Abstract Background Recently, a new generation of high-strength flowable dental composites has been introduced by manufacturers. The manufacturers claim that these materials have enhanced mechanical and physical properties are suitable for use in wide range direct anterior posterior restorations, even high-stress bearing areas. Aim objective this study was to assess certain recently comparison conventional multipurpose composites. Methods Four types (Genial Universal FLO, Gaenial Injectable,...
Background: We aim to evaluate the effect of surface conditioning, bonding agents and composite types on roughness (SR) shear bond strength (SBS) clear aligner attachments bonded ceramics. Methods: One hundred eighty IPS e.max CAD specimens were prepared. For SR, 60 divided according conditioning (n = 15) into four groups: control, 9.6% hydrofluoric acid (HFA), 37% phosphoric (PhA), air abrasion (AA). SR was measured using a Profilometer Atomic Force Microscopy. SBS, 120 methods 40) (9.6%...
Background:Dentin contamination with hemostatic agents before bonding indirect restorations negatively affects the bond strength.However, consensus on which materials could be used to clean of has not been explored.The aim this study was assess effect Katana Cleaner applied surface dentin contaminated shear strength (SBS) self-adhesive resin cement by comparing it three other cleaners. Material/Methods:Ninety specimens were divided into a no group (control) (n=10), 4 groups 25% aluminum...
Increasing the bond strength between orthodontic brackets and all-ceramic materials is one of challenges facing orthodontists. The purpose this study to assess shear (SBS) metal two types all ceramic using various surface mechanical chemical conditioning methods.Sixty blocks were prepared (IPS e.max VITA Suprinity® PC) treated with 3 treatments; etching 9.6% hydrofluoric acid (HFA) for 2 mins; roughening Sof-Lex finishing discs; discs HFA. Metal attached light cure adhesive. Samples...
This study compares the FEA-calculated stresses generated within supporting periodontal structure of a mandibular second molar restored with full ceramic crown and porcelain-fused-to-metal (PFM) crown, each resisting occlusal forces acting at different inclinations.Three-dimensional finite element models representing an unrestored two relevant restoration designs were constructed. Two represented PFM cemented same resin cement. Occlusion was assumed three contact areas, which equally shared...
Background: Preserving the strength and durability of dentin bonds is a concern dental researchers practitioners. Objective: The aim this study was to investigate effect treating etched with vitamin C curcumin suspension as cross-linking agents on shear bond universal adhesive. Methods: Extracted human third molar teeth were collected. Fifty-six flat coronal surfaces divided equally into four groups: (1) treated adhesives; (2) 37% H 3 PO 4 for 10s before application (3) same group (2), but...
During restoring class II and V cavities with resin composite, hemostatic agents are frequently used to control gingival bleeding and/or fluid provide a dry field which is crucial for efficient bonding. Hemostatic may adversely affect the bonding procedure, thus their removal prior essential. The current study evaluates effect of two different dentin cleansing protocols on shear bond strength composite using universal adhesive. Ninety premolars were sectioned expose coronal dentinal surfaces...
The aim of the study was to investigate influence dentin surface preparation with acid etching or chitosan treatment on wettability and shear bond strength resin composite using self-etch adhesive.Methods: Fifteen human sound extracted third molars were used in study.Dentin disks cut from crown for evaluation wettability, remaining part test.Dentin discs divided randomly into 3 groups (n=5) treated as follow: G1: control, G2: etched 32% phosphoric acid, G3: Chitosan 60 s.Contact angle...
Copper oxide containing phosphate glasses showed an antibacterial action against streptococcus sanguis, mutans and staphylococcus epidermidis. This study aimed to investigate the effect of adding copper glass particles (0- 25 wt%) into flowable composites (Filtek Z350XT Fusio liquid dentin dental flowable) induce properties. Surface (contact angle Vicker hardness number) mechanical (flexure strength, strain modulus) properties modified have been tested throughout this study; will be in...
To evaluate the flexure strength and modulus of nano-filled dental composite after different storage conditions.Two nano-composite materials were investigated (Filtek Z350 Tetric N Ceram). Composite bars (n=15) prepared from each material using Teflon mold with dimensions (2 x 2 25 mm). Samples randomly subdivided into three groups according to condition (dry, distilled water, thermo-cycled).
Sickle cell anemia patients with dental anomalies represent a difficult challenge for the prosthetic dentist.Proper treatment planning medical and management of these are important prerequisites successful results.This case report describes full-mouth rehabilitation sickle patient worn-down dentition including planning, consultation, correction vertical dimensions occlusion, preparation, restoration porcelain fused to metal crowns.
