysimeter with Crop and Environment Monitoring
Almeida, Carlos; Santos, João Miguel; Caeiro, José; Oliveira, Henrique; Martins, JoãoA model of a smart lysimeter, adopting an IoT approach, enhanced with pest and crop state analysis is presented. Besides the measurement of the traditional evaporation-transpiration balance, the lysimeter senses additional parameters like the soil temperature and humidity at different depths; air temperature and humidity; sunlight exposition (visible and infrared). Additionally, the system can capture high-reso...
Vital Pulp Therapy in Permanent Mature Posterior Teeth with Symptomatic Irrever...
Santos, João Miguel; Pereira, Joana F.; Marques, Andréa; Sequeira, Diana B.; Friedman, ShimonBackground and Objectives: Symptomatic irreversible pulpitis in permanent mature teeth is a common indication for nonsurgical root canal treatment (NSRCT), but contemporary studies have reported on vital pulp therapy (VPT) applied in such teeth as a less invasive treatment. This systematic review assessed the outcomes of VPT, including partial and full pulpotomy performed with hydraulic calcium silicate cements...
Subcutaneous Implantation Assessment of New Calcium-Silicate Based Sealer for W...
Santos, João Miguel; Coelho, Carolina M.; Sequeira, Diana B.; Marques, Joana A.; Pereira, Joana F.; Sousa, Vítor; Palma, Paulo J.; Santos, Ana C. G.Calcium silicate-based sealers were recently introduced as a new class of endodontic sealers, with potential further benefits due to their bioactivity. The aim of this study was to evaluate the biocompatibility of two new hydraulic calcium silicate-based sealers, TotalFill BC Sealer (FKG, La Chaux-des-Fonds, Switzerland) and TotalFill BC Sealer HiFlow (FKG, La Chaux-des-Fonds, Switzerland) through subcutaneous ...
Symplectic Keys and Demazure Atoms in Type C
Santos, João MiguelWe compute, mimicking the Lascoux-Sch utzenberger type A combinatorial procedure, left and right keys for a Kashiwara-Nakashima tableau in type C. These symplectic keys have a similar role as the keys for semistandard Young tableaux. More precisely, our symplectic keys give a tableau criterion for the Bruhat order on the hyperoctahedral group and cosets, and describe Demazure atoms and characters in type C. The...
Tooth Discoloration after Regenerative Endodontic Procedures with Calcium Silic...
Palma, Paulo J.; Marques, Joana A.; Santos, Joana; Falacho, Rui I.; Sequeira, Diana B.; Diogo, Patrícia; Caramelo, Francisco; Ramos, João C.The aim of the present ex vivo study was to assess and compare coronal discoloration induced by four endodontic biomaterials used in regenerative endodontic procedures (REPs). Root resection was executed horizontally, 2 mm apical to the cementoenamel junction, in all fifty-four teeth. After accessing the pulp chamber, specimens were randomly divided in groups and filled with either saline solution or blood, fol...
Evaluation of Root-End Preparation with Two Different Endodontic Microsurgery U...
Palma, Paulo J.; Marques, Joana A.; Casau, Margarida; Santos, André; Caramelo, Francisco; Falacho, Rui I.; Santos, João MiguelThe aim of this study is to compare root-end preparation performed with two different ultrasonic tips-CVDentus and NSK-and respective time requirements. After root-end resection, 32 teeth were randomly divided in two groups, according to the ultrasonic tip used for root-end preparation. Preparation time was recorded. Photomicrographs were taken to assess the following parameters: root surface microcracking, mar...
Long-Term Prognosis of Endodontic Microsurgery-A Systematic Review and Meta-Ana...
Pinto, Diogo; Marques, Andréa; Pereira, Joana F.; Palma, Paulo J.; Santos, João MiguelBackground and objectives: The long-term outcome of endodontic microsurgery (EMS) performed on root-filled teeth affected by post-treatment apical periodontitis (AP) has been a matter of debate, re-launched by the introduction of novel root-end filling materials which have been proven to improve the short-term outcome of EMS. The purpose of this systematic review and meta-analysis is to evaluate the clinical an...
Six-Month Color Stability Assessment of Two Calcium Silicate-Based Cements Used...
Palma, Paulo J.; Marques, Joana A.; Falacho, Rui I.; Correia, Eder; Vinagre, Alexandra; Santos, João Miguel; Ramos, João C.Aim: The purpose of the present study is to assess the color stability of two calcium silicate-based cements (CSCs) used in regenerative endodontic procedures (REPs). Methods: A total of 40 acrylic single-rooted transparent teeth, with immature apex, were used. Root canals were filled up to 3 mm below the level of the cementoenamel junction, with either saline solution (Mineral Trioxide Aggregate (MTA)/saline a...
