Effect of ethanol-wet bonding on porosity and retention of fiberglass post to r...
Carvalho,Monize Ferreira Figueiredo de; Yamauti,Monica; Magalhães,Cláudia Silami de; Bicalho,Aline Aredes; Soares,Carlos José; Moreira,Allyson NogueiraAbstract: This in vitro study aimed to assess the effects of different pretreatments used to adapt glass-fiber posts cemented to root canals with different resin cements, regarding porosity percentage and bond strength. Twelve bovine incisor roots were prepared with Largo drills. After post space preparation, the specimens were randomized into two types of pretreatment groups (n = 3): water-wet bonding and etha...
Relevance of Resin for Photoelasticity
Martins,Adriana Vieira; Rocha,Wellington Márcio dos Santos; Silva,Nelson Renato França Alves; Albuquerque,Rodrigo de Castro; Moreira,Allyson NogueiraThe goal of this study is to test photoelastic resins for manufacturing models with teeth and/or implants under chewing load. Four commercial brands have been chosen: Araldite (Ciba Chemicals), Flexible GIV-Rigid GIV (Polipox) and PL2 (Measurements Group). Nine discs were manufactured, four of them from each of the photoelastic resin brands and five from different proportions of mixture between Flexible GIV and...
Lipid accumulation product index in HIV-infected patients: a marker of cardiova...
Guimarães,Milena Maria Moreira; Greco,Dirceu Bartolomeu; Moreira,Allyson Nogueira; Guimarães,Nathalia Sernizon; Freire,Cláudia Maria VilasABSTRACT The lipid accumulation product (LAP) index is an emerging cardiovascular risk marker. We aimed to assess the accuracy of this index as a marker of cardiovascular risk in HIV-infected patients. A cross-sectional study of 133 HIV-infected patients on antiretroviral drugs and 20 non-infected controls was conducted at the outpatient clinic of a referral center of infectious and parasitic diseases. Evaluati...
LED and Halogen Light Transmission through a CAD/CAM Lithium Disilicate Glass-C...
Pereira,Carolina Nemesio de Barros; Magalhães,Cláudia Silami de; Daleprane,Bruno; Peixoto,Rogéli Tibúrcio Ribeiro da Cunha; Ferreira,Raquel da ConceiçãoThe effect of thickness, shade and translucency of CAD/CAM lithium disilicate glass-ceramic on light transmission of light-emitting diode (LED) and quartz-tungsten-halogen units (QTH) were evaluated. Ceramic IPS e.max CAD shades A1, A2, A3, A3.5, high (HT) and low (LT) translucency were cut (1, 2, 3, 4 and 5 mm). Light sources emission spectra were determined. Light intensity incident and transmitted through ea...
Definitive Presurgical CAD/CAM-Guided Implant-Supported Crown in an Esthetic Area
Barros,Vinicius de Magalhães; Costa,Natália Rafaela de Assis; Martins,Paulo Henrique Fonseca; Vasconcellos,Walison ArthusoThis paper describes the digital workflow from cone beam computer tomography (CBCT) to the installation of a definitive presurgical zirconium individual crown in a 19-year-old woman requiring implant replacement of a maxillary right lateral incisor. The patient had agenesis of this tooth and had completed the orthodontic treatment. CBCT was conducted and diagnostic casts were digitized. Virtual planning was com...
Effect of chlorhexidine varnish on gingival growth in orthodontic patients: a r...
Pretti,Henrique; Barbosa,Gabriella Lopes de Rezende; Lages,Elizabeth Maria Bastos; Gala-García,Alfonso; Magalhães,Claudia Silami deIntroduction: Fixed orthodontic appliances patients suffer limitations on the effective control of biofilm by mechanical methods, bringing the need of a coadjutant in the control of inflammation and oral health improvement.Objective: The aim of this prospective split-mouth blind study was to analyze the effect of a 40% chlorhexidine (CHX) varnish on gingival growth of patients with orthodontic fixed appliances....
Standard of disocclusion in complete dentures supported by implants without fre...
Greco,Gustavo Diniz; Las Casas,Estevam Barbosa de; Cornacchia,Tulimar P. Machado; Magalhães,Cláudia Silami de; Moreira,Allyson NogueiraOBJECTIVE: The occlusal patterns are key requirements for the clinical success of oral rehabilitation supported by implants. This study compared the stresses generated by the disocclusion in the canine guide occlusion (CGO) and bilateral balanced occlusion (BBO) on the implants and metallic infrastructure of a complete Brånemark protocol-type denture modified with the inclusion of one posterior short implant on...

Validity of two occlusal indices for determining orthodontic treatment needs of...
Costa,Rodrigo Norremose; Abreu,Mauro Henrique Nogueira Guimarães de; Magalhães,Claudia Silami de; Moreira,Allyson NogueiraThe aim of the present study was to validate the dental aesthetic index (DAI) and index of complexity, outcome and need (ICON) based on the opinions of a panel of Brazilian orthodontists. A comparison of these two orthodontic treatment need indices was carried out based on the consensus of a panel of 20 experienced orthodontists. A set of 108 study casts representing the full spectrum of malocclusions was selec...
