Case Report: Patient reported a major complaint of swelling in the palatal region that was present for 6 months. The patient was submitted to non-surgical endodontic treatment. After clinical and radiographic examinations, decompression marsupialization was performed to create a window on the buccal cortical wall and an acrylic resin drain was installed in the depth of the cystic cavity. Two months later, a procedure was planned with cystectomy and apicoectomy on tooth 12, enucleated cyst, bone graft and barrier with purified collagen sponge. After enucleation, a sample of the cystic capsule was examined histologically and the diagnosis of periapical cyst was confirmed. Conclusion: After 1-year, clinical cicatrization and radiographic resolution of the maxillary radiolucency were verified and the patient did not present painful symptoms, demonstrating the success of the treatment performed. http://preprints.ibict.br/handle/1618034/64 http://preprints.ibict.br/handle/1618034/63 Preprint title (English): Are the autistic people at the Covid-19 risk group? An applied plausibility to dental health Author(s): Lima, Fernando José Camello de; Santos Júnior, Valdeci Elias; Lemos, George Azevedo; Oliveira-Neto, Olavo Barbosa de; Lima, Christiane Calheiros Farias de Editor responsible for the desk review: Silva Junior, Geraldo Abstract (English): People within the autism spectrum may find it more difficult to adapt to changes in routines imposed by the COVID-19 pandemic. This change in behavior can lead to changes in habits, such as increasing the frequency of sugar consumption, which also increases the risk of cavities and the need for dental interventions, often without the cooperation of these individuals. This scenario can increase the risk of contagion by SARS-CoV-2, a virus that binds via protein S to the Angiotensin-Converting Enzyme 2 (ACE-2 ), which may be in greater number in the oral and nasal mucosa cells of these individuals, exposing them to contagion during dental care, hence the question: are autistic people in the COVID-19 risk group? http://preprints.ibict.br/handle/1618034/63 http://preprints.ibict.br/handle/1618034/62 Preprint title (English): Apically extruded debris using reciprocating single file and additional use of MaxWire alloy file Author(s): Machado, Amanda Marques; Lima, Carolina Oliveira de; Oliveira, Natália Felizardo de; Santos, Amara Eulalia Chagas; Risso, Patrícia de Andrade Editor responsible for the desk review: Silva-Junior, Geraldo Oliveira Abstract (English): Objective: the aim of this study was to evaluate the amount of apically extruded debris after the preparation with WaveOne Gold and additional use of XP-Endo Finisher file. Material and Methods: Forty human one-rooted premolars were selected and divided into two groups (n=20): WaveOne Gold and WaveOne Gold and XP-Endo finisher. Subsequently, the root canals were instrumented following the manufacturer’s instructions and distilled water was used as irrigant. Apically extruded debris during instrumentation was collected into pre-weighed Eppendorf tubes. The weight of the dry extruded debris was established by subtracting the pre-instrumentation and post-instrumentation weight of the Eppendorf tubes for each group. Results: The data were analyzed using Shapiro-Wilk and Mann-Whitney tests, with significant level of 5%. There was no significant difference between groups (p=0.66) in relation to apically extruded debris. Conclusion: apically extruded debris occurred in both groups; however, the additional use of the XP-Endo Finisher instrument did not contribute to the significant increase of apical extrusion of debris when compared to the isolated use of WaveOne Gold. http://preprints.ibict.br/handle/1618034/62 http://preprints.ibict.br/handle/1618034/61 Preprint title (English): Moral Bullying/Harassment In Scientific Publication Author(s): Silva Junior, Geraldo Oliveira Editor responsible for the desk review: Torres, Thiago da Silva Abstract (English): The purpose of this editorial is to signal why moral harassment occurs in what surrounds the relationship of the chief editors of emerging scientific journals versus co-authors of renowned scientific publications and, also, managers of large research and teaching institutions and what can be done to avoid such behavior. http://preprints.ibict.br/handle/1618034/61
