background: this study was designed to compare the clinical performance of composite, strip crowns, biological restoration, and composite with stainless steel band when used for the coronal build-up of anterior teeth. materials and methods: a total of 20 patients aged 3-6 years presenting with mutilated primary anterior teeth due to caries or trauma were selected for the study using randomized ...

statement of the problem: optical properties of the composite resins, concerning their translucency and thickness, are affected by discolored tooth structure or inherent darkness of the oral cavity. purpose: this study aimed to compare the translucency parameter (tp) of five different composite resins in different thicknesses and to evaluate their masking ability in black backgrounds. materials...

OBJECTIVES Color change of composite restorations is well known to dentists. However, the effect of commonly consumed drinks on discoloration of composite resins has yet to be determined. This study sought to assess the color change of a nanofilled (Premise) and a flowable composite resin (Premise flowable) following simulated consumption of tea, cola, iron drops and multivitamin syrup. MATER...

The brightness and color of a surface depends on its contrast with nearby surfaces. For example, a gray surface can appear very light when surrounded by a black surface or dark when surrounded by a white surface. Some theories suggest that perceived surface brightness and color is represented explicitly by neural signals in cortical visual field maps; these neural signals are not initiated by t...

POTTING patterns serve as one approach in the study of gene action. S A superficial character, such as pigmentation, presumably is closer to primary gene action than are the more fundamental aspects of embryonic development. The spotting problem, concerned with the localization of color, is to be distinguished from the pigment problem concerned with the quality and intensity of color. The prese...

replacement and reattachment of a newly detached composite tooth pontic is sometimes justified because of shape, color, function and patient satisfaction. the aim of this case report is to describe a new method using rigid tray technique for exact replacement and reattachment of acceptable detached composite tooth pontic

objectives : studies on the effect of coloring procedures on the bond strength of zirconia to resin cement are lacking in the literature. this study evaluated the effect of dipping of zirconia ceramic in different liquid color shades on the microtensile bond strength (mtbs) of zirconia ceramic to resin cement. materials and methods: this in vitro study was conducted on 100 microbar specimens di...
