Removable partial dentures (RPD) demand specific hygienic cleaning and the combination of brushing with immersion in chemical solutions has been most recommended method for control biofilm. However, effect cleansers on metallic components not widely investigated. This study evaluated different surface RPD. Five disc specimens (12 mm x 3 centered a 38 18 4 mould filled resin) were obtained each experimental situation: 6 [Periogard (PE), Cepacol (CE), Corega Tabs (CT), Medical Interporous...

This study evaluated colour stability, surface roughness and flexural strength of microwave-polymerised acrylic resin after overnight immersion in sodium hypochlorite, simulating 180 days use.Forty disc-shaped (15 mm x 4 mm) 40 rectangular specimens (65 10 3 were prepared from resin. The immersed 0.5, 1% Clorox/Calgon distilled water. Colour measurements (ΔE) determined by a portable colorimeter. A analyser was used to measure (μm). (MPa) measured using three-point bending test universal...

This study evaluated the color stability, surface roughness and flexural strength of a microwave-polymerized acrylic resin after immersion in sodium hypochlorite (NaOCl), simulating 20 min disinfection daily during 180 days. Forty disk-shaped (15 x 4 mm) 40 rectangular (65 10 3 specimens were prepared with (Onda-Cryl). Specimens immersed either 0.5% NaOCl, 1% Clorox/Calgon distilled water (control). Color measurements determined by portable colorimeter. Three parallel lines, separated 1.0...

OBJECTIVE: Removable partial dentures (RPD) require different hygiene care, and association of brushing chemical cleansing is the most recommended to control biofilm formation. However, effect cleansers has not been evaluated in RPD metallic components. The aim this study was evaluate vitro denture on weight ion release RPD. MATERIAL AND METHODS: Five specimens (12x3 mm disc positioned a 38x18x4 mould filled with resin), 7 cleanser agents [Periogard (PE), Cepacol (CE), Corega Tabs (CT),...

This study analyzed the weight loss and surface roughness caused in Plexiglass specimens by conventional dentifrices (Sorriso, Colgate Close Up) specific used for cleaning of dentures (Corega Dentu Creme). were divided into 6 groups (n=6) including: a control (distilled water - DW) experimental groups. Brushing was performed toothbrushing machine with soft brush dentifrice suspension DW according to different brushing times (50, 100, 200 250 min -18,000, 36,000, 72,000 90,000 cycles,...

Chemical disinfectants are usually associated with mechanical methods to remove stains and reduce biofilm formation. This study evaluated the effect of on release metal ions surface roughness commercially pure titanium, alloys, heat-polymerized acrylic resin, simulating 180 immersion trials. Disk-shaped specimens were fabricated titanium (Tritan), nickel-chromium-molybdenum-titanium (Vi-Star), nickel-chromium (Fit Cast-SB Plus), nickel-chromium-beryllium Cast-V) alloys. Each cast disk was...

This study evaluated the effect of cleanser solutions on color heat-polymerized acrylic resin (HPAR) and brightness dental alloys with 180 immersion trials. Disk-shaped specimens were made I) commercially pure titanium, II) nickel-chromium-molybdenum-titanium, III) nickel-chromium molybdenum, IV) nickel-chromium-molybdenum beryllium. Each cast disk was invested in flasks, incorporating metal into HPAR. The (n=5) then immersed containing: 0.05% sodium hypochlorite, 0.12% chlorhexidine...

The current study evaluated prosthetic dental crowns obtained by optical scanning and a computer-aided designing/computer-aided manufacturing system using micro-computed tomography to compare the marginal fit. virtual models were with four different surfaces: typodont (T), regular impressions (RI), master casts (MC), powdered (PMC). Five for each group. For model, crown was designed on software milled from feldspathic ceramic blocks. Micro-CT images gap measurements data statistically...

The aim of this study was to evaluate the integrity external hexagon an implant system with internal and hexagons but prosthetic connection through (Internal Torque, IT) in comparison that mount (External Hexagon, EH). A device made measure rotational freedom angles between abutment 10 implants from each group after application surgical placement torques 45, 60 80 Ncm simulating locking. distances vertices were also obtained. Rotational data subjected ANOVA Tukey's test (P < .05) showing no...

To evaluate the influence of Morse taper implant index on microleakage.Thirty implants and abutments were divided into 3 groups (n = 10): CM1 (universal post without index), CM2 with CM3 (abutment index). microleakage from inner part, inoculated Streptococcus sanguinis solution at a 0.5 McFarland incubated for 7 days 37°C in Eppendorf tubes sterile broth. part implant, these Schaedler broth immersed Fusobacterium nucleatum McFarland. The samples 30 an anaerobic chamber.Nine each group first...

The aim of this prospective clinical study was to evaluate patient rehabilitation with two immediately loaded implants and bar-retained mandibular overdentures after 48 months follow-up. Twenty patients were treated each; these, 17 re-evaluated for comparison. Gender, age, plaque index, gingival inflammation, keratinized mucosa, probing depth, bleeding, implant loss data recorded, periapical radiographs obtained measurement marginal bone loss. results statistically analyzed one-way analysis...

Purpose: The current study evaluated two different materials, using micro-CT to compare the marginal gap of feldspathic ceramic (V) and resin nano-ceramic (L) crowns obtained by computer-aided design/computer-aided manufacturing (CAD/CAM) systems, CEREC CAD/CAM system E4D Technologies. Methods: A human lower left first premolar was mounted on a typodont model prepared for an all-ceramic crown. Two groups (n = 5) were divided based obtaining material used it (V L). Micro-CT images...

Several studies have suggested that athletes with disabilities experience more difficulties having access to oral health care than the population in general. The aim of this study was estimate impact socio-demographic/socio-economic factors, hygiene habits and clinical conditions on OHRQoL – Oral Health-Related Quality Life (assessed Health Impact Profile 14 OHIP-14) a sample heterogeneous types disabilities. Altogether, 105 were evaluated. Cross-sectional data collected including interviews...
