Online teaching, quality of life and anxiety of Brazilian dental professors dur...
Pucinelli,Carolina Maschietto; Oliveira,Angélica Aparecida de; Nelson Filho,Paulo; Silva,Léa Assed Bezerra da; Castro,Guilherme Piedade Assed deAbstract: The COVID-19 pandemic led to changes in academic teaching and dental education, but the impact on dental professors’ mental health and quality of life remains poorly understood. Thus, the objective of this study was to evaluate the impacts of social distancing and online teaching related to COVID-19 on the quality of life and anxiety of Brazilian dental professors. This was a cross-sectional study con...
Cytotoxicity and Inflammatory Mediators Release by Macrophages Exposed to Real ...
Silva,Léa Assed Bezerra da; Hidalgo,Lídia Regina da Costa; de Sousa-Neto,Manoel Damião; Arnez,Maya Fernanda Manfrin; Barnett,FredericAbstract This study evaluated the cytotoxicity of Sealapex Xpress and Real Seal XT and their effect on macrophage activation. J774.1 macrophages were incubated with Sealapex Xpress and Seal Real XT (0.1, 1.0, and 10 mg/mL) for 24 and 48 h. Cell viability was assessed by the MTT assay and macrophage activation was measured by pro- and anti-inflammatory cytokine production using ELISA. Data were analyzed using on...
Association between Estrogen, Vitamin D and Microrna17 Gene Polymorphisms and P...
Silva-Sousa,Alice Corrêa; Mazzi-Chaves,Jardel Francisco; Freitas,Jessica Vavassori; Salles,Alessandro Guimarães; Segato,Raquel Assed Bezerra da SilvaAbstract This study evaluated the association between polymorphisms in genes encoding estrogen receptors 1 (ESR1) and 2 (ESR2), vitamin D receptor (VDR) and in microRNA17 (which binds to ESR1 and VDR) with persistent apical periodontitis (PAP) after the endodontic treatment. We included 162 patients who completed endodontic treatment at least one year ago and presented apical periodontitis at the beginning of t...
Negative Pressure Irrigation Presents Mineralizing Potential in Dogs’ Immature ...
Silva,Léa Assed Bezerra da; Linhares,Marcela Lopes; Silva,Raquel Assed Bezerra da; Nelson-Filho,Paulo; Lucisano,Marília PacíficoAbstract The objective of this in vivo study was to assess the effect of the root canal irrigation by negative and positive apical pressure on the expression of molecules that are an indicative of cell differentiation with mineralizing phenotype in teeth of dogs with incomplete rhizogenesis and induced periapical lesion. A total of 30 teeth (60 roots) were distributed into 3 groups (n=20): EndoVac®, Conventiona...
Radiographic and Immunohistochemical Evaluation of Root Canal Treatment Using D...
Jesus,Sidinéia Feitoza de; Cohenca,Nestor; Romualdo,Priscilla Coutinho; Nelson-Filho,Paulo; Queiroz,Alexandra Mussolino de; Sousa-Neto,Manoel DamiãoAbstract The aim of this study was to evaluate the radiographic periapical repair and the synthesis of inflammatory mediators after endodontic treatment in a single session, using different irrigation protocols, in teeth with apical periodontitis. Experimental apical periodontitis were induced in dog’s teeth randomly assigned into 4 groups: G1 - Irrigation by Negative Apical Pressure (n= 20); G2 - Passive Ultra...
Periapical bone response to bacterial lipopolysaccharide is shifted upon cycloo...
Ribeiro-Santos,Fernanda Regina; Silva,Geyson Galo da; Petean,Igor Bassi Ferreira; Arnez,Maya Fernanda Manfrin; Silva,Léa Assed Bezerra daAbstract Objectives: Infection, inflammation and bone resorption are closely related events in apical periodontitis development. Therefore, we sought to investigate the role of cyclooxygenase (COX) in osteoclastogenesis and bone metabolism signaling in periapical bone tissue after bacterial lipopolysaccharide (LPS) inoculation into root canals. Methodology: Seventy two C57BL/6 mice had the root canals of the fi...
Influence Of Genetic Polymorphisms In Genes Of Bone Remodeling And Angiogenesis...
Mazzi-Chaves,Jardel Francisco; Petean,Igor Bassi Ferreira; Soares,Isadora Mello Vilarinho; Salles,Alessandro Guimarães; Antunes,Lívia Azeredo AlvesAbstract Persistent apical periodontitis (AP) is a situation involving an inflammatory and immune response caused mainly by anaerobic polymicrobial infection of the root canal system and the outcome and follow-up of the root canal treatment has been reported as intimately related to host response. The apical periodontitis repair might be associated with genetic polymorphisms. This study aimed to evaluate the as...
Timing of Permanent Tooth Emergence is Associated with Overweight/Obesity in Ch...
Evangelista,Silvane e Silva; Vasconcelos,Katia Regina Felizardo; Xavier,Thaís Aparecida; Oliveira,Sara; Dutra,André Luiz Tannus; Nelson-Filho,PauloAbstract The aim of this study was to evaluate the association between timing of permanent tooth emergence with overweight and obesity in children from Brazilian Amazon region. The studied population consisted of 192 children, 09 to 12 year-old, from public schools at Manaus, Amazonas-Brazil. Clinical examination was performed and the tooth emergence was evaluated according to the number of permanent erupted te...
Mechanical Preparation Showed Superior Shaping Ability than Manual Technique in...
Hidalgo,Lídia Regina da Costa; Silva,Léa Assed Bezerra da; Leoni,Graziela Bianchi; Mazzi-Chaves,Jardel Francisco; Carvalho,Emily Eduardo da SilvaAbstract The aim of the study was to evaluate canal preparation in primary molars with hand files, ProTaper Next and Self-Adjusting File (SAF) by 2D and 3D micro-computed tomography (micro-CT) analysis. Canals of 24 primary molars were prepared with hand files (HF), ProTaper Next (PTN) and SAF (n=8/group). The teeth were scanned before and after root canal preparation and the pre- and postoperative micro-CT ima...
Apical Negative Pressure irrigation presents tissue compatibility in immature t...
Pucinelli,Carolina Maschietto; Silva,Léa Assed Bezerra da; Cohenca,Nestor; Romualdo,Priscilla Coutinho; Silva,Raquel Assed Bezerra da; Consolaro,AlbertoAbstract Aim: To compare the apical negative pressure irrigation (ANP) with conventional irrigation in the teeth of immature dogs with apical periodontitis. Methods: Fifty-two immature pre-molar root canals were randomly assigned into 4 groups: ANP (n=15); conventional irrigation (n=17); healthy teeth (control) (n = 10); and teeth with untreated apical periodontitis (control) (n=10). After induction of apical p...
