Effect of Post-Space Irrigation with NaOCl And CaOCl at Different Concentration...
Seballos,Vivian Gehm; Barreto,Mirela Sangoi; Rosa,Ricardo Abreu da; Machado,Eduardo; Valandro,Luiz Felipe; Kaizer,Osvaldo BazzanAbstract The aim of this study was to evaluate the effect of post-space irrigation with NaOCl and CaOCl at different concentrations on the bond strength of posts cemented with a self-adhesive resin cement. Eighty premolars were sectioned 14 mm from the apex, and endodontically treated. The root canal filling was partially removed. Specimens were randomly assigned into 8 groups (n=10), according to the irrigant ...
Prevalence of sleep bruxism in children: A systematic review
Machado,Eduardo; Dal-Fabbro,Cibele; Cunali,Paulo Afonso; Kaizer,Osvaldo BazzanINTRODUCTION: Prevalence of sleep bruxism (SB) in children is subject to discussions in the literature.OBJECTIVE: This study is a systematic literature review aiming to critically assess the prevalence of SB in children.METHODS: Survey using the following research databases: MEDLINE, Cochrane, EMBASE, PubMed, Lilacs and BBO, from January 2000 to February 2013, focusing on studies specifically assessing the prev...
Influence of Endodontic Sealer Composition and Time of Fiber Post Cementation o...
Rosa,Ricardo Abreu da; Barreto,Mirela Sangoi; Moraes,Rafael do Amaral; Broch,Juliana; Bier,Carlos Alexandre Souza; So,Marcus Vinicius ReisThis study aimed to assess the influence of the type of endodontic sealer (salicylate resin-based sealer vs. two endodontic sealers) and the time of fiber post cementation after root filling on the post adhesion to bovine root dentin. Sixty bovine roots were assigned to six groups (n=10), considering an experimental design with two factors (factorial 3x2): endodontic sealer factor in three levels [epoxy resin-b...
In vitro wear resistance of three types of polymethyl methacrylate denture teeth
Reis,Katia Rodrigues; Bonfante,Gerson; Pegoraro,Luiz Fernando; Conti,Paulo Cesar Rodrigues; Oliveira,Pedro Cesar Garcia de; Kaizer,Osvaldo BazzanThe wear resistance of denture teeth is important to the longevity of removable prostheses of edentulous patients. The ability of denture teeth to maintain a stable occlusal relationship over time may be influenced by this property. The purpose of this in vitro study was to evaluate the wear resistance of polymethyl methacrylate (PMMA) denture teeth based on their chemical composition when opposed by a ceramic ...
Tensile bond strength of glass fiber posts luted with different cements
Bonfante,Gerson; Kaizer,Osvaldo Bazzan; Pegoraro,Luiz Fernando; Valle,Accácio Lins doProper selection of the luting agent is fundamental to avoid failure due to lack of retention in post-retained crowns. The objective of this study was to investigate the tensile bond strength and failure mode of glass fiber posts luted with different cements. Glass fiber posts were luted in 40 mandibular premolars, divided into 4 groups (n = 10): Group 1 - resin-modified glass ionomer RelyX Luting; Group 2 - re...
Fracture resistance and failure pattern of teeth submitted to internal bleachin...
Bonfante,Gerson; Kaizer,Osvaldo Bazzan; Pegoraro,Luiz Fernando; Valle,Accácio Lins doOBJECTIVE: This study investigated the compressive fracture strength and failure pattern in premolars submitted to endodontic treatment and internal bleaching with 37% carbamide peroxide for 21 days, with application of different restorative procedures. MATERIAL AND METHODS: Six groups were employed (n = 10): 1) non-bleached teeth and pulp chamber sealed with IRM; 2) bleached teeth and pulp chamber sealed with ...
