Repair bond strengths of non-aged and aged resin nanoceramics
PURPOSE To explore the influence of different surface conditionings on surface changes and the influence of surface treatments and aging on the bond strengths of composites to non-aged and aged resin nanoceramics. MATERIALS AND METHODS Rectangular-shaped non-aged and aged (5000 thermocycles) resin nanoceramic specimens (Lava Ultimate) (n=63, each) were divided into 3 groups according to surfa...
متن کاملeffects of three surface conditioning techniques on repair bond strength of nanohybrid and nanofi lled composites
background: repair bond strength of different composite resins has been assessed in few studies. in addition, reports on the effi cacy of surface treatments are debated. therefore, this in vitro study was conducted to evaluate the effect of three surface treatments on two nanocomposites versus a microhybrid composite. materials and methods: in this experimental study, 135 composite blocks (45 s...
متن کاملEffects of 0.2% Chlorhexidine and Re-polishing on the Color Stability of Nanofilled Composite Resins
Introduction: The growing demand for esthetic dental procedures has resulted in the increased development of new restorative composite resins. The success of composite resin restorations depends on their color stability over time. The present study aimed to evaluate the effects of 0.2% chlorhexidine (CHX) and re-polishing on the color stability of nanofilled composite re...
متن کاملDegree of conversion of nanofilled and microhybrid composite resins photo-activated by different generations of LEDs
OBJECTIVE This study aimed at evaluating the degree of conversion (DC) of four composite resins, being one nanofilled and 3 microhybrid resins, photo-activated with second- and third-generation light-emitting diodes (LEDs). MATERIAL AND METHODS Filtek™ Z350 nanofilled composite resins and Amelogen® Plus, Vit-l-escence™ and Opallis microhybrid resins were photo-activated with two second-genera...
متن کاملthe effects of planning on accuracy and complexity of iranian efl students’ written narrative task performance
this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
