Composite restorations have higher failure rates, more recurrent caries and increased frequency of replacement as compared to dental amalgam. Penetration bacterial enzymes, oral fluids, bacteria into the crevices between tooth composite undermines restoration leads decay failure. The gingival margin is particularly vulnerable at this margin, adhesive its seal dentin provides primary barrier prepared environment. intent article examine physico-chemical factors that affect integrity durability...
The aim of this study was to investigate the influence Nd:YAG laser on shear bond strength enamel and dentin total self-etch adhesives when applied over adhesives, before they were photopolymerized, in an attempt create a new bonding layer by dentin-adhesive melting.One-hundred twenty bovine incisors ground obtain flat surfaces. Specimens divided into two substrate groups (n=60): E (enamel) D (dentin). Each group subdivided four (n=15), according surface treatment accomplished: X (Xeno III...
SUMMARY Objectives: This study aimed to evaluate the bonding performance of a universal adhesive used according self-etching or etch-and-rinse protocols in noncarious cervical lesions (NCCLs) and compare two with their respective gold standard techniques. Methods Materials: randomized, double-blind clinical enrolled 34 participants who met inclusion criteria, 29 whom returned after years. They received 152 restorations bonded one three adhesives (Scotchbond Universal Adhesive, Adper Single...
The purpose of the present study was to investigate effects ND:YLF laser irradiation (1.31 J/cm2; 250 mJ per pulse), acid etching, and hypermineralization on shear bond strength (SBS) Scotchbond Multi-Purpose Plus (3M Dental Products) bonding system.Previous studies had shown that pretreatment dentin substrate with can influence SBS.Sixty bovine incisors were selected stored at -18 degrees C. Dentinal buccal surface exposed radiographs taken control thickness. specimens separated into 2...
Abstract Aim To evaluate ex vivo effectiveness of the three formulations bleaching materials for intracoronal root filled teeth using walking bleach technique. Methodology Extracted premolar were stained artificially with human blood. After biomechanical preparation, canals and a 3‐mm thick intermediate base zinc phosphate cement was placed at level cementoenamel junction. The divided into four groups ( n = 12): C (control, without material), A1 (sodium perborate + distilled water), A2 10%...
The aim of this study was to evaluate the fracture resistance ceramic plates cemented dentin as a function resin cement film thickness.Ceramic (1 and 2 mm thicknesses) were bovine using composite cement. thicknesses used approximately 100, 200, 300 microm. Noncemented control. Fracture loads (N) obtained by compressing steel indenter in center plates. ANOVA Tukey tests (alpha= 0.05) for each thickness compare among films used.Mean load 1-mm were: control-26 (7); 100 microm-743 (150); 200...
Abstract Background The current study presents the effort of a global collaborative group to review management and outcomes malignant tumors skull base worldwide. Patients methods A total 28 institutions contributed data on 3061 patients. Analysis evaluated clinical variables, survival outcomes, multivariable factors associated with outcomes. Results median age was 56 years (IQR 44–67). open surgical approach used in 55% ( n = 1680) cases, endoscopic resection performed 36% 1087), combined...
Background: Dental caries and periodontal disease are admittedly the most common oral diseases one of main health problems, affecting quality life individuals. The aim this study was to evaluate patient’s education level knowledge on dental treatment caries/periodontal hygiene through a specific questionnaire. Materials Methods: A group 600 adults aged between 18 80 years old were evaluated. After evaluation answers given, participants in survey instructed regarding preventive measures....
Several anti-proteolytic dentin therapies are being exhaustively studied in an attempt to reduce bond degradation and improve clinical performance longevity of adhesive restorations. Objectives This study assessed the effect epigallocatechin-3-gallate (EGCG) on long-term strength when incorporated into adhesives. Material Methods Adhesive systems were formulated with EGCG concentrations 0 wt%: (no EGCG; control); 0.5 wt% 1.0 EGCG, 1.5 EGCG. Flexural (FS), modulus elasticity (ME), resilience...
This study evaluated the prevalence of chewing side preference (CSP) in deciduous, mixed and permanent dentitions.Three-hundred subjects were divided three groups (n = 100): Group 1 - children with deciduous dentition; group 2-children 3 dentition. The CSP was determined using a direct method (visual observation) developed by McDonnell et al. (2004). Descriptive statistic used to observe CSP. Pearson's Chi-square investigate signicant associations between gender, presence preferred...
The current outbreak of coronavirus 2019 (COVID-19) challenges how professional standards have been defined so far. In Dentistry, biosafety measures already taken by professionals intensified, aiming to offer the patient urgent and emergency treatment with safety for both. this context, Restorative Dentistry is responsible care patients caries injuries, or without symptoms and, fractures teeth existing restorations. This article guides professionals, during pandemic period, on risks involved...
The purpose of the present study was to evaluate in vitro degree marginal leakage Class V cavities involving cementoenamel junction. Cavities were 4 mm wide and 2 deep. specimens received dentin pretreatment (37% phosphoric acid) followed by Single Bond (3M) adhesive system application. 40 then divided into four groups: Group 1 (control); (Nd:YAG laser at 120 mJ/pulse, frequency 10 Hz, power 1.2 W); 3 140 1.4 160 1.6 W). restored with Z100 composite resin light cured 300-600 mW/cm2...
The aim of this study was to investigate the effects Er:YAG and Nd:YAG lasers on shear bond strength composite resin dentin. coronal portion 56 human molars divided into three parts, dentin thickness standardized at 2 mm. A 3-mm hole marked in center each tooth with sealing tape paper. specimens (n = 14) were then four groups: (1) acid etching + Single Bond (SB) (control), (2) SB laser irradiation (before adhesive curing), (3) thermal SB, (4) curing). cylinder built delimited area for...
The aim of this study was to evaluate the fluorescence intensity different composite resins and compare those values with dental tissues. Different were used make 10 discs (2 mm in depth 4 diameter) each brand, divided into groups: 1) Z (Filtek Z350, 3M ESPE), 2) ES (Esthet-X, Dentsply), 3) A (Amelogen Plus, Ultradent), 4) DVS (Durafill-VS, Heraeus Kulzer) 2 resin for enamel (A2), 5) OES ([Esthet-X] opaque-OA [1 mm] + enamel-A2 mm]); 6) ODVSI ([Charisma-Opal/Durafill-VSI], opaque-OM (1 mm)...
There are several methods for identifying carious dentinal tissue aiming to avoid removal of healthy tissue. OBJECTIVES: The purpose this study was test different the detection regarding amount removed and remaining dentin microhardness after caries removal. MATERIAL AND METHODS: surfaces 20 bovine teeth were exposed half surface protected with nail polish. Cariogenic challenge performed by immersion in a demineralizing solution 14 days. After transverse cross-section crown, specimens...
ABSTRACT Introduction This study evaluated the fluorescence intensity (FI) of different brands composite resins (CRs) and compare those values with FI human tooth, under action cigarette smoke (CI), coffee (CA), soft drink (CO), measured by direct spectrometry. Materials methods A total 30 specimens each brand (Filtek Z350, Esthet-X, Amelogen, Durafill) were made. Others tooth (3 mm/diameter) obtained from molars using a trephine bur.
