PURPOSE To evaluate the influence of previous acid etching on bond strength a self-etch universal adhesive system sound and eroded enamel dentin. MATERIALS AND METHODS Flat dentin surfaces were obtained from bovine incisors (n = 44) divided into two groups according to exposure erosive conditions: (without erosion) (after challenge with 0.3% citric acid, pH 2.6, 5 min, 4x/day, 5 days). Each group was then subgroups (n = 11) application or not 37% phosphoric before applying adhesive. Single...
Based on the development of adhesive dentistry, minimally invasive restorations in ceramics are used as alternativesto restore a tooth. Dental largely applied dentistry field mainly due to their esthetic andmechanical strength. One ceramic properties be well known before its use is wear resistance thatshould compatible with antagonist behavior avoid unwanted performance. Therefore, severalmethods have been performed assess materials considering different conditionspresent complex oral...
Changes in the organic matrix of composite resins have been proposed to improve their surface properties. However, polishing systems may perform differently different materials. This study compared effect on roughness four containing resin monomers: Admira Fusion (nanohybrid pure ormocer), Aura Bulkfill Bis-GMA, UDMA), Charisma Diamond TCD-DI-HEA) and Vittra APS (nanofilled UDMA). Cylinders (N = 120, n 10) were prepared from each material top specimen was grounded using a diamond finishing...
This study investigated the protective effect of experimental solutions containing 4 polymers (polyoxirane, hydroxypropylmethylcellulose [HPMC], pectin, and an amino methacrylate copolymer [AMC]) in 2 concentrations (low high) associated or not with sodium fluoride (F; 225 ppm F<sup>–</sup>) plus stannous chloride (FS; 800 Sn<sup>2+</sup>) on dissolution hydroxyapatite crystals (HA). Deionized water was control. The pretreated HA added to a 0.3% citric acid solution...
This in vitro study investigated whether Carbopol 980 polymer could potentiate the anti-erosive effect of solutions containing sodium fluoride (F) and associated with stannous chloride (FS). The dissolution hydroxyapatite treated experimental (F [500 ppm F<sup>–</sup>], F + [0.1%], FS F<sup>–</sup> 800 Sn<sup>2+</sup>], Carbopol) was evaluated. Deionized water negative control, a commercial mouth rinse (AmF/NaF/SnCl<sub>2</sub>; 500...
Objective: Assessment of the influence theultrasound and irrigant solutions on bondstrength (BS) glass fiber posts. Material andMethods: Sixty-six roots bovine teeth standardizedat 16 mm were used. The submitted to abiomechanical preparation up size #80 Kerr file,with irrigation 5ml saline solution at everyfile change then filled. canals underwentpartial desobturation divided into 6 groupsaccording use ofultrasound prior post cementation: S – salinesolution; C 2% chlorhexidine solution; H...
This study evaluated the effect of solutions containing aminomethacrylate copolymer (AA) and sodium fluoride (F; 225 ppm F
ABSTRACT Aim The aim of this study was to investigate the effects pretreatment different irrigating solutions with and without application Nd: YAG laser on bond strength (RU) adhesion fiberglass post relined resin composite root dentin. Materials methods Sixty-six single bovine incisor roots were divided into 6 groups according solution with/without apllication after canal filling: S- saline; C-2% chlorhexidine solution, H-2.5% sodium hypochlorite; SL-saline + laser, CL-2% laser; HL-2.5%...
The clinical success of tooth-colored indirect restorations has been confirmed in several studies. However, inlays andonlays Class II cavities with deep gingival margins can still be considered a challenge. Withthe purpose facilitating the execution operative procedures intrasulcular and reducing riskof restorative failures, technique cervical margin relocation explored as noninvasive alternative tosurgical crown lengthening. This work aims at discussing through case report biomechanical,...
Microscopy has been widely used to complement the data of studies related dentin bonding; however, different specimen preparation methods may influence analysis. Aiming contribute reported scenario, this study evaluated effect two specimen-sectioning (cleavage and diamond disk cut) on quality scanning electron microscopy (SEM) images. Four crowns human molars were selected had an area approximately 6 mm2 exposed. They then divided into groups according universal adhesive application: total...
A Hipomineralização Molar Incisivo (HMI) é uma condição caracterizada pela redução da mineralização de molares e incisivos permanentes. Sua etiologia ainda não foi totalmente definida o diagnóstico pode ser desafiador ao cirurgião-dentista. As consequências vão desde hipersensibilidade dentinária até fratura do dente afetado. Novas técnicas materiais para tratamento dos dentes hipomineralizados têm sido desenvolvidos visando melhorar a qualidade vida paciente. No entanto, há um protocolo...
Objective: Evaluate the protective effect of artificial saliva formulations associated or not with mucin on dentin. Materials and Methods: Bovine dentin specimens were randomly allocated to 10 groups (n = 20) according tested presence absence mucin: Amaechi et al. (1998); Klimek (1982); Vieira (2005) Eisenburger (2001) deionized water (control). Samples submitted an erosive cycle consisting two immersions 120 min in saliva, followed by 1 hydrochloric acid solution, new storage for min....
Objective: The prevalence of non-carious cervical lesions (NCCLs) has increased in the recent years, especially elderly population. successful prevention and treatment those requires an understanding biomechanics aged teeth. Considering importance such aspect, impact age-related dentin deposition on stress distribution NCCLs was evaluated by means finite element analysis. Material Methods: A 2-dimensional model a sound maxillary first premolar created using CAD software. Two tooth geometries...
