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...
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...
Bone callus formation is highly disrupted by dietary restriction in growing rat...
Botega,Iara Inácio; Zamarioli,Ariane; Guedes,Patrícia Madalena San Gregório; Silva,Raquel Assed Bezerra da; Issa,João Paulo MardeganAbstract Purpose: To evaluate the effects of food restriction on fracture healing in growing rats. Methods: Sixty-eight male Wistar rats were assigned to two groups: (1) Control and (2) Dietary restriction. After weaning the dietary restricted animals were fed ad libitum for 42 days with 50% of the standard chow ingested by the control group. Subsequently, the animals underwent bone fracture at the diaphysis of...
Undernutrition impairs the quality of growth plate and trabecular and cortical ...
Guedes,Patrícia Madalena San Gregório; Zamarioli,Ariane; Botega,Iara Inácio; Silva,Raquel Assed Bezerra da; Issa,João Paulo MardeganAbstract Purpose: To investigate the effects of dietary restriction on the growth plate and long bone tissue in growing rats. Methods: Sixty male Wistar rats were randomly assigned to two groups: Control (Con) and Diet-restricted (Res). After weaning, the Res rats were offered 50% of the chow ingested by the control (ad libitum food intake). The animals were subdivided into two subgroups with follow-ups up to 5...
Tissue Response after Subcutaneous Implantation of Different Glass Ionomer-Base...
Pucinelli,Carolina Maschietto; Silva,Raquel Assed Bezerra da; Borges,Luã Lopes; Borges,Alberto Tadeu do Nascimento; Nelson-Filho,PauloAbstract The aim of this study was to evaluate the subcutaneous connective tissue response of isogenic mice after implantation of different glass ionomer-based cements (EQUIA® Forte Fil, EQUIA® Fil and Ketac™ Universal Aplicap™). Eighty-seven isogenic BALB/c mice were allocated in 12 groups, 9 were considered as experimental groups (Ketac, E. Fil and E. Forte at 7, 21 and 63 days) and 3 controls (empty polyethy...
Quantification of pro-inflammatory cytokines and osteoclastogenesis markers in ...
Andrucioli,Marcela Cristina Damião; Matsumoto,Mírian Aiko Nakane; Fukada,Sandra Yasuyo; Saraiva,Maria Conceição Pereira; Bergamo,Ana Zilda NazarAbstract Objectives: Miniscrew has been frequently used, considering that anchorage control is a critical point in orthodontic treatment, and its failure, the main adverse problem. Using two groups of stable (successful) and unstable (failed) mini-implants, this in vivo study aimed to quantify proinflammatory cytokines IL-1 α, IL-6, IL-17, and TNF-α and osteoclastogenesis marker RANK, RANKL, and OPG in gingival...
Genetic Polymorphism in MMP9 May Be Associated With Anterior Open Bite in Children
Küchler,Erika Calvano; Barreiros,Driely; Silva,Raphaela Oliveira da; Abreu,Júlia Guimarães Barcellos de; Teixeira,Ellen CardosoAbstract Anterior open bite (AOB) has a multifactorial etiology caused by the interaction of sucking habits and genetic factors. The aim of this study was to evaluate the association between AOB and polymorphisms in genes that encode Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs). Four hundred and seventy-two children that presented at least one sucking habit were evaluated. Children were ...
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...
Stress and Anxiety in Children After the Use of Computerized Dental Anesthesia
Queiroz,Alexandra M.; Carvalho,Ariany B.; Censi,Laís L.; Cardoso,Carmen L.; Leite-Panissi,Christie R.; Silva,Raquel Assed Bezerra daThe aim of this study was to evaluate the transitory stress levels and the anxiety state in children submitted to conventional and computerized dental anesthesia. Twenty children (7 to 12 years) were randomly assigned to receive conventional and computerized dental anesthesia. To investigate the hypothesis that transitory stress could be lower after using computerized anesthesia compared to conventional anesthe...

Rossi,Andiara De; Ferreira,Danielly Cunha Araújo; Silva,Raquel Assed Bezerra da; Queiroz,Alexandra Mussolino de; Silva,Léa Assed Bezerra daAbstract: The objective of this in vitro study was to evaluate the antimicrobial effect of toothpastes containing natural extracts, chlorhexidine or triclosan. The effectiveness of toothpastes containing natural extracts (Parodontax(r)), 0.12% chlorhexidine (Cariax(r)), 0.3% triclosan (Sanogil(r)) or fluoride (Sorriso(r), control) was evaluated against yeasts, Gram-positive and Gram-negative bacteria using the ...
